Major Grubert

Sorry I am confused. Do u mean the 1st division "was" or "was not" involved?

This is a post that u made a while ago in another thread:

"Lt. Col. Thwuan Wichaikhatkha's Cavalry Division served as the Phayap Army's left flank on the Salween.
It consisted of the 3rd, 4th, 5th, and 6th Cavalry Battalions, as well as two independent companies of motorised recon. troops."

May I ask about the about the designation of this cavalry division?

I shall reiterate the fact that no 1st Division was ever stationed on the Phayap front.

The cavalry division is simply the cavalry division.

A Forgotten Invasion: Thailand in Shan State, 1941-45

On December 8, 1941, Japanese troops invaded Thailand at nine separate points: by land, from Battambang in Cambodia, by air at Don Muang airfield, and by sea in seven amphibious landings between Hua Hin and Pattani on the gulf coast. Despite fierce fighting at points in the south, organised resistance lasted only a few hours. Field Marshal Phibun Songkhram, then Thai ruler, ordered a cease-fire, his government having agreed that to fight the Japanese would be suicidal. At this point Britain and the United States regarded Thailand as an enemy-occupied country and the innocent victim of Japanese aggression.

Unknown to the allies - and to most of his own cabinet - Phibun had other ideas. Influenced, perhaps, by the sinking of Britain's two capital ships, Repulse and Prince of Wales, within sixty hours of the outbreak of war in the Far East, he determined to seek an alliance with Japan. On December 14 he signed a secret agreement with the Japanese committing Thai troops to participate in the invasion of Burma, One week later, on December 21, 1941, Phibun signed a formal treaty of alliance with Japan in front of the Emerald Buddha at Wat Phra Kaeo, considered the most sacred object in all Thailand.

Phibun's reward for entering into this alliance was a secret Japanese guarantee to return to Thailand the Malayan provinces ceded to the British in 1909, as well as - with no comparable historical justification - the "lost territories" of Burma's Shan State. In pursuit of these aims, because he believed the Allies beaten, and because it was an auspicious day, on January 25, 1942, Phibun declared war on Britain and the United States.

As is well known, Phibun's action was opposed by most Thais as well as by Thailand's ambassador to Washington, Seni Pramoj, who simply refused to deliver the declaration of war to the US Secretary of State. Phibun, however, was determined that Thailand should both be on the winning side, and that it should benefit from the spoils of victory. Thailand, he announced, was a nation of great warriors who had to learn to adapt and make sacrifices. Part of this process was to recognise who the country's true friends were. Britain could no longer be counted as such a friend, as it had long deprived Thailand of some of its territory. And so... let loose the dogs of war!

In addition to his territorial aspirations, it is probable that Phibun was worried about the morale of the Thai regular forces, now that they had been faced down by the Japanese and had no obvious role in defending the country. As a result, he conceived the idea of creating a new "Northern Army" which would invade Burma and seize control of Burmese territory east of the Salween River - a territory then known as the Eastern Shan States. Since Thailand had already been promised parts of Burma which were regarded as "lost territory" in the secret protocol, the Japanese did not object in principle, though they were not prepared to allow Thai claims on Burma's Karen State, insisting that Phibun limit his territorial ambitions to Shan State. The Japanese also seem to have realised, as apparently the vainglorious Phibun did not, that a campaign of conquest in north-eastern Burma would be no walkover.

Japan also had to take into consideration the feelings of its Burmese puppet-allies. Under a hastily drawn up constitution which incorporated both democratic and totalitarian elements, Burma was to be "a fully independent and sovereign nation" ruled over by the Naingandaw Adipadi, or Head of State. The man chosen for this position was the Burmese nationalist Ba Maw. When informed of the impending transfer of eastern Shan State to Thailand, Ba Maw was naturally less than happy. At a meeting with Tojo, the Japanese strongman, in Singapore, Ba Maw commented that "Neither the Burmese nor the Shans will be completely happy about the dismemberment of the Shan territory and its people". Tojo was apologetic, but explained that Japan had promised eastern Shan State to Thailand as the price for becoming an ally. "But we have come in with you too", said Ba Maw, "and we also have our claims".

