Recently declassified British files also show that Abdul Aziz was aware and tacitly agreed to launch his own assaults on his adversaries, the Rasheedi family, who were under Turkish over lordship when the invasion of Palestine was to be commenced.
In this manner, cities like Hail were attacked and besieged through British orders, even when Abdul Aziz preferred other cities. The reality he was he had to obey without question, as long as he wanted British arms and support.
The issue here was that Palestine was to be removed from Muslim control and placed under the Kufaar and he agreed- by attacking those cities and towns in what is now Saudi Arabia only when given the orders to do so to allow the British to successfully invade Palestine.
Other declassified files confirm the words and declaration of Waleed Ibn Talal, a member of the Saudi royal family, that his famous grandfather, Abdul Aziz, came to the throne, not by virtue of popularity, his vision, the promise of Shariah legislation, but through British patronage alone.
