Chapter 39
South-East Asian Campaign
December 7th - December 20th, 1941
In the early hours of December 7th, 1941, tragedy struck Hawaii as the conflict finally caught up with the United States of America. Suddenly, thousands of Americans were dead, and the conflict truly went global. The United States was now at war, and with it came Panama, Haiti, Honduras, Guatemala, Costa Rica, El Salvador, the Dominican Republic, Nicaragua, Cuba and the Philippines [1]. As president Franklin Roosevelt gave his “day that will live on in infamy” speech, it was said that many people cheered, watching from Algiers, London or Athens. However, half a world away, some were not cheering, far from it.
On December 8th, 1941, the Empire of Japan led a coordinated strike on Indochina, the Philippines, Malaya and Thailand.
In Indochina however, the Japanese encountered a first major setback. After the Franco-Japanese incident, Catroux knew that the Japanese could try something like that again. He thus ordered that the airfields be protected at all times, and had received the reinforcement of 3rd Squadron, Hell’s Angels, of the American Volunteer Group, operating from “Base 308” [2]. A large network of spotters also helped warn the airfields of the impending assault. As such, when the Japanese thought they would strike the airfields of northern Indochina with impunity, they would be faced with almost thirty fighters, French or American, modern or old! It was a carnage, as the IJA’s planes were caught completely unaware and ripped to shreds before they could reach their targets. Only the carrier strikes around Tourane had some effect [3], since the French did not think that a strike could come from there, and as such their CAPs were weak compared to the larger ones in north Indochina, not to mention the absence of a network of spotters. However, warned, the airfield at Hue had time to react and inflicted heavy losses on the Japanese before being annihilated.
The sheer devastation of the attack at Tourane left the French no doubt: carriers were involved, and likely many! This led the French to believe that the next likely attack would come to Cam Ranh’s naval base, which was deserted of heavy units. These ones had been ordered to sortie a few hours earlier, to avoid being caught like the ones in Pearl Harbor. With this in mind, the French decided to ambush the force coming to bomb Cam Ranh, which was met with partial success. Although the Japanese were shocked by the volume of the reaction, the French aircraft paid a heavy toll for their attack, as the escort provided to the naval bombers was still strong. Their sacrifice did ensure minimal damage to the French naval installations and fuel reserves in port.
In the early afternoon, Japanese forces started to land south of Tourane. The choice made by the Japanese command was simple: the French were simply not expected to have stationed units there, the area had several airfields, and it would cut the Hanoi-Saigon Road, therefore severing Indochina in two.
Here too, they were duly disappointed. The Tunisians of the 12th RTA, stationed at Hue and Da Nang, fought back with ferocity. Well-trained and experienced after fighting the Italians in the desert, the 12th RTA held firm despite heavy aerial bombardment, alienating the Japanese, though the main objective had been reached: the airfields at Tourane had been knocked out, and fighters could now operate from these bases. Kondo's squadron thus turned south...
In the meantime, the Japanese also assaulted the fortifications on the border. Lang Son and Cao Bang were thus relentlessly struck, but did not break. The reinforcement of these fortifications, which had taken the whole year, had paid off. General Kita’s divisions found themselves breaking their teeth on these jagged rocks, with the air force incapable of harming the monsters of concrete.
The Japanese command was getting worried by this point. They thought that the French had only very small units in the area, and that Indochina would fall within a week. As it did not happen, more pressure was put on the naval and air forces to get things done. The transfer of a considerable number of Ki-43 and A6M1 "Zero" from Hainan and the Paracels to Tourane helped the Japanese stabilize their position. During the night of December 8th, a large raid struck the French at Saigon, critically taking out most of their Hudson naval reconnaissance aircraft.
For the French, the first few days had been encouraging, but they still had massive problems. The beachhead at Tourane was expanding, and imminent fall of the airfields would mean that the French air assets would get overwhelmed sooner or later, especially after the Tan-Son-Nhut raid. And there could be no question of receiving the reinforcement of the other AVG squadrons, since they had been routed to Moulmein to cover the Thais, which were in much more dire straits. In Saigon, local battalions had started to be formed from the local population and the Chinese, with the rice reserves being evacuated while the sea lanes were not completely under Japanese control.
Catroux thus had no choice. He needed to dig in and hope for air reinforcements from France, and quickly! In fact, his pleas had been heard, and French and British alike had planned a massive convoy for the Far East…but it would take time to reach there. At Lang Son and Cao Bang, pressure continued to mount on the French (mostly Foreign Legion units reinforced by local battalions). In both these cities, the French experienced the first banzai charges of the war, to their shock and horror.
The fights were grueling, but on December 13th, Cao Bang broke, the same day as the fall of the French concession of Kwang-Tcheou-Wan. Catroux ordered the remaining units to withdraw to Bac Can, the last real obstacle in the area before Hanoi. If this one fell, Lang Son would need to be evacuated as well. Luckily, there was more than a hundred kilometers of mountain roads between Cao Bang and Bac Can, and the Japanese were human. Hanoi was safe for the moment.
