When the Civil War began, Willcox was practicing law in Detroit. He was appointed colonel of the 1st Michigan Volunteer Infantry. He was wounded and captured in the First Battle of Bull Run (First Manassas) while in command of a brigade in Maj. Gen. Samuel P. Heintzelman's division. He later received the Medal of Honor in 1895 for most distinguished gallantry during the battle. After his release and exchange more than a year later, on August 19, 1862, President Abraham Lincoln appointed Willcox a brigadier general of volunteers, to rank from July 1, 1861. The President had to submit the nomination three times, the last on March 7, 1863, before the U.S. Senate finally confirmed the appointment on March 11, 1863. Willcox commanded the 1st Division of Maj. Gen. Ambrose Burnside's IX Corps in 1862. He led the division at the Battle of Antietam and the corps at the Battle of Fredericksburg. During the 1863 draft riots, Willcox commanded the District of Indiana and Michigan. He again led a division at Knoxville and during Lt. Gen. Ulysses S. Grant's Overland Campaign. On December 12, 1864, President Abraham Lincoln nominated Willcox for appointment to the brevet grade of major general of volunteers to rank from August 1, 1864, and the U.S. Senate confirmed the appointment on April 14, 1865. Following the Siege of Petersburg, he led the first troops to enter Petersburg, Virginia, before ending the war serving in North Carolina. He was mustered out of the volunteers on January 15, 1866.(Wikipedia).
