Their faces and hands blackened by smoke and their ears ringing from constant musketry, Starkweather’s shattered brigade retreated to the ridge and saved half of their cannon by dragging them back to new positions, even as their commander, General Terrill, was fatally struck by a shell there. Union infantry took cover behind a stone wall on the distant hill, where Perryville’s rolling terrain allowed the Federals to form another defensive position. Maney’s Confederates regrouped and rushed through the valley, fighting desperately at the wall and assaulting it again and again until a Union counterattack forced Maney’s exhausted, ammunition-short brigade to retreat behind the hill. Neither side renewed the struggle afterward: Maney’s brigade fell back to Parsons’ Ridge, and Starkweather’s troops retreated west. Although Maney’s attack helped the Confederates secure a tactical victory at Perryville, Starkweather’s stand saved a third of the Union army. Bloodied in victory, with some units losing more than half their command, the Confederate Army soon marched out of Kentucky and never returned in strength. The 4th Indiana Battery under Captain Asahel K. Bush lost 13 men and 35 horses while defending Starkweather’s Hill.
