Michigan at Perryville
Among the 61,000 Union soldiers who at the Battle of Perryville ended Confederate attempts to gain control of Kentucky were six Michigan units. The most heavily engaged of these were Coldwater's Loomis Battery (Battery A of the First Michigan Light Artillery), the Second Michigan Cavalry and the Twenty-first Michigan Infantry. During the course of the battle, Battery A equipped with six ten-pounder Parrott guns, prevented the right flank of General Daniel McCook's corps from being turned and aided in the repulse of General Patrick Cleburne's Rebel brigade. At one point, Loomis was ordered to spike his guns and leave them. By refusing, he retained a key position. Battery A is reported to have fired the first and last artillery rounds of the battle.
