January 2nd, 1943
Burma (Allied front) - In the early days of 1943, General Wavell, Allied Commander-in-Chief for Southeast Asia, has under his command Lieutenant-General Alan F. Hartley, GOC India - whose role is mainly to recruit and train fresh troops - and Arthur Percival, ex-GOC Burma. The latter commands the British 9th Army. His troops were able to be reinforced and re-equipped during the monsoon period, which is coming to an end. In fact, there is no shortage of potential reinforcements - the hard part is getting them supplied. This is why Percival's forces are smaller than they could be.
Because of these logistical difficulties, the active phase of Operation Roundshot, which is to see the recapture of Singapore, is postponed until the 1944 dry season. At that time, the Royal Navy should be strong enough to land people in the isthmus of Kra, while supplying abundantly the forces engaged in Burma. Meanwhile, the 9th Army must, for 1943, be satisfied with limited offensive actions, holding firm, in any case, on the line of the Salween - this is Operation Anakim. However, at 10 Downing Street, it is hoped that these actions will be able to bring about the changeover of Thailand, "in the Italian style", as Winston said...
It is the XV Indian Corps, commanded by Lt. General William "Bill" Slim (recently promoted), that holds the Salween front. From south to north, this corps includes the 14th Indian Division under Major General W.L. Lloyd (47th, 48th and 49th Indian Brigades), Harvey's 8th Indian Division (17th, 18th and 19th Indian Brigades) and Major General Bruce-Scott's 1st Burmese Division This one is actually not very Burmese, since it is composedthe 1st Burmese Brigade (reconstituted with the debris of the 1st and 2nd Brigades, which had disintegrated under the first shock of the Japanese attack), the 55th Indian Brigade and...the Expeditionary Force of the Belgian Congo.
....
This Corps is a very reinforced brigade of about 8,000 men, commanded by General Major Auguste Gilliaert. English, Indians and even Burmese look with suspicion on this unit (this is how the Indians and Burmese speak of the Congolese, even if their own skin is not much darker) and their white officers, who speak French but are not French, or who speak Dutch (it seems) but are not Dutch...
However, their equipment is of good quality and they have a field hospital, commanded by Captain Thomas.
Even better, the Public Force arrives in Burma with its own air support, which the British have labeled 1st (Belgian) Composite Group. This group has about 120 aircraft. It is accompanied by a strong support battalion: mechanics, transmission, administration, engineering (runway repair, mine clearance), protection (a platoon of motorized infantry) and flak (four quadruple .50 mm guns, four double 20 mm Œrlikon guns and a battery of four 40 mm Bofors).
...
In addition, Slim could rely, if necessary, on the reserves of the 9th Army: east of Sittang, the 5th British Infantry Division (Major-General H.P.M. Berney-Ficklin - 13th, 15th and 17th Brigades) and, west of the Sittang, two armored brigades.
The 9th Armoured Brigade (Brigadier John Currie - 3rd Hussars, Warwickshire Yeomanry) aligns about one hundred and ten tanks, Crusader, Valentine and Stuart. Its crews are relatively experienced, but the rate of unavailability of its tanks is quite high due to the climate and the chronic lack of spare parts.
The 50th Indian Tank Brigade (Brigadier G.H.N. Todd) has a small number of tanks, Valentine, Crusader and Tetrarch (these very light and manageable tanks were designed to be airborne, but it appeared that the smallest Panzer III would be a formidable enemy for them and that their life expectancy would be longer in the Asian jungle, where their small size would be an asset). Most of its crews are novices, but they were trained under the guidance of tankers evacuated from Malaysia and Singapore, who are eager to return to combat and some of whom have been incorporated into the new brigade. In addition, we must add to them the thirty armoured vehicles of the already famous Calcutta Light Horse, which had worked wonders during the first Burma campaign and which was completely re-equipped with Stuart's equipment. Its men (most of them British living in India for many years) asked and obtained to be attached to the Indian brigade rather than to the 9th Armoured.
Finally, two independent brigades with a particular role are added to these forces. The 13th Indian Brigade, very experienced and whose staff decided to make a "jungle school" for new recruits, is stationed not far from Rangoon. And the 77th Indian Brigade under the command of Brigadier Orde Wingate, made up of British reservists, Burmese and Gurkhas, is training in the jungles of northern Burma.
.........
All these people are supplied by two ways: naval, by Rangoon, thanks to convoys coming from India, and by land, from the north, thanks to the road and railroad from Imphal.
The naval route benefits from the allied presence in the Andaman Islands, whose air bases allow the coverage of a good part of the east of the Indian Ocean. If the Royal Navy is not yet ready for offensive operations in this sector, Their Lordships assure Wavell and Percival that they need not fear a Japanese landing in Arakan as long as the Combined Fleet is occupied in the Pacific.
As for the land route, this dual artery is so fragile and valuable that two divisions directly attached to the 9th Army HQ are deployed to protect it from enemy raids, but also and perhaps above all to maintain it. Indeed, the climate (monsoon and altitude depending on the place and the season) inflicts serious damages on it daily and it must be cleared to allow the passage of trains and trucks. The 19th Indian Division (Major-General T. Wynford-Rees) is deployed between Rangoon and Mandalay. Further north, between Mandalay and Imphal, there is the 11th East African Division (Major-General Charles C. Fowkes).
In addition, west of Sittang, on the "Burma Road", the land route benefits from the presence of the Chinese Fifth Army (General Du Yuming), whose strength is roughly equivalent to that of a British division. It has its own air cover and has shown during the March fighting that it could be counted on.

