Rare ALS from Captain Charles Varnum of the 7th Cavalry, Chief of Scouts at the Little Big Horn under Custer.  Dated 12/14/78 from Fort Abraham Lincoln where the 7th Cavalry started out on its ill fated rendevouz with history.   To his brother, about half is about family business, then he goes on to talk about how he is Regimental QM for the 7th now, how he is remodeling the Fort QM office and making things run more smoothly, weather is atrocious, talks about keeping 132 head of cattle alive in the winter and more.  Full Transcription available.  His letters have been known to sell for thousands at auction being relatively rare.    "Charles Albert Varnum (June 21, 1849 – February 26, 1936) was a career United States Army officer. He was most noted as the commander of the scouts for George Armstrong Custer in the Little Bighorn Campaign (of which he was the last of the surviving officers to die of natural causes) during the Great Sioux War, as well as receiving the Medal of Honor for his actions in a conflict at Drexel Mission following the Wounded Knee Massacre."  Bold signature as QM.
