This was a British unrealised plan to draw the Luftwaffe into major combat over the north coast of German-occupied France (October/November 1942).
Designed to provide support for 'Overthrow' at the time of 'Torch' and later redesignated as 'Coleman', the plan was to have been based on a naval demonstration off the coast near Berck in conjunction with the drop of dummy paratroops and the landing of a small party of No. 12 Commando to persuade the Germans that a major landing was about to be made, thereby eliciting a major German air response.
This would be useful, it was hoped, in slowing of not actually preventing the Germans from rushing air reinforcements to North Africa. The plan was cancelled, however.
