On June 27, 1862, Confederate forces under A.P. Hill and Longstreet attacked Fitz John Porter's forces at Gaines' Mill, during the Peninsula campaign. Due to poor coordination of Southern commanders, Porter was able to hold his line long enough for McClellan to reposition his forces on the James River, while exacting severe casualties on Confederate forces.