Command of Thailand's Northern Army was given to Luang Seri Roengrit, well-known in Bangkok for his patronage of the Royal Turf Club, but who had also successfully organised the transport of military equipment to the Cambodian border during the conflict with French forces in Indochina in 1940-41. The logistical problems Luang Seri faced in Shan State were quite different, however. The Thai railway system only reached as far north as Chiangmai (as, indeed, it still does today), and from there the troops of the Northern Army, carrying thei supplies, had to slog their way along rocky mountain tracks to the Burmese frontier. Many of the soldiers involved came from the north-east, and were not equipped to cope with the climate in the northern mountains. They were inadequately armed, poorly motivated - and they had no real idea who they were meant to be fighting.

Shortly after Japan's attack on Pearl Harbour on December 7, 1941, Chiang Kai-shek cabled Roosevelt and Churchill offering China's full cooperation in the Southeast Asian theatre. In particular, he suggested that Chinese Nationalist (KMT) troops should move into northern Burma to help protect the vital supply routes between Rangoon and Chungking. This offer was accepted, and units of the 93rd Division of the KMT army based in Yunnan moved south down the Salween Valley. Early in 1942 these KMT troops arrived in Shan State where, facing no immediate prospect of a Japanese attack, they settled down to live off the land. This peaceful existence was shattered on May 3, when planes of the Thai airforce bombed Kengtung as a prelude to the arrival of the Northern Army several weeks later.

Half a century later a senior Shan monk still living in Kengtung recalls the occasion: "The Thais sent 27 aeroplanes and most of the bombs were dropped at the market where the Chinese troops stayed". The bombing caused the KMT soldiers to retreat from the centre of Kengtung. A few weeks later Thai infantry led by Field Marshal Pin Choonhavan reached Kengtung and raised the Thai flag there. General Chatichai Choonhavan, the former Thai prime minister and current head of the Chart Pattana Party, then a young man with the rank of second lieutenant, was amongst the victorious Thai forces.

Phibun Songkhram was predictably delighted. He announced that the victory of the Northern Army had vindicated the reputation of the Thai armed forces, and that the capital of the eastern Shan States had been liberated from "the enemy". He also announced that the new name of the eastern Shan States - that is, Shan State east of the Salween - would be "Original Thai State". Thailand's acquisition of these territories, together with the return of the northern Malay states of Kelantan, Trengganu, Perlis and Kedah which King Chulalongkorn had ceded to the British in 1909, was confirmed by treaty with Japan in August, 1943.

Meanwhile, in Shan State itself, the KMT soldiers withdrew to the hills and forests surrounding Kengtung, whilst the Thais set up a basic local administration in the city. Although the onset of the rainy season in mid-1942 brought a halt to the fighting in the area, it only increased the hardships the Thai troops had to suffer. They were seriously deficient in food and medical supplies, so deaths from malaria and dengue fever far exceeded those in battle. Phibun eventually turned his attention to the problem in January, 1943, when he ordered ten tons of quinine to be sent to the Northern Army.

When Phibun actually visited the north some weeks later, he sent orders flooding back to Bangkok for uniforms, staff officers, sugar, money, doctors and a hundred ox-carts of bananas to be sent to the troops in Shan State. With Japanese backing, he also ordered the construction of hundreds of kilometres of unsurfaced roads to link Chiangmai with Shan State - the present northern loop road from Chiangmai to Mae Hong Son through the settlement of Pai dates from this period.

