Major confrontation during the Chinese Spring Offensive of the Korean War
the similarly named battle during the [[Japanese invasions of Korea (1592–1598)

The Battle of the Imjin River , also known as the Battle of Solma ri or Battle of Gloster Hill (글로스터 고지 전투) in South Korea, or as Battle of Xuemali in China, took place 22–25 April 1951 during the Korean War. Troops from the Chinese People's Volunteer Army (PVA) attacked United Nations Command (UN) positions on the lower Imjin River in an attempt to achieve a breakthrough and recapture the South Korean capital Seoul. The attack was part of the Chinese Spring Offensive, the aim of which was to regain the initiative on the battlefield after a series of successful UN counter offensives in January–March 1951 had allowed UN forces to establish themselves beyond the 38th Parallel at the Kansas Line. The section of the UN line where the battle took place was defended primarily by British forces of the 29th Infantry Brigade, consisting of three British and one Belgian infantry battalions (Belgian United Nations Command) supported by tanks and artillery. Despite facing a greatly numerically superior enemy, the brigade held its general positions for three days. When the units of the 29th Infantry Brigade were ultimately forced to fall back, their actions in the Battle of the Imjin River together with those of other UN forces, for example in the Battle of Kapyong, had blunted the impetus of the PVA offensive and allowed UN forces to retreat to prepared defensive positions north of Seoul, where the PVA were halted. It is often known as the "Battle that saved Seoul." "Though minor in scale, the battle's ferocity caught the imagination of the world", especially the fate of the 1st Battalion, The Gloucestershire Regiment, which was outnumbered and eventually surrounded by Chinese forces on Hill 235, a feature that became known as Gloster Hill. The stand of the Gloucestershire battalion, together with other actions of the 29th Brigade in the Battle of the Imjin River, has become an important part of British military history and tradition.

Following the Soviet backed North Korean invasion of South Korea on 25 June 1950, a UN counter offensive had reached the North Korean border with China. On the premise of fearing for its own security, China committed troops it had already moved to the border and began three offensives between 3 November 1950 and 24 January 1951 which pushed the UN forces south of the original border between North and South Korea along the 38th Parallel and captured Seoul. A fourth offensive in mid February was blunted by UN forces in the Battle of Chipyong ni and Third Battle of Wonju. At the end of February the UN launched a series of offensive operations, recapturing Seoul on 15 March and pushing the front line back northwards. In early April Operation Rugged established the front in a line that followed the lower Imjin river, then eastwards to the Hwacheon Reservoir and on to the Yangyang area on the east coast, known as the Kansas Line. The subsequent Operation Dauntless pushed out a salient between the Imjin river as it dog legged north and the Hwacheon Reservoir, known as the Utah Line.

On 22 April the front line in the west along Lines Kansas and Utah was held by the United States Army (US) I Corps comprising, from west to east, the South Korean Republic of Korea Army (ROK) 1st Division, the US 3rd Division with the attached British 29th Brigade, the US 25th Division with the attached Turkish Brigade and the US 24th Division. The 29th Infantry Brigade, commanded by Brigadier Tom Brodie, consisted of the 1st Battalion Gloucestershire Regiment (Glosters), under Lieutenant Colonel James P. Carne; the 1st Battalion Royal Northumberland Fusiliers (Fusiliers), under Lieutenant Colonel Kingsley Foster; the 1st Battalion Royal Ulster Rifles (Rifles), under the temporary command of Major Gerald Rickord; and the Belgian Battalion, under Lieutenant Colonel Albert Crahay (700 men), to which Luxembourg's contribution to the UN forces was attached. The brigade was supported by the 25 pounders of 45 Field Regiment Royal Artillery (RA) commanded by Lieutenant Colonel MT Young, the 4.2 inch mortars of 170 Independent Mortar Battery RA, the Centurion tanks of C Squadron 8th King's Royal Irish Hussars under the command of Major Henry Huth, and by 55 Squadron Royal Engineers. The four battalions of 29th Brigade covered a front of 12 mile (19 km). Gaps between units had to be accepted because there was no possibility of forming a continuous line with the forces available. "Brigadier Brodie determined to deploy his men in separate unit positions, centred upon key hill features" On the left flank, the Glosters were guarding a ford over the Imjin 1 mile (2 km) east of the ROK 1st Division; the Fusiliers were deployed near the centre, around 2 mile (3 km) northeast of the Glosters; the Belgians, occupying a feature called Hill 194 on the right, were the only element of the 29th Brigade north of the river. Their connection with the rest of the brigade depended on two pontoon bridges about 0.5 mile (1 km) apart. These bridges connected the Belgians with Route 11, the 29th Brigade's main line of supply and communication. The Rifles served as the brigade's reserve and were deployed along Route 11. Extensive defensive preparations were not completed because the British expected to hold the position for only a short time. Neither minefields, deeply dug shelters nor extensive wire obstacles had been constructed. The British position on the Imjin river "was deemed safe" but vulnerable in case of an attack.

