RIVER FIGHTS: Vietnam War

USNFVSome Background

Following the French defeat at Dien Bien Phu in 1954, the United States Military Assistance Advisory Group (Indochina) (USMAAG Indochina) became USMAAG (Vietnam) and with this transition, the United States became even more deeply involved in the affairs and prerogatives of the South Vietnamese (Republic of Vietnam) regime.  Wisely, President Eisenhower firmly resisted the urgings of some advisors to send in troops, but he did expand the role of military advisors and in time, all US armed services were represented on the USMAAG (Vietnam) staff.

In 1960, newly elected John F. Kennedy approved the USMAAG’s request for increases in the size of the South Vietnamese Army (also, Army of the Republic of Vietnam or ARVN) and an increase in the number of military and civilian advisors.  As Henry Bohn told us in 1855, the road to hell is paved with good intentions.  John Kennedy began excavating a hole our government couldn’t stop digging.

Lay of the Land

The Mekong Delta extends from Saigon (now, Ho Chi Minh City) south and west to the Gulf of Thailand and the border with Cambodia.  Its area extends nearly 29,000 square miles and it is home to an estimated 15 million inhabitants.  In all, the Mekong Delta constitutes about a quarter of the total land area and half the population of the former Republic of Vietnam.  The Delta is a flat alluvial plain created by the Mekong River, a land surface covered by rice paddies, which makes this region one of the world’s most productive rice-growing areas.  It is by far the most important agricultural region in Vietnam.

In terms of overland communication, the Mekong Delta was an unmitigated disaster, as the region is intersected by a complex network of waterways and inundated by heavy rain and seasonal floods.  In 1960, there was but one major hard surface road, which extended from Saigon to Ca Mau. Secondary roads were either poorly surfaced or unattended.  While the land facilitated air combat operations, poor road systems, rice paddies, canals, wide ditches, and rivers complicated ground operations.  In contrast, the waterway system was very sophisticated, and the US MAAG realized early on that if the US intended to pacify the Mekong Delta (also, IV Corps Tactical Zone, or IV CTZ), it would have to consider implementing riverine operations.

Most Vietnamese in this area are concentrated along waterways that constitute the principal transportation routes, on average, around 400 people per square mile.  Typically, Vietnamese homes are surrounded by dense trees, shrubs, and bushes —cultivated for fruit, shade, or decoration.  The vegetation was pleasing to look at, but it also gave protection and concealment to communist insurgents.  When planning for operations in the IV CTZ, US military officers wanted to take the war to the enemy but do so without endangering local inhabitants.  With its population density, it was nearly impossible to move friendly forces without their being observed by unfriendly eyes.  The enemy always seemed to know when Uncle Sam was coming for a visit.

Vietnam’s Delta seacoasts have an extensive network of mangrove swamps.  Vegetation on the coastal mudflats is dense, root structure high, and tangled, which makes access difficult and cross-country movements challenging.  Rice paddies are separated by thickets of trees in varied patterns.  Large cultivated plantations are marked by rows of palm trees, many of which border deep ditches or wide canals.  Operational planners for riverine operations had to factor in water, vegetation, terrain, and the influence of sea tides; it also involved guesswork.  There was no way to accurately predict travel or operational times. 

The Enemy

The Mekong Delta (IV CTZ) was rife with communist insurgents … estimated at around 84,000 men in 1966.  Of those, around 20,000 were trained and well-armed combat troops with about 51,000 part-time guerrillas.  In 1966, there were no North Vietnamese Army (NVA) forces operating in IV Corps.  Logistically, Viet Cong forces relied on support from local populations and whatever could be provided from North Vietnam.  Cambodia, bordering IV CTZ, was a haven for supplies moving down from the north.

Friendlies

ARVN forces in IV CTZ were subdivided into three divisional tactical zones: in the north, the 7th ARVN Division at My Thơ, in the center, the 9th ARVN Division at Sa Dec, and in the south, the 21st ARVN Division at Bac Lieu.  In total, around 40,000 men, including five ranger battalions and three armored cavalry squadrons.  Regular forces were augmented by Regional, Popular, and Irregular troops, and the National Police[1].  The conventional wisdom (back then) was that anyone joining Regional or Popular Forces organizations was “just asking for it” (VC assassination).  Unsurprisingly, both groups had high desertion rates, and the thing that made irregular troops so irregular was that one could never find them when they were needed.

Vietnamese naval forces in the 4th Naval Zone evolved from the French Dinassauts and included six river assault groups and eleven coastal groups that formed the so-called Junk Fleet.  Assault groups fell under the IV CTZ Commander; their primary mission was supporting ARVN riverine operations.  Each group could lift an ARVN infantry battalion.  In 1966, these units were used in their primary role about 10% of the time.  The reason for this was that the ARVN battalion commanders preferred airmobile operations; they were more fun and had greater visibility for purposes of promotion.

