In fourteen days of fighting in June 1864 at Kennesaw Mountain, more than 3,000 Union and 1,000 Confederate soldiers were killed or wounded, and although the losses were severe, Union troops continued pushing southward by advancing, outflanking, and advancing again up and around the mountain. First Sergeant Walter Clark of the 63rd Georgia Infantry wrote of the grim and silent place and of shadows on soldiers' hearts and on hearts and hearthstones far away, shadows that still rest there and never will be lifted; he survived, but thousands of others did not. Since 1935, the blood-soaked earthworks and battle sites have been preserved as Kennesaw Mountain National Battlefield Park, where peaceful fields and quiet woods still hold the memory of fallen soldiers, whose losses and sacrifices endure. Private George W. Warner of Company B, 20th Connecticut Infantry Regiment is pictured, and Harvey, the four-legged mascot of the 104th Ohio Volunteer Infantry, was also wounded in the war but survived along with his owner, Captain Daniel M. Stearns; many Civil War soldiers survived grievous battlefield wounds at a time when medical science had little to offer except amputation with a hand-powered saw.
