The flawed command structure

The planned attack on the Cauldron was to be mounted with no single officer in command. Instead, there were these independent units involved, but operating on their own. The plan sounds like another typical 8th Army operations, with the forces sent off in all directions, acting alone. The 10th Indian Brigade would attack to the west. The 32nd Army Tank Brigade would attack south and take the Sidra Ridge. Following those movements, timed to happen sequentially, the 7th Armoured Division and 9th Indian Brigade would attack west into the Cauldron. Why could they have not been more concentrated and moved together? This was all to commence on 5 June 1942. This is based on the account in Vol.III of the Official History.