By this time Phibun and his war cabinet were becoming distinctly uneasy, however. January, 1943 - the same month in which Phibun travelled north - brought news of shattering German defeats at Stalingrad and in North Africa. These were first clear signs that Phibun might have led Thailand into the war on the wrong side. He responded by banning all aliens from residing in Thailand's six northern provinces. Meanwhile the Northern Army continued to announce new victories - spurious claims, treated with scepticism by most Thais, who were well aware that the Japanese had already completed the conquest of Burma.

For the remainder of the war Shan State remained a largely forgotten backwater. Those Thai troops who fell ill and were returned to Bangkok for treatment were shocked that nobody seemed to know or care about the hardships the Northern Army was suffering. Meanwhile the surviving forces of Chiang Kai-shek's KMT 93rd Division hid out in the jungles, occasionally clashing with Japanese forces who had followed the Thais into Shan State and were now behaving with their usual bestiality, completely destroying, for example, the prosperous Chinese Muslim settlement at Panglong, butchering ethnic Chinese, and making it quite clear to the dispirited Thais just who the masters of "Original Thai State" really were.

Meanwhile, back in Bangkok, the Thai authorities were understandably anxious to placate the victorious Allies. Phibun had started out with the stated objective of ensuring that, whoever won the war, Thailand would be on the victorious side. In this, as in so much, he had miscalculated badly. Early in 1944 the British moved to the offensive on the Burma front. Thailand - and especially the Klong Toey docks at Bangkok - came under increasingly frequent bombing raids, supplies were short, the Japanese arrogant and increasingly harsh in their treatment of their Thai "allies".

At home, Phibun was increasingly disliked not just for involving Thailand in an unpopular war and for the rampant inflation, but also for his unpopular domestic policies - his attempts to simplify Thai spelling, to enforce unpopular dress codes, and to forcibly assimilate Thailand's various cultural minorities. On July 24, 1944, taking advantage of Tojo's fall from power a week earlier in Tokyo, an alarmed Thai legislature refused to pass two government bills, and Phibun - widely regarded as Tojo's protégé - was forced to resign.

His successors, under the nominal leadership of Khuang Aphaiwong but strongly influenced by the Free Thai movement of Pridi Phanomyong, were well informed about Allied wartime thinking on the desirability of punishing Thailand for its alliance with Japan. Britain, in particular, sought to impose retribution and controls on Thailand which would reduce the country to near-protectorate status.

In an attempt to forestall this eventuality, the post-Phibun Thai authorities discreetly contacted the Allies and let it be known that they were prepared to turn against their former Japanese partners whenever the Allies gave the word. They also made it quite clear to the British that they renounced all claim to Shan State and northern Malaya, and that they would return these territories to Britain immediately on the cessation of hostilities. Despite these gestures, the British were not disposed to treat the Thais leniently. They felt stabbed in the back by Japan's use of Thai territory to invade Burma and Malaya, and only strong American pressure prevented a vengeful Churchill from implementing punitive measures against the Thais.

Meanwhile, in distant Shan State, Thailand's Northern Army remained in occupation of Kengtung and the surrounding areas until Japan's unexpectedly swift surrender following the nuclear destruction of Hiroshima and Nagasaki in August, 1945. Even before this time some Thai troops had been straggling back to northern Thailand. With the surrender and departure of their Japanese allies, most returned home, though some stayed on amongst their Shan fellows, married, and settled down in Kengtung. The descendants of some of these soldiers still live in Shan State today.

Interestingly, elements of the KMT 93rd Division also stayed on, allying themselves first with new Nationalist refugees from China following the communist seizure of power in 1949. After being driven out of Burma in 1956, some eventually settled in the 93rd Division's final base camp at Doi Mae Salong, in Chiangrai Province, where they and their descendants remain to this day.

Yah, while IJA could board TSR trains back to BKK before going back to Japan, RTA men in Kentung and Shan state had to walk barefoot with ragged uniforms and Malaria in their blood to take Army trains in Phitsanuloke since there was no train in Lampang (the dropping point to Chiang Rai and Shan State).

