SITREP FOLLOWS
CURRENT DATE: 1-APRIL-1942
INDIA/BURMA COMMAND
Initial operations in this area by the IJA and IJN forces did not begin until early March 1942. Before that time period only random air attacks against the air groups of 221 Group, and the AVG. 224 Group RAAF bombers escaping from north Malaysia were involved in night raids on Bangkok. The RAF Buffalo fighters based in Rangoon were depleted over the course of the campaign.
The AVG groups were hard hit but a surprise Japanese air raid that damaged or destroyed a large number of fighters at Toungoo early in the campaign. 2nd and 3rd AVG provided additional combat air patrols over Rangoon from their base in Toungoo. Air-to-air combat over Rangoon was particularly fierce with the 1st AVG being reduced to a single operational H8-A3 aircraft by mid-march 1942.
Port Blair reinforced by naval transport of RAF personnel, 2 Buffalo Fighters and a lone Swordfish Torpedo bomber. The ships bring over the RAF base force were sunk by Betties while unloading. Subsequent supply delivery missions have cost 3 small coastal cargo ships. The base is currently being bombed by substantial Japanese air assets. The fighter flight at Port Blair now has lost both its planes while the Swordfish flight is up to 3.
British 18th Division intended for Singapore was diverted to Colombo and is currently undergoing tropical training there. AA and AT assets were also diverted from Singapore and are present in Colombo (AA), Imphal (AA) and Cox Bazaar (AT). HQ III Corps is loading in Cochin for transport to Colombo. 2 Indian Divisions are forming currently to reinforce Eastern Command and the 70th Division brigades are currently either at Aden or in transit to Karachi. The command group for the 70th Division is enroute for Calcutta.
Australian I Corps troops are now all in theatre. The 16th, 17th, and 18th brigades have been temporarily assigned to missions. The 16th is garrisoning Diego Garcia, the 17th is in Cox Bazaar, and the 18th is in Chittagong. All other Australian forces are scheduled to return to Australia from Cochin as shipping is available. All I Australian Corps assets are in India and most are now in rail transit to Cochin.
The 2 Indian brigades sent in to reinforce Rangoon were caught by torpedo bombers though the RAF and AVG tried to give air cover. The actual troop losses were not bad as the ships were caught in the river delta and most troops were rescued by the motor launches sent to help. Salvage operations recovered most of the two brigade’s heavy equipment.
Burma Corps resisted the Japanese invasion that began in early March 1942 but were initially caught by surprise with a naval landing at Moulmien. This resulted in a brigade and a regiment of mountain guns caught behind the lines. The attempt to stop the Japanese advance at Pegu was decimated by a tank onslaught and the forces fell back to Rangoon. The battle for Rangoon itself was fierce with the British and Burmese troops resisting for 4 days until overwhelming numbers (4 IJA Divisions, 4 Tank Regiments and support troops) forced them out of the city. Viper Force and the Burmese Railway Bn that was attempting to entrain to Mandalay were destroyed in the combat.
The loss of both Rangoon and Pegu forced the AVG to relocate. The ground elements and the 1st AVG went to Lashiro. The 2nd AVG went to Kumming and the 3rd AVG when to Chungking. The Chinese were convinced to release 2 divisions from the 11th Army to reinforce Lashiro. Burmese battalions and brigades have contested the Japanese advance and in all cases managed to execute an effective retrograde movement to Myitkyi. This base is now held by a Burmese Bde and 4 Burmese Bn supporting the Base force and Auxiliary AA regiment. 221 Group command staff and Burma Corps command staff were airlifted out of Myitkyi to Ledo and are currently based in Sichar. Kalemyo is held by a Burmese Bde and Bn with a Base Force marching to it through the jungle. Unfortunately both of the Burmese Bde suffered serious casualties to Japanese armoured forces in their battles over Mandalay and Schwebo. Neither is currently fit for combat. The 3rd Burmese Bde along with a regiment of mountain guns has abandoned the plan to move to Lashiro and is marching through the jungle to reach the main road from Prome to Mandalay they will then proceed north crossing the river south of Magwe and then on to Kalemyo. The survivors from Rangoon marched up the coast road towards Akyaba. Unfortunately the Japanese landed a strong force in Akyaba forcing out the Burmese battalion garrison. The forces will now assemble in the jungle and cross the river just north of Akyaba and then march to Cox Bazaar. Tuning Gyr was assaulted by Thai troops that drove out its garrison battalion. The battalion is screening the approach to Lashiro.
Imphal is held by the Royal Tank Bde, an Indian Infantry Bde, heavy and light AA regiments, a mountain gun regiment and a base force, with a field gun regiment marching from Sichar. Chittagong is garrisoned by an Australian Bde, the fortress troops, heavy and light AA regiments and a battalion from the Assam rifles. Cox Bazaar has an Australian Bde, the Hussar tank Bde, a regiment of 2 lbers, a mountain gun regiment and a battalion of Burmese light infantry.
