The next day: 28 May 1942

The 21st Panzer Division and the Ariete Division were able to move on 28 May 1942. The 21st Panzer Division penetrated very far north and took "Commonwealth Keep". The 1st Armoured Division commander, General Lumsden, had wanted to attack the 21st Panzer Division with his two armoured brigades, but the 22nd Armoured Brigade stayed with the 15th Panzer Division. The 2nd Armoured Brigade did attack the Ariete Division west of Knightsbridge. The 1st Army Tank Brigade also hit the Ariete Division from the northwest at the same time. The 4th Armoured Brigade hit the 90th Light Division and pushed it to the south and west. This is based on the account in Vol.III of the Official History.