US Forces

United States Navy advisors entered the Mekong Delta in 1957 to replace the withdrawing French.  By 1966, the military advisory effort infused the entire RVN military structure.  In total, around 2,700 officers and enlisted men representing the Army, Navy, Marine Corps, and Air Force were assigned to corps, division, and provincial organizations, and the IV CTZ Area Logistics Command.  The USN Advisory Group (RVN) provided advisors to the Vietnamese Navy’s six river assault groups and eleven coastal groups.

In 1965, the U. S. Army’s 13th Combat Aviation Battalion was assigned to the Delta to support ARVN operations; by August of that year, the battalion operated four assault helicopter companies and one air reconnaissance company.  By mid-1966, naval forces included TASK FORCE 115 (also, MARKET TIME) and TASK FORCE 116 (also, GAME WARDEN).  The mission assigned to Market Time was interdiction of coastal areas to prevent resupply of VC forces by sea.  Game Warden was tasked with interdicting enemy lines of communications and assisting ARVN forces in repelling enemy attacks on river outposts of Regional and Popular Forces.  Despite the optimism of the American administration, which predicted a communist free Mekong Delta by mid-1965, about one-third of all communist attacks in South Vietnam in 1966 occurred within the IV CTZ; Viet Cong forces controlled about 25% of the population of the Delta.

To the Vietnamese high command in 1966, the question of whether a province was “pacified” was entirely political.  The American reality was that the South Vietnamese government-controlled, in total, only about four percent of the land in IV CTZ.  ARVN commanders bragged that they controlled these areas but if true, it was only during hours of daylight; the Viet Cong controlled the night.

Riverine warfare is an extension of sea power.  The Navy’s control of the sea enables it to project its strength ashore, including inland waterways, into the heart of the enemy territory.  None of the Navy’s resources operate inside a vacuum; the Navy works as a team.  In this example, blue water ships, amphibious forces, and its aviation arm all supported riverine operations.  It was Vietnam’s communist insurgency within a vast inland waterway that led the Navy to reexamine its previous successes in riverine operations.

A key strategy in confronting and then defeating a guerrilla force is isolation and interdiction.  US strategy in Vietnam involved denying guerrilla forces freedom of movement, access to the general population, the ability to withdraw into remote sanctuaries to regroup, and the ability to resupply.  U. S. Naval forces in Vietnam played a key role in achieving all these objectives.  Coastal surveillance programs formed a tight barrier against the infiltration of personnel, arms, and supplies from the sea.  Taking surveillance one step further, the rigid control of fishing areas diminished the insurgent’s ability to feed himself, and river patrols established protocols for the inspection of junks and sampans, which were the primary method of transporting people and goods over hundreds of miles of inland waterways.

No less important in combatting guerrilla forces is gathering intelligence, which is often a slow, painstaking process.  One must first locate the enemy before he can be eliminated.  Finding the enemy was often facilitated by nurturing relationships with local inhabitants, which was also a key element in riverine operations.

Highly mobile and well-armed riverine forces coordinated their activities with ground and air forces to interdict guerrilla activities.  The Navy’s shallow-draft patrol craft seized the initiative in carrying the fight to enemy sanctuaries far up the rivers and into canals —areas that had not been previously penetrated by French or ARVN ground units.  To achieve these goals, the Navy employed a variety of combat and combat-support organizations, each with unique but well-coordinated missions: River Patrol Force, Mobile Riverine Force, Coastal Surveillance Force, Naval Advisory Group, and strike campaigns dubbed OPERATION SEALORDS[2].

An Imposing Environment

As previously explained, riverine operations assume many shapes because inland waterways form unique challenges.  Vietnam’s inland waterways were at least a bewildering maze of interconnecting systems, so the Navy implemented a wide range of strategies to address them —made more difficult after the NVA began infiltrating South Vietnam in 1968.  At that time, the US Navy began looking for more than increasingly dispirited guerillas; they were looking for hard-core NVA regulars, as well.  The Mekong Delta was a paradise for guerrilla operations, which the NVA demonstrated could be just-as-easily implemented by regular forces.  Thick vegetation along the waterways limits visibility and offers excellent opportunities for ambush; floating vegetation and heavily silted waters concealed mines and other explosive devices.  Command detonated mines often signaled the beginning of hellacious firefights —some of these taking places within 50-75 feet of opposing forces.

