Answer :
Answer:
The bombing of Dresden.
Explanation:
Kurt Vonnegut was a POW during the infamous bombing of Dresden by the Allies forces towards the end of WWII. He survived this catastrophic event, which killed more people than the Hiroshima nuclear bombing, by hiding in an underground slaughterhouse. This would motivate him to later write his most famous novel, Slaughterhouse 5, and it would also change his outlook on time, free-will, humanity and kindness, all themes that he would elaborate upon in all of his fiction.
