12 January 1942. Borneo
Singkawang II airfield now hosted not only the 750 strong Dutch garrison but had been more than doubled with the arrival of the best part of the two Indian Battalions (3/16th and 5/14th Punjab Regiments) that had been defending Kuching. Word had reached the Dutch commander that the island of Tarakan had fallen to the Japanese, but that the oil wells had been destroyed beforehand.
Direct contact with the other Indian Battalion (2/15th Punjab Regiment) had been lost. The latest message from Singapore was that Colonel Lane’s force was still resisting but running short of rations and ammunition. Since they were under General Percival’s command, his orders had been to withdraw towards Jesseltown. After that it wasn’t clear what would happen to them.
The fact that the Japanese had invaded the Dutch East Indies, once again aiming for an oil producing area, had given the senior commanders in the area a clue as to Japanese intentions. There were obvious objectives, not just the oil. Their attacks tended to be looking for airfields, and so far, in Malaya and Borneo, these airfields provided air support for the next phase, taking another resource rich area, with air-power giving their fleet and transport the cover needed to leapfrog from one objective to the next. The Japanese obviously had enough strength to capture Menado on Celebes the same day as on Tarakan. The use of paratroopers came as a surprise that brought back memories of the fall of the Netherlands in 1940.
From his Headquarters in Java, Hein Ter Poortan, Commander-in-Chief of Netherlands East Indies forces looked at the map of Borneo and recognised that Balikpapan was likely to be the next objective. While Menado didn’t have oil, the airfields there was obviously the main target. That being the case, then Kendari would have to be considered as the next Japanese objective on Celebes. Ter Poortan wasn’t entirely when these movements would happen, but he thought it likely to be around two weeks, probably a bit less. Consulting with Vice-Admiral Conrad Helfrich (CO Zeemacht Nederlands-Indië (Royal Dutch Navy)) and the American Admiral Thomas Hart, Ter Poortan wanted a plan to intercept the Japanese fleets and sink them. It didn’t take long to identify the problems. The Makassar Strait (Tarakan, Balikpapan) and the Molucca Passage (Celebes) would need two separate naval forces, unless a combined fleet could act effectively in one, then the other.
The Dutch and American naval staffs, along with their British and Australian allies attempted to put together a strong enough force, with submarines and aircraft for reconnaissance, and air cover for the ships.
Ter Poortan focussed next on the defences of Balikpapan and Kendari. Major-General Ludolph Oyen, (CO Militaire Luchtvaart, KNIL (Air Force)) was requested to do what he could to hamper the Japanese use of Tarakan’s airfield. Oyen knew that it wasn’t a very well developed facility, and that making it difficult to be used was something that his limited forces might be able to achieve. Oyen began plans to organise as many bombers as he could to concentrate, using some of the airbases on Borneo that had been built for that very purpose. Hitting the airfields at Menado would be problematic, but he knew defending Kendari would be crucial. Oyen would have his work cut out to do so. He asked if he could strip some of his units from Java and Sumatra to defend Borneo and Celebes. Ter Poorten and the Civilian Governor, Van Starkenborgh disagreed over this, but as head of the armed forces, Ter Poorten gave Oyen permission to concentrate his force to fulfil the mission required.
On Borneo, now that Tarakan had fallen, the Koninklijk Nederlands Indisch Leger (KNIL Army) only had two Battalions available. One was based at Pontianak, the other, over a thousand strong, defended Balikpapan. Getting reinforcements to Balikpapan in time would be a problem, and the only large enough professional force on Borneo were the Indian Battalions at Singkawang II. From there, they would need to move to the coast at Pontianak, then be shipped to Balikpapan, a dangerous venture at this time. Ter Poorten had consulted Lt General Percival who agreed that if the Dutch could do it, then acting Brigadier Henry Moorehead would come under Ter Poorten’s direct command.
Another alternative was to do the same with the KNIL Army as with the KNIL Air Force. So far, the local defensive units at Tarakan and Menado had proven too small and isolated to fulfil their task. By putting a larger force together that could go toe to toe with the Japanese risked them being by-passed, but seeing something of the Japanese methodology, it was possibly a risk worth taking. Running down the list of assets Ter Poorten identified at Surabaya a Marine Battalion and 6th Regiment KNIL in addition to the Surabaya Garrison Regiment. If these could be moved to Kendari, it would give the Battalion there a real chance to resist.
Looking at the notes, Ter Poorten saw an addendum. Calling one of the staff to ask about it, he was informed that some Americans had arrived at Surabaya the day before. Originally bound for the Philippines, the 2nd Artillery Battalion of 131st American Field Artillery Regiment of the Texas National Guard was currently unattached. The fact that the Americans had their artillery and ammunition with them was a bonus. Whether Ter Poorten could get them under his command and sent to Kendari was something he’d need the Americans to agree to and he immediately got in contact with Admiral Hart, the senior American officer in the Dutch East Indies, who told him he’d find out and get back to him.
Ter Poorten realised he was in a race against time. To increase his forces at Balikpapan and Kendari before the Japanese got there would hopefully slow the Japanese. If the allied navies could knock out one of the Japanese invasion fleets, that would hamper the enemy further. If the air force could make it more difficult for the Japanese to have control of the air, that would be even better. There were a lot of ‘ifs’ in that thought. Ter Poorten had to do something to regain some initiative, otherwise the Japanese would just overrun his home one airfield at a time.
