Okay, Brig. Gen. Thomas Ewing, Jr. did not fight at the Batle of Westport. But he was in command of the Federal forces who fought at the Battle of Pilot Knob (Fort Davidson).
Born in Ohio in 1829, Thomas Ewing Jr. was chief justice of the Kansas Supreme Court when the war began. In 1862 Ewing mustered in colonel of the 11th Kansas Infantry. Ewing rose to the rank of brigadier general during the war. In August 1863, while in command of the District of the Border in the Department of the Missouri, Ewing issued General Orders, No. 11. It was an order to weaken support for Missouri guerrilas and gave residents of the Missouri counties within his district 15 days to evacuate their farms.
Ewing resigned his commission a month before Lincoln was assassinated. He served as defense attorney for three of the men tried for assassinating Lincoln. Ewing remained in Washington, D.C., to practice law. Five years later, in 1870, Ewing returned to Ohio to practice law and was elected to Congress. Ewing ran unsuccessfully for governor of Ohio in 1880. After his defeat, Ewing moved to New York to practice law. William T. Sherman was his foster brother, having been raised in the Ewing family following the death of Sherman’s father.
