Codename Nemo
On June 4, 1944—two days before D-Day—the course of World War II was forever changed. That day, a US Navy task force achieved the impossible—capturing a German U-Boat, its crew, all its technology, Nazi encryption codes, and an Enigma cipher machine. Led by a nine-man boarding party and the maverick Captain Daniel Gallery, US antisubmarine Task Group 22.3’s capture of U-505 in what was called Operation Nemo was the first seizure of an enemy ship in battle since the War of 1812, one of the greatest achievements of the US Navy, and a victory that shortened the duration of the war.
