Through World War II, Killed in action and Junk (ship)

Allied soldiers, under the command of Major General Gordon Bennett, inflicted severe losses on Japanese forces at the Gemensah Bridge ambush and in a second battle a few kilometres north of the town of Gemas. Members of the Australian 8th Division killed an estimated 600 personnel from the Japanese 5th Division, in the ambush at the bridge itself, whilst Australian anti-tank guns destroyed several Japanese tanks in the battle north of Gemas. The battle saw the heaviest Japanese losses of any battle the Japanese had fought in the Malayan campaign and saw the death of one of their commanders Shiegeo Gotanda who was killed by Australian fire while directing his troops, temporarily shattering the morale of many Japanese soldiers.

Although the ambush was successful for the Allies, the defence of Muar and Bakri on the west coast was a complete failure which resulted in the near-annihilation of the 45th Indian Infantry Brigade and heavy casualties for its two attached Australian infantry battalions. This was the first engagement between units of the British 18th Division and Japanese forces in Malaya.

Prelude

The ambush was ordered by the head of Malaya Command, Lieutenant General Arthur Percival's own instructions; he strongly felt that ambush was the way to fight the Japanese. A multinational force under Bennett, codenamed Westforce, was assigned to defend the Muar area. Westforce took up positions covering the front from the mountains to the shore of the Malacca Straits. There were two main areas, and both of these were sub-divided into sectors, which were themselves widely separated and linked with each other chiefly by rather tenuous signal communications.

Gemas positions

The first area was around the central trunk road and the railway beyond Segamat. The three subordinate sectors were:

  • (a) Astride both road and railway near Gemas. Here, the 8th Indian Infantry Brigade made up the holding force.
  • (b) Further forward along the same road lay the 27th Australian Brigade. They were charged with a counter-offensive role, and had already prepared an advanced ambush, from the 2/29th Australian Infantry Battalion, for the Japanese several kilometres ahead at the Gemensah Bridge.
  • (c) Leftwards was the 22nd Indian Infantry Brigade tasked with guarding the approaches to Segamat from Malacca, which skirt either side of Mount Ophir.

Gemensah Bridge positions

B Company of the 2/30th Australian Battalion, under Captain Desmond J. Duffy, entrenched and concealed themselves on one side of the Gemensah Bridge, spanning a stream, as part of the ambush. The bridge itself had been mined with explosives, and a battery of field artillery sited on higher ground behind the infantry whence it could command the Japanese approach to the bridge. The 2/30th Australian Battalion was under the command of Lieutenant Colonel Frederick Galleghan, nicknamed "Black Jack".

For the Japanese side, the Mukaide Force (commanded by Colonel Mukaida) was created to take the lead from the tired Japanese 5th Division and was approaching Gemas and the Australian ambush at Gemensah Bridge. Mukaide Force consisted initially of the 1st Tank Regiment with an infantry battalion and artillery for support under the command of the 9th Brigade. It was reinforced by the 11th Infantry Regiment on 15 January. Colonel Mukaida was the commander of the 1st Tank Regiment, which at the beginning of the Malayan Campaign, consisted of 31 Type 97 Chi-Ha and 17 Type 95 Ha-Gō tanks.

Muar positions

The second area was that which covered the West Coast and the roads which run along it to the Johore Strait. This had two sectors, actually more in line with one another than those of the first area, but even less effectively in touch. The defence of this area was assigned to the 45th Indian Brigade, reinforced by a single battery of field artillery. It included the seaport of Muar, and stretched some 50 km (30 mi) up into the jungle towards Segamat, along the winding course of the Muar River, with its deep-wooded, creeper-covered banks. Under orders from General Bennett, two of the battalions were disposed along the river line, which they thus divided between them, while the third went into active reserve near the coast.

The Imperial Guards Division was moving down the west coast of Malaya, with a battalion sized force under the command of Col Masakazu Ogaki approaching the Muar river area from the sea, while the 4th and 5th Guards Regiments approached Muar from the north under General Nishimura.

The newly arrived 53rd Infantry Brigade of the British 18th Division formed part of Westforce. The brigade included the 2nd Cambridgeshire Regiment, 5th Norfolk and 6th Norfolk Battalions. Although Percival gave the order to deploy them, they were unfit for immediate employment, having been at sea for 11 weeks.
