al-sized Chinese attack against the US 1st Marine Division, with diversionary assaults mounted against the Australians. With the peace talks in Panmunjom reaching a conclusion, the Chinese had been eager to gain a last-minute victory over the UN forces and the battle was one of the last of the war.

During the action the Chinese had attempted to make a breakthrough to the Imjin River

s, 2 RAR successfully thwarted both assaults, holding a key position known as The Hook. Later, it was estimated that Chinese casualties numbered between 2,000 and 3,000 killed, with the majority of them inflicted by the New Zealand gunners. Meanwhile on the left flank, the US Marines had endured the brunt of the attack, repelling the Chinese onslaught but suffering a number of casualties in the process. Only a few hours later the Armistice Agreement was signed, ultimately ending the war. Both sides subsequently withdrew 2 kilometres (1.2 mi) within 72 hours to create a 4 kilometres (2.5 mi) demilitarised zone.

Background

Following the Battle of Maryang San in early October 1951 the 28th British Commonwealth Brigade remained in defence for the remainder of the month. Amid heavy fighting on the afternoon of 4 November the Chinese recaptured Hill 317, which was by then held by the 1st Battalion, King's Own Scottish Borderers

. The brigade re-entered the line on 30 June and 1 RAR spent the following fourteen weeks patrolling, ambushing and raiding, before the 28th British Commonwealth Brigade again went into reserve on 5 October. The brigade returned to the Jamestown Line in early November, with 1 RAR taking over the defences on Hill 355 from the Canadians. The Australians were subsequently forced to clean up large quantities of rubbish left by the Canadians as well as repairing and camouflaging the defences which had recently been attacked by the Chinese. 1 RAR implemented an aggressive patrol program in an effort to regain control of no-man's land from the Chinese, which had been allowed to establish hides close to the perimeter. A number of Chinese outposts were subsequently destroyed during raids of up to company-size.

3 RAR took over the defences on Hill 355 on 28 December 1952 and remained there until the 1st Commonwealth Division went into reserve at the end January 1953. On 21 March, 1 RAR was replaced in Korea by the 2nd Battalion, Royal Australian Regiment

 (2 RAR), after nearly twelve months operational service. Heavy fighting occurred in March, with the Chinese moving back over to a limited offensive in the US I Corps sector, in an attempt to regain the initiative following the winter. Heavy fighting occurred around The Hook, which was by then held by the US 2nd Division following the relief of the 1st Commonwealth Division, the Old Baldy and Porkchop Hill features held by the US 7th Division and in the western sector held by the US 1st Marine Division around the Vegas and Reno outposts. Peace talks finally resumed at Panmunjom on 6 April and an agreement was soon made to exchange sick and wounded prisoners. Consequently 648 UN and 6,670 Chinese and North Korean prisoners were subsequently repatriated as part of Operation Little Switch on 20 April, including five Australians. For a while the tempo of operations slackened, returning to the small-scale raids and probes of the winter months. Yet during the final three months of the war the Chinese launched a series of offensives prior to the signing of a ceasefire agreement.

The 28th British Commonwealth Brigade subsequently occupied the north-eastern sector. 2 RAR occupied Hill 159 during 5 May to 16 June, while 3 RAR held Hill 355 during the period 7–27 May. 3 RAR then relieved 2 RAR on 16 June, and remained on Hill 159 until 10 July. Meanwhile, The Hook was a key position on the left flank of the line held by the 1st Commonwealth Division, and was the division's most threatened sector on the Jamestown Line. Held by the 29th British Infantry Brigade, the position consisted of a group of hills west of the Samichon River which dominated the Imjin River

Following another Chinese assault on 9 July the Americans again counter-attacked, yet neither side gained a clear advantage. The following day the Chinese launched a series of company and battalion-sized assaults, but were repulsed. Yet, with the Americans unprepared to accept further casualties for limited tactical gain, they evacuated Porkchop Hill on 11 July.

