At the Battle of Chancellorsville in May 1863, the troops were warmly engaged, and many won the Kearny Medal of Honor (the Kearny Cross). The first two weeks of June were spent at Banks Ford, and then the troops started northward. At the Battle of Gettysburg, the regiment lost many men, and, after the return to Virginia, engagements followed at Auburn, Kelly's Ford, and Locust Grove in the Mine Run campaign late in November. At the end of that campaign, the regiment returned to the camp at Brandy Station for the winter, and, on December 28, 1863, nearly the entire regiment re-enlisted.
