The International Committee of the Red Cross (ICRC) played a major role in working with POW's on all sides in World War II. It was in a cash-starved position when the war began in 1939, but quickly mobilized its national offices set up a Central Prisoner of War Agency. For example, it provided food, mail and assistance to 365,000 British and Commonwealth soldiers and civilians held captive. Suspicions, especially by London, of ICRC as too tolerant or even complicit with Nazi Germany led to its side-lining in favour of the UN Relief and Rehabilitation Administration (UNRRA) as the primary humanitarian agency after 1945.
