Forrest thought the shotgun was the best weapon for a cavalryman. Most historians like to compare Stuart to Custer due to the flamboyance factor both had and bizarre fashion statements they made.
I personally believe Judson Kilpatrick made much more of an impression on him than most realize. Neither one could care a less about the casualties they incurred.
Forrest seems to get the most of what he had available. He was audious when he had to be and cautious when necessary.
Didn’t know his view on shotguns.
