Following the costly failure of Operation Battleaxe, General Archibald Wavell was relieved as Commander-in-Chief Middle East Command and replaced by General Claude Auchinleck. The Western Desert Force was reorganised and renamed the Eighth Army under the command of Lieutenant-General Alan Cunningham and at this stage, the division comprised only two brigades. The plan for Operation Crusader (See Map 2) was to engage the Afrika Korps with the 7th Armoured Division while the 1st SA Division and the 22 Guards Brigade covered their left flank. Meanwhile, on their right, XIII Corps, supported by 4th Armoured Brigade (detached from 7th Armoured Division), would make a clockwise flanking advance west of Sidi Omar and hold position threatening the rear of the line of Axis defensive strongpoints which ran east from Sidi Omar to the coast at Halfaya. Central to the plan was the destruction of the Axis armour by 7th Armoured Division to allow the relatively lightly armoured XIII Corps to advance north to Bardia along the coast while XXX Corps continued northwest to Tobruk and link up with a planned break-out by the 70th Division.
