I wonder if there's a movie being made about him...

From what I can gather he could do amazing things on a horse and the only reason he went along with plans to go to West Point was so he could join the cavalry. Some of the action sequences on horseback... I see Grant being shot/portrayed like he's the main character in an Assassin's Creed game.

Grant didn't graduate high enough in his class to be assigned to a cavalry unit like he wanted.

One of the things that's fascinating to me about Grant is all of the setbacks he's had in his life and how he worked through them in practical and humble ways.
