“The casus belli was a lame cow! The Mormons, whose cow had been taken, complained at Fort Laramie, and a rash young officer, Lieutenant John Grattan, rode out [to the Sioux camp] with twenty-eight men and a small cannon.
The soldiers fired the canon and wounded two warriors. This was too much for a proud people, even though they had fallen to the point of scavenging on emigrants. The Sioux charged, and in a few minutes, Lieutenant Grattan had twenty-four arrows in him, and his men had been wiped out.
The fat was in the fire, but the Sioux were not yet capable of waging a real war. (They would learn. Before the story was over, Fetterman, Custer, and others would discover how well Sioux had learned!).”