The commander in chief of the PVA and North Korean Korean People's Army (KPA) forces in the Field, Marshal Peng Dehuai, planned to "wipe out the American 3rd Division the British 29th Brigade and the 1st Division of the Republic of Korean Army after this we can wipe out the American 24th Division and 25th Division", and promised the capture of Seoul as a May Day gift to Mao Zedong. To achieve the objective Peng planned to converge on Seoul with three PVA army groups and a KPA corps; a total strength of some 305,000 men. The III and IX Army Groups were to attack the right flank of the US 3rd Division and the 24th and 25th Divisions on the Utah Line, east of the Imjin where it turned north. The XIX Army Group on the PVA right flank, west of the Imjin river where it turned north, were to attack the remainder of the 3rd Division and the ROK 1st Division. On the XIX Army Group front, the KPA I Corps and PVA 64th Army would attack the ROK 1st Division, while the 63rd Army would attack on their left, pitting it against 29th Brigade. The 63rd Army comprised three divisions, the 187th, 188th and 189th, with each division comprising three regiments, each of which comprised three battalions. Some 27,000 men in 27 battalions would be attacking 29th Brigade's four battalions, albeit in echelon, one division after the other.

The battle opened on the night of 22 April 1951. A PVA patrol on the north bank of the river moved around the Belgians on Hill 194 and continued to advance east towards the two bridges on which the Belgians depended. Elements of the 29th Brigade's reserve, the 1st RUR, were deployed forward at about 22:00 to secure the crossing but were soon engaged by PVA forces trying to cross the river. The Royal Ulster Rifles were unable to secure the bridges. This development meant that the Belgian battalion on the north bank of the river was in danger of being isolated from the rest of the 29th Brigade. PVA forces following the initial patrol either attacked the Belgian positions on Hill 194 or continued their advance towards the bridges. Those who were able to cross the Imjin attacked the Fusiliers' right rear company, Z Company, on Hill 257, a position close to the river and almost directly south of the crossings. Further downstream, PVA forces managed to ford the Imjin and attacked the Fusiliers' left forward company, X Company, on Hill 152. The retreat of X Company from Hill 152 had serious consequences for Y Company, which occupied the right forward position of what can be described as a squarish fusilier position marked out by four widely spaced company perimeters at the corners. Although Y Company was not attacked directly, PVA forces threatened its flanks by forcing Z and X Companies from their positions. After unsuccessful British attempts to regain those lost positions on Hill 257 and 194, Y Company's position was abandoned, the retreat being covered by C Squadron, 8th Hussars. On the left of the brigade's line, a patrol of 17 men from the Glosters' C Company lying in wait on the river bank repulsed three attempts by a battalion of the 559th Regiment, 187th Division to cross the river, eventually retiring without loss when their ammunition ran low and assaulting troops finally gained the opposite bank. During the night the Glosters' A and D Companies were attacked, and by 07:30 A Company, outnumbered six to one, had been forced from its position on Castle Hill. An attempt to retake it failed, during which Lieutenant Philip Curtis single handedly destroyed a PVA machine gun position with a grenade but was himself killed by a burst of machine gun fire in the process. He was posthumously awarded the Victoria Cross.

