Well the regiment as a whole never surrendered. There are only two times that I know of that endangered the flag. One, the color bearer was carrying the colors in a pirogue and overturned. A detail sent for the specific purpose of finding the flag eventually did although it took them a while. The second was at Labadieville and one union soldier wrote this account. "The Thirteenth was now started in pursuit of the beaten centre, following up Perkins's cavalry and a section of artillery, the guns of which we could hear booming, farther and farther away, for half an hour afterward. On the road and in the swampy wood behind the rebel position we took a field-piece and nearly three hundred prisoners. The color sergeant of the Crescent Regiment was caught, up to his waist in mire, but he had hid his colors, probably by burying them in the morass; and so the Twelfth failed to secure a rightful trophy." I've never found this account verified by a member of the Crescent.
