15th August – 29th September 1944 - The Liberation of Hong Kong – Part III – The Walled City, Operation Candid and the Final Liberation
As the Japanese forces were pushed back towards Kowloon City the British slowed their advance, not wanting to rush into what they expected to be a potentially bloody house to house battle for control. Their advance came to a complete halt on the 2nd of September, less than four kilometres from the outskirts of Kowloon. Sakai’s demands for constant counterattacks and the actions of Unit 731 had promoted a degree of caution on the part of the British and while they had no intention of allowing the fighting to drag on, they were willing to engage in a period of siege warfare to wear down the defenders, already short on food and ammunition and becoming more so every day as the Japanese persisted in skirmishing with the British forces even as they were trying create some sort of viable defensive position in the city. This made life even more miserable for the unfortunate civilians trapped in Kowloon with the Japanese as what food they had left was requisitioned by the Japanese, meaning that they ripped through every house and building searching for any scraps the residents might have saved to fend off starvation, it was a given that anyone who had succeeded in doing so faced the full wrath of the desperate Japanese soldiers [1].
The British began an artillery bombardment of Japanese defensive positions in and around Kowloon. It was impossible to hit these positions without inflicting significant civilian casualties, in no small part because Sakai was still pursuing the use of human shields, preventing the population of Kowloon from fleeing despite the extra strain this placed on the meagre resources in the city. Some on the British side were hoping that there might be an uprising in the city of the sort that had greatly helped their operations in Thailand in Indochina, however the population had been thoroughly ground down by the Japanese during the occupation and those inclined to resist the Japanese had long since fled into the countryside. By and large the people trapped in Kowloon simply sought to keep their heads down and hope to survive the inevitable British onslaught. The British were not entirely insensitive to the plight of the civilian population and on the 10th of September they called a halt to the artillery attacks and sent out a delegation to try and negotiate a surrender with the Japanese. This can be seen as a cynical gesture on the part of the British, going through the motions so they could claim they had tried to spare the civilians even though they knew there was little to no chance of the Japanese accepting any terms the British might offer. If this was the view of the British commanders then it was borne out when the Japanese refused to even meet with the delegation, even going to so far as to threaten to open fire if it did not promptly withdraw [2].
With this formality completed the British opened up with their artillery once more, significantly increasing the volume of fire on the morning of the 11th as they launched an assault on the west of Kowloon, led by several companies of A22 Infantry Tanks, though by this point the British had begun to adopt the Heavy and Medium nomenclature instead of the Infantry and Cruiser designations. The A22 was well suited to leading an assault where speed and the ability to engage enemy armour were not critical factors and instead their thick armour and ability to simply plough through obstacles was paramount. Many of these tanks had also undergone field modification with addition of cages around the turret to prevent troops climbing onto the top and grilles designed to deflect grenades and Molotov cocktails. Some also had the so-called Rhino blades, bulldozer type attachments that further enhanced the Black Prince’s ability to push through obstacles, as well as making it harder to throw satchel charges under the tank [3].
With nothing more than a few light artillery pieces available to them the Japanese defenders could do little to stop the tanks, especially as they were closely supported by infantry. This co-ordinated action allowed the assault to make rapid inroads into the city and the Japanese determination to fight house to house and floor to floor in every street counted for little when the British had the firepower to clear out every strongpoint and blast apart any defence however determined and by the 15th the Japanese forces had been surrounded and forced back into the Walled City, which was something of a misnomer in 1944 as the old wall had pulled down soon after the invasion in 1941, with the material earmarked for use in expanding Kai Tak airport. It was hardly an impenetrable fortress and even as the British prepared to mount their final assault in Kowloon they were launching Operation Candid [4].
Operation Candid had originated during the overall planning of the battle and the idea was for a direct assault into Aberdeen Harbour on the Southwestern corner of Hong Kong Island, using destroyers and fast boats to swiftly land a substantial body of troops and seize the port facilities so that further troops and equipment could be landed, driving a deep wedge into the Japanese positions while they were focused on the landings in Kowloon. Such a plan did not seem like a natural fit for Montgomery, whose signature was meticulous preparation and a relatively cautious approach. It was thus a surprise to some that Montgomery endorsed Candid, though not without it undergoing some revisions and improvements before it was put in motion. The force that set out on the night of 15th – 16th September consisted of a naval force led by the Cruiser
HMS Belfast, supported by seven destroyers and nine Motor Torpedo Boats, eleven had originally been intended to take part but two had suffered mechanical issues in the days leading up to the beginning of Operation Candid [5].
The Japanese had done nothing to improve the defences around harbours of Hong Kong since 1941 and indeed outside of Victoria Harbour on the northern side of the island they had not even bothered to maintain what they had inherited from the British. The expectation of swift victory followed by the needs of other places on what had been the frontlines of the war had left nothing to spare with which to protect Aberdeen harbour. There were no search lights, no mines, and no artillery pieces covering the harbour and what troops were assigned to the area were there to prevent acts of sabotage and theft. These patrols had been expanded as the threat of a landing drew closer and a few machine gun nests had been set up in a rather perfunctory manner. This was all done with a view to defending against a small-scale raid, not the nearly 1200 troops approaching aboard the MTBs and destroyers, mostly made up of No.7 and No.9 Commando, supported by a contingent from the Pioneer Corps [6].
