Gen. Custer’s Farewell Order
The following is a copy of Gen. Custer’s last order to his soldiers at Appomatox in 1865. Our granger friend I. N. Cooper was a soldier in his command , and the order is still as familiar to him as the face of the gallant commander was at the time. Mr. Cooper says the boys always dreaded to have the General in their immediate vicinity during a battle, as there were always a few thousand more bullets flying around him than in any other part of the field….
