Extract from Marianne and John by Charles Montague, ch.13
With the Japanese now enjoying air and naval superiority, the course of events in Indochina could hardly now alter. Having consolidated the north, the IJA pushed south along the coast, their 5th Division leading, repeatedly outflanking French positions either by inland movements or by small-scale amphibious operations. General Georges fought a skilful delaying action, avoiding encirclements, but lacked the strength to hold any line. Admiral Esteva begged the British to interfere with the Japanese amphibious attacks, but Cunningham refused to bring his main forces within range of Japanese land-based air, not to mention potential intervention by the heavy carriers of the Combined Fleet. Instead he sent his T-class submarines and a destroyer flotilla, and together with the remaining French ships they imposed some attrition and delay; but they too suffered painful losses, with three RN destroyers lost in January and three more in early February, all to air attack. ‘The Jap dive-bombers sank the poor Defender in five minutes,’ commented Cunningham. ‘Most of our other ships wouldn’t last much longer. I constantly make the point that we are weaker, so must maintain a fleet in being strategy.’
General Wavell protected his naval chief from incessant demands from London for more decisive action. ‘The enemy retains the initiative in the Indochina area,’ noted Wavell, ‘we cannot keep our ships on station constantly, and as soon as they withdraw they mount another of these amphibious operations. Besides they are just as adept at flanking through the hills and jungle.’
Once Vinh fell (mid-January), the Japanese sent one division across the mountains into Laos and this too pushed south, though more slowly, and French forces stood firm at Pakse and inflicted a small but severe reverse on them in February. However, by this time the Imperial Guards under the formidable General Yamashita had pushed south past Da Nang and gained airbases within range of Cam Ranh, forcing its abandonment by the remaining French naval forces. These now all withdrew to Singapore.
At this point XL Corps under General Slim entered the fray with British 18th and Indian 4th Divisions. ‘It may already be too late,’ wrote Wavell, ‘but at least we are getting into action now.’ Slim tried to hold a line at Pleiku, but faced the same problems as the French, chiefly the enemy’s air superiority and the flanking movements enabled by this. The RAF squadrons which entered the battle quickly suffered terrible attrition.
In late February Saigon itself came within range of enemy aircraft. The British had now sent 32nd Army Tank Brigade and these proved invaluable in extricating troops from Japanese encirclements, but could not stop the rot. The Japanese now also resumed their offensive in the Mekong valley and pushed into Cambodia…
The Council ordered the Governor to leave on February 28th. The few surviving serviceable RAF aircraft - less than twenty out of ten squadrons sent - flew out the same day, soon followed by the handful of remaining French aircraft. General Slim’s chief concern now lay in extricating what forces he could. Japanese forces were now racing for both Saigon and Phnom Penh. ‘Evacuation by sea not contemplated,’ wrote Wavell to the Council, ‘as this crisis coincides with the crisis in Borneo and Java Sea region. All fleet units committed there - cannot cover evacuation in face of superior enemy air power and strong naval presence.’ Slim therefore agreed with Georges that he should abandon Saigon and concentrate his forces in Cambodia. Saigon accordingly fell on March 3rd…
Slim and Georges still had some 80,000 British, Indian and French troops under command, though the Indochinese element among the French forces was dissolving. After heavy air raids against Phnom Penh on 4th and 5th they ordered these forces to retreat into Thailand and accept internment. They considered whether to share their fate, but the Council ordered them to fly out, which they did on March 6th in a hair-raising flight across the Gulf of Thailand. ‘Lots of Jap planes about, but luckily none of them caught us,’ Slim noted. Not all Allied aircraft were so lucky: one squadron of Blenheims, reduced to five machines by constant action, was caught by fighters just as it left Saigon and all the remaining planes shot down. On 10th March all organised resistance came to an end, and some 50,000 Allied troops went into internment in Thailand. ‘A bitter pill,’ said M. Mandel, ‘after so many other losses.’ Mr. Churchill replied, ‘this too shall be redeemed.’
