[9] In early April, Carne and his battalion were spread over a 9-mile (14 km) front along the Imjin River guarding a ford which was part of the main route to the city of Seoul.

[10] In what became known as the Battle of the Imjin River, Carne's Glosters and the rest of the British brigade were met by an onslaught of over 27,000 Chinese troops attacking in massed waves.

On two separate occasions, armed with rifle and grenades, he personally led assault parties which drove back the enemy and saved important situations.

Carne requested permission to attempt a breakout and ordered his men to split into small groups and make as best they could back to the British lines.

[16] According to documents held at the National Archives in Kew and not made public until 2006, when Carne was released in September 1953 he told Sir Esler Dening, the British ambassador in Tokyo, "an extraordinary story" of brainwashing.

The note, which was sent straight to Sir Winston Churchill, in his second term as prime minister, went on: "In March of this year, (i.e. about the time when the communists displayed a new interest in concluding an armistice) various thoughts were put into his mind, and he remains convinced that he was meant to retain these and pass them on to Her Majesty's Government."

[18] In 1954 it was announced that Warwick Productions wanted to make a film The Glorious Glosters starring Alan Ladd as Carne based on a script by Max Trell.
