This is the regulation 35-star cavalry guidon that was carried by Mounted Union Troops in the Civil War. The inner circle contains 12 stars, the outer circle includes 19 stars, and each corner includes a single star. It usually would be “customized” by placing a troop letter or other designator inside the circle of golden stars.
The U.S. Cavalry later used Stars and Stripe guidons in the Plains Indian Wars. In fact, the cavalry was the last of the three branches of service of the U.S. Army to carry the Stars and Stripes into battle. This was also one of the three flags that Colonel George A. Custer and the Seventh Cavalry carried at the Battle of Little Big Horn.
