The first breaching gun goes in
The first emplacement for a heavy breaching gun — an 8-inch Parrott rifle — was finished on the left and the gun mounted, served from a bomb-proof magazine built expressly for it. It first fired at Fort Sumter on 12 August. That day Captain Chichester, whose company had been ordered out of Battery Wagner, asked permission to stay on at the battery anyway.