There are three distinct regions within the Mekong Delta: Plains of Reeds, northwest of Saigon, which during seasonal floods lies beneath six feet of water, the Lower Mekong, which is a vast rice-growing region and the location of the imposing Ca Mau forest, and the mangrove swamps at the mouth of the Mekong adjacent to the Rung Sat (Forest of Assassins) Special Zone (RSSZ), which includes the main shipping channel to Saigon.  In the mangrove swamps, tides are extreme and vegetation so thick that men on the ground lose sight of each other four feet apart.

OPERATION JACKSTAY

On 26 February 1966, Viet Cong forces ambushed the SS Lorinda, a Panamanian-flagged coastal freighter on the Lòng Tàu River, about 18 miles south of Saigon.  The attack wounded six crewmen and caused the ship to veer off course and run aground.  This was not a trend the Americans could allow to develop.  Accordingly, Commander, U. S. Military Assistance Command, Vietnam (COMUSMACV) ordered a punitive raid against insurgents operating within the shipping channel approach to Saigon.

Navy and Marine Corps operational planners put together a blue water force off the coast of Vietnam, the first major U. S. Navy riverine operation in the Rung Sat Special Zone (RSSZ); it marked a major turning point in the unfolding saga of projecting American sea power from the high seas and coastal waterways into the vast waterways of the Mekong Delta.   Before this, the Navy’s participation in the river war was limited to inshore operations conducted by Swift Boats and Coastal Patrol Boats assigned to the Vietnamese Navy and their U. S. Navy advisors.  From this point forward, the Navy became increasingly involved in the river war.  The operation was designated JACKSTAY.

JACKSTAY underscored the versatility made possible by the domination of the wetlands, whether offshore or in-country.  The operation, conducted in two phases, was planned to decimate the Viet Cong in the RSSZ, a 400-square mile area of swamp particularly suited for clandestine operations.  The region of the RSSZ had harbored communist insurgents for well over a generation; it was where the Viet Minh/Cong manufactured weapons, where they treated their wounded, trained recruits, and stocked their supplies from North Vietnam.

1:5 Unit PatchJACKSTAY was a two-phased operation plan[3] that called for an assault on the Long Thanh Peninsula (RSSZ) by the 1st Battalion, 5th Marines (1/5) from ships operating off-shore: the USS Princeton, USS Pickaway, USS Alamo, USS Belle Grove, and USS Merrick.  USS Robison, GAME WARDEN swift boats, and MARKET TIME patrol boats provided naval gunfire support.  Air groups from USS Hancock provided helicopter lift and close air support.

The operation kicked off on the morning of 26 March 1966 with preliminary naval bombardments by Robison and aircraft from Hancock.  Navy Underwater Demolition Team (UDT) swimmers, preparatory airstrikes by Seventh Fleet carrier-based aircraft, and naval gunfire all supported the operation. Throughout, amphibious craft and coastal surveillance craft provided surveillance and blocking operations against Viet Cong escape.  The long inland reach of U. S. Navy sea power quickly adapted to operational complexities.

A Marine rifle company landed via surface craft near Dong Hoa on the western end of the peninsula with two additional companies executing a vertical assault at the center and on the eastern end.  The Marines encountered only scattered small arms resistance and soon established 21 four-man listening posts beyond their night perimeter.  During the night, VC attacked one of these posts initiating a firefight that resulted in two Marine KIAs and three enemies dead.  That same night, VC ambushed PCF-31[4] about one mile from Cần Giờ on the Long Thanh Peninsula, seriously injuring one crewman and severely damaging the patrol boat.

On 28 March, Marines made another unopposed surface assault on the Soài Rạp River, this time targeting an enemy logistics area on the Vam Sat River (linked to the headquarters element on the Soài Rạp River) and destroyed a cache of weapons that included over 1,000 grenades.

Higgins BoatFollowing airstrikes from the Hancock and naval gunfire from USS Henry County, USS Washoe County, and Ontos[5] fire from the deck of Henry County on 31 March, an 18-boat convoy entered the Vam Sat River.  Led by two Vietnamese-manned Higgins Boats[6], the convoy included two Vietnamese LCCPs rigged with chain drags and grapnels for minesweeping, and armored LCM-6 (equipped with mortars and automatic weapons), seven LCMs, a rifle company of Marines in two LCVPs, two LCPLs providing additional gunfire support, two LCM-3 salvage boats.  Helicopter gunships provided air cover.  Commander Derwin T. Lamb, USN commanded the convoy from the open deck of an LCPL positioned directly behind the Vietnamese minesweepers.  Captain John D. Westervelt, USN commanded the overall landing operation from an overhead helicopter.