With their lights extinguished and dark grey paint applied over the superstructures the ships were able to approach almost completely unnoticed until the MTBs went to full speed and raced towards the docks to put the first wave of commandos ashore. This provoked more confusion than alarm among the Japanese troops patrolling the harbour and it was only when soldiers who went to investigate the sudden flurry of activity came under fire that they realized that this was an attack, though they had little opportunity to report this fact as more British troops came ashore and rapidly moved out and took control of the quayside, with the destroyer
HMS Havelock being the first to tie up alongside and offload the 143 men crowding it deck. She was soon followed by
HMS Garland,
HMS Highlander, and
HMS Imogen. By dawn the British had taken control of the docks and this paved the way for two liberty ships converted to serve as troop ships to land another 786 officers and men as well as artillery pieces, armoured cars and a small number of light tanks, allowing the attacking forces far greater mobility than the defenders [7].
The element of surprise in the attack had been total and as dawn broke the FAA made a significant contribution to keeping the defenders disorganized as strike aircraft from the carriers
HMS Illustrious and
HMS Ark Royal hit a number of key targets on the island with a mix of bombs and 4.5in rockets. Among the targets hit was the main Japanese command post for Hong Kong and when the aircraft attacked they caught the entire senior staff, including General Sakai, in the building. The aircraft inflicted devastating damage and Sakai’s remains were buried in the rubble along with his staff, or at least this must be assumed even though his body was never definitely identified in the aftermath. This amounted to a decapitation strike as Japanese command and control in Hong Kong collapsed in the aftermath. Counter attacks were sporadic and easily rebuffed by the British, who steadily pressed onwards and expanded their perimeter. The Japanese certainly did their best to resist, but they lacked the number and co-ordination to make the kind of bloody last stand the defenders of the Walled City did [8].
The British initially hoped they could reduce the Japanese defences in the Walled City in two days, in the end it took six as they were forced to inch their way forward. The confines of the Walled City limited the use of armour and the Japanese liberally spread booby traps throughout the area, including planting them among groups of civilians, forcing the advancing troops to treat the hapless Chinese residents with considerable circumspection. It did not help that there was an outbreak of Typhoid among the residents, which provoked considerable alarm among the British command after their previous encounter with Unit 731. In this case the outbreak seems to have been the result of bad food, bad water and inadequate sanitation, though even in the absence of any paper trail the possibility that it was deliberate has never been entirely ruled out. This outbreak accounts for the photographs of British soldiers fighting in the Walled City wearing gas masks, though the reality was that this was far rarer than many people assumed. The masks were in short supply, completely unsuitable for the combat conditions the British were operating in and the masks that were available had been held in storage for years and rubber parts had perished in many of them rendering them useless. This does not even address the fact that they would have little effect on exposure to diseases spread through contaminated water or insect bites [9].
Had the Japanese been able to make the entire battle for Kowloon as bloody and exhausting as the fight for the Walled City then perhaps Sakai might have been able to force the British to pause their operations and reconsider their future strategic plans, though it is doubtful the outcome of such considerations would have benefitted Japan. As it was as desperate as the battle became it was simply relegated to being one more hard fight among many others and by the 24th the British had complete control of the Walled City and the whole of Kowloon. The fighting on Hong Kong Island lasted until the 29th and if it lacked the intensity of the battle for the Walled City this was only because the British were able to break the Japanese forces down into a series of isolated pockets that were reduced one by one. Despite the speed of the British advance on Hong Kong Island the Japanese troops on the island could not be prevented from carrying out atrocities, including the murder of several dozen POWs, executed before the British could take the camp they had been moved to as part of Sakai’s human shield tactics [10].
The liberation of Hong Kong technically marked the end of the road the British had been pursuing in Asia since they had held the line in Malaya against the Japanese in December 1941. Every corner of the British Empire was once again in British hands, even if the relationships in some of those corners was subject to change. Some in London did feel that this should mark the end point for British offensive operations in the war, at least on the ground. The actions of the Japanese argued against such a stance, if they were allowed to turn the Home Islands into a redoubt, and continue to work on biological and chemical weapons while they did so, who knew what horrors they might unleash before they were defeated? There was also the consideration that if they attempted to stand aside and leave the remainder of the fighting to the Soviets and the Americans, they risked allowing those powers to dictate the terms of the peace, despite the massive contribution the British had made to the war in the Pacific. In the end the British would become involved in the planning for the invasion of Japan, and they would be drawn into one last amphibious operation, which has come to be seen by many military historians as Montgomery’s masterpiece [11].
[1] This is going beyond the usual brutality as their discipline is starting to crack.
[2] Cynical? Sincere? Probably a bit of both.
[3] These A22 crews have gone just a touch Mad Max.
[4] This is not going to be a slow grinding advance by the British.
[5] So Montgomery may just acquire a taste for flanking amphibious assaults.
[6] Closer to OTL St. Nazaire than Dieppe, but the British aren’t planning on pulling out.
[7] So ITTL there is a battle of Aberdeen…
[8] Sakai thus evades a war crimes trial.
[9] This is going to accelerate the deployment of Bomber Command to South East Asia among other things.
[10] And whatever political discussions may have been had in London the British are going to commit to the complete defeat of Japan.
[11] I will leave it to the reader to speculate where that might be.
