Operation Sunrise: America’S OSS, Swiss Intelligence, and the German Surrender 1945
Operation Sunrise: America’s OSS, Swiss Intelligence, and the German Surrender 1945 by Stephen P. Halbrook* Operation Sunrise was a cooperative effort of American and Swiss intelligence services which led to the unconditional surrender of the German Wehrmacht forces in Northern Italy and Western Austria on May 2, 1945. General Heinrich von Vietinghoff, Commander-in- Chief of the Southwest Command and of Army Group C, surrendered nearly a million soldiers, the strongest remaining German force. This was the first great surrender of German forces to the Allies, and became a strong impetus for the final Allied victory over Nazi Germany on May 8, Victory in Europe (VE) Day. Operation Sunrise helped to nip in the bud Nazi aspirations for guerilla resistance in an Alpine redoubt. Sunrise, sometimes referred to as “Crossword,” has special significance today beyond the sixtieth anniversary of the German surrender. Despite Switzerland’s formal neutrality, Swiss intelligence agents aggressively facilitated American efforts to end the war. Ironically, the efforts of key U.S. intelligence agents on the ground to orchestrate the surrender were hampered and almost scuttled by leaders in Washington to appease Joseph Stalin, who wished to delay the surrender in the West so that Soviet forces could grab more territory in the East. *This paper was originally presented at the conference Sunrise ‘05, Locarno, Switzerland, May 2, 2005, and was published in “Operation Sunrise.” Atti del convegno internazionale (Locarno, 2 maggio 2005), a cura di Marino Viganò - Dominic M. Pedrazzini (Lugano 2006), pp. 103-30. The conference was held to commemorate the 60th anniversary of the surrender of German forces in northern Italy.
