The conference also established a new theatre of war in South East Asia, with Lord Mountbatten as commander, and reached an agreement to dissuade Spain from supplying tungsten to Germany and to withdraw one of its divisions from the German-Soviet war.
The UK and USA also agreed that neither would use a nuclear weapon - now in rapid development - or communicate nuclear intelligence to a third party without mutual consent.
One of the stranger events at the Quebec Conference was the discussion of a plan to build an aircraft carrier out of ice. The mastermind behind this plan was a scientist called Geoffrey Pyke, who developed a substance he called Pykrete, made of frozen seawater and sawdust. A prototype was demonstrated at the Quebec Conference and the project had many high-powered supporters - but the plan was abandoned in favour of the artificial harbours that were constructed for the Normandy landings.
