Mentioned in several publications on the life and times of William F Cody we find the 1841 US Rifle in service of Teamsers
working for the US Quartermasters office. Young Buffalo Billy, as he was called by Wagonmaster Lew Simpson, tells
of his service as a cavallard driver on two trips to Utah in 1857. Cody states that all men were armed with Yagers and
Colt Revolvers. Cody dispatched a Sioux indian with his Yager on the first trip out. The second time, Cody, Simpson,
and George Wood were riding between trains and got suprised by a Sioux Party in greater numbers. Nowhere to run,
Simpson shot their mounts to use for breastwork and fight off the Sioux attacks until the rear train came up.
