Correction, Detroit, Michigan. From the website MHUGL "Military History of the Upper Great Lakes":
"... During both world wars it was used as a shipping center that sent vehicles and weapons manufactured in Detroit to the fronts of the war. During World War II the fort housed Italian prisoners of war. During the Detroit riots the fort provided housing for families whose houses were destroyed.
Fort Wayne was one of the largest motor supply depots in World War II and additional buildings were constructed near the fort to warehouse the weapons and vehicles being sent the fronts of the war. Equipment was sent out on ship by the Detroit River or by the railroad that used to run next to the fort."
Likely myriad parts for the war effort went out through the Great Lakes.
