In the early months, chaos and lack of direction immobilized the government. On the military front, the security forces did not know how to fight an enemy moving freely in the jungle and enjoying support from the Chinese rural population. British planters and miners, who bore the brunt of the communist attacks, began to talk about government incompetence and being betrayed by Whitehall. The initial government strategy was primarily to guard important economic targets, such as mines and plantation estates. Later, in April 1950, General Sir Harold Briggs, the British Army's Director of Operations was appointed to Malaya. The central tenet of the Briggs Plan was that the best way to defeat an insurgency, such as the government was facing, was to cut the insurgents off from their supporters amongst the population. The Briggs plan also recognised the inhospitable nature of the Malayan jungle. A major part of the strategy involved targeting the MNLA food supply, which Briggs recognised came from three main sources: camps within the Malayan jungle where land was cleared to provide food, aboriginal jungle dwellers who could supply the MNLA with food gathered within the jungle, and the MNLA supporters within the 'squatter' communities on the edge of the jungle.
