Battle of Kujin


The Battle of Kujin, also known as the Battle of the Broken Bridge, took place during the United Nations Command offensive towards the Yalu River, which followed the North Korean invasion of South Korea at the start of the Korean War. The battle was fought between Australian forces from 3rd Battalion, Royal Australian Regiment and elements of the 17th Tank Brigade of the Korean People's Army over a key bridge across the Taeryong River near Kujin, North Korea. On 25 October the 27th British Commonwealth Brigade had resumed their advance towards Pakchon after crossing the Chongchon River, with 3 RAR as the lead battalion. Arriving at Kujin, the Australians discovered that the centre span of the concrete bridge had been demolished by KPA engineers, blocking their passage across the river. A platoon-sized reconnaissance patrol crossed the river using debris from the destroyed span; however, it was soon forced to withdraw by KPA holding the high ground. Airstrikes and artillery fire were subsequently called in at 17:15 by the Australians as they prepared to conduct an assault.
At 19:00 that evening, following the clearance of nearby Pakchon by D Company 3 RAR, the Australians sent two companies across the river to establish a bridgehead and prevent the KPA from consolidating their position on the western bank. A and B Companies subsequently established defensive positions on either side of the road. Shortly afterwards KPA forces were detected forming up for an assault on the right flank against B Company, and these preparations were broken up with mortars. The KPA then engaged the forward Australian companies with mortar fire which was largely ineffective. However, by 22:30 KPA activity increased significantly, with heavy small arms fire causing a number of casualties among the Australians which perilously had to be evacuated under fire by boat across the fast flowing tidal river. Further artillery support was called in by the Australians at 23:00 in response to renewed concentrations by the KPA in preparation for an assault. Meanwhile, the Australians sent another platoon across the river to reinforce the companies on the western bank.
At 04:00 on 26 October the KPA counterattacked A and B Companies, supported by two T-34 tanks. In the ensuing fighting a convoy of KPA vehicles, including a tank, two jeeps, a motorcycle and about 60 infantry moved down the road towards A Company with the intention of re-occupying the ridges overlooking the river crossing. The Australians ambushed the convoy at close range with small arms fire and mortars, forcing the KPA to flee after abandoning their vehicles with only the tank successfully shooting its way out. Later another T-34 tank and supporting infantry pressed to within of the B Company headquarters, before stopping and taking up a position between the ridges unaware of the location of the Australians. By dawn the Australians were still in possession of the bridgehead. At 07:00, a further airstrike was called in on the KPA holding the ridges to the west of the 3 RAR positions. With the way reported clear, C and D Companies crossed the river from the eastern bank later that morning. The battle continued during the morning; however, by 12:00 the KPA finally withdrew, abandoning the bridge to the Australians.

Background

Military situation

The Korean War began early in the morning of 25 June 1950, following the surprise invasion of the Republic of Korea by its northern neighbour, the communist Democratic People's Republic of Korea. Numerically superior and better equipped, the KPA crossed the 38th Parallel and rapidly advanced south, easily overcoming the inferior Republic of Korea Army. In response, the United Nations decided to intervene on behalf of South Korea, inviting member states to send forces to restore the situation. As a consequence, American ground forces were hastily deployed in an attempt to prevent the South Koreans from collapsing; however, they too were understrength and poorly equipped, and by early August had been forced back by the KPA to an enclave around Pusan, known as the Pusan Perimeter. Key US allies—Britain, Canada and Australia—also committed forces, although these were initially limited to naval contingents and were largely viewed as token efforts in the US. Under diplomatic pressure the British agreed to deploy an infantry brigade in July, and would later dispatch a second brigade as the crisis worsened. The Canadians also agreed to provide an infantry brigade, although the first battalion would not arrive until December 1950. A total of 21 UN member states eventually contributed forces.
Australia was one of the first nations to commit units to the fighting, playing a small but sometimes significant part in the UN forces, which was initially led by General Douglas MacArthur. Forces deployed in Japan as part of the British Commonwealth Occupation Force formed the basis of the Australian response, with P-51 Mustang fighter-bombers from No. 77 Squadron RAAF flying their first missions on 2 July, while the frigate and the destroyer were also committed to naval operations. During this time the 3rd Battalion, Royal Australian Regiment, which had been preparing to return to Australia prior to the outbreak of the war, remained in Japan; however, on 26 July the Australian government announced that it would also commit the understrength and poorly equipped infantry battalion to the fighting, following a period of preparation. Training and re-equipment began immediately, while hundreds of reinforcements were hastily recruited in Australia as part of K Force; they soon began arriving to fill out the battalion. The battalion's commanding officer, Lieutenant Colonel Floyd Walsh, was subsequently replaced by Lieutenant Colonel Charles Green. An officer with extensive operational experience fighting the Japanese in New Guinea during the Second World War, Green took over from Walsh due to the latter's perceived inexperience.
On 23 September 1950, 3 RAR embarked for Korea, concentrating at Pusan on 28 September. There it joined the British 27th Infantry Brigade, a garrison formation hurriedly committed from Hong Kong by the British as the situation deteriorated around the Pusan Perimeter in late August to bolster the US Eighth Army under Lieutenant General Walton Walker. Commanded by Brigadier Basil Coad, the brigade was renamed the 27th British Commonwealth Brigade and consisted of the 1st Battalion, Argyll and Sutherland Highland Regiment, the 1st Battalion, Middlesex Regiment and 3 RAR. Understrength, the two British battalions had each mustered just 600 men of all ranks, while the brigade was also short on transport and heavy equipment, and had no integral artillery support, for which it would rely entirely on the Americans until the 16th Field Regiment, Royal New Zealand Artillery arrived in January 1951. As such, with a strength of nearly 1,000 men, the addition of 3 RAR gave the brigade increased tactical weight as well as expediently allowing the Australians to work within a familiar organisational environment, rather than being attached to a US formation. Also under the command of the brigade were a number of US Army units, including 155 mm howitzers from the 90th Field Artillery Battalion, M4 Sherman tanks from 89th Tank Battalion and a company from the US 72nd Combat Engineer Battalion.

