On June 1, 1862, while commanding a Union brigade in the Fair Oaks, Howard was wounded twice in his right arm, which was subsequently amputated. (He received the Medal of Honor in 1893 for his heroism at Fair Oaks.) Brig. Gen. Philip Kearny, who had lost his left arm, visited Howard and joked that they would be able to shop for gloves together. Howard recovered quickly enough to rejoin the army for the Battle of Antietam, in which he rose to division command in the II Corps. He was promoted to major general in November 1862 and assumed command of the XI Corps the following April, replacing Maj. Gen. Franz Sigel. Since the corps was composed largely of German immigrants, many of whom spoke no English, the soldiers were resentful of their new leader and openly called for Sigel's reinstatement.