Finally, as for the RAF and the allied air forces in the region, their numbers are still relatively limited and the models that equip them are far from being all the most recent of the British and American industries!

Sqn 344 (B): 14 Savoia-Marchetti 79 and 81** and various light aircraft (these aircraft were gradually replaced in 1943 by Lockheed Lodestar and Piper Cub and some UC 64 Norseman***).
Sqn 345 (B) [Major Gérard Greindl] : 15 Fairey Battles (+ 3 reserves), progressively re-engined as Night Battles (the latter will be replaced at the end of 1943 by Bell P-39 Airacobra).
To the list of Belgian aircraft we must add a single DC-3, carefully maintained, which is charged with transporting (among others) the personalities. Two Belgian ministers (the one of the Colonies, Albert De Vleeschauwer, and the one of Defense, Antoine Delfosse) did they not make the trip to Burma?
Burma (Japanese front) - On the Japanese side, the 7th Army is still commanded by Lt. General Jûichi, but it has been considerably reinforced compared to the end of the campaign of early 1942. The 55th Division, which had played the leading role in 1942 but had suffered a great deal, has somewhat replenished the ranks of its 112th and 143rd Regiments. Much better, its 144th Regiment has been recalled from Guam - the end of supply operations on Guadalcanal has just freed up enough transports to allow this redeployment.
Since the capture of Singapore, the 55th has received reinforcements: the 12th Division (24th, 46th, and 48th Regiments) and the 71st Division. The 5th Heavy Field Artillery Brigade and the 9th Armored Brigade, present in 1942, are still there, but the losses suffered by the 9th Armored Brigade could only be compensated by the contribution of the surviving elements of the 7th Armored Brigade, which had participated in the fighting in Singapore. Finally, the 2nd Thai Division continues to assist the Japanese, but its main role is to cover the lines of communication.
The reinforcements seem important on paper, but the 12th and 71st Divisions had lost much to the Singapore defenders and are far from their best form, both in terms of manpower and heavy equipment, especially artillery.
The Army's air force is there, of course, and had been modernized; but the 1942 campaign had showed that it could not be enough to ensure victory.

Nevertheless, the orders from Tokyo are clear: resume the offensive and take Rangoon.
The objective is to complete the isolation of China by closing the Burma road, depriving the Chinese of the Western equipment to which the general staff attributes all the Japanese setbacks in China. But it is also a question of controlling Burma's natural resources (oil, rice and tungsten for anti-tank shells).
To achieve this, the Japanese general staff devised a bold plan, Operation U-Go. This plan requires the cooperation of the Imperial Navy and the Thai Navy. This part of the of the operation is a major factor in the fact that U-Go will not begin until mid-January, a few weeks after the end of the monsoon season. The decrease in naval requirements due to the end of the fighting in Guadalcanal makes it easier to concentrate the necessary resources.
However, the Imperial Navy also suffered heavy losses. It could only delegate the light cruiser Katori, normally dedicated to training, the destroyers Arashio, Hagikaze, Hibiki and Oshio and the 1st Torpedo Boat Division reconstituted with the surviving ships of the Pedestal convoy battle: the Hatsukari, Kasasagi, Otori and Tomozuru.
However, the Thais will have the privilege to use their fleet in other ways than as a target! The battleship Sri Ayudhya (2,265 t, 4 x 203 mm), laboriously refloated after the serious damage suffered against the French in March 1941, found herself the flagship of the bombardment squadron, which includes only her and the coast guards Ratanakosindra and Sukhotai (4 x 152 mm each). The torpedo boats Patani, Phuket, Rayong and Surasdra will assist their Japanese colleagues. These ships, under the command of Admiral Omori Sentaro (who put his flag on the Katori), will escort a convoy including transports that participated in the landings of the beginning of the year on the east coast of Malaya and will embark the 27th Infantry Division - or more exactly what remains of this division after the hard fighting of the two sieges of Singapore. The 27th Division is to be landed on the coast of Burma, behind the back of the Allied defenses.
Obviously, the chosen region is the Irrawaddy delta, which means that the enemy will be able to hold on to many "wet cuts". But the Imperial Army has confidence in the abilities of its men and did not intend, in any case, to provide them with trucks and other vehicles. Tanks are certainly provided, but most of them are light amphibious vehicles Type 2 Ka-Mi, very convenient on this terrain, but as poorly armed (one 37 mm gun) and as poorly armoured (6 to 13 mm) as most of the Japanese armoured vehicles.
The escort is not very imposing, but it is a calculated risk. Certainly, the Imperial Navy, busy containing the Americans in the Pacific, did not have the means to face the bulk of the Eastern Fleet in the Indian Ocean in a pitched battle, but only the Allied ships based in Rangoon would be in immediate range of intervention, since the large British ships had long since retreated to Ceylon. Before they could intervene, the troops put ashore by surprise will have achieved victory in Burma. The Japanese general staff fears submarines, so the escort will be completed by some Japanese and Thai submarine hunters.
* The Fury, if they are officially in the inventory, have not been operational for several months! Four of these aircraft are now carefully preserved in Indian air bases or museums.
** The two SM 73s and the two SM 83s were returned to Sabena, in a mediocre condition it must be said...
*** And even, in 1944, by some Sikorsky R4b helicopters.
