On 11 April 1951, President Truman relieved the General MacArthur as Supreme Commander in Korea. There were several reasons for the dismissal. MacArthur crossed the 38th Parallel in the mistaken belief that the Chinese would not enter the war, leading to major allied losses. He believed that whether to use nuclear weapons should be his decision, not the President's.
Giáp launched yet another attack, the Battle of the Day River, on May 29 with the 304th Division at Phủ Lý, the 308th Division at Ninh Bình, and the main attack delivered by the 320th Division at Phat Diem south of Hanoi.

During her 21st birthday party at Balmoral in August 1951, the press was disappointed to only photograph Margaret with Townsend, always in the background of pictures of royal appearances, and to her parents, a safe companion as Elizabeth's duties increased.

The Battle of the Punchbowl, was one of the last battles of the movement phase of the Korean War. Following the breakdown of armistice negotiations in August 1951, the United Nations Command (UN) decided to launch a limited offensive in the late summer/early autumn to shorten and straighten sections of their lines, acquire better defensive terrain, and deny the enemy key vantage points from which they could observe and target UN positions. The Battle of Bloody Ridge took place west of the Punchbowl from August–September 1951 and this was followed by the Battle of Heartbreak Ridge northwest of the Punchbowl from September–October 1951. At the end of the UN offensive in October 1951, UN forces controlled the line of hills north of the Punchbowl.
Five days later, on September 3, he flew armed reconnaissance over the primary transportation and storage facilities south of the village of Majon-ni, west of Wonsan. An initial report to the commanding officer of Essex said that while attacking a target, Armstrong's F9F Panther was hit by anti-aircraft fire. The report indicated he was trying to regain control and collided with a pole, which sliced off 2 feet (1 m) of the Panther's right wing. Further perversions of the story by different authors added that he was only 20 feet (6 m) from the ground and that 3 feet (1 m) of his wing was sheared off.
The Battle of Bloody Ridge was a ground combat battle that took place during the Korean War from 18 August to 5 September 1951. By the summer of 1951, the Korean War had reached a stalemate as peace negotiations began at Kaesong. The opposing armies faced each other across a line which ran from east to west, through the middle of the Korean peninsula, located in hills a few miles north of the 38th Parallel in the central Korean mountain range. United Nation and the North Korean Korean People's Army (KPA) and Chinese People's Volunteer Army (PVA) forces jockeyed for position along this line, clashing in several relatively small but intense and bloody battles. Bloody Ridge began as an attempt by UN forces to seize a ridge of hills which they believed were being used as observation posts to call in artillery fire on a UN supply road.

The Battle of Heartbreak Ridge , also known as the Battle of Wendengli , was a month-long battle in the Korean War which took place between 13 September and 15 October 1951. After withdrawing from Bloody Ridge, the Korean People's Army (KPA) set up new positions just 1,500 yards (1,400 m) away on a 7-mile (11 km) long hill mass. If anything, the defenses were even more formidable here than on Bloody Ridge. The Battle of Heartbreak Ridge was one of several major engagements in the hills of North Korea a few miles north of the 38th Parallel (the pre-war boundary between North and South Korea), near Chorwon. For the Chinese, this battle is often confused with the Battle of Triangle Hill, which occurred a year later.
The Conservatives won the general election in October 1951 with an overall majority of 17 seats and Churchill again became Prime Minister, remaining in office until his resignation on 5 April 1955. Eden, his eventual successor, was restored to Foreign Affairs, the portfolio with which Churchill was preoccupied throughout his tenure. Future Prime Minister Harold Macmillan was appointed Minister of Housing and Local Government with a manifesto commitment to build 300,000 new houses per annum, Churchill's only real domestic concern. He achieved the target and, in October 1954, was promoted to Minister of Defence.
