In the midst of World War II, America had not yet entered the fight, but President Roosevelt knew they had to help Britain get back into occupied territory, which would be achieved through highly trained secret agents. The only problem? America had no secret agents.
So, they created “Special Training School 103”, or “Camp X”: the first spy training school in North America, with British Intelligence to train them. But, because the they hadn’t officially entered the war, it couldn’t be on U.S. soil. So, the Allies placed the top secret facility on a remote site near Lake Ontario, yet only 30 miles straight across the lake from the U.S.; Not even the Prime Minister was told what was happening there.
