In August 1942 No. 3 Commando was involved in the ill-fated Operation Jubilee, an exploratory raid on Dieppe in France. The plan called for a frontal assault on the port by the Canadian 2nd Division. Before this would take place, however, Troops from No. 3 and 4 Commandos would land at beaches on the eastern and western flanks and neutralise two German artillery batteries that were covering the main anchorage. No. 3 Commando was assigned the task of attacking the Goebbels Battery, landing on the eastern flank, under Durnford-Slater's command. The battery was located near Berneval-le-Grand, about half a mile from the sea with steep cliffs in front of it. It was decided that No. 3 Commando would land on two beaches to the east and west of the battery, from which gullies rose towards the battery and which would provide concealment while the Commandos approached the battery.