Prelude

The peace talks resumed in early July as Rhee's position apparently softened, yet this proved the impetus for a final Chinese offensive as they sought to further influence the talks and improve their defensive positions at the same time.

 had been practically destroyed, exposing serious weaknesses despite two years of American training. The South Koreans fell back and the UN line was penetrated to a depth of 9.7 kilometres (6 mi). Only American intervention restored the situation and ultimately nine South Korean and US divisions were required to stem the Chinese offensive and regain some of the lost ground. Following a counter-attack by ROK II Corps a new defensive line was established south of the Kumsong River. Meanwhile, in conjunction with the main offensive at Kumsong, the Chinese 19th Army Group had conducted a series of limited offensives against US I Corps, with the 46th Army conducting five separate assaults against the US 1st Marine Division from 25 June to 27 July. Nonetheless, Chinese losses were heavy and they sustained more than 28,000 casualties for only temporary gain.

A Company occupied Hill 146, on the boundary with 2 RAR, B Company held the south-eastern tip of the ridge, and C and D Companies were held in reserve. British Centurion tanks were also deployed forward to support the Australians. Directly confronting the Australians on The Hook was the 137th Division of the Chinese 46th Field Army which had been in the line since February 1953, under the command of Cheng Dengzhi.According to the Australian official history the Chinese 47th Field Army was facing the 1st Commonwealth Division, having relieved the 39th Army

 on the front line in late-October 1952. However the official Chinese records indicate that the 47th Field Army was pulled off the front line and put into reserve status by May 1953. See and .


The positions occupied by the Australians had been badly damaged by the Chinese assaults and bombardments in May and June, and recent rain had also collapsed some trenches and weakened many of the wire obstacles. Yet the extensive tunnel system—dug by the Canadians the previous winter—remained intact and afforded some protection. Efforts to repair the defences and assert control in no man's land began immediately, with an aggressive patrolling program by the Australians leading to numerous clashes with Chinese patrols, while they also endured heavy shelling during this time. By day it was hot and humid making conditions in the bunkers uncomfortable, while by night the defenders worked hard digging, wiring and laying minefields. However, the Chinese focused most of their attention on the US 7th Marine Regiment, which was occupying positions south-west of 2 RAR after having relieved the Turkish Brigade

Light mortaring hit 2 RAR on 11 July, while one 3 RAR soldier was killed instantly by a 76 millimetres (3 in) shell when he was observed walking along the crest-line by a Chinese position less than 200 metres (218.7 yd) from the Australian perimeter. The gun crew was subsequently silenced by Australian sniper

 fire.
Patrolling by the Australians continued in order to prevent the Chinese from harassing their forward positions. Small clashes occurred on the nights of 15/16, 21/22, 22/23 and 23/24 July, suggesting that the Chinese were preparing for a major attack. Aerial reconnaissance subsequently detected a build up of Chinese forces and supplies west of the Samichon River. In response the Australians and US Marines stepped up their defensive preparations, while at the same time rumours from the peace talks started to spread of a ceasefire. Regardless, Chinese harassing artillery and mortar fire intensified, causing a constant stream of casualties among the Australians. Intense Chinese shelling struck Hill 121 and The Hook on the night of 19/20 July, with more than 300 rounds wounding four members of C Company, 2 RAR and further damaging the defences. That night the US Marines were driven off the Berlin and East Berlin features on the left flank, further exposing The Hook, which became a salient

. Yet on 21 July an expected Chinese assault in the US 5th Marine Regiment sector failed to occur, while sightings of Chinese troops across the US 1st Marine Division front declined as the fighting entered a lull.

On 22 July B Company, 2 RAR was relieved on The Hook by D Company, and subsequently moved into reserve. The following day, with the ceasefire believed to be imminent, Wilton limited patrols to only those considered essential for the security of his forward positions. Rumours spread quickly among the troops, with the truce expected to be signed on 26 July. However, by 24 July the Chinese shelling had once again grown in intensity, while large bodies of Chinese infantry were increasingly seen on the forward slopes by the Australians. Meanwhile, similar concentrations of Chinese were also reported by the US Marines. With the Chinese eager to gain a last-minute victory over the UN forces and the tactical advantage offered to the side that held The Hook after the truce, simultaneous attacks were soon launched against 2 RAR and the US 7th Marine Regiment on the left flank, in two major actions on the nights of 24/25 and 25/26 July.

