On June 12, 1917—that is, six weeks after the previous incident, just time enough to give leave to all the crew, get the ship refitted and sailed to her new area—_Prize_ left Killybegs (Ireland) to cruise to the westward of the Irish coast. At 11 a.m. on this day she was under all sail on a N.N. W. course, doing not more than a knot through the water, when she sighted a submarine 1-1/2 miles to the E.S.E. proceeding slowly on the same course as _Prize_. The movements of this submarine thereafter are worth noting. It is only reasonable to suppose that on his return to Germany in U 93 Ziegler would give a full description of the trap-ship which had so nearly destroyed him. This information would, of course, be passed on to the other submarine captains who frequented this Irish area, and we may be quite certain that they would be on the look-out for her, anxious to revenge their service. Now, in these modern times, and in any twenty-four hours, you will see far more steamers of all sorts than 200-ton sailing craft: it certainly was so during the war off the west and south-west coast of Ireland. During the years I was on patrol there, with the exception of quite small local fishing craft and an occasional full-rigged ship making the land after her voyage across the Atlantic, one scarcely ever sighted a sailing vessel of any kind. Ziegler would have reported in effect: ‘Look out for a three-masted topsail schooner of about 200 tons. She has a bow like this..., her stern is like this..., and her sheer is so.... You will probably find she has a dummy deckhouse placed here...;’ and a rough sketch would afford his comrades a pretty accurate idea. You cannot ever disguise the appearance of such a sailing ship altogether, no matter what name you give her, nor what colour you paint her hull. A three-masted topsail schooner is that and nothing else, and would henceforth be regarded with the utmost suspicion. Then, on comparing her with the sketch and examining her with the eye of seamanlike experience, no astute submarine officer could have had much doubt in his mind. A British officer who knew this ship well has told me that in his opinion there was one small detail, in respect of the wireless, which, to a careful observer, would always give her character away. This may be so: at any rate, the following incidents seem to indicate that the enemy were on the look-out for her during the rest of her career, and persistently attacked her.
