The story of the Fourth Marine Regiment
A provisional military unit or organization is formed on an ad hoc basis for specific operations and, at the time of its creation, is never intended to become a permanent command. The Marine Corps has had several provisional organizations in the past, and in the sense of its present-day operations, continues to do this as part of the Marine-Air-Ground Task Forces (MAGTFs). A MAGTF is an expeditionary organization formed with a specific mission or range of similar contingency operations . The more complicated the mission, the larger the MAGTF. At the conclusion of the assigned mission, ground, air, and combat support elements are returned to their parent (major) commands of the U. S. Marine Corps (e.g., divisions, wings, logistics commands).
In the Marine Corps, an infantry division provides necessary forces for amphibious assaults or in the execution of other operations as may be directed by competent authority. A Marine Division must be able to provide ground amphibious forcible-entry capability to an amphibious task force and conduct subsequent land operations in any operational environment. As the ground combat element of a Marine Expeditionary Force, the Marine Division may be tasked to provide task-organized forces for smaller operations.
There are three infantry regiments within a Marine Corps infantry division. The primary mission of an infantry regiment is to locate, close with, and destroy the enemy by fire and maneuver, or to repel his assault by fire and close combat. The infantry regiment consists of a headquarters company and two (or more) infantry battalions—normally, three such battalions. Infantry battalions are the basic tactical unit with which the regiment accomplishes its mission. The Marine Infantry Regiment is the major element of close combat power of the Marine Division. Infantry regiments (with appropriate attachments) are capable of sustained, independent operations. When the regiment is combined with other combat support and combat service support elements, it will form a Regimental Landing Team (RLT). The Fourth Marine Regiment is one of these.
The 4th Marines was initially activated in April 1911 to perform expedition duty. Later re-designated a Provisional Battalion, the organization was deactivated in July of that same year.
Diplomatic relations between Mexico and the United States were strained beginning in 1910, when a series of revolutions, counter-revolutions, civil conflict, and outright banditry resulted in several incursions by Mexicans into US territory, notably in Texas, New Mexico, and Arizona. This was a period during which Texas sent companies of Texas Rangers into the Rio Grande Valley to protect ranches and homesteads from Mexican depredations.
In April 1914, a number of American sailors were on liberty in Tampico, Mexico from USS Dolphinwhen they were arrested by Mexican authorities. We do not know why they were arrested, but having observed sailors on liberty in foreign ports, I have my own theory. The Mexicans soon released the sailors and issued an apology for the arrest. An outraged Rear Admiral Henry T. Mayo demanded that Mexican authorities render honors to the United States flag as Dolphindeparted port —this they refused to do.
Eleven days later, the United States learned that a German vessel was about to off-load a quantity of arms and munitions at Vera Cruz, Mexico. This was a violation of an embargo against the shipment of arms to Mexico, imposed by the United States because (1) the United States failed to recognize the legitimacy of the regime of General Victoriano Huerta, and (2) the bloodshed and turmoil associated with the Mexican civil wars/revolution. Mexico’s violation of the embargo gave President Wilson the excuse he needed to intervene. On 21 April 1914, Wilson ordered the Navy to land the Marines and seize the customs house at Vera Cruz.
One consequence of Wilson’s directive was the re-activation of the 4th Marines at Puget Sound, Washington.
The newly re-formed 4th Marines was initially composed of its headquarters company and the 24th, 26th, and 27th rifle companies. Colonel Joseph H. Pendleton, with considerable experience commanding expeditionary units, was ordered to assume command of the regiment. Within only two days, the regiment embarked aboard USS South Dakota and sailed for San Francisco, California. At Mare Island, four additional companies joined the regiment: the 31st and 32nd companies boarded South Dakota, and the 34th and 35th companies embarked aboard USS Jupiter. Both ships set sail almost immediately after loading the Marines.
On that same day, 21 April, USS Prairie landed 502 Marines in Vera Cruz from the 2nd Advanced Base Regiment. Marine Detachments and 295 sailors (bluejackets) from USS Florida and USS Utah also went ashore as a provisional battalion. The Mexican commander at Vera Cruz was General Gustavo Maass who, owing to a great deal of common sense, withdrew his forces from the city. The American landing force was unopposed but taking control of the city was not as easy. Fierce fighting began when cadets of the Vera Cruz Naval Academy, supported by fifty-or-so Mexican soldiers and untrained citizens resisted the US invasion force. Naval artillery destroyed the Naval Academy and its cadets. Afterward, the Marines took complete control of the city with little difficulty.
