The Communists fled rather than confront the deadly little Nepalese, who were not in fact present.

Luck played its part in the early death of Lau Yew, Chin Peng’s right-hand man. Former navy stoker Police Superintendent Bill ‘Two-Gun’ Stafford, so called because he carried a revolver under each armpit, learned from his barber-informant in Kuala Lumpur that the Communists were to hold a meeting in a village south of the capital. Stafford and a team of Chinese detectives lay in wait, but were spotted by three men who exited a hut firing wildly. Two of them were shot dead and the third mortally wounded. After identifying the body of Lau Yew, Stafford and his men handcuffed five women, including Lau Yew’s wife. Attacked in turn by a large number of insurgents, Stafford earned his Chinese nickname ‘Iron Broom’ by charging the attackers shouting ‘Here come the Gurkhas!’ The Communists fled rather than confront the deadly little Nepalese, who were not in fact present. Stafford was also responsible for a huge haul of Communist weapons, acting on a tip-off from an informer eager for the reward posted for every gun or bullet. The two men met in the back row of a dingy cinema showing a Tarzan movie. The next night Stafford and four men went to a lonely spot near the village of Karang, where after strenuous digging they unearthed a cache which included dozens of machine guns, 237 rifles and 10,000 rounds of ammunition. The informer was due M$100,000 for this haul, but eventually settled for M$60,000. Stafford stoutly refused an offer of a share in the proceeds.
