1st March, 1964
Enemy activity in Sematan-Lundu area. At Kampong Sekati, which is a 20-minute walk to the west of Lundu and 14 kilometres from the border and consists of a few scattered houses mainly inhabited by Chinese, a search patrol going through the kampong on 1st March found a collection of arms and ammunition hidden in thick undergrowth on the outskirts of the kampong. The arms consisted of two rifles, two sub-machine guns, 805 rounds of ammunition, three grenades plus uniforms and a pack. The weapons were in good condilion and had been placed there not more than three days previously. They were found 200 yards away from the house of a Chinese who is suspected of being an Indonesian supporter, and has since been arrested. One hundred yards from this house a newly dug trench was found. It was obviously being prepared as a hiding place for the weapons.

In the pack a letter written in Chinese was discovered addressed to Chin Kim Yit who is one of the sons of the arrested house owner. Kim Yit is told in the letter that whether he is in Indonesia or Sarawak he is to fight a life and death battle against the enemy. The identity of the writer was concealed. Interrogation of the father revealed that his son Kim Yit returned to Sarawak from Indonesia with a small party of two lndonesians and one other Sarawak Chinese on 25 February, all of whom were Indonesian Irregulars. The father’s three sons have all been missing from home for some months. He admitted that when Kim Yit and his party arrived he fed them and that he was told by them that they had all come from Indonesia having been trained at Singkawang and subsequently ordered to enter Sarawak to attack Security Force positions.

6th March, 1964
A Security Force patrol just to the north of Pangkalam Setungkot which is eight kilomctres north-west of Lundu made contact with a group of enemy at 3.30 p.m. on 6 March. About 30 to 40 enemy in uniforms were in a clearing in the jungle just off the main track. Some of them had removed their jungle boots and appeared to have been having a short rest or food halt. When Security Forces opened fire the enemy ran away and were quickly lost in the deep jungle, leaving behind one seriously wounded Javanese and a large quantity of equipment which includes a 50 mm mortar with bombs, 2 rifles, a pistol, a military type radio transceiver No. 3274, a hand generator Serial No. 1227/43, three yellow dropping zone markers, which are used to indicate a supply area when resupply by aircraft is being carried out, several pairs of jungle boots, and some clothing.

The wounded Javanese was one Abdul Hamid bin Seman. Due to the seriousness of his wound only limited interrogation has so far been possible; he was taken to hospital. Some of the mortar bombs are clearly marked with the Tndoncsian Ordnance factory marking of a star and the letters PSM. Some of the personal equipment such as packs and mess tins are marked with the number ‘328’. 328 being known as the number of the lndonesian Raider Battalion opposite First Division. The enormous quantity of military equipment captured which is almost one ton in weight, could only be of value to a military type organisation.

6th March,1964
Euemy Activity in the Pantu Area. Pantu is a small town in Second Division 40 kilometres west of Simanggang. Four kilometres to the south runs the main road between Kuching and Simanggang. At this point the road is only two kilometrcs north of the Indonesian border. The
border in this area is a range of hills the northern slopes of which lie within the Sarawak territory. There is little jungle and the hillside is covered with rocks and out-croppings which overlook the road.

On 6 March two platoons of Malaysian Security Forces were moving along the road when they were fired at from the hillside within Sarawak territory. Although the enemy occupied a strong defensive position the Security Forces attacked suffering three killed and two wounded. After a 40-minute battle the enemy withdrew to Indonesia. Enemy casualties are not known but several blood trails were found leading back to the border. The enemy were between 30 to 40 strong. A search of the arca resulted in the following equipment being recovered:
(a) One military radio set Serial No. 3278 complete with hand set, rod and
line aerial made by BBC Ltd. of High Wycombe, England.
(b) One hand generator Serial No. 1168/485 complete with tripod made by
BBC Ltd. Neasden Lane, London, N.W.lO.
(c) Some camouflage uniform bearing 328 Siliwangi Kudjang 11 flashes.
(d) 7 hand grenades.
(e) 8 50 mm mortar bombs.
(f) 445 rounds of ammunition of lndonesian and United States manufacture.

Little attempt was made to hide the identity of 328 Raider Battalion which is an Indonesian Regular Unit. They wore the camouflage uniforms sometimes worn by Indonesian Regulars but not worn by Irregulars. The radio set captured is of the same type as that captured in the Sematan area on 6 March and works on the same frequencies. Security Forces listened in on the frequency on which the set had been tuned. About an hour after the incident a message was intercepted to the effect that the enemy was returning with dead and wounded. In reply an unidentified station stated that a small reverse of that sort was of little consequence as there were plenty more Indonesians where those (the casualties) had come from.
