Their mission was sabotage. Their targets were some of the crown jewels of America’s industrial might: major hydroelectric plants, important aluminum factories, critical railroad tracks, bridges and canals–and the water supply system of New York City.
Fortunately, their scheme was uncovered in time. None of the planned acts of sabotage were ever committed. Two of the saboteurs who cooperated with the United States got prison sentences. The other six were executed.
