Early 1941 was a good time for British naval forces operating near Malta

The first five months of 1941 were quite successful for British naval forces operating near Malta. We have already discussed the surface forces, but there were also the larger submarines which operated in deeper water and the much smaller U-class which operated in the shallows off Tunisia and Libya near Tripoli. The greatest successes of this period were the sinking of the Italian light cruiser Armando Diaz by Upright and the liner Conte Rosso by Upholder. Lt-Commander Wanklyn received the Victoria Cross for what was called "a daring attack" on the Conte Rosso. Unfortunately, two U-class submarines, the Usk and Undaunted were lost, as well. This is based on the account in Vol.II of the Official History.
