Commandant Henderson is credited with thwarting President Jackson's attempts to combine and integrate the Marine Corps with the Army. Instead, Congress passed the Act for the Better Organization of the Marine Corps in 1834, stipulating that the Corps was part of the Department of the Navy as a sister service to the Navy. This would be the first of many times that the independent existence of the Corps was challenged.

Document 10: Canadian Armed Forces: The responsibility for military command remained with the British Crown-in-Council, with a commander-in-chief for North America stationed at Halifax until the final withdrawal of British Army and Royal Navy units from that city in 1906. Thereafter, the Royal Canadian Navy was formed, and, with the advent of military aviation, the Royal Canadian Air Force. These forces were organised under the Department of Militia and Defence, and split into the Permanent and Non-Permanent Active Militias—frequently shortened to simply The Militia. By 1923, the department was merged into the Department of National Defence, but land forces in Canada were not referred to as the Canadian Army until November 1940.
