On 24 January, 1964, Security Forces while patrolling in the jungles near Serudong, made contact with an armed and uniformed enemy party. This party was part of the group who were lost in this area, and part of the group mentioned in serial one. A fire fight developed which lasted a few minutes when the enemy party disengaged and fled southwards, leaving behind one enemy killed, one captured and three surrendering. There were no Security Force casualties. The enemy casualties were immediately sent to Tawau for identification and questioning by the authorities.

Also on this same day a second patrol of Security Forces made contact with two more enemy near this area. There were no casualties and the enemy fled in a south-westerly direction. Later during the day in this same area a third security force patrol following up an enemy track leading south-west made contact with three uniformed and armed enemy.

Indon Enemy Activity in the Long Pasia Area
Long Pasia is a small town of a few hundred people in the Interior Residency of Sabah. It lies approximately seven kilometres from Sarawak, Fifth Division, and ten kilometres from the Indonesian border, The river Padas runs through this town northwards starting from the mountain ranges of the international border. This town is surrounded by jungle. Across the border and about 30 kilometres from it is the Indonesian town of Long Bawan. It is known that an Indonesian Army garrison consisting of two infantry companies of the Indonesian Army, a small unit of Indonesian paratroopers together with a force of Indonesian regulars are stationed there.

On 22 January a Security Force patrol on operations in the jungle area south of Long Pasia found tracks for about 20 men moving north towards Long Pasia. These tracks were followed by the Security Forces who on the next day found two enemy camps 30 yards apart about six kilometres south of Long Pasia on the river of the Sungei Padas. Evidence found in this located camp indicated that it accommodated about 60 people and this camp had been lived in for about two days immediately before the discovery. Tracks from this camp led northwards following the Sungei Padas towards Long Pasia.

24 lunuary, 1964
In the early hours of 24 January another Security Force patrol of about 36 men was sent from Long Pasia into this area. In the afternoon of this same day, this fighting patrol met with an enemy group of about 40 men near Kampong Miau (just about two kilometres south of Long Pasia). Fire was immediately exchanged by both sides which lasted for about ten minutes. This incident resulted in seven enemy killed and there were no casualties to the Security Force platoon. The remaining enemy equipment, weapons and ammunition was recovered.

Also captured were important enemy documents which gave a breakdown of this particular enemy force that had made incursions into the Interior Residency of Sabah. Documents also show that this enemy force was heading for the coastal region of Fifth Division, Sarawak. On reaching the coastal regions, this enemy force was to recruit, organise and train local dissidents, distribute subversive literature and organise a subversive campaign against the government. Alternatively, this force was to go to Brunei, but if Security Force operations were too stiff then they were to return to Kalimantan.

Captured enemy documents also revealed that this force, 58 strong, were trained by 609 Battalion of the Tndonesian Army at Malinnu who also sponsored their trip to Long Bawan. This force received training in the use of grenades and particular attention was laid on night firing. The leader of this group is Omar, With Omar on this expedition were his two brothers, Bosma and Hassan, who were helping out as guides. A list of all equipment, arms and were ammunition recovered.

Immediate Security Force follow-up operations resulted in two more enemy being captured and two enemy surrendering. One of them was Marimin bin Arjo. His interrogation revealed the system by which ‘Volunteers’ were recruited, on pains of imprisonment for reprisal and how they were given military training.