First night, 24/25 July 1953

On the evening of 24 July a 50-strong Chinese force probed 2 RAR's forward outposts after dark, attacking C Company on Hill 121 and surrounding a bunker on the left flank, while the US Marines had a similar contact on the left flank. A forward Australian standing patrol from D Company subsequently clashed heavily with the Chinese probe, losing five wounded before directing tank and artillery fire which dispersed their attackers. These attacks had been preceded by heavy artillery and mortar fire, with the Chinese subjecting C and D Companies, 2 RAR and the 2 RAR Mortar Platoon to a heavy bombardment. Waves of Chinese attacked the Australians at 20:50, penetrating between C Company on Hill 121 and the nearest US Marines on Hill 111, before being turned back amidst the driving rain. A further attack followed another barrage at 23:25, but was again repelled and faltered before reaching the wire during fierce fighting with grenades and small-arms, with the assault failing largely due to the weight of defensive artillery fire. More than 2,000 Chinese mortar and artillery rounds fell on the Australian positions during the night. Two Australians were killed and 14 wounded during the night attack which was later estimated to have been made by a Chinese regiment

 of up to 4,000 men. The defenders were soaking wet and exhausted, but had held their positions. Yet despite the weight of the Chinese attack against the Australians their main objective had been Hill 119, another strong point in the American sector 500 metres (546.8 yd) to the south-west of Hill 111, known as Boulder City, held by the US 7th Marine Regiment.

The Chinese engaged the US Marines on Boulder City with preparatory fire from mortars and artillery at 19:30. Ten minutes later Chinese troops were observed massing for an assault north-west of the Berlin feature and were subsequently shelled by the Americans. At 20:30 the Chinese probed the right flank held by the 3rd Battalion, 7th Marines, first striking Hill 111 and then at Boulder City. After infiltrating forward, the Chinese had hid in the paddy field

s immediately in front of the American positions during the barrage, and had then rapidly assaulted as soon as the artillery had lifted. The attack coincided with the ongoing relief in place of the defenders by the US 1st Marine Regiment under the command of Colonel Wallace M. Nelson, and it subsequently succeeded in temporarily penetrating the American positions on Hill 111. Yet the Chinese main effort fell on Boulder City, and two battalions subsequently succeeded in occupying a portion of the American trench line. From these positions the Chinese threatened to cut-off Company G, 3rd Battalion, 1st Marines on Hill 119, repeatedly assaulting the Berlin Gate feature on the company’s left flank and the East Berlin Gate on its right in an effort to exploit their gains. Throughout the fighting the Marines were strongly supported by heavy mortar, artillery and tank fire; however, due to the prevailing weather conditions no spotter aircraft were able to fly during the night which limited the effectiveness of the indirect fire available to them.

In support of the US Marines on Hill 111 at 21:10 Wilton had ordered one company of the 1 DLI to occupy a reserve position on the left of 2 RAR, in the rear of the US 1st Marine Division where they ultimately remained for the rest of the evening. A reserve company from 3 RAR was also embussed in order to be ready to respond to any emergency. The Americans eventually drove off the Chinese probes after their artillery broke up the attack, but not before they were forced to abandon some of their forward positions. However, with the attack likely only a diversionary effort, by 21:20 the bulk of the Chinese had begun to withdraw from Hill 111. Meanwhile, the fighting on Hill 119 continued. A heavy bombardment fell on the American positions at 21:00, followed by a second assault on Hill 119 by two Chinese companies which succeeded in penetrating the US Marine perimeter. Hand-to-hand combat developed across the forward trenches and in the ensuing fighting Company G was reduced to half-strength, while their ammunition began to run low. Under pressure, by midnight the Americans were forced back another 1500 metres (1,640.4 yd) to the reverse slope. 3 RAR was subsequently left exposed, with the forward Chinese elements moving to within 1200 metres (1,312.3 yd) of the battalion's A Echelon area. Almost surrounded, the position was at risk of becoming untenable. At 00:15 Company I, 3rd Battalion, 1st Marines was ordered to reinforce Boulder City; however, they also lost heavily after the Chinese intercepted a coded message and adjusted mortar and artillery fire onto the Marines as they approached the rear of Hill 119. In response the 11th Marine Artillery Regiment launched an intense counter-battery

