Howard was appointed
colonel of the 3rd Maine Infantry regiment and temporarily commanded a brigade at the
First Battle of Bull Run. He was promoted to
brigadier general effective September 3, 1861, and given permanent command of his brigade. He then joined
Maj. Gen. George B. McClellan's
Army of the Potomac for the
Peninsula Campaign. 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.
Failure at Chancellorsville At the
Battle of Chancellorsville, Howard suffered the first of two significant military setbacks. On May 2, 1863, his corps was on the right flank of the Union line, northwest of the crossroads of Chancellorsville.
Robert E. Lee and
Lt. Gen. Thomas J. "Stonewall" Jackson devised an audacious plan in which Jackson's entire corps would march secretly around the Union flank and attack it. Howard was warned by Maj. Gen.
Joseph Hooker, now commanding the Army of the Potomac, that his flank was "in the air", not anchored by a natural obstacle, such as a river, and that Confederate forces might be on the move in his direction. Howard failed to heed the warning and Jackson struck before dark, routing the XI Corps and causing a serious disruption to the Union plans.
Gettysburg At the
Battle of Gettysburg, the XI Corps, still chastened by its humiliation in May, arrived on the field in the afternoon of July 1, 1863. Poor positioning of the defensive line by one of Howard's subordinate division commanders, Brig. Gen.
Francis C. Barlow, was exploited by the Confederate corps of Lt. Gen.
Richard S. Ewell and once again the XI Corps collapsed, forcing it to retreat through the streets of Gettysburg, leaving many men behind to be taken prisoner. On
Cemetery Hill, south of town, Howard quarreled with Maj. Gen.
Winfield S. Hancock about who was in command of the defense. Hancock had been sent by Maj. Gen.
George G. Meade with written orders to take command, but Howard insisted that he was the ranking general present. Eventually, he relented. Controversy centers on three points: 1) Howard's choice of Cemetery Hill as the key to defense; 2) the timing of Howard's mid-afternoon order to abandon positions north and west of town; and 3) Howard's reluctance to recognize that Hancock, his junior, had superseded him. Historian
John A. Carpenter holds that Howard alone had wisely selected Cemetery Hill, that the order to withdraw was probably a sound one, and that the conflict between Howard and Hancock might have been avoided had Meade himself gotten onto the field. Howard started circulating the story that his corps' failure had actually been triggered by the collapse of Maj. Gen.
Abner Doubleday's
I Corps to the west, which was a partial reason for Doubleday's removal from command of the corps. However, the excuse was not accepted by history (the reverse was actually true), and the reputation of the XI Corps was ruined. Some argue that Howard should get some credit for the eventual success at Gettysburg because he wisely stationed one of his divisions (Maj. Gen.
Adolph von Steinwehr's) on Cemetery Hill as a reserve and critical subsequent defensive line. For the remainder of the three-day battle, the corps remained on the defensive around Cemetery Hill, withstood assaults by Maj. Gen.
Jubal Early on July 2, and participated at the margin of the defense against
Pickett's Charge on July 3. Also at Gettysburg, Howard's younger brother, Major
Charles Henry Howard, served as his aide-de-camp.

Western Theater with fellow general Henry Slocum's XII Corps to become part of the
Army of the Cumberland in
Tennessee; they were commanded once again by "Fighting Joe" Hooker. In the
Battles for Chattanooga, the corps joined the impulsive assault that captured Missionary Ridge and forced the retreat of Gen.
Braxton Bragg. In July 1864, following the death of Maj. Gen.
James B. McPherson, temporary command of the
Army of the Tennessee was given by order of
William Tecumseh Sherman to the ranking officer on the field that day, Major General
John A. Logan. Shortly after the success at the Battle of Atlanta, Sherman (who favored granting command to a West Point graduate) appointed Howard to permanent command of the Army of the Tennessee. At the closing of his "After Action Report" filed by Major General John A. Logan on September 10, 1864, Logan referred to his having served as Commander of the Army of the Tennessee for a scant four days. Logan's detailed report ended: "I withdrew the Army of the Tennessee the night of the 26th, and moved it along the rear of the center and right of the army to a position across Proctor's Creek. After putting the army in position that night I was relieved by Maj. Gen. Howard." Howard subsequently led the right wing of Maj. Gen. William Tecumseh Sherman's famous
March to the Sea, through
Georgia and then the
Carolinas. Sherman, having favored Howard over Logan for permanent command of the Army of the Tennessee, recognized Logan's success at Atlanta. In recognition of the outstanding leadership Logan displayed at Atlanta, Sherman asked Howard to allow Logan to ceremonially lead the Army in the May 1865 Grand Review in Washington. Howard agreed when Sherman appealed to him as a Christian gentleman. Ultimately, by the war's end, Gen. Sherman would commend Howard as a corps commander of "the utmost skill, nicety and precision". ==Postwar career==
