This Day in History: 1919-05-02

The 3^rd Afghan War had began with the incursion by Afghan forces across the border and onwards to the Khyber Pass. As a consequence the 2^nd Battalion mobilised and marched to Khirgi, eventually to picquet the Zam River and then to establish picquet posts on both sides of the high road. This tactic was the forerunner of the permanent picquet system which was adopted in all subsequent operations.
