● The northern army led by George McClellan and the southern army led by Robert E. Lee met at Antietam Creek, Maryland in September, 1862. It was a bloody battle where 13,000 Confederates and 12,000 Union troops died in just one day. McClellan had hesitated to attack before the battle thus letting the southern troops regroup. Also, he had saved reserves and refused to use them at the end of the battle thinking that Lee was holding reserves for a counterattack, even though those reserves didn't exist. The Union victory stopped Lee's northward advance and was a turning point in the war.
