Under this discretionary power, the Army was reorganized into the Legion of the United States. This was a field army in which the three combat branches--infantry, cavalry, and artillery--were combined. The Legion was in turn broken down into four sublegions, with each containing infantry, cavalry, artillery, and riflemen; thus, the sublegions were the fore-runners of the modern combined arms team. The 1st and 2d Infantries became the 1st and 2d Sublegions. Of the three additional infantry regiments authorized, only two were organized, these becoming the 3d and 4th Sublegions.[8] Under the forceful leadership of Gen. Anthony Wayne the Legion reversed the record on the frontier and decisively defeated the Indians at the Battle of Fallen Timbers. The temporary peace which followed turned attention to the problem of protecting the Atlantic seaboard, and in 1794 Congress authorized a large increase in the artillery, assigned engineer officers, and designated the new organization the Corps of Artillerists and Engineers.[9] The Legion was continued until it was replaced in 1796 by the 1st, 2d, 3d, and 4th Infantry Regiments, which were constituted from the four sublegions, two troops of light dragoons, and the above-mentioned Corps.[10] [Footnote 8: _American State Papers_, pp. 40-41.] [Footnote 9: Act of May 9, 1794 (_Military Laws_, p. 104).] [Footnote 10: Act of May 30, 1796 (_Military Laws_, p. 114).] The threat of war with France in 1798 brought further expansions. In April of that year an "additional regiment" of artillerists and engineers was authorized, with the Corps created in 1794 becoming the 1st and the new unit being designated the 2d Regiment of Artillerists and Engineers.[11] In the following July, 12 more regiments of infantry and 6 troops of light dragoons--to be combined with the two troops in existence to form a regiment--were authorized; an additional 24 regiments of infantry, plus units of other arms, authorized the following winter made a total of 40 regiments of infantry.[12] Actually, the greatest part of this force remained on paper. Only the 1st and 2d Infantries ever attained their required strength, and only 3,400 men were enlisted for the 5th through the 16th. There were no enlistments at all for the other regiments. Officers were assigned to the six troops of light dragoons, but no enlisted personnel were raised and no horses were bought.[13] [Footnote 11: Act of April 27, 1798 (_Military Laws_, pp. 119-120).] [Footnote 12: Acts of July 16, 1798, and March 2, 1799 (_Military Laws_, pp. 127-128).] [Footnote 13: _American State Papers_, p. 137.]
