In 1871, General of the Army William Tecumseh Sherman arrived at Fort Sill from Fort Richardson, Texas, while on a tour of Army posts throughout the country. Sherman was at Fort Richardson when they became aware of the Warren Wagon Train Raid, in which seven muleskinners were killed by Indians when their wagon train was ambushed. Soon after Sherman arrived at Fort Sill, the Indian Agent brought several Kiowa chiefs to tell their story about attacking the wagon train. When Sherman ordered their arrest during a meeting on Grierson's porch, two of the Indians attempted to assassinate him. In memory of the event, the Commanding General's quarters were dubbed Sherman House.
