The position was about 25´ south of Beachy Head. "C 15" was on patrol in rather misty weather, and at the time of sighting the enemy both boats were on the surface, U-C 65 steering home up Channel, "C 15" steering N. by E. across her bows. Both boats saw each other at the same time, and the German watched the English boat go under to attack. The obvious reply was to either dive also or to alter course and pass round the "danger-radius" of the torpedoes on the surface. The German Captain had two mental handicaps--over-confidence and (having just finished a long trip) over-anxiety to get home on leave. He decided not to alter course or delay his passage, but explained to his First Lieutenant that it was quite easy to dodge a torpedo if a good look-out was kept and the helm moved quickly. The First Lieutenant appears to have had philosophic doubts as to the wisdom of the proceeding, his doubting being justified when, on seeing the firing-splash as "C 15" fired, the Captain neatly dodged one torpedo and received the other fairly amidships. Lieutenant Dolphin had fired two--"spread" slightly for deflection; not having "declared to win" with either, the question of which one hit did not trouble him. U-C 65 probably won a moral victory, but--"C 15" sank her. The C boats working round the N. Hinder Light-vessel were liable to make sudden "contacts" with the enemy, usually in thick weather or at night. Both sides would be trying to make the lightship to fix their positions, and on occasions two belligerent submarines would make the lightship together.
