5. It was for this reason that the passage of reinforcements to Singapore was a matter of such paramount importance. We were unexpectedly successful in getting the troop convoys through practically unmolested until the very end. As, however, our forces in Malaya showed no signs of being able to check the enemy advance seriously, I pressed the military authorities for confirmation, in the case of the later convoys for which I was responsible, that the troops should actually proceed to Singapore and not be diverted to N.E.I. It was always possible to divert the convoys at sea in case of a late change in the plan. On every occasion the General Officers Commanding Malaya was in favour of getting troops to Singapore. The wisdom of this seemed doubtful, especially in the case of R.A.F. personnel and A.A. troops, some of whom were in fact immediately back loaded to N.E.I. on their arrival.
6. The last convoy, BM 12, with reinforcements for the 9th and 11th Indian Divisions and Divisional Troops of the 18th Division, was the only one which suffered appreciably from enemy attack, and that was not until it was in the approaches to Singapore.
Though the actual troop casualties in this attack were not heavy, the moral effect was inevitably great and it is doubtful whether any of the troops in this convoy were of much value in the remaining ten days of the defence of Singapore.
7. It is surprising that the enemy did not devote a proportion of this surface forces and long range bomber strength to attack our convoys between Sunda Straits and Singapore.
In the confined waters of the Banka Straits, with an escort inadequately armed again air attack, and with only the slenderest prospect of fighter cover, it would seem that at any time after the middle of January when the enemy had aerodromes available in Southern Malaya and Borneo, convoys could easily been located by daily reconnaissance and a most damaging attack could have been launched, which would in all probability have stopped further reinforcements, and facilitated the Japanese task considerably.
8. During the last fortnight of the defense of Singapore the passage between there and Batavia became more and more hazardous for the ships of the China Force, but they stuck manfully to their task, which culminated in the heavy and continuous Japanese air attacks on 12th – 15th February on the ships and vessels escaping from Singapore.
