The last three paintings (figs. 8-10) fall in the period of Stieffel's service at Fort Keogh in the Department of Dakota. The fort, named for Captain Miles Keogh (who died with Custer in the Little Big Horn massacre) and originally called Cantonment Tongue River, was located at the confluence of the Tongue and Yellowstone Rivers near present-day Miles City, Montana. The pictures of both the fort (fig. 8) and Miles City (fig. 9) are subject to check against extant photographs; they are amazing in their detail and accuracy. The over-all layout of the fort conforms, and such minute details as the gable windows and chimneys of the officers' quarters on the left of the parade ground and the two-story verandas on the enlisted barracks opposite are absolutely correct.[36] The familiar stables, corral, wood piles, and hay piles--the latter surrounded by a stone wall as protection against grass fire in the dry months--are readily discernible (fig. 8). The low stone buildings and corral in the right centerground probably are part of the original structures of Cantonment Tongue River. The small shacks to the left of them probably are the homes of the civilian hangers-on who founded Miles City in 1876 after being ejected from the post by Col. Nelson Miles, the commander of the 5th Infantry. The first site of Miles City can be seen in the upper right corner on the banks of the Tongue. The town was moved across the river in 1877. The mounted drill in the foreground is difficult to explain in a period when and in an area where the troops were almost constantly in the field under combat conditions. Perhaps it is mere window dressing by the artist. It is entirely possible, however, that Stieffel has pictured elements of his own regiment, which was mounted from 1877 until after the surrender of Sitting Bull in 1881. Being basically infantry they would be most in need of training in mounted tactics. Then again, these could be legitimate cavalry whose commander thought had wandered too far from regulation movements during the unorthodox winter warfare they had been waging against the Indians.
