A German spy is passing on information about the location of Allied ships in the neutral harbor of Goa, India, with catastrophic results. Unable to undertake a full military operation in the Portuguese stronghold, English intelligence brings out of retirement a crew of geriatric ex-soldiers, veterans from World War I, using their age as cover. These old soldiers are asked to take to the seas and pull off an unlikely undercover mission.
The Sea Wolves is a 1980 war film starring Gregory Peck, Roger Moore and David Niven. The film, which is based on the 1978 book Boarding Party by James Leasor, is the true story of Operation Creek during the Second World War. In the covert mission, the Calcutta Light Horse, part of the Cavalry Reserve in the British Indian Army, successfully sank a German merchant ship in Mormugão Harbour in neutral Portugal's territory of Goa, India, on 9 March 1943. The ship had a secret radio which was transmitting information about Allied shipping to U-boats operating in the Indian Ocean.
