In 1921, Lieutenant-Colonel Frederick Gerald Peake formed the Arab Legion as a police force in the former British protectorate of Transjordan. The Legion’s main roles were to keep order among Transjordian tribes and safeguard the villagers from Bedouins. In subsequent years, under the leadership of Glubb Pasha, the Arab Legion was transformed into the best-trained of all Arab armies. This richly illustrated book examines the history of the Arab Legion, detailing the infantry, supporting arms and services, and air, sea, police and national guard forces. It also profiles leaders, like Pasha, who were influential in the evolution of this force.
