During the Quasi-War with France, Congress established in May 1798 a three-year “Provisional Army” of 10,000 men, consisting of twelve regiments of infantry and one regiment of cavalry to exist simultaneously with the United States Army. Although the commanding officer of the Provisional Army was George Washington, he accepted the appointment on the condition that he remain in retirement at Mount Vernon until he was actually needed. In March 1799, Congress created an “Eventual Army” of 30,000 men, which was to include the Provisional Army and three regiments of cavalry, but neither army was fully recruited or mobilized. Congress dissolved the Provisional Army in June 1800.
This letter to Major John Adlum of Pennsylvania was part of Major General Alexander Hamilton’s efforts as the ranking general below Washington to prepare forces for the brewing hostilities with France.
