The incident started just before dawn with the Communist gunmen launching a guerrilla assault on the police station leading to the deaths of almost all of the police officers stationed there. When they began the siege, the attackers strongly believed that they would be able to defeat the policemen and gain control of the police station within a short span of time. This was due to several factors in their favour: their arms and numerical superiority and the relative isolation of the station. The battle began at about 4:15 am.
