[1] The U.S. Embassy in Athens was closed July 14, 1941, after the German occupation of Greece.

The United States maintained diplomatic relations with the government-in-exile of Greece in London (1941–43) and then in Cairo (1943–44).

This action also would promote Minister Biddle to the rank of Ambassador, which required a new appointment.

The appointment was promptly made by President Roosevelt and confirmed by the Senate.

Ambassador Biddle presented his credentials to the government of Greece on October 30, 1942.