As Lamb’s convoy approached the first bend of the Vam Sat River, Viet Cong command-detonated a crude electrical mine halfway between Lamb’s command LCP and the minesweepers.  An explosion reminiscent of Confederate torpedoes from a hundred years before reverberated across the water.  The craft escaped damage because they wisely hugged the shallows rather than navigating from the center of the channel.  The explosion signaled the commencement of intense small arms fire from the thick foliage on both banks.  Lamb led the convoy through the withering fire while all boats opened with their firepower.  Helicopter gunships strafed and rocketed VC positions about 100-yards inland, preventing the VC from bringing heavier guns to bear.  A mile further downriver, enemy fire became sporadic.

After landing a Marine rifle company in the heart of the dismal mangrove swamp, Lamb moved his convoy back up-river in the same formation to land two additional companies of Marines, who immediately disappeared into the thick underbrush.  When the Marines had completed their mission, LCMs (also, “Mike” boats) churned their way to shore, crashing their way through the overhanging tree limbs and into the dense undergrowth. Lowering the ramps cut an opening through the rotted vegetation, making it easier for the Marines to re-board.

During recovery operations, the convoy again ran into ineffective small arms fire.  The open LCMs, each carrying 60 Marines, may have been vulnerable targets were it not for the work of the gunships overhead and the fact that the VC riflemen were poor shooters.

JACKSTAY concluded on 6 April with the destruction of arms factories, training camps, a headquarters complex, and a makeshift hospital.  Large amounts of rice and other foods were captured, along with 60,000 rounds of ammunition and 300 pounds of gunpowder.  Sixty-three enemies were killed in the combined assaults, while American Marines lost five men killed in action.  Subsequently, Viet Cong activity decreased in this area of the Delta.

The results of JACKSTAY were far more significant than the 53 confirmed Viet Cong dead or the tons of material destroyed or captured.  Its success was laudable, of course, but so too was the projection of naval power into the heart of an enemy sanctuary.  As the Navy’s initial combined riverine operation, JACKSTAY served as a loud knock on the door to an enemy that had had its way in the RSSZ for far too long.  The message was unmistakable: the VC could run, and the enemy could hide, but they would not be able to elude the powerful arm of the United States Navy-Marine Corps team.  Ultimately, after scurrying around like rats, the communists would only die tired.

In the middle of JACKSTAY, on 1 April 1966, Rear Admiral Norvell G. Ward[7], USN assumed duty as Commander, U. S. Navy Forces, Vietnam (COMUSNAVFORV).  The purpose of NAVFORV was to consolidate several U. S. Navy programs under a single component command of the USMACV.  In addition to supervision of the support commands at Saigon and Da Nang, and the Navy Construction (Seabee) battalions, Ward assumed responsibility for missions assigned to the Naval Advisory Group, Coastal Surveillance Forces, and River Patrol Forces.  Mobile Riverine Force (TASK FORCE 117) was added in 1967.

RIVER FIGHTS: The Middle Years

War with Mexico

The US Navy added to its growing experience in inland operations during the Mexican War.  When hostilities began, Commodore David Conner, commanding the Home Squadron, blockaded the Mexican Gulf Coast.  The blockade forced the enemy to use inland waterways and overland routes to move supplies.  San Juan Bautista, 74 miles up the Tabasco River from Frontera, was a distribution center for contraband war materials.  The river had ample depth to accommodate large vessels but there were significant obstacles in planning for an assault.  The river’s current was strong, dense vegetation provided good cover for riflemen and snipers.  The river also took a sharp (and hazardous) “S” bend (called the Devil’s Turn) and there were two strategically placed forts guarding the approaches to San Juan Bautista.   Normally, sailing vessels alone would have little chance of success —but at this time, the US Navy was incorporating steam engines into the fleet.  The Home Squadron had several small steam-powered ships of war.

On 23 October 1846, a naval expeditionary force under Commodore Matthew C. Perry crossed the sand bar at Frontera and seized the town with little to no resistance.  Then, with three steamers and four other vessels, proceeded upriver to San Juan with a 200-man landing party.  The journey took around 33 hours.  Anticipated resistance 9 miles below San Juan never materialized because the Mexican garrisons fled as soon as they could see the American ships closing for action.

Arriving at San Juan before noon on 25 October, Perry demanded the town’s surrender.  When the Alcalde[1] returned an insolent reply, Perry fired on the central flag staff, destroying it.  Perry spared the town but to keep shipping out of the hands of insurgents and gun runners, he seized two Mexican steamers, five schooners, and several smaller craft.  When Mexican riflemen opened fire on Perry’s squadron, Perry had his cannon rake the streets, which effectively ended all interest in firing on the Americanos.  Neither of the two towns was occupied, but Frontera was blockaded for six months.  When the blockade was lifted, Mexican smugglers began their activities anew.

