The Battle of Antietam (or Sharpsburg) on September 17, 1862, climaxed the first of Confederate Gen. Robert E. Lee's two attempts to carry the war into the North. About 40,000 Southerners were pitted against the 87,000-man Federal Army of the Potomac under Gen. George B. McClellan.

Richardson's division, also of Sumner's corps, sought to drive the Southerners back. Confusion and sheer exhaustion finally ended the battle here and in the northern part of the field
