On the first floor were about five hundred men.

On the second floor--where I was -- were about four hundred men.

These were principally from the First Division, First Corps distinguished by a round red patch on their caps; First Division, Second Corps, marked by a red clover leaf; and the First Division, Third Corps, who wore a red diamond.

They were mainly captured at Gettysburg and Mine Run.

Besides these there was a considerable number from the Eighth Corps, captured at Winchester, and a large infusion of Cavalry-First, Second and Third West Virginia--taken in Averill's desperate raid up the Virginia Valley, with the Wytheville Salt Works as an objective.
On the third floor were about two hundred sailors and marines, taken in the gallant but luckless assault upon the ruins of Fort Sumter, in the September previous.