The Chinese also launched a number of assaults in the central sector against the US 5th Marine Regiment, commanded by Colonel Harvey C. Tschirgi. Successively striking outposts on the regimental right flank from 21:15, a reinforced Chinese company from the 408th Regiment then concentrated against outpost Esther, held by Marines from Company H. Amid heavy fighting both sides were reinforced. By early morning the Chinese had seized parts of the forward American trench-line and moved to isolate the position with indirect fire and patrols which penetrated between the outpost and the main defensive position to the rear; however, with the Marines still controlling the rear trenches they successfully reorganised their defence and succeeded in checking the Chinese assault. Defending strongly, the Marines used flamethrower

 tanks and artillery fire and following several hours of fighting the Chinese attack was finally broken up by indirect fire. An entire Chinese battalion had been committed piecemeal to the attack, yet by 06:40 the following day the US Marines reported Esther secure. More than 4,000 artillery and mortar rounds had fallen on the outpost during the night; Marine casualties included 12 killed and 35 wounded, while Chinese loses included 85 dead which were counted around the position, 110 more believed killed and an estimated 250 wounded.

In the US 7th Marine Regiment's sector, heavy shelling, small arms fire and hand-to-hand fighting continued around Boulder City into the early morning on 25 July. Chinese infantry had succeeded in breaking through and occupying a large part of the trench-line on the forward slopes, and for a while even temporarily occupied the crest. At 01:30 Companies G and I, 3rd Battalion, 1st Marines launched a rapid counter-attack and by 03:30 the American perimeter had been re-established, and was subsequently reinforced. By 05:30 Hill 119 was secured by the US Marines, although scattered groups of Chinese remained on the forward slopes, while others attempted to reinforce the left flank. Sporadic fighting and heavy shelling also continued on Hill 111 in the early morning hours, and at 04:00 another fight developed; however, by 05:30 the position was also controlled by the Americans. Four M46 Patton tanks on Boulder City dispersed the Chinese concentrations with high explosive and machine-gun fire, while Marine infantry assault teams with flamethrowers and 3.5-inch rocket launchers subsequently cleared the remaining Chinese from their former bunkers. In total, more the 3,000 Chinese troops had assaulted the front held by the US 1st Marine Division during the night of 24/25 July.

Throughout the night the US 11th Marine Artillery Regiment had been heavily engaged, with the regiment and the 10 battalions under its operational control in the US 1st Marine Division sector firing a total of 23,725 rounds, including those from batteries of the US 25th Division Artillery, the US I Corps Artillery and the 1st Commonwealth Divisional Artillery. The weight of indirect fire available to the defenders had been significant and the whole of the 1st Commonwealth Divisional Artillery had also been engaged during the fighting, firing in support of both the Australians on Hill 121 and the US Marines on their left flank, defending Hill 111 and Boulder City.

s proved of considerable assistance. A liaison officer from 16 RNZA was sent subsequently over to the US Marine artillery regiment during the night to establish communication. More than 13,000 rounds were fired by the British and New Zealand gunners that night, with the close defensive fire having a devastating effect on the assaulting Chinese infantry. The artillery had also effectively halted the Chinese assault against Hill 121, resulting in a fair degree of frustration among the Australian infantry, some of whom later expressed disappointment at being prevented from getting to grips with the Chinese by the accurate New Zealand artillery fire.

