at the battle of Wilson Creek, Missouri. For gallant conduct in the battle of Pea Ridge, Arkansas (in which he commanded a division, was wounded three times and saved the day) he was promoted brigadier-general of volunteers, and received the congressional medal of honor.
During the Vicksburg campaign he led a division and took active part in the operations against that stronghold. He commanded for a while the left wing of the sixteenth army corps with headquarters at Corinth, Mississippi; then the cavalry of the department of Arkansas, the district of Little Rock, the cavalry of the Camden expedition, and a division at the siege of Spanish Fort, near Mobile.
He has a brevet for nearly every grade in the regular army, from second lieutenant to major-general.
After the war, as major of the fifth United States cavalry, he commanded the post of Raleigh, North Carolina, and afterward was judge advocate and inspector-general of the Department of Washington, where he was employed in many confidential positions.

In 1876 he took part in the Big Horn and Yellowstone expeditions as lieutenant-colonel of the 5th cavalry; and in 1877 he rendered efficient aid in quelling the railroad strike riots in Chicago.
His promotion to colonel of the sixth cavalry followed in 1879.

The Indian scouts turned traitors, and they and the other Indians killed a captain and seven soldiers. Although he repulsed the Indians, brought his command back safely, and afterward successfully defended the post, it was announced that General Carr, with all of his officers and men, his wife and all the
