The Battle of Crampton's Gap, or Battle of Burkittsville, was a battle fought between forces under Confederate Brig. Gen. Howell Cobb and Union Maj. Gen. William B. Franklin as part of the Battle of South Mountain on September 14, 1862, at Crampton's Gap in Western Maryland, during the Maryland Campaign of the American Civil War. Franklin's VI Corps attacked a small, hastily assembled Confederate force at Crampton's Gap in South Mountain that sought to protect the rear of Confederate Maj. Gen. Lafayette McLaws, who was across Pleasant Valley on Maryland Heights taking part in the siege of Harpers Ferry. Despite inferior numbers, the Confederate force held out throughout the day, taking heavy casualties. By the evening the VI Corps broke the Confederate line and proceeded through the gap into Pleasant Valley. Franklin, however, failed to follow up on his success and did not attack McLaws on Maryland Heights. Tactically the battle resulted in a Union victory because they broke the Confederate line and drove through the gap. Strategically, the Confederates were successful in stalling the Union advance and were able to protect McLaws' rear.