Before the battle, a section from the 2 RAR Medium Machine Gun Platoon had been stationed within the American perimeter near Hill 111 to provide covering fire across the area between the positions occupied by the US Marines and the Australians. Commanded by Sergeant Brian Cooper they soon found themselves in the thick of the fighting, firing their Vickers machine-guns in support of the Australian positions and to defend themselves from the weight of the Chinese main attack which fell on the Marines. Three men were wounded during the night but the machine-gunners continued to fire in support, while the remainder of the section repelled a number of Chinese assaults from the left. Ultimately the Chinese were unable to dislodge them, with the Australians calling-in artillery on to their own positions during repeated Chinese attempts to over-run them as the US Marines withdrew past their position, leaving them isolated. When dawn came dozens of Chinese bodies were found strewn in front of the Australian machine-gunners. As the US Marines worked to clear the Chinese stragglers from their position the Australians had endeavoured to coax a Chinese soldier from a bunker, yet when he resisted they were forced to kill him with a grenade.

 for his leadership, with the stubborn defence of the Australians contributing to the break-up of the Chinese attack which at one stage had threatened to over-run the Marine position. Large groups of Chinese remained though, occupying a number bunkers and trenches, and they were not finally dislodged by the Marines until the following afternoon.

Second night, 25/26 July 1953

At 08:20 on the morning of 25 July the Chinese again assaulted the US Marines on Hill 119 in company strength but were soon halted by American artillery and mortar fire which inflicted heavy losses; however, skirmishing continued for the remainder of the day. While no major assaults against Hill 111 occurred, a heavy barrage by the Chinese targeted the position at 11:00. F9F Panthers provided air support to the Marines throughout the day, while American tanks continued to engage Chinese targets in support of the defenders on Hill 111 and Boulder City. Finally, at 13:35 the last of the Chinese infantry were forced off the forward slopes of Boulder City by the US Marines. Chinese casualties were estimated by the Americans to have included another 75 killed and 425 wounded. The Chinese continued to heavily shell the American positions, and by late afternoon 13,500 mortar and artillery rounds had fallen on the sector held by US 7th Marine Regiment. The Americans fired a large number of counter-battery missions in response, firing 36,794 rounds. The ongoing relief of the US 7th Marine Regiment continued throughout the day. Meanwhile, the Australian positions on The Hook were also heavily shelled throughout the day, forcing many of the defenders underground into the network of tunnels then being extended by a team of New Zealand sapper

Realising that they had only faced a series of probes the previous night, rather than a major attack, and as these actions may have been in preparation for a heavier attack, a vigorous defence was subsequently prepared by the Australians with the reserve companies moved into blocking positions to strengthen the forward defences. The defenders endured steady shelling and harassing fire, while after dark The Hook was probed again, this time by a group of about 20 Chinese. The force was subsequently engaged by an Australian standing patrol from D Company at 21:00 and forced to withdraw, leaving behind one dead at a cost of one Australian killed and one wounded. However at 21:20 the Chinese fire had become more intense, and a heavy blow was launched by the Chinese against the Marines on Hill 119 shortly after. Beginning at 21:30, elements of the 1st and 7th Marines were attacked by two Chinese companies. A heavy concentration by the entire US I Corps artillery was fired in response, and the Chinese were forced to withdraw. At 23:00 the Chinese shelling intensified to thirty-rounds per minute, and was followed fifteen minutes later by another determined charge by the Chinese infantry against the US Marines on the left flank on Hill 111 and Boulder City during a furious attack. The Australian positions were not directly attacked during the night, although C Company engaged the Chinese in no man's land sporadically at long range in support of the Americans. As on the previous night, 3 RAR was not attacked. In total more than 4,200 mortar and artillery rounds were fired by the Chinese at 2 RAR during the night, and three Australians were killed and nine wounded.
In contrast the US Marines were more heavily engaged, with the fighting occurring at close quarters for more than an hour before they repelled their attackers and counter-attacked. An Australian bunker between the US Marines on Hill 111 and C Company, 2 RAR on Hill 121 was also the scene of heavy fighting, after the Chinese penetrated the undefended space between the two positions. Manned by just six Australians under the command of Lance Corporal Kenneth Crockford, the position was attacked by the Chinese simultaneously from several sides following a determined charge at 23:40. During bitter hand-to-hand fighting in the trenches around the bunker the under-strength Australian section ejected the Chinese and prevented them from advancing any further. They then directed artillery fire onto their position to break up subsequent attacks. Further Chinese probes were launched against Hills 111 and 119 in the early hours of 26 July, and they succeeded in temporarily seizing parts of the American trench line. Between 01:30 and 03:00 heavy fighting continued before the Chinese were driven from the position by the US Marines. Meanwhile, Wilton ordered D Company, 3 RAR to move across to occupy the position behind B Company, 2 RAR to support the US Marines if required, while at 02:18 he placed A Company, 1 DLI on five minutes notice to move to another blocking position. American casualties were 19 killed and 125 wounded, while Chinese losses included 30 men countered dead, and another 84 estimated to have been killed and 310 wounded.