In mid-June 1847, Commodore Perry was ready to ascend the Tabasco River for the second time.  This time, Perry assembled a larger force.  An advocate of naval infantry drill and landing party training, Perry formed a naval brigade of 2,500 officers, seamen, and Marines.  Captain J. Mayo was appointed to command the brigade.  Perry’s squadron included four small steam warships, six schooners, bomb brigs, and numerous ships’ boats.

At the first elbow of the Devil’s Turn, lead ships encountered small arms fire from dense chaparral banks.  Ships’ fire silenced the shooters, but obstructions had been placed in the river around the turn.  Well-manned breastworks on the shore provided a Mexican firing platform.  After reconnoitering the obstructions, Perry landed his brigade for the nine-mile march overland to San Juan.

While Perry led his naval brigade through the swamps and  jungle, Lieutenant David Dixon Porter[2] assumed command of the flotilla and worked his ships through the obstructions.  Perry’s combined force successfully routed 600 Mexican troops at Accachappa and moved on to Fort Iturbide situated just below San Juan.  Fort Iturbide had a battery of six guns and 400 infantry troops.  Porter led the flotilla into Mexican fire and then, under the protective cover of ship’s cannonade, he released a landing party to assault the fort.  The Mexicans broke before the charge.  When Perry and the brigade arrived, the American flag was already flying above the fort.

In two separate instances, Perry demonstrated the value of coordinated tactical inland penetrations.  The operation against San Juan Bautista was a valuable lesson for the US Navy; it would come in handy again in the not-too-distant future.

The Rude War

The U. S. Navy’s main advantage over the Confederate States of America in 1861 was that the south had no navy at the beginning of the Civil War.  Accordingly, the Union navy had, and retained, its control of the sea at all stages of this conflict.  The U. S. Navy implemented three broad strategies: (a) naval blockade of southern coastal regions, (b) amphibious assault and capture of port cities and strong points, (c) splitting the Confederacy along the Mississippi River (and tributaries) and seizing inland waterways to crush Confederate resistance.  The Union navy’s effective 3,000-mile blockade and the imbalance of opposing naval forces resulted in its ability to focus on coastal and inland riverine operations[3].

Commander John D. Rodgers, placed in overall charge of riverine operations for the navy, selected vessels and readied a force under Army control in northwestern waters with its headquarters near Cairo, Illinois (at the confluence of the Ohio and Mississippi rivers).  From this location, Union vessels could influence river traffic in Illinois, Kentucky, and Missouri.  Rodgers purchased and converted river steamers into wooden gunboats: Tyler, Lexington, and Conestoga.  Through the War Department, Rodgers contracted for seven additional gunboats (named for the cities they would defend).  These “city class” vessels became the backbone of the river fleet.  They were 175-feet long, had a 50-foot beam, and the top deck was shielded with heavy armor.  Thirteen guns included old-fashioned 42-pounders (supplied by the Army), and 8-inch and 32-pound navy guns.

While the city class boats were under construction, the wooden gunboats made significant contributions to the Union effort.  These former sidewheelers, unarmored and vulnerable, could not have challenged a seagoing warship or stout fortification but they did achieve good results.  In a nation with few and exceedingly poor roads, they controlled the river highways.  Moreover, they provided mobility and speed of movement of troops and supplies, surprise attack, and flexibility in strategy and tactics, and rapid exchange of information between and among field commanders.

Strong southern sentiment permeated the Ohio and Mississippi river systems.  One effect of the gunboats was that they discouraged secessionists and gave confidence to Unionists.  Fence-sitters stayed out of the way.  Alfred Thayer Mahan[4] was convinced that the riverine force was of inestimable service in keeping alive attachment to the Union and preventing secession by Kentucky and Missouri.

The Battle of Belmont (Missouri) was joined on 7 November 1861, the first combat test in the Civil War for Brigadier General Ulysses S. Grant.  On 6 November, Grant moved his 3,000 troops by riverboat from Cairo to assault the Confederate outpost near Belmont, which was across the river from the rebel stronghold at Columbus, Kentucky.  Grant and his men went ashore on the Missouri side and marched overland to Belmont.  Grant succeeded in surprising and over-powering the Confederates[5], but they were quickly reorganized and reinforced by Major General Leonidas Polk.  Grants victory was short lived as Polk endeavored to cut off Grant’s withdrawal.  It was only through the gunboats that Grant and the Union survivors made good their escape[6].

River gunships were effective, but they could not aggress rebel fortifications.  This mission would fall to the semi-ironclad ships ordered by Rodgers, who was replaced by Flag Officer[7] Andrew Hull Foote, U. S. Navy.  Foote is remembered as an aggressive officer who, along with Grant, combined their forces to attack and defeat Fort Henry.  There could be no question among Confederate officers that they had no answer to the Navy’s riverine warfare strategy.

