Outraged by news of the defeat, Washington urged Congress to raise an army capable of conducting a successful offense against the Native confederacy, which it did in March 1792establishing more Army regiments (the Legion of the United States), adding three-year enlistments, and increasing military pay. The following month the House of Representatives conducted investigative hearings into the debacle. This was the first special Congressional investigation under the federal Constitution. Afterward, Congress passed two Militia Acts: the first empowered the president to call out the militias of the several states; the second required that every free able-bodied white male citizen of the various states, between the ages of 18 and 45, enroll in the militia of the state in which they reside.