Continued PVA pressure on the UN forces along the Imjin prevented a planned attack by the US 1st and 3rd Battalions, 65th Infantry, to relieve the Glosters. When two further attempts by a tank troop to link up with the Glosters failed, Brodie left the decision to Carne whether to attempt a break out or surrender. No further attempts to relieve the Glosters were undertaken because, at 08:00 on 25 April, US I Corps issued the order to execute Plan Golden A, which called for a withdrawal of all forces to a new defensive position further south. In accordance with orders issued by I Corps, the Fusiliers, Rifles and Belgians, supported by the tanks of the 8th Hussars and the Royal Engineers of 55 Squadron, withdrew to the safety of the next UN position. The Belgians occupied blocking positions west and southwest of the 29th Brigade's command post in order to allow the other units of the brigade to fall back through the battalion's positions. The withdrawal under intense enemy pressure was made even more difficult by the fact that PVA forces dominated parts of the high ground along the line of retreat; they were able not only to observe any movements by the 29th Brigade, but also to inflict heavy casualties on the retreating units. Among those killed was the commanding officer of the Fusiliers, Lieutenant Colonel Foster, who died when his jeep was hit by PVA mortar fire. In the words of Major Henry Huth of the 8th Hussars, the retreat was "one long bloody ambush". When B Company of the Ulsters, which had acted as rearguard during the retreat, reached the safety of the next UN line, all elements of the 29th Brigade except for the Glosters had completed the withdrawal.

The Glosters' situation on Hill 235 made it impossible for them to join the rest of the 29th Brigade after it had received the order to retreat. Even before the failed attempts to relieve the battalion on 24 April, B and C Companies had already suffered such heavy casualties that they were merged to form one company. Attempts to supply the battalion by air drop were unsuccessful. Despite their difficult situation, the Glosters held their positions on Hill 235 throughout 24 April and the night of 24/25 April. In the morning of 25 April, 45 Field Regiment could no longer provide artillery support. Since Brodie had left the final decision to Carne, the Glosters' CO "gave the order to his company commanders to make for the British lines as best as they could" on the morning of 25 April. Only the remains of D Company, under the command of Major Mike Harvey, reached the UN lines after several days. The rest of the battalion surrendered and 459 of them were taken prisoner, including Carne.

Had the PVA achieved a breakthrough in the initial stages of their assault, they would have been able to outflank the ROK 1st Division to the west and the US 3rd Infantry Division to the east of the 29th Brigade. Such a development would have threatened the stability of the UN line and increased the likelihood of success for a PVA advance on Seoul. Although the PVA benefited from the brigade's scattered deployment and lack of defensive preparations, they were nevertheless unable to take the positions before UN forces could check further advances. In three days of fighting, the determined resistance of the 29th Brigade severely disrupted the PVA offensive, causing it to lose momentum, and allowed UN forces in the area to withdraw to the No Name Line, a defensive position north of Seoul, where the PVA/KPA were halted. The scope and the outcome of the Imjin River engagement have been subjected to several interpretations according to different historiography traditions. According to official Chinese history, the elimination of the 1st Battalion, Gloucestershire Regiment by the Chinese 63rd Army is considered to be an important victory, although the failure of the 64th and the 65th Army to eliminate the entire British 29th Independent Infantry Brigade and capture Seoul due to the defense of ROK 1st Infantry Division was a serious setback. On the other hand, the South Korean contributions to the Imjin River battle are only recorded in sparse detail by the official South Korean history, but historian Allan R. Millet has argued that the ROK 1st Infantry Division's performance in battle demonstrated the potential of South Korean armed forces, in the wake of serious failures during the period of 1950–51. In British Empire countries, the engagement has been interpreted as the 29th Brigade's sacrifice, against impossible odds when facing the Chinese 63rd Army, which ultimately prevented the Chinese from capturing Seoul. Regardless of the interpretations, independent research from historians Zhang Shu Guang and Andrew Salmon concluded that the actions of the 29th Brigade had disrupted the Chinese advance sufficiently to affect the outcome of the First Chinese Spring Offensive.
