A group of reenactors pays special attention to Captain George Ahl and his band of former confederate soldiers who formed the 1st Delaware Heavy Artillery. Captain Ahl obtained permission from the War Department to form a battery of Confederate prisoners who could prove they had been conscripted into the Confederate Army. Upon taking an oath of allegiance they were permitted to join the Federal Army. Volunteers have recreated Ahl's Battery at Fort Delaware State Park. They have assumed the identities of members of the battery. The reenactors give demonstrations of what life was like for the members of the 1st Delaware Heavy Artillery.
