This document comes from a pamphlet produced by the 321st Bombardment Group after the war, which told the story of the group's activities from 15 March 1943-15 March 1945 in the form of a newspaper.
Many thanks to Christine Stewart for sending us this document, which came from the collection of her father in law Eugene W. Stewart, a staff sergeant in transportation with the 321st Bombardment Group.
