Situ- ated on a precipitous rock shelf some 300m above a river, the plant was regarded by the Germans, with good cause, as virtually impregnable. Prime Minister Winston Churchill and US President Franklin D Roosevelt were agreed on one thing: that the Nazis' capability of producing the world's first weapon of mass destruction must be stopped at all costs. The most efficient way that that could be achieved was by sabotaging the Norsk-Hydro plant, thus cutting off the supply at source. If this could be done it would allow the Allies to regain time lost in the race for the bomb. The units tasked with the mission were 9 Fd Coy (Airborne) and 261 Fd Park Coy (Airborne) of the Royal Engineers, part of the 1st Airborne Division, and would be their first operation. The plan was for glider-borne landing in a remote area five hours' march from the plant. The towing aeroplanes would be guided by radio location devices operated by the Norwegian Resistance, who would lead the attacking party of 34 commandos to the objective. Once the mission was complete, the group were to extract across the mountains into neutral Sweden – some 400km – and contact the British Consulate. This plan is now regarded as extremely naïve, as none could ski and, at best, they had learned a few basic Nor- wegian phrases, such as 'I am going to the dentist.' The operation, code-named 'Freshman', was an unmitigated disaster. On a bleak evening on 19th November 1942 the group took off from RAF Skitten in Caithness, Scotland, in two wooden Horsa gliders towed by specially adapted Halifax bombers, for the daunting 400-mile journey across the North Sea to Norway. In the first glider, commanded by 20-year-old Lt David Meth- ven, was Lance Corporal Trevor Louis Masters of 9 Fd Coy, known as 'the Shiny 9th'. Described as 5' 7" tall, with blue eyes and blond hair, Masters' service record shows that he was born in Glamorgan, Wales. At the time of the raid he was 25 years old and married to Teresa Jane (Jennie) née Keogh, of Harbour Terrace, Cóbh. Jennie was pregnant with their first child, subsequently named Jean, who was born two months premature in February 1943, weighing just 2lbs.
