The early 1960s was the time when cheap transistor radios first became available. This new medium was used to great effect by Nasser, who promoted his nationalist message over the airwaves via the Egyptian wireless station, “Voice of the Arabs.” This message reached all parts of South Arabia, so that even the most primitive and isolated tribesman now had access to anti-British propaganda. The Radfan again became the focus of dissident attacks and in April 1964, the British High Commissioner had to admit that “The Aden-Dhala Road is again unusable as the area is now under guerrilla control.” In an attempt to crush the dissidents and drive them out of the Radfan, the Commander Aden Garrison, Brigadier Louis Hargroves, swiftly put together a brigade-size force.
