The Battle of Prachuab Khrikhan was an early engagement of the Japanese invasion of Thailand in the Southeast Asian theatre of World War II. It was fought on 8-9 December 1941 at the airfield of Prachuap Khiri Khan in Thailand, on the coast of the Gulf of Thailand along the Kra Isthmus. The Japanese meant to use Thailand as a base to strike at British possessions in Burma and Malaya and attacked Thailand without warning.

Battle

Fighting took place at Ao Manao Beach

At about 03:00 on 8 December 1941, the 2nd Battalion, 143rd Infantry Regiment, 55th Division of the Imperial Japanese Army, under the command of Major Kisoyoshi Utsunomiya, began landing troops at Prachuab Khiri Khan. When informed of invasion, Wing Commander Mom Luang Prawat Chumsai of Kong Bin Noi (Squadron) 5 immediately gave orders to resist.^[1]

The units on the airfield were equipped with six heavy and two light machine guns, which they immediately turned against the Japanese troops trying to surround the airfield. The small garrison of pilots and ground crew was reinforced by members of the constabulary and the Yuwachon Thaharn (a quasi-military teenage auxiliary) who had managed to escape from the town of Prachuap Khiri Khan after the Japanese had captured the telegraph office and the police station.

Despite the fact that the Japanese had occupied part of the airfield, Kong Bin Noi 5's pilots attempted to take off at sunrise to bomb and strafe the advancing Japanese.

Chief Warrant Officer Prom Chuwong was first to take off in a Hawk III. However, Japanese ground fire quickly shot him down, killing him. The Japanese shot down two more Hawks as they attempted to take off, killing both pilots, and wounded a third pilot as he brought his Hawk onto the runway. Only one other pilot managed to get airborne. Flying Officer Man Prasongdi took off in a Hawk III armed with four 50 kg bombs and attempted to attack Japanese transports in Ao Manao harbor. However, he could not locate them due to heavy fog and rain.^[2]

By 08:00, most of the northern hangars were in Japanese hands. The Thais smashed the instruments of the isolated airfield control tower and set fire to it, as the runways were abandoned. A new perimeter was set up and the withdrawing airmen were covered by a machine gun positioned in the clubhouse's tennis court, manned by Airmen Singto Saensukh and Kasem Wongkangya. The machine gun kept firing throughout the morning and into the afternoon.

Pilot Officer Somsri Suchrittham and his men, whose strength was now around thirty, were forced to withdraw when their northern flank was threatened by the abandonment of the runways.

Having successfully secured the beachhead, the Japanese proceeded to occupy what was left of the hangars and runways, and reinforcements, including artillery and ten tanks, were landed from the transports.

The families of the airmen took refuge in the guesthouses on Mount Laum Muak. The evacuation of the living quarters was supervised by Pilot Officer Phol Thongpricha.

Another position was set up by defenders, who divided themselves into three groups. One group was stationed by the guest houses on Prachuap Bay and fired on anything coming up the road from the guard house. A second group, under the immediate command of Wing Commander Prawat, placed itself in the area around the command and administrative buildings. The final group occupied houses facing Manao Bay. These two groups fired on the approaches from the hangars and the runways.

Fighting continued into late evening, but with lessening intensity. The machine gun at the tennis court held back the Japanese, while a light machine gun was held in reserve and moved to plug gaps in the perimeter.

Rumours that Royal Thai Navy sailors were fighting their way through to relieve the airmen kept up Thai hopes through the night. Ammunition was low, and at one point the airmen actually fired blank rounds at the Japanese.

The following morning, the exhausted Thais received a telegram from the Ministry of the Interior, brought in by a postman during a lull in the battle. The telegram ordered the defenders to cease fighting, as an armistice had been arranged by the government.^[3]

However, the Thais felt this was a trick by the Japanese and continued to resist. The infuriated invaders now mounted assaults with renewed vigor. The defenders were slowly pushed back. About this time, the lone machine gun in the tennis court was taken out, both gunners severely wounded.

By 10:00, with the Japanese closing in, Wing Commander Prawat ordered the command building to be burned, along with all military documents. As flames engulfed the building, Flying Officer Prayad Kanchonwiroj, the senior medical officer, ordered the hospital building evacuated and set on fire.

Wing Commander Prawat ordered all officers to save a bullet for themselves and said those who wanted to were free to try to break out on their own. The others, including the wounded, were to fall back on Mount Laum Muak.

At noon, a civilian car with a small white flag arrived. It contained a number of Thai government officials, including the province's undersecretary, Jarunphan Isarangun na Ayutthaya. Jarunphan handed Wing Commander Prawat a direct order from the prime minister, Field Marshal Phibunsongkhram, telling him to cease resistance immediately. Fighting officially ended at 12:35 on 9 December 1941.

Losses

The Thais suffered 38 dead and 27 wounded, including airmen, police, and civilians. Wing Commander Prawat's pregnant wife was among the dead, killed by a stray bullet. Japanese sources stated that the Japanese suffered 115 dead. However, Thai estimates of Japanese losses were put at 217 dead and more than 300 wounded.^[4]

Memorials

A monument to the Thai defenders stands on the Royal Thai Air Force base at Prachuap Khiri Khan. Each December a memorial is held to honor those who fought and died defending their country from invasion.^[5]