Damn the Torpedoes

As the Mississippi River Flotilla steadily beat the CSA Army and Navy into submission, Flag Officer David Glasgow Farragut[8] prepared for service in the Gulf of Mexico.  During his assault of New Orleans, Farragut moved his entire fleet up the Mississippi River to contest the heavy guns at Fort Jackson and Fort St. Philips.  During the five-day bombardment, Farragut employed a mortar flotilla built especially for riverine operations.  The rebels put up an exceptional defense of New Orleans but were eventually overpowered by Farragut’s relentless assault and the threat of Union guns over New Orleans’ levees convinced the citizens to submit to Union authority.  What made Farragut’s victory sweet was that New Orleans was the only southern city with a chance of matching the Union’s overwhelming riverine forces.

Meanwhile, behind Foote’s gunboats, one catastrophe after another descended upon the Confederates, whose armies could not match the Union advantages in riverine operations, which were expanded into the Tennessee River and down and across the state of Mississippi.  Rather than arteries of life for the Confederacy, they became highways of death.  Advancing behind the gunboats, Grant’s army cut off western Tennessee.  More than any other factor, gunboats were the deciding factor at the Battle of Shiloh.

From New Orleans, Farragut’s heavy ships, while suffering much damage in the restricted and turbulent Mississippi, forged ahead to Vicksburg, a mighty fortress with batteries situated high on the bluff where Farragut’s guns could not effectively reach.  And, with Confederate forces numbering around 33,000, it would take more than Farragut’s 3,500 men to defeat that fortress.  Eventually, after a siege lasting a year, Vicksburg did fall to Grant’s army of  77,000 men.  Confederate casualties numbered 32,687 (3,202 killed, wounded, or missing in action, 29,495 surrendered).

Thus far, the Navy demonstrated a sophisticated understanding of naval warfare on inland waters.  The Navy’s ability to control the sea made riverine warfare possible.  The Navy’s exercise of its control made riverine warfare flexible.  Seagoing ships were adapted to fight in lakes and rivers to oppose shore batteries.  The Navy learned not only how to build riverine vessels, it learned how to fight them through an appreciation for local environments and conditions and devising appropriate circumstantial responses.

In 1898, the U. S. Navy-Marine Corps was ready for the Spanish-American War.  The U. S. Army was not.  A few years later, the Navy dusted off the lessons it learned from previous periods and addressed head-on the challenges associated with the Philippine Insurrection and the Boxer Rebellion.  In the Philippines, riverine warfare facilitated an end to the violence.

In the early decades of the twentieth century, a flotilla of shallow draft gunboats protected American life and property in war-torn China.  Along more than 1,500-miles of the Yangtze River, riverine patrols faced hostile Chinese war lords, snipers, and bandits; landing parties were kept on a moment’s notice for intervention or defense.  Natural dangers, such as swift currents, fast rising tides, and navigational obstacles were as formidable as any encountered by Commodores Barney, Perry, or Farragut.

RIVER FIGHTS: The Early Days

The purpose of the United States Navy is to defend America’s shores; the best way of doing that is by prosecuting war in the other fellow’s backyard.  American sea power achieves its greatest advantage by keeping an enemy’s main force away from America’s shore.  Our Navy controls the oceans for America’s use; it denies to our every foe access to the oceans and skies.  The enemy’s coastline is America’s naval frontier.  Our history over the past few hundred years tells us that our Navy’s strategy has worked out quite well for the American people.

The U. S. Navy is no one-trick pony and naval warfare isn’t confined to vast oceans or hostile coastlines.  Whether projecting naval power at sea, in the air, or ashore, the Navy is prepared to employ the full spectrum of its arsenal: surface ships, submarines, amphibious ships, naval guns, sophisticated aircraft, missiles, and shallow draft watercraft.  And then, whenever our enemies need a real ass­-kicking, the Navy asks for a handful of Marines.

Our understanding of the past helps us to better serve the future.  Naval technology in our early days was somewhat limited to ships of the line, cutters, barges, experimental submarines, and small boats (craft suited to rivers and estuaries).  Today we refer to combat operations on rivers as “Riverine Warfare,” and the US Navy has been doing this since the Revolutionary War.  In the modern day, watercraft intended for this purpose is designed and constructed for a specific operational environment.  In earlier times, watercraft used for riverine operations involved whatever was readily available at the time. 

Revolutionary War

The first significant example of riverine operations occurred on Lake Champlain in 1775-76.  Lake Champlain is a 136-mile long lake with connecting waterways north into Canada and southward toward New York City.  They were waterways that offered a prime invasion route to early settlements and colonies and involved a bitter struggle through the end of the War of 1812.  Our revolutionary-period leaders understood that the British would attempt to separate New England from other colonies by controlling Lake Champlain waterways.  Ethan Allen and Benedict Arnold seized Ticonderoga on 19 May 1775 and Crown Point a few days later.  These were audacious operations that provided American patriots with badly needed cannon and munitions.

