Tickets? LOL, there wasn't any tickets. People on the ship were P.O.W.s, rescued from Andersonville, an infamous Confederate prison camp. The boat was only capable of holding 376 people but the Union army insisted the boat take on more solders eager to reach Cairo, IL., where soldiers and P.O.W.s were to be mustered out of service. The enormous load totaled 2,200 people, plus 60 horses and mules and 100 hogs.
One of the boilers couldn't handle the stress and BOOM!
Manny, is it the Wilhelm Gustloff? At least 5,400 perished in that disaster.
