were not bringing the results that they hoped for. Chin Peng estimated it would be a year or two before the British took actions against the CPM, leaving them ample time to prepare for a guerrilla war. On 12 June 1948, the colonial government outlawed the burgeoning trade union federations amid a rising atmosphere of tension. Since then, there was no reduction in the level of violent activities, other than the neutralisation of trade unions. Political murders of informers, anyone found to be working against the labour movement or the CPM, non-Europeans considered enemies to the communist cause or strike-breakers who used thugs and gangsters to harass protesters rose. The murder of three Kuomintang leaders in Johor on 12 June had convinced the British that the communists were escalating the conflict in retaliation for outlawing the trade unions, while in the CPM's eyes these murders were just purely acts of intimidation. Chin again claimed that he was not aware of the murders at the time, although he approved of the later killing of the plantation managers who he claimed were harsh and cruel towards farmworkers. The Emergency (1948–1989) On 16 June 1948, three European plantation managers were murdered in Sungai Siput, which has generally been identified as the incident contributing to the Malayan colonial administration declaration of a state of emergency. Rather, Sze-Chieh Ng argued these murders were merely the final catalyst for a long-brewing crisis that had been going on since the trade unions began agitating in 1945. Historian Anthony Short feels that this was more of a panic reaction than a carefully considered move. According to him, the government had been powerless to deal with the unrest plaguing Malaya since 1945. According to Purcell's viewpoint, the Emergency was declared in response to increasing incidents of violence and lawlessness. Many Singaporean historians and anti-communists allege that Chin Peng ordered the killings. Chin claimed he had no prior knowledge of the plot. He added that he barely escaped arrest, losing his passport in the process, and he lost touch with the Party for a couple of days. Chin became the most wanted man of the British government, with the government offering a reward of $250,000 for his capture. On 17 July 1948, CPM offices in Kuala Lumpur, Ipoh, Singapore, and other major cities were raided, followed by mass arrests of suspected communists and anti-government individuals on 21 July. The CPM
