On 10th January 1941, Commander G.W.G. ('Shrimp') Simpson, RN, arrived in Malta and took up his duties as Commander (Submarines), Malta. His orders from the C-in-C Malta, were simple,
'Stop all supplies from Italy to Tripoli'

Between January 1941 and December 1942, the Italians lost 171 ships in the Mediterranean, totalling over half a million tons. A high proportion of those losses were inflicted by the submarines of Malta, supported by those from Alexandria/Beirut and Gibraltar. Losing half a million tons of shipping was key to the Axis defeat in North Africa.

However, to this fine record we must add some sad details. Unbeknown to the commanders of the successful submarines, some of the Italian shipping sent to the bottom of the Mediterranean carried British and Allied Prisoners of War:
