In 1960, Britain decided to withdraw from Aden, which was then part of the Federation of South Arabia, with independence scheduled for 1968. This decision started a campaign by the local tribes against the regular army. Supported by Egypt, communist infiltration reached a head in 1963 when Britain was forced to take action in support of the local government in what was called the Aden Emergency. The British force, known as Radforce, comprised a mixture of troops including a company from the 3rd Battalion. The rest of the 3rd Battalion, under the command of Lieutenant-Colonel Anthony Farrar-Hockley, was also sent to Aden to conduct operations in the Radfan mountains, capturing the Bkri ridge in May 1964. Farrar-Hockley was awarded the bar for his Distinguished Service Order (DSO) for this operation. The rest of the battalion were awarded two Military Crosses (MC) and one Military Medal (MM), and a number were mentioned in dispatches. By 1964, the terrorist attacks had spread to Aden, south of Radfan; to protect British servicemen and their dependents, the 1st Battalion was deployed on security duties throughout the areas of Crater and Khormasker. In January 1967, the 1st Battalion returned to Aden on an emergency tour to cover the final withdrawal of British troops from the region. For a series of actions in June in the Sheik Othman and Al Mansura districts of Aden, the battalion's commanding officer, Lieutenant-Colonel Michael J. H. Walsh, was awarded the DSO. The rest of the battalion were awarded three MCs and one MM, and a number were mentioned in dispatches.
