A nice early CDV of Confederate General P.G.T. Beauregard. He was responsible for firing on Fort Sumter and 1st Bull Run. This is a very nice full standing CDV of a Confederate general. The backmark is a Boston backmark.
This cdv is titled "Bastion Opposite Battery No.2 of General McClellan's Works - Brady's Album Gallery, No. 392". You can see the Yorktown entrenchments, a Union soldier, sandbags, and a cannon and limber in the background.
