General Montgomery realized at the end of the Battle of Alam el Halfa that the Eighth Army was not ready for an attack with the aim of busting open the front. He still wanted time to prepare for the big attack. After the end of the last battle, he wanted to only harass the enemy, although he would proceed with General Freyberg's planned attack to close the minefield gaps.
That attack would begin late on 3 September 1942. The 132nd Infantry Brigade had been replaced in the line by the 5th Indian Brigade, so it became available for the planned attack. The attack would consist of two three mile advances. The second would have the 151st Infantry Brigade by 4 September. The 7th Armoured Brigade would attack to the west in support of the operation.
The attackers on 3 September consisted of the 132nd Infantry Brigade and the 5th New Zealand Brigade with supporting Valentine tank squadrons. This is based on the account in Vol.III of the Official History.
