Colonel Samuel S. Carroll's brigade of the Second Corps filed through Huntington's Battery on their way toward the Cemetery gate and then down the hill to hasten the departure of the Confederates on the night of July 2. "Carroll sung out, 'Where is Huntington?' 'Here I am, General,' said I. 'I am sent here' he continued, 'to support something or some one - where is the enemy?' I showed him their advancing line, and commanded, 'Forward! double quick march!" And in they went." [History of Marietta and Washington County, Ohio, ed. by Martin A. Andrews]
By the way, Carroll claimed quite a bit of credit for saving Cemetery Hill, but his light casualties tell a different story. The fight was pretty much over by the time he charged over and down the hill, which corresponded with the time that the last organized body of enemy troops - the 6th North Carolina - was just withdrawing. The Eleventh Corps did not really need the help, but with their reputation, many in the army tended to believe Carroll's version of having saved the day.
