[40] Although no longer in Confederate hands, Corput's four 121-pound Napoleon Cannons[41] sat in a "no man's land" for the rest of the day until nightfall, when Union soldiers "dug through the parapet, slipped ropes around the four cannons, and dragged them back to [their] lines".[40]

Peachtree Creek
During the Battle of Peachtree Creek, on July 20, 1864, Harrison commanded his brigade against General W. S. Featherston's Mississippi Brigade, stopping the latter's "fierce assault" over Collier Road.[42] At Peachtree Creek, Harrison's brigade comprised the 102nd, 105th, and 129th Illinois Infantry Regiments, the 79th Ohio Infantry Regiment, and his 70th Indiana Regiment; his brigade deployed in about the center of the Union line, engaging Maj. Gen. William Wing Loring’s Mississippi division and Alabama troops from General Alexander Stewart's corps.[43] In his report after the battle Harrison wrote how "at one time during the fight," after his ammunition was dangerously depleted, he sent his acting assistant inspector-general Captain Scott and others to cut "cartridge-boxes from the rebel dead within our lines" and distribute them to his soldiers.
