Just before noon on 20 June 1940 the following merchant ships sailed from Le Verdon for Falmouth: the KASANGO with 100 British passengers; the NIGERSTROOM with 600 British passengers; the VILLE DE LEIGE with 200-300 Polish and Czech troops and the BROOMPARK with unknown number of British nationals and machine tools. The brief mention of 'machine tools' on the BROOMPARK hides a more interesting story. Denholm's almost new tramp ship BROOMPARK was under the command of Captain Olaf Paulsen when she arrived at Bordeaux to load. The only place where heavy water (deuterium oxide) could be isolated was at the Norsk Hydro Ryukan plant in Norway. By the end of 1939, Ryukan was receiving orders from the German chemical giant I.G. Farben for up to 100 kg of heavy water a month. French intelligence became aware of the increased German demand, and, in early March, Lieutenant Jacques Allier, a Deuxième Bureau agent, managed to spirit the entire Ryukan 165 Kg of heavy water, in 26 five-litre containers, out of the country. When France was invaded the French nuclear scientist Jean Frédéric Joliot-Curie1 took charge of the material, hiding it first in a Banque de France vault and then in a prison. Joliot-Curie then moved it to Bordeaux, where it, plus research papers and most of the scientists ( Joliot-Curie remained in France) boarded the BROOMPARK. The ship already had industrial diamonds, machinery and a number of British evacuees aboard. BROOMPARK delivered her passengers and cargo, together with all of the free supply of heavy water, to Falmouth on the 21 June. The award of an OBE to Captain Paulsen was recorded in the London Gazette of 4 February 1941. Any additional information would be most welcome - especially Captain Paulsen's report, if he made one.
