A Scottish Trawler Goes To War (continued part 2)

For her role as a magnetic mine hunter, CLYTHNESS was equipped with a minesweep consisting of twin insulated copper cables, one longer than the other, with bare electrodes at either terminal, both lengths kept afloat by compressed tennis balls within an outer cover, the overall diameter of each being 4". This apparatus was streamed astern, receiving a high voltage of electric current from a large number of batteries charged by twin Ford V8 engines situated in the forepeak, thus creating the electrical field which detonated the mine. A time switch was regulated to give five second pulses at fixed intervals, this being related to the vessel's speed in order that the area astern could be thoroughly searched. Whilst sweeping in pairs, or three abeam, station

had to be rigorously kept for the same reason. With few exceptions, all hands were required to manhandle and deposit the complete length of sweep over the stern from its storage lengthwise either side of the deck, and this could be a considerable physical effort if adverse weather conditions prevailed. The procedure was reversed on the conclusion of sweeping. The luxury of mechanical winding on large drums came later with the advent of safer and more modern timber-hulled minesweepers

Sweeping out of Harwich and Sheerness we went through our baptism of fire, so to speak, detonating our first magnetic mines. In what was literally a graveyard of ships, we continually passed the visible wrecks of the Dutch liner SIMON BOLIVAR, the Japanese liner TERUKINI MARU, the British destroyer GIPSY and others, all recently sunk by magnetic mines. Shortly we were dispatched to Dover, where a large number of merchant vessels, unprotected by degaussing, were immobilised at anchor in the Downs, and that first night we could see the parachutes of descending mines dropped by enemy aircraft. We weighed anchor at dawn and thereafter detonated a fair number of magnetic mines. One large freighter we passed on an outward leg had only some wreckage to show on our return, having swung at anchor.

Then came two trips to Zeebrugge. On the second, we swept the harbour at first light in order to enable blockships to be sunk at the canal entrance, the capture of the town being imminent. Dunkirk came next with all that entailed. I remember volunteering for our small boat crew, lowered to search for survivors from a bombed ship sunk during the night, my Aldis signalling lamp making an efficient portable searchlight for locating survivors, many of whom were in bad shape. We made two trips, on both occasions crammed to the gunwhale with exhausted British and French troops.

I recall an odd occurrence which took place during that particular period. In the middle of the English Channel, we had spotted a life size replica of a cockerel actually standing on the surface of the water and moving over the waves. We picked him up and found that his legs were fixed to timber wreckage, and he was obviously a survivor from a sunken vessel. Further to receiving a resplendent coating of colours, he took pride of place thereafter as our mascot, standing proudly facing ahead on our bridge platform. Our skipper departed thereafter to sail a converted whaler from Ardrossan to the Middle East, where he was subsequently awarded the DSC.

After the fall of France, CLYTHNESS was to be permanently based at Dover, which had become the nearest place in Britain to enemy occupied territory. As we could be spotted from the French coast in fair weather whilst sweeping the war channel, we were liable to be bombed and straffed by enemy aircraft, once being straddled by a stick of bombs even with fighter protection, low cloud base being the problem. As a consequence, sweeping required to be carried out during hours of darkness. Strong tides and the proximity of the Goodwin sands combined once to find a sweeping partner requiring a tow from the latter by the tug LADY BRASSEY from Dover.

Then came the first shelling from heavy artillery sited on the French coast. The trawlers which formed the majority of sea-going vessels in the harbour were instructed to depart, only for the gunfire to follow us towards the direction of Ramsgate. At 23 miles distant, no accuracy could be achieved, but from then on over the next two years, a shell would be intermittently dropped into the harbour area. CLYTHNESS received a near miss on two occasions. On one there were no casualties as all the crew were below decks. On the other our Steward was killed instantly, and our Cook received serious injury, the only persons on deck level when the shell exploded. Each time our ship was heavily riddled with shrapnel above the water-line.