Durign the fighting, Phayp Army has created the 17th Inf. Reg. (Battelfield) to help the situation which consisted of

1. The 32nd Inf. Bat. from Nakhon Sawan - taken from the 2nd Inf. reg.
2. The 35th Inf. Bat. from Chiang Mai
3. The 39th Inf. Bat. from Nakhon Srithammaraj
Note: the regular HQ for the 17th Inf. Reg.) - leaving the 40th Inf. Bat. (Trang) to protect
the Reg. HQ in Nakhon Srithamaraj.

In 1942, RTA decided to dissolve the 15th Inf. Reg. in Rajburi and designated the 37th Inf. Bat. (Rajburi)
and the 45th Inf. Bat. (Phetburi) to be under the jurisdiction of the 2th Inf. Reg. - Leaving ONLY the 38th Inf. Bat.
to Protect Chumporn

In 1943, RTA has created The 2nd Army (Lopburi) which consisted of
- the 1st Div (Chiang Rak) consisted of
-the 1st Inf. Reg.
- The 1st Inf. Bat. (Royal Guard) (BKK)

-the 2nd Inf. Reg.
- The 2nd Inf. Bat. (BKK)
- The 7th Inf. Bat. (BKK)
- The 37th Inf. Bat. (Rajburi)
- The 45th Inf. Bat. (Phetburi)
- 1st Cavalary Bat. (Moved out of Phayap Army after dissolvign the 12th Cal. Reg)

- the 66th Inf. Bat. - from Youth Army Unit (Chula & Thammasart) - (Nakhon Sawan)
-the 67th Inf. Bat. -from Youth Army Unit (Chula & Thammasart) - (Tak)

This implied that ONLY the 33th Inf. bat, (Reserved Forces), the 12th Inf. Reg still in Phayap Army.

The tough weather really a big bane to Cavalry men - to see theri horses perish before the actual fighting - forcing the early dissolution of the Cavalry Division while moving the 35th Cavalry Regimen to Roy Ed and the 1st Cavlary battalion (Royal Guard usign Australan Stallons) back to BKK.

Nevertheless, RTA has created the 11th Heavy Machine Gun Battalion (can use Type 76 Anti Aircraft with Armour Cars) for Phayap Army as the replacement for the struck out Cavalry Unit ... alogn with the 1st Machine Gun Battalion and the 2nd machine Gun Battalion .. alogn with the 27th Artillery bat. anf the 29th Artillery Bat.

In 1944, the 37th Div has been create to Help Serithai which consited of

- the 9th Infantry Regiment (Ubon Ratchathani) - move from Phayap Army

Now, I got some question which may be a thorny problem
DrG wrote:Dear Wisarut,
I see that you are an expert of WW2 Thailand and I would like to ask you, please, a few "juridical" details about Thai occupations.

I have read that in 1943 Thailand "annexed" 4 Malay states and parts of Burma. Is it correct to call them "annexions" or were them just military occupations? Or was Thai civil administration extended to those regions, but without a formal annexion? Have you got any map of Thailand after these annexions/occupations, please? Thank you very much for your attention, best regards,
Not exactly annexation since these 4 melayu state more like military occupation after IJA has transferred the land in question as a goodwill on 20 August 1943 despite of the demand from the Leader to get something like Koh Kong, Mergui-Dawei-Tennisarim or even more Lao area in addition to Lanchang (Xayaburi - Luang Phrabang on the western bank + Champasak) which have significant Thai-Lao ethnic. Since the leader recognize that this 4 melayu state cannot be occupied and integrate like Battambang - Sisophon - Siem Reap, Champasak, and Xayaburi - Luang Phrabang at the long run, 4 Melayu state must be under military control need to set up the Military governors + office of Military governors who have to coordinate with Sultan and Raya ... need to make a political compromise with both IJA in 4 Melayu states along with Raya+Sultan .... as the bureaucrats of 4 melayu state were well-developed by British tuans (British masters) so Military Provincial Governor have no choice but to cooperate and coordinate with the existing bureaucrats while making a contact with Raya and Sultan of 4 Melayu state.

