The posse subsequently succeeds in putting down the rogue soldiers and destroy the munition dumps there.
Events of Red Dead Redemption 2
Eagle Flies is captured by the U.S. Army, and held at the fort. Charles, in the hopes of rescuing him, scouts out the fort and finds that there is a way in through the back. He leads Arthur across the river, so they aren't detected by the army. They wait until night when the patrols leave, before killing the guards in the front of the fort and sneaking to the back. It is then that they use ropes to get into the fort, and silently slay the guards on the walls. They then take the prison, and grab Eagle Flies. Arthur breaks a hole in the wall, and they fight their way to canoes, which they use to get as far away from the fort as possible.
