General Wilson's strategy for the attack on Syria and Lebanon

The Australian Official History says that by dividing his force into three columns for the attack on Syria and Lebanon, General Wilson assured thatnone of the attacks would have overwhelming strength to achieve a major success. We don't understand why General Wilson was put in charge, except that he was a favorite of Churchill for reasons that we have not yet understood. General Wilson also had bought into the idea that the Vichy French would collapse when attacked, which was not the case. They had a history with Churchill, since at least the attack on Mers el Kebir in July 1940, and they were ready to resist any attempt to occupy Syria and Lebanon. In retrospect, a strong resistance should have been expected, but there were politics involved that kept leaders from thinking clearly. A multi-front attack was appropriate if there had been a real possibility that the defenders would collapse when attacked, but that was very unlikely. This is based on the account in Vol.II of the Australian Official History.