Something to be notice, even though TSR can extend the train service from Hatyai-Sugei Golok route to hat Yai-Tumpat route, TSR were not allow by IJA who control the railway line between Padang besar and Sugei patani to extend the mixed train service of Hatyai-Padang besar to become Hatyai - Sugei Patani ... even rice, food, and luggage without the stamps of "used for Thai military purposes" will be thrown away at padang Besar. Worse, the attempt to issue the invasion notes by Thai armed forces had to be cancelled due to the objection by IJA who insist to use IJA invasion notes. Those unissued invasion notes later being overprinted as "50 Baht" banknotes to alleviate the paper money shortage.

However, the case of Eastern Shan state, it has been done by RTA and RTAF men even Mueang Phan was given by IJA. The eastern shan state bureaucrats were not so well developed so the Military government had more free hands to deal with the administration - they even have to get money to pay the troops by issuing the Invasion notes and run the opium dens with the help from office of Excise Dept as the measure to get paid in Silver Rupees [1 Silver Rupees was 6 Baht in Thai banknotes] or gold sheet [1 Kyat of gold was about 86 Baht then - equal to a sack of sea salt or a price of bride Thai army men had to pay after breaking the virgin of nubile ladies in those area]. Gen Phin Chunhawan, the military governor of Saharat Thai Doem [the name of Eastern shan state area in official record] had to send the request to bureaucrats in BKK to send civil officers to help him run the administration affairs including the education, the internal affairs or so ... For the judges, it has run the War time court with Central Court in Chiang Tung (Kengtung) with power of supreme court during peace time and 3 District courts in Chiang Tung (Kengtung), Mueang Sad, Mueang Hang with the power of district courts during peace time, but the difference was that the right to appeal and sending to supreme court had been suspended due to the Martial law from 25 Jan 1942 to 1 Jan 1946.

ฺBTW, Saharat Thai Doem consisted of 12 districts - with Field Police Officers as the heads of District - as shown in the map
1. Mueang Chiang Tung district
2. Muang Yong
3. Muang Phayak
4. Muang Yoo
5. Muang Ching
6. Muang Ma
7. Muang Yang
8. Muang Khak
9. Muang Len
10. Maung ko
11. Muang Sad
12. Muang Hang

In conclusion - both cases in question are military government run by military governors even the the level of administration are different according to the local situations. ... 42681.html ... index2.htm ... index3.htm

For the State of Kayah, it is referred to Mueang Phan ( which has become a part of Saharat Thai Doem though which had to be returned to British government in Burma-India after Japanese surrender.
For the more exact map, it should be saved to say that this must be referred to the area on the eastern bank of Salaween river though - with exception of Mong Pan [Mueang Phan] - the 13th district of Saharat Thai Doem after the first 12 districts which I have mentioned before.

Sadly, the map I have gotten just show the current districts which did not show the names of some districts which have been merged though. The map which may closed to the original plan may be this one but not very good resolution though. ... %B8%9B.jpg

For the 13 districts of Saharat Thai Doem, I tried to find the current equivalence, and so far I got this since some of those districts have status reduced all the way to village level.

1. Mueang Chiang Tung district - Kengtung District
2. Muang Yong - Mong Yawng Township, Mong Hpayak District
3. Muang Phayak - Mong Hpayak District
4. Muang Yoo -
5. Muang Ching -
6. Muang Ma -
7. Muang Yang - Mong Yang Township - Kengtung District
8. Muang Khak
9. Muang Len -
10. Maung ko -
11. Muang Sad - Mong Hsat District
12. Muang Hang - Mong Hang village, Mong Tong Township - Mong Hsat District -
13. Muang Phan - Mong Pan Township of Langkho District

Map of Shan state and Kaya state will help you a little bit though
