Thousands of men rallied to Sitting Bull. In the spring of 1876, Indians from almost every Sioux band, including the Santees and the Yanktonais, gathered with Sitting Bull in the Rosebud River valley and named him the leader of their campaign. It was the largest camp of Indians the Sioux had ever known; participants estimated that there were 1,400 lodges, plus individual men sleeping on their own or as guests in the tepees.
