Thai OB resisting Allies at start

[el cid again]

I found something peculiar, which I didn't remember from Neihorster, who does global OBs to a high
(German) standard. But when I checked his site, he picked it up already, and credits his source. Comments
to follow.

BattambangAt dawn the Imperial Guards Division, spearheading the 15th Army, crossed the border into Thailand's recently reclaimed Battambang Province at Tambon Savay Donkeo, Athuek Thewadej District (Russei) of Battambang. The Japanese encountered no resistance, and from Sisophon swung north-westwards into Aranyaprathet (then still a district of Prachinburi Province) along the nearly finished railway link between Aranyaprathet and Monkhol Bourei. (the actual opening date for traffic was 11 April 1942) [5] [6]

[edit] ChumphonThe Japanese 1st Infantry Battalion of the 143rd Infantry Regiment landed at Chumphon on the morning of December 8. They managed to form a perimeter around their landing areas, but were pinned down by determined resistance by Thai Youth Army (the 52nd Youth Army Training Unit, Sriyaphai School) along with the 38th Infantry Battalion and Provincial Police of Chumpon. Fighting ended in the afternoon when the Thais received orders to cease fire. Thai Forces has lost Captain Thawin Niyomsen (the 52nd Youth Army Training Unit - posthumously promoted to Lt. Col.), a few provincial police and a few civilians. [7]

[edit] Nakhon Si ThammaratNakhon Si Thammarat was the site of the Thai Sixth Army Division’s Headquarters and 39th Infantry Battalion. Three Japanese troopships dropped anchor a few kilometres off the coast during the night of December 7. The ships carried the 3rd Infantry Battalion of the 143rd Infantry Regiment, the 18th Air District Regiment along with an army air force signals unit, the 32nd Anti-Aircraft Battalion, and the 6th Labour Construction Company. Shortly after midnight, they began disembarking their troops at Tha Phae canal (AKA Pak Phoon Canal) - North of Camp Vajiravudh.

The landing was made adjacent to the main Thai army camp, Camp Vajiravudh. The Thais, notified earlier of the Japanese invasion at Songkhla, immediately went into action. The battle lasted until midday, when the prime minister’s orders for a cease fire were received. [8]

[edit] PattaniDue to its closeness to the Malayan border, Pattani was the second most important objective of the Japanese 25th Army. The landings were made despite the rough seas and on unsuitable landing grounds. The invaders were effectively opposed by the Thai 42nd Infantry Battalion, Pattani Provincial Police and Thai Youth Army units (the 66th Youth Army Training Unit from Benjama Rachoothit School) until the battalion was ordered to cease fire at midday. The Thai battalion commander, Khun Inkhayutboriharn, was killed in action along with 23 other ranks, 5 Provincial Police, 4 Youth Army members and 9 Civilians.[9]

[edit] Prachuap Khiri KhanMain article: Battle of Prachuab Khirikhan
Prachuap Khiri Khan was home to the Royal Thai Air Force’s Fifth Wing, under the command of Wing Commander M.L. Pravat Chumsai. The Japanese 2nd Infantry Battalion of the 143rd Infantry Regiment landed at 03:00 am, and occupied the town after having crushed police resistance there.

Further landings took place near the airfield to the south. The Japanese laid siege to the airfield, but the Thai airmen along with Prachuap Khirikhan Provincial Police managed to hold out until noon on the next day, when they received orders from the Thai government to cease fighting. The Japanese lost 115 dead according to Japanese estimates and 217 dead and 300+ wounded according to Thai estimates. The Thais lost 18 dead and 27 wounded. [10]

[edit] Samut PrakanThe Japanese 3rd Battalion of the Imperial Guards Regiment landed at Samut Prakan in the early hours of December 8. It was tasked with the capture of Bangkok. The force was met by a small Thai police detachment. Despite a tense confrontation, fighting did not occur and the Japanese subsequently agreed not to enter the Thai capital until formal negotiations were concluded. [11]

[edit] SongkhlaThe port city of Songkhla was one of the main objectives of Yamashita’s 25th Army. The Japanese landings occurred during the early hours of December 8.

Thai garrison at Khao Khor Hong (the 41st Infantry Battalion and the 13th Artillery battalion) immediately occupied positions alongside the roads leading down to Malaya, but were brushed aside into positions the main Japanese advance could ignore. A further clash occurred at Hat Yai. The Thais lost 15 dead (8 KIA from 41st Inf. Bat. and 7 from the 5th Inf. bat.) and 30-55 wounded.

The fighting ceased at noon when orders for an armistice to be arranged was received. [12]

[edit] Surat ThaniA Japanese infantry company from the 1st Battalion of the 143rd Infantry Regiment landed at the coastal village of Ban Don in the early hours of December 8. They marched into Surat Thani, where they were opposed by Royal Thai Police and civilian volunteers. The desultory fighting took place amid a rainstorm, and only ended in the afternoon when the hard-pressed Thais received orders to lay down their arms. The Thais lost 17-18 dead but the injured was not known exactly. [13]

[edit] BangkokWhile police rounded up Japanese residents the Thai cabinet debated its options.[14] Some favoured continued resistance, including the establishment of a government-in-exile, but when Phibun finally returned they relented, and the Thai's caved in to Japan's demands.

[edit] AftermathMain article: Japanese occupation of Thailand
Plaek Pibulsonggram's decision to sign an armistice with Japan effectively ended Churchill's hopes of forging an alliance with Thailand. He also granted Japan permission to use Thailand as a base of operations to invade Malaya. Within hours after the armistice came into effect, squadrons of Japanese aircraft had flown into Songkla airfield from Indochina, allowing them to carry out air raids on strategic bases in Malaya and Singapore from a short distance. At the time of the ceasefire, Great Britain and the United States regarded Thailand as Japanese-occupied territory.[2]

On 14 December, Pibulsonggram signed a secret agreement with the Japanese committing Thai troops in the Burma Campaign. An alliance between Thailand and Japan was formally signed on December 21, 1941. On January 25, 1942, the Thai government declared war on the United States and the United Kingdom. In response, all Thai assets in the United States were frozen by the federal government. While the Thai ambassador in London delivered the declaration of war to the British administration, Seni Pramoj, Thai ambassador to Washington D.C., refused to do so, instead organising a Free Thai movement.[2][15]

I wondered if we can put this in the game. Since I usually play Japan, I did not figure the Allies would
mind having some troops in front of me!

Experiments show that if you set these companies and battalions (and some police platoons) in place to
start - as ALLIED units - but order "withdraw" for 411208 - they will vaporize after a single day. Not
quite the same as a few hours - but close enough.

By carefully rating leaders, I was able to duplicate historical performance. A place with two line battalions
and more gives way - due to weak leaders - but smaller defenses hold - due to good ones. Which implies
there is some merit to the way the system is coded.

Anyway - all this FYI. It is a long way from nothing on the beach as we are used to. Note that my
beaches are mostly defined as Allied already - most of Thailand must be "captured" - and does not contribute
to the Japanese economy or permit air unit transfer - until it is. I have RTA units appear as Axis units only
on 411221 - when they joined the Axis. They also all withdraw on 440622 - when the leader (his name is so
long no one uses it, even in Thailand) was arrested and deposed. Just before that, I have special Free Thai
Army units appear - one is a MP unit modeled on the Kempeitei - its graduation was attended by the IJA
garrison commander. Its MISSION was to overthow the Axis regime! Its COMMANDER was the head of the RTN!
Nothing is as it seems in Thailand. The unit was to be backed up by the RTA Guards Division! But the war
ends before it is able to act.
