On this day in 1941 HMS/M Unbeaten sailed on her first operational war patrol from Malta. The British submarine was now a member of the 1st Submarine Flotilla. This Flotilla was originally made up of 12 submarines divided between Malta and Alexandria. Not until September 1941 did the U-Class submarines based at the Maltese island become the famed 10th Submarine Flotilla. Life at sea was dangerous. Several British submarines and their crew perished during their first patrol from the island. This period at sea for Unbeaten would be a testing time for her crew, during which she would see plenty of action.
