During World War II, the city of Evansville manufactured vast amounts of armaments that were vital to the Allied victory. The Evansville Ordnance Plant made 96 percent of all .45-caliber ammunition used in the war, while the Republic Aviation Plant produced more than 6,500 P-47 Thunderbolts—almost half of all P-47s built during the war. At its peak, the local shipyard employed upward of eighteen thousand men and women who forged 167 of the iconic Landing Ship Tank vessels. In this captivating and fast-paced account, University of Evansville historian James Lachlan MacLeod reveals the enormous influence these wartime industries had on the social, economic and cultural life of the city.
