Below is an extract from the War Diary covering the period between 23 Sep 45 to 28 Sep 45.

It covers the move to Kota Waringin for the purpose of accepting the surrender and

Transporting of Japanese forces for processing at Banjarmasin.  

The Kota Waringin area is approx 450km to the west of Banjarmasin. The journey took just over 24 hrs to complete

Because of Navigation concerns they spent the night of 24/25 anchored (with the HAPGOAN, the coastal vessel that was to transport the Japanese) at the mouth of the river before going upstream to Kumai on 25 Sep. At Kumai, the village headman reported that majority of the Japanese had been assembled 1km north of Kumai.

–

 

A number of Japanese Officars (4 Naval and 1 Army) presented themselves to Lt Lewis at the Kumai wharf. Lt IIzuka reported that 153 soldiers and 18 Civilians  were in their party north of Kumai, 9 of whom were hospital cases suffering from (2 x appendicitis, 6 Malaria and 1 a Violent Lunatic). Weapons were centralised and stored. The OC of their sub unit Sub-Lt Takare had previously committed Hari Kari. Lt Lewis was able to inspect and confirm these reported numbers.

–

All Japanese were moved to the wharf and placed under guard. Lt Iizuka was given a warning order that they were to be moved to BANJARMASIN on 26 Sep. An English speaking Chinese was interrogated. Report shown below.

Arrangements were made for meeting with the Sultan in PANGKALAN BUN.

–

Travelled to PANGKALAN BUN by car (approx 15KM via road) to Sultans palace.

Lt Lewis was received by the Sultan at a civic reception at his Palace. The civil administration was 

returned to the Sultan whose position had been eroded during the Japanese occupation.

The Sultan returned with Lt Lewis to Kumai to be briefed on the stores and supplies that were to be policed.

The Japanese and one of their local collaborators (Hadji Mochamad Kasim) were loaded on the vessels.

Both boats (the “HMAML Q 1359” and the coastal vessel “Hapgoan”) set sail for Banjarmasin on 26th Sep at1555hrs.

Arrival in Banjarmasin was two days later.

The above list is the weapons and equipment handed over by the Japanese. A number of rifles and LMGs most of which were dumpted at sea. The Dutch captured weapons were returned to the Dutch.

The Japanese swords were returned to the Bn store. 

Equipment included Diesel and Petrol engines, Generators for lighting and radio equipment, workshop equipment (lathe drills, saws, grinding wheel, etc) and 10 vehicles of various types.

Most of this equipment was left to be policed by the Sultan’s men.

Document F is a Patrol Report

The patrol was to ascertain whether and large numbers of Japanese were in the area and to locate any Japanese weapons.

It was determined that no large numbers of Japanese were in the area and that all former store houses were

searched but no weapons were found. Weapons previously founded were handed to a patrol from C Coy.

Document C is an Interrogation Report

This report is from the interrogation of an English speaking Chinese concerning the man Hadji Mochamad Kalim who was brought back from Kumai to Banjarmasin on the Naval vessel. Kalim was named as a Japanese collaborator. He had lived in the Kumai area since 1936 There were two occasions where Kalim received a token punishment from the Japanese for trying to buy a radio and for fishing. The same offences perpetrated by others would result in much harsher punishment.

In 1942 There were 1000 British and Dutch troops in the area but these had subsequently been transferred to Banjarmasin. since then there were not many Japanese in the area until they built an airstrip 6 months before the end of the war. The factory and equipment at Kumai was used in the manufacture of swords and in support of the air strip operations.

Below is the report from the Chinese person in his own handwriting.