The 2 RAR Machine Gun Platoon on Hill 111 again found itself heavily engaged, suffering five badly wounded. The Chinese had managed to establish an artillery forward observer

 on Hill 111 and US Marine casualties were particularly heavy as a result. Eight critically injured Americans were subsequently evacuated through 2 RAR for urgent medical treatment. Small-arms fire continued to be exchanged between the US Marines and the Chinese for the next two hours, only subsiding by 03:00, with the Marines finally driving out the Chinese. D Company, 3 RAR was subsequently released and it returned to battalion's main defensive position. The Australian outpost section also succeeded in holding through the night and the following morning they found 35 Chinese dead around their positions. During the fighting Crockford had repeatedly exposed himself to Chinese fire, and had even run across no man's land to provide situation reports to the US Marine command post on Hill 111. He was later awarded the Military Medal for his actions. By dawn the only activity in front of The Hook were Chinese stretcher bearers collecting their wounded, which were subsequently allowed to do so unmolested by the Australians. In the US 1st Marine Division's sector the fighting had also ceased, while small groups of Chinese moved to reinforce their positions and were engaged with rifle and machine-gun fire.
As with the first night, indirect fire had again played a crucial role in the defence, with the New Zealand gunners firing another 5,700 rounds (out of a divisional total of 9,500 rounds) in support of the Australians and the US Marines. Dug-in to the east, 16 RNZA had been forced to fire with minimum crest clearance over the Australian lines in order to bring effective fire to bear on the assaulting Chinese from their 25-pounders.

s to break up the Chinese assaults, causing heavy casualties. Despite the risk of causing casualties among their own soldiers no serious casualties were incurred by the Australians, although one suffered a broken shoulder after a brass nose cone from a faulty time-of-flight fused shell exploded over his position. High explosive was also provided by C Company's 60 mm mortar which operated against the Chinese in no man's land despite being exposed and unprotected from fire, while the mortars also provided battlefield illumination which had allowed the Australian riflemen and machine-gunners to bring accurate fire to bear on the Chinese crossing 2 RAR's front to attack Hills 111 and 121. The Chinese had suffered heavily during the fighting, with over 300 dead counted in front of Hill 111 alone. Throughout the following day the Australians observed a steady stream of Chinese casualties evacuating Hill 111 and crossing the paddy fields on the left flank. Later, a group of 20 armed Chinese had also attempted to withdraw but were engaged by the 2 RAR Anti-Tank Platoon, resulting in at least six casualties. In the US 1st Marine Division section, Chinese shelling continued sporadically, while at 13:30 the US 1st Marine Regiment assumed operational control of the right sector.

Aftermath

The battle illustrated the power of concentrated artillery fire and the wastefulness of massed attacks by infantry against modern firepower. Hundreds of Chinese dead lay around in front of the UN positions, with the valley floor "almost covered with dead Chinese". Wilton later recounted that on "the approaches to 2 RAR the bodies literally carpeted the ground sometimes two deep". Later, it was estimated that Chinese casualties numbered between 2,000 and 3,000 killed, with the majority of them inflicted by the New Zealand gunners. The fighting between 24–26 July had cost the Australians five killed and 24 wounded, while during the previous two weeks on The Hook 2 RAR had lost a total of 17 men killed and 31 wounded.

