I was familiar with the image, but putting an ID on it took a while. Everybody and their uncles, here and in Yurrup were dreaming up stuff in that era for all the wars that kept popping up.
Burnside's other "invention" had a much bigger impact.
Anyone want to take a stab at the B.C. on that bullet?
What else did Burnside do of note, other than grow facial hair?
He failed as an Army Commander at Fredericksburg.and had a pretty mediocre record everywhere else. Why he was retained in any capacity speaks to how poorly the Union Army was led/managed.
