With my best wishes for your future success, believe me, my dear Captain,
Faithfully yours,
The records show that the mystery ships sank twelve submarines, of which Captain Campbell accounted for four; yet this was perhaps not their most important achievement. From the German standpoint they were a terribly disturbing element in the general submarine situation. Externally a mystery ship, as already described, was indistinguishable from the most harmless merchantman. The cleverness with which the Allied officers took advantage of the vicious practices of the submarine commanders bewildered them still further. Nothing afloat was sacred to the Hun; and he seemed to take particular pride in destroying small vessels, even little sailing vessels. The Navy decided to turn this amiable trait to good account, and fitted out the Prize, a topsail schooner of 200 tons, and placed her under the command of Lieut. William Sanders, R.N.R. This little schooner, as was expected, proved an irresistible bait. A certain submarine, commanded by one of the most experienced U-boat captains, attacked her by gun fire from a safe distance and, after her panic party had left, shelled her until she was in a sinking condition; many of her crew had been killed and wounded, when, confident that she could not be a Q-ship, the enemy came within less than 100 yards. It was promptly fired on and disappeared beneath the surface. The panic party picked up the German captain and two men, apparently the only survivors, who expressed their high admiration for the bravery of the crew and assisted them to get their battered craft into port. The captain said to Lieutenant Sanders: "I take off my hat to you and your men. I would not have believed that any men could stand such gun fire." For this exploit Lieutenant Sanders was awarded the Victoria Cross. Within about four days from the time of this action the Admiralty received an inquiry via Sweden through the Red Cross asking the whereabouts of the captain of this submarine. This showed that the vessel had reached her home port, and illustrated once more the necessity for caution in claiming the destruction