Arnold made a bold move to control Lake Champlain.  He hastily armed a captured schooner, pressed north to St. John’s on the Richelieu River, and in a pre-dawn riverine raid, surprised the British garrison.  He captured a 70-ton British sloop, seized numerous small boats, and helped himself to military stores, provisions, and arms before returning to Lake Champlain.  In one  stroke, the Americans had gained control of Lake Champlain, which thwarted British plans for their upcoming campaign season.

Arnold’s success at St. John’s was followed up with failure at Quebec, which precipitated the American evacuation of that city.  British and American interests initiated a vigorous ship/boat-building effort on Lake Champlain.  In the British mind, control of Lake Champlain had not been finally settled, but they did look upon Arnold as someone who needed their close attention.  For the British to utilize the Lake Champlain-Lake George-Hudson River highway to split the colonies, they had to first dispose of Arnold’s naval force.

From their base at St. John’s, the British rapidly constructed 29 vessels (some had been built in England and assembled in St. John’s).  The British squadron included Inflexible, Maria, Carleton, Thunderer, Loyal Convert, twenty gunboats, and four long boats.  Under Captain Thomas Pringle, the squadron commander, were 670 well-trained sailors and Marines.  In total, Pringle commanded 89 6-24-pound cannon.

The arms race of 1776 was on.  Spurred by the restless driving force of Benedict Arnold, the Americans sought to keep pace with the British at their Skenesborough shipyard, near the southern end of Lake Champlain.  They worked with scant resources, green timber, and a hastily assembled force of carpenters.  Drawing on his own experience as a sailor and his newly acquired knowledge of the waters in which he would fight, Arnold prepared specifications for a new type of gondola particularly suited to his task.  He wanted a small vessel of light construction that would be fast and agile under sail and oar. He hoped to offset the disadvantages of restricted waters with greater maneuverability against the slow moving, deeper draft British ships whose strength he could not match.

In all, Arnold fought fifteen American vessels, including the sloop Enterprise, the schooners Royal Savage, Revenge, and Liberty, eight of his newly designed gondolas, and three galleys.  He manned his squadron with 500 men from troops made available to him by General Philip Schuyler and from whatever was available from along waterfront taverns. With pitch still oozing out from the planking in his ships, Arnold, now a brigadier general, set a northward course.  On 10 October, Arnold stationed his flotilla west of Valcour Island where the water was deep enough for passage yet narrow enough to limit British access.  Pringle’s main failure was in conducting a proper reconnaissance of the area, so his fleet sailed past Valcour Island under a strong north wind, which required that he return direction from a leeward position.  The battle raged for most of the afternoon.  Arnold expended 75% of his munitions and his ships were badly cut up.  Taking advantage of the north wind and a foggy night, Arnold slipped through the anchored British ships and escaped.  By the 13th, British ships began to overhaul Arnolds fleet, or ran them aground.  Arnold managed to escape to Ticonderoga with six ships and the loss of (an estimated) 80 men.

Having regained control of Lake Champlain, the British quickly seized Crown Point.  General Horatio Gates and Arnold prepared to defend Ticonderoga but the British instead returned to Canada and went into winter quarters.  Circumstantially, Arnold had been thoroughly beaten on the “inland sea” but had scored a strategic victory.  A British advance southward was delayed for another year and the Continental Army had additional time to build its strength.

During the War of 1812, restricted naval warfare was again seen on Lake Erie and Lake Champlain.  This strategy also focused on inland waterways.  Initially, the British controlled the Great Lakes, which facilitated their capture of Detroit and the invasion of Ohio.  In September 1812, Commodore Isaac Chauncey, USN took command of the lakes along the Erie-Ontario frontier in order to thwart a British invasion from that direction.  Both sides strengthened their positions.  Master Commandant Oliver H. Perry, USN assumed command of all naval activity on Lake Erie, under the direction of Commodore Chauncey from Lake Ontario.  Commanding British naval forces was Commodore R. H. Barclay, RN operating on Lake Erie.  Barclay and Perry both began vigorous ship-building programs; neither side could well afford men or supplies, so corners were cut whenever possible.  Barclay had an advantage over Perry in ships, but through remarkable leadership and effort, Perry closed that gap.

