[Footnote 18: Act of January 1813 (_Military Laws_, pp. 238-240). There is some confusion as to just how many infantry regiments were organized and actually came into being. The Act of January 29, 1813, authorized the President to raise such regiments of infantry as he should see fit, "not exceeding twenty." It seems that 19 were actually formed, made up partly of 1-year men and partly of 5-year men. There are 46 regiments listed in the Army Register for January 1, 1815, and it is known that several volunteer regiments were designated as units of the Regular Establishment and that a 47th and a 48th were redesignated as lower numbered units when several regiments were consolidated because of low recruitment rate. Mahon (in "History of the Organization of the United States Infantry") is not clear on this point. There is an organizational chart of the Army for this period in the files of the Office of the Chief of Military History, Department of the Army.] [Footnote 19: Act of February 10, 1814 (_Military Laws_, pp. 251-252).] In March 1814 Congress reorganized both the artillery and the dragoons. The three artillery regiments, which had never operated as such, but rather by company or detachment, were consolidated into the Corps of Artillery; and the two regiments of dragoons, which had never been adequately trained and generally had given a poor account of themselves, were merged into one.[20] The Regiment of Light Artillery remained untouched. [Footnote 20: Act of March 30, 1814 (_Military Laws_, pp. 252-255); JONES, p. 58; "History of the Organization of the United States Cavalry."] Almost as soon as the war ended, Congress moved to reduce the Army[21] by limiting the peacetime establishment to 10,000 men, to be divided among infantry, artillery, and riflemen, plus the Corps of Engineers. The number of wartime infantry units was reduced to eight, and the rifle units to one. The Corps of Artillery and the Regiment of Light Artillery were retained, but dragoons were eliminated.[22] [Footnote 21: Act of March 3, 1815 (_Military Laws_, pp. 266-267).] [Footnote 22: The reorganization of 1815 is treated by MAHON "History of the Organization of the United States Infantry" (pp. 11-12), JONES "History of the Organization of the United States Field Artillery" (pp. 59-60), and WIKE, unpublished study.] By 1821 the prospects of a prolonged peace appeared so good that Congress felt safe in further reducing the Army. Consequently, in that year the number of infantry regiments was cut to seven; the Rifle Regiment was disbanded; the Corps of Artillery and the Regiment of Light Artillery were disbanded, with four artillery regiments being organized in their stead; and the Ordnance Department was merged with the artillery,[23] an arrangement that continued until 1832.
