In the other letter, written from Atlanta, Ga., during the Civil War, Keogh tells his sister Ellen of his experiences as a prisoner of war for two months.

During Keogh’s service in the Civil War, he wrote to his sister about the loss of Tom, an old horse that he had loved much and that had carried him through many charges.

Comanche, the war horse, was the only survivor, and the regimental tune was "Garryowen." Capt. Myles Keogh owned Comanche, and he reportedly introduced "Garryowen" to Custer.

Keogh, who was born Ireland, previously fought in the papal army in Italy and earned a medal for heroism. He came to America to fight in the Civil War and caught the eye of Custer.
