A large number of the men from Vaughn's Brigade [60th, 61st, and 62nd Tennessee Infantry] were captured at the Battle of Big Black Bridge on May 17, 1863. I do not have a count of the number captured from these specific regiments and transported north. The total number of Confederate soldiers captured at Champion's Hill [May 16, 1863] and Big Black Bridge, and transported north, was approximately 4,400 officers and men.
These POWs were sent north to Camp Morton where the officers were separated out and sent to Johnson's Island. Most of the enlisted men were quickly forwarded to Fort Delaware arriving in mid-June 1863. Vaughn's Tennessee regiments were fairly new to Confederate service and the men suffered disproportionately from disease during the first three months of their incarceration. Some 15 are buried in Crown Hill Cemetery in Inianapolis and another 69 buried at Finns Point National Cemetery in Salem County, NJ near Fort Delaware.
The survivors of Vaughn's Brigade were placed in the lines at Vicksburg at Fort Hill overlooking the mouth of Mint Spring Bayou. They were reinforced by Mississippi State troops and stragglers from Loring's Division.
The surrendered Vicksburg garrion was released on parole, to go wherever they pleased to await exchange. Exchange meant that they could legally return to active duty. Pardons came after the war and involved taking the Oath of Allegiance.
