The part played by the submarine which destroyed the viaduct, and by her attendant picket-boat, must not be overshadowed by the deathless tale unfolding in the bullet-whipped waters of the adjoining harbour, and along the bloodstained parapet of the mole. It is deserving of a Saga all its own, but until that is written, the tale is best told simply, halting though the prose. Owing to a breakdown, only one submarine reached Zeebrugge, under the command of Lieutenant Sandford, R.N. The mole was sighted silhouetted against the blaze of guns and searchlights: and under a heavy fire of 4-inch shell the craft, with her cargo of high explosives, was launched at full speed at the rows of piers supporting the viaduct. She struck at right angles, riding up on to the horizontal girders and penetrating up to the conning-tower. The crew then launched the skiff, ignited the fuses, and pulled clear, while a company of riflemen on the viaduct above opened fire upon them with machine-guns, rifles, and pompoms. They continued pulling against a strong tide, and although nearly all were wounded (Lieutenant Sandford twice) and the boat only kept afloat by use of a specially designed pump, succeeded in getting about 300 yards clear before the explosion took place. As was anticipated, a gap of 150 feet was blown in the viaduct: concrete, girders, men, guns, and searchlights being hurled to the skies in a column of flame. The attendant picket-boat then swooped down and rescued the occupants of the skiff, transferring them later to one of the destroyers in the offing. The rescue was carried out under most hazardous conditions, and the little steamboat, manned by a crew of volunteers, with her fore compartment full of water, returned to England under her own steam, and thus completed a journey of 170 miles. One British destroyer which lost herself in the smoke, found herself, when a gust of wind blew the smoke clear, well inside Zeebrugge harbour; she had time, however, to discharge all her torpedoes at the vessels alongside the mole before she was disabled by shell fire. She struggled a couple of hundred yards outside the entrance to the harbour and lay there a helpless log, sinking fast. A sister destroyer, under command of Lieutenant-Commander H. E. Gore-Langton, R.N., swooped down upon her and circled round until she was enveloped in smoke, under cover of which the crew were disembarked. Attempts were made to take her in tow, but the hawser was twice shot away. Her Captain, Lieutenant-Commander K. C. Helyar, R.N., remained on his shattered bridge to the last, and only abandoned her when she was sinking under him. Back across the Channel as the day was breaking came the _Vindictive_, _Iris_, and _Daffodil_, their task accomplished, and their names flashing proudly to the uttermost outposts of the Empire.
