I always liked Custer after reading an account of a Civil War battle where he rode up to the command tent where the Generals were sitting around studying maps. The Union had won the upper hand in the battle and the Confederates were in full retreat. The Generals were hesitant and overcautious to follow up on the victory as Custer burst in screaming at them to keep fighting. They said something like they couldn’t find a place where the army could cross the river. Custer ran out jumped on his horse rode to the middle of the river outside the tent screaming and cursing at them saying right here is where we can cross. It was too late when they finally did realize he was right. I wish I was better on specifics but that scene always stuck with me.
It was Custers boldness that forced Lees surrender at Appomattox on April 9th.
There was a charge on cannons to take the baggage train.
Then they positioned a skirmish line over the line of retreat.
Some infantry was rushed up to help hold the line.
The Confederates made a token attack to try to break out... then after a pause, arranges the surrender ...
Lee gave Custer the desk that the surrender was signed on - because he was most responsible for the surrender.
That’s from memory, no go look up the official story.
