Their mission was to stage sabotage attacks on American economic targets: hydroelectric plants at Niagara Falls; the Aluminum Company of America's plants in Illinois, Tennessee, and New York; locks on the Ohio River near Louisville, Kentucky; the Horseshoe Curve, a crucial railroad pass near Altoona, Pennsylvania, as well as the Pennsylvania Railroad's repair shops at Altoona;[5] a cryolite plant in Philadelphia; Hell Gate Bridge in New York; and Pennsylvania Station in Newark, New Jersey. The agents were also instructed to spread a wave of terror by planting explosives on bridges, railroad stations, water facilities, and public places. They were given counterfeit birth certificates, Social Security Cards, draft deferment cards, nearly $175,000 in American money, and driver's licenses, and put aboard two U-boats to land on the east coast of the U.S.[2]
