Cape Cod's positioning on the edge of the continent has always invited inventors, explorers, fishermen and military strategists. During the height of World War II when the nation was shaking off the shock of Pearl Harbor and London suffered under the Blitz of Nazi bombers, the U.S. government quietly leased 1,700 acres of land in a sparsely populated corner of South Wellfleet.
Dubbed Camp Wellfleet, it was a Strategic Air Command Base, firing range and even a temporary bomb target area. The 548th Antiaircraft Artillery Battalion, an active-duty regular Army unit and later guardsmen and reservists trained there. Artillerists unleashed immense barrages from the bluff aiming for targets towed by small remote-controlled planes. The military declared the camp excess in 1961 and the whispering pines and dunes near the former Marconi Site became part of Cape Cod National Seashore.
If you look to the buildings on the right side of the aerial image, you can see what will eventually become Cape Cod National Seashore's park headquarters building!