On 10 September 1813, Perry joined Barclay in a desperate battle.  Perry had nine ships to Barclay’s six and an advantage in weight of broadside.  Barclay’s guns had a greater range, however, and Perry was always in danger of being destroyed.  In fact, Perry’s star came very close to setting on Lake Erie.  One of his two heavy ships failed to close with the British, rendering Perry’s flagship Lawrence a shamble.  Decks ran red with blood; 80% of his crew became casualties; defeat seemed inevitable—but not to Master Commandant Perry.  Embarking with a courageous boat crew, he rowed across the shot-splashed water, boarded the uninjured Niagara issued his orders, and steered the ship to victory.  Within a few short months, Perry had assembled a fleet, gave the United States control of Lake Erie, the upper lakes, all adjacent territory, and guaranteed to the United States its freedom of movement on these vital waterways.  Through Perry’s efforts, the United States also laid claim to the Northwest Territory.

Commodore Joshua Barney distinguished himself during the War of 1812, as well.  See also: The Intrepid Commodore.

In the defense of New Orleans, Commodore Daniel T. Patterson demonstrated keen insight and raw courage against attacking British ships.  Patterson correctly predicted that the British would assault New Orleans rather than Mobile and further, that their advance would be along the shortest route, through Lake Borgne and Lake Ponchartrain.  He deployed a riverine force of five gunboats, two tenders, and his two largest ships as a means of forcing the British to delay their arrival in New Orleans.  In doing so, he gave General Andrew Jackson time to complete his defensive works in Chalmette.  See also: At Chalmette, 1815.

The shoreline of the modern United States is 12,383 miles.  Even in America’s early days, the US shoreline was a considerable distance to protect and control.  Before and after the War of 1812, buccaneers, filibusters, and other intruders plagued the United States.  Using longboats, the Navy hunted down pirates through coastal estuaries, Caribbean inlets and lagoons, or waging guerrilla war against hostile Indians.  Their mission took sailors and Marines into the dank and dangerous swamps and bayous of Georgia, Florida, Alabama, Mississippi, and Louisiana.  Whether employing large ships, ironclads, tin cans, rafts, or canoes, the Navy proved time and again that it had flexibility and adaptability in riverine operations, which has become part of the Navy’s proud heritage. 

The Pirates

Pirates had long infested the Caribbean and Gulf of Mexico, fueled in no small measure by the rapid growth of American commerce.  In the early 1820s, pirates attacked merchant ships nearly 3,000 times.  The associated financial losses were staggering; murder, arson, and torture were commonly inflicted upon American seamen.  Commodore James Biddle, USN, took on the pirates, filibusters, and free-booters.  In command of the West Indies Squadron, Biddle mounted raids in open longboats, manned by sailors for days at a time in burning sun or raging storm.  He reached into uncharted bays, inlets, and small but treacherous rivers—to locate, close with, and destroy the buccaneer menace.

Biddle utilized his heavy ships as the backbone of his riverine force and as sea-going bases for smaller craft.  This strategy steadily reduced piracy through such stellar efforts of Lieutenant James Ramage, USN and Lieutenant McKeever, who commanded the Navy’s first steamship to see combat action on the high seas, USS Sea Gull.  McKeever levelled the pirate base at Matanzas, Cuba in April 1825.  When buccaneers realized that their occupation was becoming less profitable and increasingly hazardous, they started looking around for other work.

Swamp Wars

Between 1836-42, Seminole and Creek Indian wars in the Florida Everglades produced a conflict uncannily like that waged in Southeast Asia 125 years later.  In 1830[1], the US Congress passed the Indian Removal Act to remove Florida tribes to reservation lands west of the Mississippi River.  Shockingly, many of these Indians refused to cooperate with the Congress.  Unsurprisingly, a band of Seminoles attacked and massacred a US Army detachment under the command of Major Francis Dade.  The event occurred in Tampa in December 1835.  Almost immediately, the US government moved more soldiers into Florida and Commodore A. J. Dallas’ West Indies Squadron landed parties of Marines and seamen to add weight to the military presence there.

The frustration of fighting a shadowy enemy who was completely at home in the swampy wilderness and rivers in West Florida prompted the Army to ask for naval assistance delivering supplies, establishing communications, and mounting operations along the Chattahoochee River.  One of the first naval units assigned was led by Passed Midshipman[2] J. T. McLaughlin.  In addition to his duties, McLaughlin served as Aide-de-Camp to Lieutenant Colonel A. C. W. Fanning.  McLaughlin was seriously wounded by Indians at Fort Mellon in February 1837.

As the pace of war quickened, the Navy’s riverine force grew.  The Navy purchased three small schooners in 1839, which operated in the coastal inlets to chart the water, harass the Indians, and protect civilian settlements.  In addition, McLaughlin, then a lieutenant, commanded many flat-bottomed boats, plantation canoes, and sharp-ended bateaux which he used to penetrate the Everglade Swamps.  In effect, McLaughlin commanded the “mosquito fleet,” a mixture of vessels manned by around 600 sailors, soldiers, and Marines.
