Grand Harbour in Malta, a British possession that initially served as a base for French as well as British ships. At the Malta conference, March 2 to 9, 1916, the French agreed move their base. They first went to Argostoli in Cephalonia, then to Corfu. In the message, the writer notes that they are no longer in Malta, but in Corfu, and that the enemy submarines are rather numerous.
