A grands traits, l'opération visait à s'emparer de Dieppe et établir autour de la ville un périmètre à l'intérieur duquel le Génie procéderait à une destruction massive. Il devait, notamment, faire sauter "cales sèches, ponts tournants, installations portuaires, matériel roulant, centrales d'énergie et de gaz et tout objectif de ce genre""'.
Very broadly, the scheme of the operation was to capture Dieppe and establish around it a perimeter within which extensive demolitions would be carried out by the Engineers, who were to destroy "the dry docks, swing bridges, harbour installations, rolling stock, power and gas works and any other suitable objective".171 Outside the perimeter the Camerons and the tanks would operate against the aerodrome and the supposed divisional headquarters.Giga-fren Giga-fren
