The Wagluhe at Ft. Laramie heard of the 50,000 casualties of the three-day Battle at Gettysburg in July 1863, and knew what white men meant when they spoke of battle. The Wagluhe observed and learned the customs of the whites. Wagluhe were considered by the U.S. Army and Indian agents to be the most progressive band of Lakota and many became Indian Police, U.S. Army Indian Scouts with the U.S. 4th Cavalry Regiment and intermediaries with other bands of Lakotas. The Wagluhe formed a civil administration at Ft. Laramie and Old Chief Smoke appointed Chief Blue Horse and Chief Big Mouth the first Indian Police officers. The U.S. Army concluded that, even if there were doubts about their reliability, the Wagluhe's role as scouts, civil administrators and mediators was absolutely essential. The Wagluhe were the first Oglala Lakota to send their children to the Carlisle Indian Industrial School in Carlisle, Pennsylvania, for a formal education, and the first to go Wild Westing with Col. "Buffalo Bill" Cody and his Wild West.