South Dakota and Jupiter arrived at Mazatlán on 28 April 1914, with South Dakota ordered to proceed further south into Acapulco harbor. Within a week, USS West Virginia arrived at Mazatlán with reinforcements, the 28th and 36th rifle companies. The 4th Marines was now comprised of ten rifle companies (three battalions) and all of its forces were in Mexican waters primed for action while stationary off the West Coast of Mexico.
The naval force remained in Mexican waters through June 1914. The 4th Marines would only be put ashore if the situation demanded it. By the end of June, Wilson had decided to support his own dictator of choice and with the election of Venustiano Carranza, tensions between Mexico and the United States eased. Wilson permitted the supply of arms and munitions to Carranza; the 4th Marines were withdrawn from Mexican waters.
Upon return to the United States, most of the regiment established its base of operations at San Diego, California; 1st Battalion (Major John T. Myers, Commanding) was (initially) ordered to return to Mare Island. The 1st Battalion later relocated to San Francisco, where a “model camp” was established on the grounds of the Panama-Pacific Exposition . Meanwhile, regimental headquarters and four rifle companies occupied a new camp on North Island. Owing to the success of the 1st Battalion’s model camp in San Francisco, Colonel Pendleton was tasked to do the same at the Panama-California Exposition in San Diego. The 2nd Battalion, operating under the command of Major William N. McKelvy  was designated to assume this assignment.
Then, in 1915, marauding Indians threatened the lives and property of Americans living in the Mexican state of Sonora. As Mexico had not taken any worthwhile measures to prevent these attacks, or to defend the Americans, relations between the US and Mexico were once more strained. USS Colorado was dispatched with BLT 2/4(-) , arriving off Guaymas on 20 June. Again, the Marines were withheld from going ashore.
In November 1915, Mexican revolutionaries and Yaqui Indian depredations prompted the dispatch of Marines to Mexico, this time involving the regimental headquarters and BLT 1/4 reinforced by the 25thand 28thcompanies. USS San Diego anchored off shore adjacent to Topolobampo, which exerted pressure on Mexican authorities to act in ending threats to American lives and property. Again, the Marines did not execute a landing in Mexico.
In the spring of 1916, civil war broke out in the Dominican Republic. Once more, by presidential order, Marines were ordered to intervene. See Also: Dominican Operations (in three parts). The regiment remained in the Dominican Republic until August 1924.
After returning to San Diego, California, the 4th Marines began receiving Marines from a recently deactivated 7th Marine Regiment. With so many years of peace keeping and constabulary duties in the Dominican Republic and the arrival of new personnel, the regiment began a series of training operations to reorient the Marines to their intended purpose: landing force operations, which have always been a complex undertaking. Training included maneuvers in the Hawaiian Islands. Normal peace time operations were interrupted in 1925 when 2/4 was dispatched to aid local authorities in Santa Barbara, California. An earthquake had severely damaged the city. Duty for these Marines involved general assistance to the civil government and for augmenting law enforcement agencies in restoring order, guarding property, and preventing looting.
In October 1925, the 4th Marines was reorganized to include a third rifle battalion, but for whatever reason this battalion was deactivated within nine months. In 1926, following a series of mail robberies, the President ordered the Secretary of the Navy to assign Marines to mail protection duties. The United States was divided into two zones of operations. Brigadier General Smedley D. Butler was placed in overall charge of the western operations and the 4th Marines became America’s mail guards. Units of the 4th Marines were deployed throughout the western states. Their mission not only included guarding trains and postal trucks, but also post-office guards and railway stations. See also: General Order Number One. Not even the American mob wanted to tangle with Marines; by 1927, the number of mail robberies had dropped to nearly zero and, as the postal department had created its own system of armed guards, the 4th Marines were sent back to San Diego, California.
Our world is not now and has never been free of conflict. In early 1927, threats to the security of the International Settlement in Shanghai, China sent the 4th Marines to deal with the problem. The 4th Marine Regiment subsequently spent so much of its time in China that they became known throughout the Corps as “The China Marines.” Of the number of Marine officers assigned to China with the 4th Marines, six went on to serve as Commandant of the Marine Corps: Alexander A. Vandegrift, Clifton B. Cates, Lemuel C. Shepherd, Jr., Randolph M. Pate, David M. Shoup, and Wallace M. Green. See also: The China Marines (series).
