The increase of over 400,000 in the naval personnel came partly through expansion in the permanent strength of the navy, partly through the enlargement of the various naval reserves, fleet, auxiliary, coast defense and others, and to some extent through the national naval volunteers and the Marine and Hospital Corps. In September, 1918, provision was made by which men in the selective service might enter the navy instead of the army. A quota of 15,000 men a month was allotted to the naval service, and 5,000 monthly to the Marine Corps for four months, after which its monthly quota was to have been 1,500. Provision for the navy was made, at the end of September, in the Students’ Army Training Corps, under instruction in several hundred colleges, and naval sections were established in ninety of these institutions and placed under the instruction of naval officers. But the sudden close of the war in November made unnecessary the completion of these plans for the further expansion of the navy. While increasing its size and strength at the swift pace that marked all our war preparations, at the same time it met every need for its services, of whatever sort, with promptness and efficiency. That had meant zealous and incessant work in the education for their new duties of more than 300,000 young men who had joined the Naval Reserve Force, in addition to those who had become a part of the naval forces in other ways. At a number of immense camps, where were built barracks, lecture halls and other necessary buildings for the housing and training of from 20,000 to 40,000 students at each station, the young men were trained in naval discipline and schooled in the maritime and naval subjects in which they must be proficient. Special schools for officers gave to those who were qualified and ambitious the necessary instruction. Other schools for advanced and specialized work trained officers for submarine duty, for assignment to the naval torpedo station and for work as naval aviation and naval turbine-engine engineers. An intensive course of instruction at Annapolis Naval Academy completed the training for officer duty for many who had already had sea service.
