In 1940, World War II began, and the plans were put on hold. As a goodwill gesture to the government, Robert C. Graham rented the land to the United States Air Corps for $1 per year. The Air Corps used this land to train their soldiers and established a Prisoner of War camp. The ocean front area was used as a rifle range and the barracks were set up on the west side of Collins Avenue. The camp for prisoners was located where the Bal Harbour Shops are presently.