Tensions within the International Settlement in Shanghai never quite subsided, particularly since the Japanese adopted an aggressive stance in China. See also: Pete Ellis-Oracle. With a large contingent of Japanese forces located on the outside of Shanghai, their command authority embarked on a systematic program to undermine the position of the Western powers in the International Settlement. It then became the mission of the Marines to thwart any Japanese attempt to change the status quo of the American sector. The reality of the situation, however, was that should the Japanese have made an overt attempt to seize the American sector, the Marines would receive no assistance from other foreign military contingents. The atmosphere in China after the outbreak of the European war in 1939 was tense; the future of China uncertain. Italy, at the time an official ally of Japan, placed no value in preserving the International Settlement. The situation worsened in 1940 when Italy became actively involved as an ally of Germany against Great Britain and France. It was a downward spiral: The Vichy government of France ordered French forces not to interfere with Japanese military intentions in Shanghai, whatever they might be. At this time, the only obstacle to Japanese aggression in the International Settlement was the 4th Marine Regiment.
In early 1941, Admiral Thomas C. Hart, Commander-in-Chief, Asiatic Fleet concluded that war with Japan was inevitable. Accordingly, on his own initiative, he began withdrawing his most exposed units. He recommended to President Roosevelt the withdrawal the 4th Marines, as well. Roosevelt still had not made his decision by September 1941; the situation had by then become dire. US intelligence sources uncovered evidence that Japan was planning to implement a series of incidents that would give them an excuse for seizing the American sector of the International Settlement. Roosevelt finally acted and ordered all naval personnel out of China —including, finally, the 4th Marines. Complete evacuation of the American sector was ordered on 10 November 1941.
On 27 November, Headquarters 4th Marines and the 1st Battalion embarked aboard SS President Madison. The rest of the regiment boarded SS President Harrison the next day: destination, Philippine Islands. The situation was serious enough to cause the navy to assign four US submarines to escort these contracted troop ships to the Philippines. Not so amazingly, the Japanese knew the full details of the Navy’s withdrawal operations, including the names of the ships and their destinations —even before either ship arrived in Chinese waters. One reminder to all hands during World War II was, “Loose lips, sinks ships.”
The unhappy story of the 4th Marines in the Philippine Islands is provided as part of a series titled On to Corregidor. As a result of this debacle, the regimental commander, Colonel Samuel L. Howard ordered the United States Flag and the Regimental Colors burned to avoid their capture by Japanese forces in the Philippines. At that moment, the 4th Marine Regiment ceased to exist. The date was 6 May 1942.
American Marines are a proud lot. There was no way on earth that Marine Corps leadership would allow the 4th Marines to pass into history. On 1 February 1944, the 4th Marine Regiment was reactivated, reconstituted from units of the 1st Raider Regiment. What the Marines needed more of at this stage of the Pacific war was infantry battalions, and fewer “special purpose” battalions. In any case, the reactivation of 4th Marines was unique in the sense that the lineage and honors of both the “old” 4th Marines and 1st Raider regiment were passed on to the “new” 4th Marine Regiment. The regiment’s first operation was the seizure of Emirau Island in the St. Mathias Group. America needed airfields, and since you can’t construct these with Japanese soldiers running all over the place, the Marines were send to terminate all Japanese forces with extreme prejudice. The Japanese, having anticipated that the Americans wanted this island withdrew some time before the landing. The 4th Marines first amphibious landing was unopposed. There was no need for these Marines to worry, though. Marine Corps leadership found something for them to do —they went to Guam. The Battle for Guam is presented in sections.
Next on the agenda for the 4thMarines was the Battle for Okinawa—a brutal slog-fest lasting from 1 April 1945 to 22 June 1945. In this awful battle, the 4thMarines would serve alongside the 15thMarines, 22ndMarines, and 29thMarines and part of the 6thMarine Division. That story will continue next week.

 Colonel McKelvy (1869-1933) received his commission as a Marine officer after graduating from the US Naval Academy in 1893. McKelvy served during the Spanish-American War and was awarded the Brevet Medal for extraordinary courage under fire during his service in Cuba, 1898.
