Why did the U.S. Army lose the battle of “Little Big Horn?”
Custer was a high spirited man and sometimes too much of a high spirit would mean he would not be able to think rationally, which also means he would push his men to the limit and make them exhausted and therefore unfit to fight, which can cause low morale. This may have been a factor in making his soldiers surrender.
Custer also had a tended to be ignorant, was known for stupidity and selfishness as he completely ignored his scouts and charged at the largest Indian collection in the West with an ammunition supply that was below par. He used a massive bonfire which was used to cook his favourite dawn fry-up which in turn, gave away the Americans position to the Indians. He also disobeyed orders and went up Ash Creek instead of going the long way round the Wolf Mountain, which meant he was putting his glory ahead of orders and the main goal of winning the battle. Even though he only had about 600 men he decided to divide his force into 3 after declining extra men and Gattling Guns, as he thought they would slow him down.