At sea, things were developing. French submarines had reported the presence of a large task force in the South China Sea, and there was mounting pressure on the navy to do something about it. Admiral Bérenger knew that he had no chance against three carriers, but these seemed to have been sent southwards after the fall of the Tourane airfields. In fact, the carriers had been sent southwards to support the Thailand landings and possibly save the Kota Bharu beachhead [4]. On December 12th, the French fleet sallied towards a convoy bringing in reinforcements to the beachhead, but it had sailed right to its doom.
In the night, Admiral Bérenger’s squadron had encountered Admiral Tanaka’s light attack force, led by the cruiser
Jintsu. Like their comrades on land, the seamen were about to come face to face with a deadly asset: the Long Lance torpedo. In night combat, the Japanese seemed to be everywhere, and even Bérenger’s experience couldn’t help. The torpedoes executed almost every vessel of the Far East Fleet, including the American cruiser
Boise. Out of the massacre, there were only two survivors: Bérenger’s flagship, the cruiser
Lamotte-Picquet, and the destroyer
Milan, which both dashed southwards to Singapore. However, it had all not been for naught. In the fighting, the destroyer
Kuroshio was sunk, and the cruiser
Jintsu was damaged. While limping back to Hainan, this one was intercepted and sunk by the submarine
La Favorite, taking admiral Tanaka with it…
In Tourane, while the situation had turned to the advantage of the Japanese, progress had been slow. The 12th RTA had hunkered down in Hue, so the logical axis of attack for the IJA was now southwards towards Cam Ranh and Saigon. Something that the Imperial Army was fine with, until they realized that it would not be a triumphal march southward. At Quang Ngai, barely one hundred kilometres south, the Japanese trucks were ambushed by French armoured vehicles, who sent them running.
Thinking they were just facing a couple trucks with a mounted gun, the IJA sent their Ha-Go light tank, feeling that they would just brush aside any resistance. Unfortunately for them, the first tank to roll towards the town blew up…and the one in the back of the column too! Trapped, the rest of the light tanks of the column were completely annihilated one by one.
In the bushes, captain Pierre Billotte grinned. The veteran of Sedan and Stonne had managed to rally Algiers and had just done to the Japanese what he had done to the Germans back in May 1940. Except then he was in a clunky and heavy B1bis, and now he was in a much more manoeuvrable but no less deadly S-50 “Arcole”. The Japanese column was completely awestruck. Never in their wildest dreams had they thought that the French could bring armour to this fight.
With the Tourane airfields having fallen however, Cam Ranh was now too exposed. The French submarines were thus ordered to withdraw to Singapore once their patrol was over. Their submarine supply ship had in fact already left the place following the Japanese raid.
On December 18th, the Japanese launched a dual assault. One on Bac Can, which they had finally been able to reach, and one on Quang Ngai. In fact, while Bac Can held on, the Japanese managed to punch through Quang Ngai without any issues. General Touzet du Vigier had refused to risk his precious tanks under the threat of aircraft from Tourane, and had angled his resistance southwards, towards An Khe and Quy Nhon. Worse for him, he could not expect any support from the 3rd Indochinese Division, which was initially promised to him, but which now had to run towards the Cambodian border, as the situation in Thailand continued to degenerate. In fact, with the fighting at Bac Can, general Catroux also had no choice but to redeploy the 12th RTA from Hue northwards, leaving the Imperial City toothless against the Japanese, who seized it on December 20th, committing their usual exactions in the process.
However, everywhere else, the situation seemed to stabilize despite increasing air pressure. The Japanese effort in the north had been blunted and Lang Son continued to hold out. While the situation in the center of the country was poor, the Japanese still had yet to reach Cam Ranh, and Saigon was not yet threatened. Only the situation in Thailand gave cause to worry, with the imminent fall of the airfield at Don Mueang and the progression of Japanese soldiers towards Battambang and Siem Reap.
And on the Japanese side, things were infuriating. The Navy had been unrelenting in its shaming of the Army, which had failed to achieve even the most basic objectives against the colonialists, while they had annihilated three enemy fleets since then! The Army had collapsed, and even been defeated in Malaya! Only the Navy's valiant efforts, with carriers dashing in and out of the South China Sea, had managed to keep the Japanese offensive afloat. In fact, Admiral Kondo wished to prove that the Navy was superior to all by annihilating the threat of the pesky French armour stuck at An Khe and Quy Nhon, just like it had broken the Thais a few days earlier. He sallied his fleet towards Indochina with his carriers, reinforced by the seaplane task force which usually covered the Philippines, and struck French positions with his “Val” and “Kate”, claiming “twelve tanks destroyed and many more damaged”. In fact, the French reported two M3s destroyed and two M3s and one S-50 damaged but repairable. The effect of the bombardment was more crushing to morale than anything else, as it was done with barely any opposition from an air force too preoccupied to defend Saigon’s airfields and the Hanoi area.
However, such a move was still risky for Kondo. His ships had strayed southwards, right into the Allied submarine line. And in the evening hours of December 20th, as his fleet steamed off the Paracels, the inevitable happened.
An explosion shook the night sky, and as sailors looked on to see where it came from, they were struck with a horrid sight: the carrier
Shoho, in flames, sinking to the bottom of the ocean along with 700 crew and 35 aircraft. The submarine
Casabianca had claimed its first victim. And the Japanese were now left with one less carrier.
