I've been wondering for sometime if anyone has any pic accounts or descriptions of Confederate or Federal officers and troops carrying Napoleonic swords and sabers. I have found a few instances, and it seems one of the most prevalent is the "Blucher" m-1796 heavy Cavalry saber. A very deadly weapon. Espeacially if you've ever seen the dude swinging this on Youtube.

One at the Mansfield State museum in Louisiana looks to be a French ANXI, Cavalry trooper's sword with black painted scabbard, but could be a German variation.
Here is a link to a Louisiana cavalryman wielding a m-1796 "Blucher" sword, but it is hard to see. The 1/2 plate ambrotype was sold at a New Orleans auction house.
