In their service on battleships and cruisers, the marines form a part of the ship's complement for battle, manning the 6-inch, 5-inch, 3-inch, and 6-pounder guns of the intermediate and secondary batteries. They are trained and fully equipped for instant service as landing-parties for duty on shore.
Great mobility and facilities for quick action are required of the marines, and they must be kept in readiness to move at a moment's notice and be prepared for service in any climate. They have seen service in Egypt, Algiers, Tripoli, Mexico, China, Japan, Korea, Cuba, Porto Rico, Panama, Nicaragua, Santo Domingo, Formosa, Sumatra, Hawaii, Samoa, Guam, Alaska, and the Philippine Islands.
Lieutenant P. N. O'Bannon, of the Marine Corps, hoisted the first American flag ever flown over a fortress of the Old World when Derne, a Tripolitan stronghold, was taken by assault on April 27, 1805. The first regulars who entered the fortress of Chapultepec, in Mexico City, when it was taken by storm on September 13, 1847, were marines, under command of Major Levi Twigg. Under command of Robert E. Lee, later commanding the Confederate Army, marines captured John Brown at Harper's Ferry, in 1859. A battalion of marines under Captain John L. Broome, occupied New Orleans upon its surrender, and hoisted the American flag on the custom house, April 29, 1862. A battalion of marines, 646 officers and men, commanded by Lieutenant-Colonel R. W. Huntington, was the first American force that landed in Cuba in 1898, when it established a base for Admiral Sampson's fleet at Guantanamo, holding their position against Spanish regulars who were said to number 7,000.
The United States Marines of the battleship Oregon, Captain John T. Myers commanding, were the first American troops to enter Peking just before the Boxer insurrection broke out in 1900. Lieutenant-Colonel Neville's marines were the first ashore at Vera Cruz in April, 1914.
It will thus be seen that the Marine Corps of the navy is a highly useful organization, and that it has played a large part in carrying our flag to the fore in all our wars. Until 1883 officers in the corps were appointed from civil life. Beginning with that year, all vacancies were filled from graduates of the Naval Academy at Annapolis. This practice continued until 1898, when the increase in the corps was so rapid that the Academy could not furnish a sufficient number of officers. Since then, until 1915, appointments were made from civil life and by promotion from the ranks. In 1915 vacancies again began to be filled from Annapolis, but the entrance of our country into the war brought about the award of commissions on a broader scale. To-day, serving with the marines in France are a number of young officers who, a year or two ago, were well-known college athletes, such men as Eddie Mahan, of Harvard; Billy Moore, of Princeton; Harry LeGore, of Yale; Albert Baston, of Minnesota, and many other gridiron and diamond heroes, who were attracted to this branch of the service by the opportunities offered for quick action.
There is a Marine Officers' School at Norfolk, to which young men appointed second lieutenants from civil life are sent for two years' intensive study before being assigned to regular duty. The course covers general subjects, and also all military branches, such as engineering, topography, gunnery, electricity, signalling, torpedo operation, and the like. In the case of college men appointed lieutenants for war service, the majority had just been graduated or were seniors in their respective institutions; as a consequence, little time was lost in the study of general subjects, the idea being to concentrate upon military subjects. In short, the Plattsburg idea was put into effect, with what results may be judged by the words of high praise which have been said concerning the marine subalterns in France.
Since war began the corps has grown from a total of 13,266 enlisted men and 426 officers to a present strength of 38,629 enlisted men and 1,389 officers. The increase in enlisted men has been through voluntary enlistment; in one instance a college battalion enlisted as a whole. The personnel represents all classes of the community; college and business men, athletes, mechanics, laborers, and in one instance a former Congressman, who, although slightly over the usual age, attained the rank of second lieutenant through his devotion to duty and application.
The recruit depots at Port Royal, S.C., and Mare Island, Cal., have proved equal to the demands made upon them, and here the preliminary training of the mass of recruits has been accomplished. No detail of the training of a soldier has been neglected, and on the transfer of these new men to the concentration camp at Quantico, Va., the majority has worn the insignia of expert rifleman, sharpshooter, or marksman. Here at Quantico the men have completed their course of intensive training in the new organizations formed at that post for service overseas. Five regiments of infantry, with their attendant replacement units, have been organized in addition to a brigade of artillery, since the creation of this new post, in June, 1917.
Besides the brigade of marines in France, it is necessary to maintain forces of marines in Santo Domingo, Hayti, the Virgin Islands, Guam, Cuba, China, the Philippines, Porto Rico, and Honolulu, while there is a small detachment in London. The fleet of battleships and cruisers absorbs a goodly percentage of the present force, while at the same time it has been necessary to supply men to augment the garrisons of the navy-yards, naval ammunition depots, radio-stations, and other posts of the country.
