Thomas Custer in the Yellowstone Expedition of 1873, where he fought in the Battle of Honsinger Bluff, and the Black Hills Expedition of 1874. Custer was appointed captain in 1875 and given command of Company C of the 7th Cavalry. In 1874, at the trading post at Standing Rock Agency, Custer participated in the arrest of chief Rain-in-the-Face (Lakota), suspected in the 1873 murder of Dr. John Honsinger. During the 1876 Little Bighorn campaign of the Black Hills War, he served as aide-de-camp to his older brother Lt. Col. George A. Custer and died with his brother on June 25, 1876. Lt.
Battle of the Little Bighorn Gall's version of events, as recounted to Lt. Edward Settle Godfrey, Custer did not attempt to ford the river and the nearest that he came to the river or village was his final position on the ridge. Chief Gall's statements were corroborated by other Indians, notably the wife of Spotted Horn Bull. Given that no bodies of men or horses were found anywhere near the ford, Godfrey himself concluded "that Custer did not go to the ford with any body of men". Cheyenne oral tradition credits Buffalo Calf Road Woman with striking the blow that knocked Custer off his horse
