On June 28, Marsh and several other men were fishing about a mile from the boat when a young Native American on horseback approached. “He wore an exceedingly dejected countenance,” one man later wrote. By signing and drawing on the ground, the tribesman managed to convey that there had been a battle but the men did not understand its outcome. In fact, the Native American was Curley, one of Lieutenant Colonel George Custer’s Crow scouts. Three days earlier, he had been the last man to see Custer and his 7th Cavalry battalion before they were wiped out during the Battle of the Little Big Horn.
The following day, Marsh received a dispatch from General Terry, who had found Custer’s destroyed battalion and the surviving soldiers of the 7th Cavalry. Terry ordered Marsh to prepare to evacuate the wounded soldiers. Slowed by the burden of carrying the wounded men, Terry’s force did not arrive until June 30. Grant immediately received the 54 wounded soldiers and sped downstream as quickly as possible. With the Far West draped in black and flying her flag at half-mast, Marsh delivered the wounded to Fort Abraham Lincoln near Bismarck, North Dakota, at 11:00 p.m. on July 5.
The fast and relatively comfortable transport of the wounded by steam power undoubtedly saved numerous lives. Yet, Marsh was also the bearer of bad news. From Fort Abraham Lincoln, General Terry’s report of the disaster was telegraphed all over the country. Soon the entire nation learned that General Custer and more than 200 men had been killed along the Little Big Horn River.
