On November 5th the _Tara_ was torpedoed by a German submarine in the Gulf of Sollum, and sank with the loss of eleven of her crew of something over one hundred. The ninety-two survivors were towed by the submarine to Port Sulieman and handed over to the Turks. The latter, in turn, passed the party on to the Senussi, who, as shortly transpired, were getting ready to launch a "holy war" against the Italians and English. The Arabs, short of food already, started marching their prisoners about the desert, and after several weeks established them in a sort of permanent camp at an old Roman well in the interior. Here, ekeing out with snails and roots such scanty rations as their captors were able to provide, the unfortunate Britons, racked by disease, and only half sheltered from the capricious winter weather, existed for three months and a half. The trickle of food, now from one oasis, now from another, became thinner and thinner as time went on, and by the middle of March the failure of supplies had become so complete that absolute starvation in the course of the next few days appeared inevitable. But on the seventeenth of that month, as suddenly as though dropped from the sky, a squadron of armored automobiles appeared on the horizon, and a few moments later the Arab guards had fallen before the fire of machine-guns, and the half-delirious prisoners, clutching hastily-broached jam and condensed milk tins, were being bundled into Red Cross ambulances for the return journey. A couple of days more, and they were in the hospitals of Alexandria, and a month later the bulk of them were back in England reporting for duty. Through the courtesy of the British Admiralty the writer was granted an extended interview with Captain Gwatkin-Williams--the only one, indeed, that that distinguished officer gave before going to his new command in the North Atlantic. Later I journeyed to Wales and Ireland, to talk with Lieutenant Tanner, R.N.R., and several of the surviving members of the _Tara's_ crew. The narrative that follows is the result of these conversations. I recognized Captain Gwatkin-Williams the instant his broad shoulders filled the door of the room. I knew at once that he had all the characteristics, as he had all the appearance, of the typical British naval officer, and that among these was a distinct disinclination to tell of his own experiences. Knowing from past failures the futility of trying to "draw" a man of his kind by frontal attack, I wasted no effort in that direction, but asked him pointblank if he had been able to preserve any souvenirs of his desert sojourn, and it is by piecing together the things he told me over a brine-blotched naval uniform, a dented jam tin, a handful of snail-shells and dried roots, three or four camel-bone needles, and a blood-stained whip of hippo hide, that I was able to construct the connected story which follows. * * * * *