Prelude

Opposing forces

By the time 3 RAR arrived in the theatre, the KPA had been broken and were in rapid retreat, with MacArthur's forces conducting a successful amphibious assault at Inchon and breakout from the Pusan Perimeter on the southern tip of the Korean peninsula. A steady advance began, driving the North Koreans northwards towards the 38th Parallel. The 27th British Commonwealth Brigade was airlifted from Taegu to Kimpo Airfield north of Seoul on 5 October; however, its vehicles had to move by road, driving, and did not arrive until 9 October. It was subsequently attached to the US 1st Cavalry Division, under the command of Major General Hobart R. Gay. On 16 October the brigade took over from the US 7th Cavalry Regiment as the vanguard of the UN advance into North Korea, its axis intended to take it through Kaesong, Kumchon County and Hungsu-ri to Sariwon, then through Hwangju to the North Korean capital of Pyongyang. Although the KPA had suffered heavily in the preceding weeks, they continued to resist strongly, while a lack of accurate maps and the narrowness of the roads made rapid movement difficult for the advancing UN forces. During this time 3 RAR had a platoon of American M4 Sherman tanks attached and a battery of field guns in direct support.
The 27th British Commonwealth Brigade subsequently moved from Kumchon, with the Argylls capturing Sariwon on 17 October, killing 215 KPA and taking many prisoners for the loss of one man killed and three wounded. The brigade then passed to the command of the US 24th Infantry Division on 21 October, under the overall command of Major General John H. Church, while the US 1st Cavalry Division remained in Pyongyang to complete its capture. The 27th British Commonwealth Brigade was subsequently ordered to seize Chongju. Consequently, the brigade continued to advance north with little respite, and on 22 October the Australians fought their first major action at Yongju, killing 150 KPA and capturing 239 of the brigade's 800 prisoners, for the loss of seven men wounded. Intending to defeat the KPA and bring the war to a close, the UN forces pushed towards the Yalu River, on the Chinese border. Resistance continued to be met as the brigade crossed the Chongchon River however, and they now moved towards Pakchon. On 24 October, MacArthur had removed all restrictions on the movement of his forces south of the Yalu River and prepared for the final phase of the UN advance, defying a directive of the US Joint Chiefs of Staff and risking Chinese intervention in support of North Korea.
With the Middlesex in the vanguard, the lead elements of the 27th British Commonwealth Brigade successfully crossed the Chongchon unopposed at Sinanju on 24 October using assault boats. The British battalion then established a defensive position overlooking the main bridge in preparation for the remainder of the brigade to continue the advance the following day. However, both the road and rail bridges at Sinanju had previously been damaged and they were subsequently found to be unsuitable for use by vehicles and armour, while the tidal current also prevented the rafting of even light vehicles by the American engineers attached to the brigade. Meanwhile, the road bridge at Anju, east, was also found to be damaged by ROK 1st Infantry Division when it entered the town. Following repairs the bridge was made available to the 27th British Commonwealth Brigade's light wheeled vehicles on 25 October, while the accompanying Sherman tanks located a ford upstream, and were able to cross the Chongchon at that point. With winter approaching, the British and Australians encountered the first of the cold weather as the temperature began to drop well below freezing at night. Consequently, prior to leaving Sinanju, purpose-designed American cold-weather clothing was issued; however, with stocks in short supply only a few of the men received the equipment, even after a second issue was arranged several days later.
