Colonel Chamberlain was badly wounded in the right hip and groin. It was considered a mortal wound and was reported as such in the newspapers, and General Grant promoted him to brigadier general based on the recommendation of Major General Gouverneur K. Warren. But Chamberlain recovered and returned to the army by the end of the year, serving until the end of the war. It is believed the wound was eventually responsible for Chamberlain’s death, 50 years later in 1914.