, while a member of his tactical party, Gunner Arthur Bolton, was later Mentioned in Despatches. In total over the three nights more than 23,000 rounds were fired by the Commonwealth Divisional Artillery.
During the final month of the war heavy fighting had occurred across the central and eastern fronts. Yet in the Commonwealth sector itself the only Chinese attacks had been made against 2 RAR holding The Hook on the nights of 24–25 and 25–26 July. The action was part of a larger attack against the US 1st Marine Division, with only diversionary assaults mounted against the Australians. 1st Commonwealth Division intelligence staff believed that the Chinese had been attempting to make a breakthrough to the Imjin River along the divisional boundary in order to turn the US 1st Marine Division's flank, yet with well-coordinated indirect fires from the divisional artillery and support from the British tanks, 2 RAR had been able to successfully thwart both assaults. Meanwhile, the US Marines had endured the brunt of a divisional

-size attack, repelling the Chinese onslaught for the loss of 43 killed and 316 wounded over the two nights; total Marine casualties for July included 181 killed and 1,430 wounded.American estimates of Chinese losses during fighting in the US 1st Marine Division sector in July included 405 counted dead, 761 estimated killed, 1,988 estimated wounded and 1 captured. See . Indeed, with the Chinese determined to gain local territorial advantage prior to signing the ceasefire, the United Nations Command had suffered 65,000 casualties during the final three months of the war, while the Chinese lost at least 135,000 more.

On 26 July Wilton had ordered Lieutenant Colonel Peter Jeffreys to prepare a counter-attack by 1 DLI to recover some of the ground lost to the Chinese the night before, however after the preparatory fire failed to clear the Chinese from the objective the assault was cancelled. The Chinese subsequently made another attempt against the US Marines on Hill 119 on the night of 26/27 July; however, it lacked the weight of those of the previous nights and was easily repelled.

 had advanced on the wire at Hill 119, defended by Company E, 2nd Battalion, 1st Marines. Just after midnight another Chinese platoon-sized assault was also halted by the Marines. At 00:45 a Chinese platoon probed the US Marines on Hill 111, yet after an hour and twenty minutes it was also checked. Meanwhile, despite the clashes nearby on Hill 111 the Australians suffered no more casualties. The Armistice Agreement was subsequently signed at 10:00 on 27 July. Sporadic fighting continued, and the New Zealand gunners fired a number of counter-battery tasks, engaging several Chinese guns. The Commonwealth Divisional Artillery fired 1,300 rounds during the day; however, by evening the front was largely silent. In the last four hours of the war the Chinese fired 44,000 artillery rounds into the US Eighth Army positions, although none against the 1st Commonwealth Division. There were no further attacks and the ceasefire came into effect at 22:00 the same day. The following day some soldiers from both sides moved forward into no man's land to exchange greetings, although relatively few Australians did so and the Marines were under orders not to fraternise or communicate with the Chinese.
With the war over both sides were required to withdraw 2 kilometres (1.2 mi) within 72 hours to create a 4 kilometres (2.5 mi) demilitarised zone, and preparations began to hastily evacuate the forward positions. During August and September sappers from the 1st Commonwealth Division were subsequently engaged clearing minefields and demolishing many of their former defended localities and field defences, while new battle positions were established to the rear. A similar process occurred across the entire front. Meanwhile, under the terms of the agreement all prisoners who wished to be repatriated were to be returned, and 12,773 UN and 75,000 communist prisoners were subsequently exchanged during this period, including 21 Australians and one New Zealander.This figure does not include the sick and wounded repatriated in April 1953 as part of Operation Little Switch, including five sick and wounded Australians. See . The period that followed proved uneventful, yet the UN forces were required to maintain combat readiness and the ability to react quickly in case the North Koreans violated the ceasefire. In April 1954, 2 RAR returned to Australia and was replaced by 1 RAR which remained in South Korea until March 1956. 3 RAR finally returned to Australia in September 1954 after four years of continuous service in Korea and five years before that in Japan. British Commonwealth forces remained in Korea until they were finally withdrawn in August 1957.
