1918 ‘On Active Service’ cover to England posted from F. P. O. No. 78 (Basra) that has a boxed cachet ‘DAMAGED BY IMMERSION / IN SEA WATER’ on the front and on the back A ‘Found Open and Officially Secured’ label that has a London F.S. 21 / 7 MR 18 cancellation. Nothing is known of this incident although three other covers are recorded from Iraq, Palestine and India, two of which have endorsements mentioning being torpedoed. A scarce and interesting item.
