There are many unusual or unexpected records in the U.S. National Archives that shed light on the life on someone’s ancestor or relative. Among these is a slim volume in which were recorded the buyers and sale price of surplus military horses sold at auction on 12 February 1864 at Frederick, Maryland, and on 19 and 22 February 1864 at Reading, Pennsylvania. The Office of the Quartermaster General sold the horses because they were no longer fit for military duty, but were still serviceable for less demanding civilian needs.
Read about this volume in “No Horsing Around! Unusual Records in the National Archives” and then go to List of Horses Sold, February 1864 to take a look at the volume yourself.
All the names have been “tagged” so that a researcher could stumble upon this volume when doing a simple name search in the National Archives Catalog — but, beware! Names are not always spelled as expected!