RAF Operations (221, 222, 223(-), 224, 225 Groups)
221 Group will be based out of Sichar once its airfield is developed. Along with a squadron from 224 group and 225 group it is undertaking harassment bombing of the main body of IJA troops currently located near Katha.
222 Group is based in Colombo and is undertaking training and search operations from there. It has primary responsibility for defence of the RN base.
223(-) Group is based in Madras and is undertaking training and acclimatization while waiting for transhipment to Australia.
224 Group is based in Madras and will be responsible for air defence of Southern Command.
225 Group is based at Dacca and is contributing to the harassment of the IJA units in central Burma.
All transport aircraft are currently in Ledo and are involved in transport of supplies to either China or Myitkyi. More transport squadrons are in Aden currently waiting for ships.
The Mohawk squadron based in Calcutta has been involved in several engagements with unescorted IJA bombers. The five pilots are gaining valuable experience and will likely soon be aces. Other groups are patrolling the coasts of India. On board cargo ships heading for Cochin from Cape Town are a headquarters squadron and the 16th pursuit squadron of the 51st PG from the Tenth Air Force flying P40Es. These planes will be based in Dacca. The most obvious lack is in patrol air craft to cover the Bay of Bengal.
The current plan is to reorganize the forces assigned to 223 and 224 groups and return the Australian bomber group to Australia plus other squadrons, and to return to India various RAF squadrons currently deployed near Darwin. This will make 223 Group a combined RAF/RAAF/RNZAF force and it will be responsible for assisting in the defence of NW Australia. The question still on the table at AIRHQ India is which squadrons will be shuffled where.
RN Operations Bay of Bengal
Current forces:
Force R: HMS Indomitable, CAx2, CLx2, CLAA, DDx4. Sortied from Colombo against the landing at Moulmein. Took up station 120 nm SW of Ramree. Albacore I torpedo bombers made repeated attacks against unloading transport ships. Fulmar II fighter bombers caught by Oscar’s and handled roughly. Retired to Colombo when torpedo magazine empty. On station at Colombo.
Eastern Fleet: HMS Warspite, 4 R-Class BBs, CLx3, DDx4 Sortied, pre-reinforcement (only the Royal Sovereign present), against the shipping at Akyab with Force R providing air cover. No ships present. On station at Colombo.
Hermes Task Group: HMS Hermes, CA, CL, DD. Conducting ASW operations near Karachi.
Reinforcement Group: HMS Formidable, CA, 2 CL, and 3 DDs in transit from Cape Town. Two of these ships were part of the screening force sent with the Prince of Wales (CL Dragon and DD Iris). The Dragon's damage was repaired in time to join the Indomitable.
3 CLs, 6 DDs, 1 DE and several small escorts are employed guarding transport groups. Several KVs and other small escorts engaged in ASW operations near Colombo, Bombay and Karachi. 3 Patrol Craft used as a rapid reaction force based in Calcutta to engage attempts to reinforce Akayba. The rapid reaction force ships have sunk one cargo vessel in a night engagement so far. HMS Prince of Wales currently in Cape Town shipyards with a repair estimate of approximately 1 year (System: 45; Float: 54 (major), Engine 34(24 major)).
Submarines from the Dutch, British and American navies are currently based out of Colombo and are transiting to patrol areas in the Bay of Bengal and near Sumatra and Java.
((Some of the above numbers are approximate as I can’t recall them exactly.))
The failure to deploy a major force against the landing at Moulmein is considered a lost opportunity by Eastern Fleet HQ. It was not originally though to be so major a landing as it was expected the main attack would come over land. Had the Eastern Fleet surface elements with its battleship sortied against the landing and had the Hermes Task Group accompanied Force R there would have been significantly higher losses of Japanese assets. The Eastern Fleet was not deployed mainly due to concern over land based air strikes such as those that caused the loss of the HMS Repulse and damaged the HMS Prince of Wales.
Imperial Japanese Army Dispositions
Akyaba is garrisoned by 2 units with at total troop strenght around 9000 men. Photo recon is ongoing. There are likely base forces and other land forces in Rangoon and Prome. Air assets were briefly based in Mandalay but night bombing raids from Dacca based bombers drove them out. Most of the Japanese air assets seem to be in Rangoon and Prome. Oscars, Betties, and Sallies have been observed in attacks on Port Blair, Lashiro and Calcutta.
A Thai division is located at the trail crossing east of Taung Gyi.
A large Japanese force…reported at nearly 60,000, 600+ guns and 300 AFVs…is located near Katha. At least 4 IJA divisions, 3 Tank Regiments and a Recon Regiment were present at Rangoon along with support troops. At the moment where the Imperial high command may be planning on going is unclear.
((Other commands to follow. I truly kick myself for not hitting that landing harder and for it sneaking in, but I had only limited patrol air assets there. Basically the planes from Hong Kong and I was expecting him to come over land as I had a japanese land force visible so the combined land-sea assault caught me off guard. The picture below is the state of things approximately mid-march, as you can see some plans have changed.))
