| 1915 | D 4 (I 74) | D4 had a lucky escape when she attacked the German minelayer Bielefeld which had gone aground in the Heligoland Bight. Her captain decided to sink the destroyer that was standing by the grounded minelayer before sinking Bielefeld. Unfortunately the torpedo missed and she found herself being hunted in the very shallow water (30 feet). The destroyer made repeated runs over the submarine in an attempt to ram the conning tower and they could do nothing but hope for the best. Eventually the destroyer made off and Moncreiffe was able to surface and sink the Bielefeld. |
