Culp's Hill
When Knipe went on convalescent leave because of an old wound, McDougall became acting brigade commander. He commanded the brigade on the march of XII Corps north that began on June 13, 1863. His brigade served on Culp's Hill, except when it went to the left flank of the army late on July 2, 1863, to help stop the Confederate advance. When they returned to the right flank, McDougall's men almost collided with Confederate troops who had occupied part of Culp's Hill. Knipe returned to XII Corps after Gettysburg, and McDougall rejoined his regiment. He did file a report on his brigade's actions at Gettysburg.
