On June 30, 1863, the Battle of Hanover delayed Maj. Gen. J.E.B. Stuart and a 17-mile long column of supplies from getting to Gettysburg. Union cavalry under Brig. Gen. Elon Farnsworth (who died three days later at Gettysburg) arrived to stand in his way. Brig. Gen. George Custer also joined the fray, delaying Stuart's arrival at Gettysburg until the afternoon of July 2, to the consternation of Gen. Robert E. Lee.
