Unfortunately, my g-grandfather missed out on the march into Vicksburg, having been taken captive at Champion's Hill and sent to Libby Prison. He was paroled in time for the assault on Missionary Ridge, near Chattanooga, and went with "Uncle Billy" through Georgia and the Carolinas. I assume that the gun I have is the second one he carried, unless the CSA was kind enough to return his original to him. In Alonzo Brown's "History of the 4th Minnesota," there are references to "our Whitneys." the 4th bore the brunt of Hood's assault at Allatoona Pass, where the Southern troops fought with incredible vigor, because they were starving, and coming for the stores at the pass. This was very upsetting to the Union troops, because they had been fighting these same CSA units in previous battles, and were angry at how emaciated they were, when they were finding plenty of food at plantations, which was being withheld from their own army. The 4th was also the lead unit assaulting Missionary Ridge, and was on point for one of the war's last battles at Bentonville. When they arrived in D.C. for the Grand Review, many of the soldiers weren't allowed to march, because they were nearly naked from the long march without much in the way of re-supply. The soldiers on both sides were amazingly tough and resilient, and probably suffered more than in any other war. Of course, the War of Independence was no cake-walk either, and I have ancestors who fought in that one, too.
