Thomas Weir (American soldier) Thomas Weir (American soldier) Captain Thomas Benton Weir (b. September 28, 1838 -– d. December 9, 1876) was an officer in the 7th Cavalry Regiment (United States), notable for his participation in the Battle of the Little Bighorn, also known as Custer's Last Stand. Weir served under General George Armstrong Custer during the American Civil War, and after the war continued serving with Custer up to the famous battle in 1876. During the Little Bighorn Battle, Weir disobeyed orders to remain in a defensive position at Reno Hill and led a cavalry group that attempted to come to Custer's aid.
Battle of the Little Bighorn before he died. Having isolated Reno's force and driven them away from the encampment, the bulk of the native warriors were free to pursue Custer. The route taken by Custer to his "Last Stand" remains a subject of debate. One possibility is that after ordering Reno to charge, Custer continued down Reno Creek to within about a half-mile (800 m) of the Little Bighorn, but then turned north and climbed up the bluffs, reaching the same spot to which Reno would soon retreat. From this point on the other side of the river, he could see Reno charging the village.
