George Armstrong Custer was no hero. He was a disgrace.
The Indians had already stopped and turned back the army advancing from the South.
Custer was with the Northern army. His force was sent out to find and locate the Indians.
Most of the officer thought the Unduabs would try to slip away - to save their families and possessions.
