Interesting. You read about history. LOL! Comes across a little different that way.
I'm no history expert, but that mirrors my understanding.
I really think that's part of the reason the Civil War was so bloody. America was on the cusp of the industrial revolution (at least the groundwork was being laid) and the weaponry had overtaken the battle tactics. Soldiers were still lining up in firing formation with bayonets fixed, but the weapons were much more accurate and devastating than they were just a few years before. Every engagement was a slaughter on both sides.
