Part 4
Section LIX: — Comparison of Forces.
600. Navy.—The Japanese were able to operate with a balanced Fleet based on Camranh Bay in French Indo-China. In the battleship "Prince of Wales" we had a more powerful unit than anything the Japanese possessed but we never had a balanced Fleet. The loss of the "Prince of Wales" and "Repulse" left the Japanese in undisputed possession of the eastern approaches to Malaya.
Malaya had a coast line of 1,000 miles with innumerable creaks. To conduct the attack or defence of such a country actively it is essential to be able to undertake water-borne operations on an appreciable scale. In this form of war fare also the Japanese established a superiority, partly by the introduction of a large number of their special military landing craft, partly by the clever use of local craft, and partly by the degree of air protection which they were able to give to their coast-wise shipping. On our side we had three destroyers, three river gun-goats, a few Fairmile motor launches and some converted motor craft, but the latter were slow, unarmoured, lightly armed and very vulnerable to air attack. Our local craft had little air cover.
601. Army: — The initial Japanese landings in South Thailand and Malaya were made by the equivalent of two divisions and one tank regiment. A few days later a division of the Japanese Imperial Guards arrived in South Thailand by train from the north. There are indications that a fourth division may have arrived later in December, while a second tank regiment arrived either in December or January. In the middle of January two fresh divisions landed at Singora in South Thailand. It appears that it was originally intended to employ these divisions for an attack on the east coast of Johore, but as a result of a change of plan they were moved forward by motor transport to the Kluang area in Central Johore. They were in reserve for the attack on Singapore Island.
It appears, therefore, that the Japanese employed five and perhaps six divisions and two tank regiments for the attack on Malaya. As they kept the same divisions in front line for prolonged periods, during which they were known to have suffered heavy casualties, it is probable also that they filled up these divisions with reinforcements. In addition to the above, they had Army, Base and Lines of Communication units. The establishment of these would no doubt be smaller than in the British Army.
On the basis of 20,000 men per division and 150 tanks per regiment, I estimate that the Japanese employed a minimum of 150,000 men and 300 tanks in the Malayan campaign.
602. Against this we had on the outbreak of hostilities the equivalent of 3.5 divisions with Fixed and Anti-Aircraft Defences but no tanks. Later we received as reinforcements about the equivalent of another two divisions and one squadron of obsolescent light tanks. The total number of officers and men who took part in the campaign on the British side was a little over 125,000, though the strength in Malaya at any one time was considerably less than this. This number included a high proportion of Command, Base and Lines of Communication troops, many of whom belonged to non-combatant units or were unarmed owing to shortage of personal weapons.
603. The initial attack on Singapore Island was carried out by three Japanese divisions. There were two and possibly three divisions in reserve. Two of the reserve divisions had recently arrived in Malaya and it may be assumed that they were at full strength. Some of the others may have been at less than full strength. On this basis I estimate that there were at the cessation of hostilities a minimum of 100,000 Japanese troops on Singapore Island or in South Malaya. How many of these had actually crossed to the Island and how many were on the mainland is not known nor is it very material, but there is evidence to show that at least 23,000 crossed on the first day of the attack. There were also a minimum of 175 Japanese medium and light tanks on Singapore Island at the cessation of hostilities.
The total of the British forces in the Singapore Fortress area at the same time was in the neighbourhood of 85,000. This figure included a large number of non-combatant troops, i.e., Medical Services, Pioneer and Labour units, etc., of troops for whom no arms were available owing to a general shortage of personal weapons, and of sick and wounded. Probably about 70,000 of these men were armed and equipped but many of them be longed to Base and other administrative units and were very inadequately trained. There was one squadron of obsolescent light tanks.
The Japanese had an advantage in the fact that a high proportion of their forces in South Malaya and on Singapore Island were fully trained combatant troops, most of their Base and Lines of Communication troops being further north.
604. In official statements made in this country and recently published in the world Press, figures very different from the above have been given. In fairness to the officers and men who fought in Malaya I ask that those statements may now be corrected.
605. Air.—There is evidence to show that on the 11th December, 1941, i.e., three days after the outbreak of hostilities, the Japanese had 124 aircraft in Thailand and 280 in Indo-China. It may be assumed that in round numbers about 300 of these were being employed against Malaya. They included twin-engined bombers, dive-bombers, torpedo-bombers and fighters. The range of the fighters had been greatly increased by the use of auxiliary petrol tanks.
Opposed to this our Air Force had on the outbreak of war a total of 141 operationally serviceable I.E. aircraft, with a few light air craft (Moths, etc.) manned by the Volunteer Air Force. Few of these aircraft were of modern types and a number were obsolescent. There were no long-range bombers or long-range fighters, no dive-bombers, no transport or military communication aircraft and no special army co-operation aircraft. The striking force was weak, the fighters were not of the most modern type, the reconnaissance forces were inadequate and the torpedo-bombers were slow and out-of-date.
During the operations we received reinforcements of 31 aircraft from the Netherlands East Indies, some bomber and reconnaissance aircraft from the U.K. and the Middle East, and the equivalent of three squadrons of Hurricane fighters.
These, however, were never more than sufficient to replace casualties and the strength of our Air Force dwindled progressively through out the campaign.
What reinforcements the Japanese received is not known but shortly after the cessation of hostilities they were reported to have had 258 aircraft in South Thailand and Malaya and 270 in Indo-China. At the cessation of hostilities there were no British aircraft in Malaya.
