The Battle of Antietam: A Turning Point in the Civil War. Four days after the battle of Antietam, which took place near Sharpsburg, Maryland, on September 17, 1862, Captain Robert Gould Shaw of the 2nd Massachusetts Volunteer Infantry wrote to his father: âEvery battle makes me wish more and more that the war was over.
The battle shifted to the third and final phase, next to the waters of Antietam Creek. Nearby, a stone bridge crosses the creek, and on the other side, there's a steep bluff, 100 feet straight up.
