A book on Halifax County, Virginia entitled "Yesterday - Gone Forever, A Collection of Articles" by Faye Royster Tuck, 2003, describes an event involving Richard Thomas Edwards of Company K, 14th Virginia Regiment. Edwards was captured near the rock fence during Pickett's charge at Gettysburg on 3 July 1863. Sent to prison, an order came to move some prisoners, including Edwards, from Fort Delaware to another site, and the men were making hurried preparations to cook breakfast before their departure. Edwards and his tent-mate (not identified) made a fire in the dim early light. Unbeknownst to them, someone apparently was trying to smuggle out a can of gunpowder and had secreted it in the ashes. The gunpowder exploded, seriously injuring Edwards and blinding him, while killing his tent-mate. Edwards was honorably discharged on 10 November 1864 and died in Halifax County in 1919. Is there independent confirmation of this story? I've not heard of a prisoner storing a cache of gunpowder, and wonder if it was part of an escape plan.
