Benteen's and Reno's defense said that a few wounded soldiers of Reno's command forbid 400 men to leave the safe place of Reno Hill and support Custer's 210 men under fire. Godfrey disagreed:

“I thought General Custer was below us and we could join him that we had no water and a few wounded; that we would have our casualties and burdens increased on the morrow.”
