Depending on the success of VIII Corps attack, I Corps would then launch two supporting operations codenamed "Aberlour" and "Ottawa". In the former the 3rd Infantry Division, supported by a Canadian infantry brigade, would attack north of Caen; the latter would be a move by the 3rd Canadian Infantry Division and the 2nd Canadian Armoured Brigade to take the village and airfield of Carpiquet. Originally planned for 22 June, Epsom was postponed until 26 June, to make up deficiencies in manpower and materiel. The initial opposition was expected to come from the depleted 12th SS Panzer Division Hitlerjugend ("Hitler Youth"), elements of the 21st Panzer Division, and the Panzer Lehr.
