I'm a details man when it come to military history, so I apologize if it seems the ACW has been covered in several other topics. I find the history of our own Civil War to be fascinating in many aspects and I would like to discuss it further in a dedicated thread.
More specifically:
1. Union General has mentioned that the Henry Rifle is the manliest of Civil War rifles. I couldn't disagree, the Henry was badass. But it was hardly prolific. The ACW was the only time in our history that we had such variation in individual shoulder arms on the battlefield. Coming from the 21st Century, this is amazing to me as everything in most modern militaries is so standardized. Supply must have been a nightmare in the ACW, I don't know how they did it. In the early war, Confederate volunteers not infrequently showed up to muster with flintlock muskets. This would be like me showing up for deployment training now with a Winchester or an early 20th Century bolt-action rifle. Plus, so many of our shoulder arms were supplied by the UK or Europe. Interesting that they didn't take a more active role in our war.
2. The Union had the decided advantage in artillery throughout the war. The most common pieces being the Napoleon 12-pounder and the 3-Inch Ordinance Rifle. The Confederacy relied heavily on captured field guns, which also blows my mind as this must have created a major headache for supply and training. That being said, my favorite artillerist of the war was ironically E. P. Alexander, a Confederate. Talk about making the most of what you have, Alexander was a forward-thinking officer and deserves more credit than history has afforded him.
3. Europe saw the U.S. as a backwater state and our war as a backwater affair. It's a shame, because it was a very modern war in many regards and Europe could have learned a lot of lessons from it if they'd bothered to study it. This isn't an argument about the "first modern war," there are cases to be made for several wars to claim this title. But the ACW was at the cusp of the modern era of warfare regardless.
4. Lee. So much has been said about Lee, I don't know where to go with this. Lee's involvement kept the war going probably three years longer than it would have if he'd not sided with the Confederates. Hell, if he'd come with us the war might have only lasted six months like everyone predicted. But who knows? Anyway, Lee always said his first loyalty was Virginia so it is probably an irrelevant question. I will say that Lee's decision to launch Pickett's Charge at Gettysburg cost him that battle and what remained of the Confederate initiative. Did it cost the South the war? Let me know what you think...
5. The ACW is among the most important events concerning the formation of our current Union (yes, we are all now Union as we won the war

). As important, if not more so, than:
A. The Declaration of Independence
B. The Ratification of our Constitution
C. Manifest Destiny
D. The Monroe Doctrine
These are a few things I like to discuss. Feel free to talk about whatever you want regarding the ACW, from field rations of the typical soldier to the Abolition of Slavery.
