He and his lifelong friend, David Gilbert-Smith, led two platoons of the Duke of Wellington's Regiment during the Battle of the Hook in Korea, recovering positions overrun by the Chinese offensive. Campbell-Lamerton had already escaped a life-threatening injury at school when, aged 15, he was struck on the chest by a javelin; he courted death again on foot patrol in Korea when he trod on a mine. Hearing the faint click, he remained still while the corporal with him, who fortunately had worked in bomb disposal during the Second World War, rendered it safe. Three years later, serving in Cyprus during the EOKA campaign, he fell 60 ft from a helicopter in full combat gear, sustaining severe back, hip and leg injuries. That he recovered to play international sport is a tribute to his perseverance as well as his ability; He played rugby for his regiment, the Army and Combined Services, and club rugby with Halifax, Blackheath Rugby Club and London Scottish RFC. He eventually rose to the rank of Colonel before leaving the army.
Rugby
His debut for Scotland came against France at Colombes on 7 January 1961. He went on to gain 23 Scotland caps as he appeared in the next five seasons, twice as captain in 1965. He was picked for the 1962 British Lions tour to South Africa, playing all four internationals at number eight. But when the Lions team was selected for the 1966 tour, he was 32, no longer captain of his country and the leadership was expected go toAlun Pask, the outstanding Welsh No. 8. Massie says that "You would have had no doubt that he could push in the scrum, and with him and Frans Ten Bos together it achieved a solidity and power that had long been lacking." Campbell-Lamerton was 6 ft 5 inches and 17 stone. However, he also says that Lamerton was not a good national captain: "He was perhaps over-conscientious and a worrier, and hardly spoke the same language as many of the team; it affected his play." In terms of sheer entertainment value, Massie says, "I doubt if any other Scottish lock forward has given so much fun, not even Alastair McHarg." Richard Bath writes of him that he was: Allan Massie provides a more colourful description of him:
Though the Lions beat in successive internationals, the New Zealand section of the tour was marred by ill feeling. After the game with Canterbury, the Lions captain for the day, Jim Telfer, said at the after match function: "I would not describe today's game as dirty because all our games in New Zealand have been dirty." Understandably this caused a furore but it was the backdrop against which Campbell-Lamerton had to keep his players united. Campbell-Lamerton, would not have been out of place in the modern game: he was a big man, at 6 feet 5 inches, weighing more than 17 stone, yet athletic enough to play No. 8 as well as his accustomed position in the second row. But the qualities which served him best on the difficult tour of New Zealand as captain of the 1966 Lions were his commitment and willingness which did so much to sustain a struggling tour party. At one stage the manager, Des O'Brien left the party for a reconnaissance mission to Fiji, and the coach, John Robins, was in hospital with damaged ankle ligaments, leaving Campbell-Lamerton with far greater responsibilities than any modern equivalent would face. Yet in a squad which he had not been expected to captain, his players still speak warmly of the example he set after a tour in which the Lions lost all four internationals against the All Blacks. The recurrence of an ankle injury which caused his withdrawal from the second game against New Zealand, did not help and he also missed the final international. "Mike was a decent man and much-maligned", Brian Price, his second-row partner in three of the tour internationals, said. "We knew how hard he was working and it was because we respected his efforts, we stuck together." After the tour he retired from playing rugby. In 1972 he was appointed to coach the British Combined services team. In his military career, he rose to the rank of colonel, led him to the command of a battalion in Northern Ireland, thence to the Royal Military Academy, Sandhurst, where he was commander of Old College and Victory College.
Post-military
He left the Army in 1985 and became bursar at Balliol College, Oxford, later being elected an Emeritus Fellow of the college. He also took a close interest in the fortunes of the university rugby club, whose president he eventually became. He was elected a Knight of Malta, the organisation which raises funds for Catholic charities. In 2001 prostate cancer was diagnosed, an illness he endured with great fortitude until his death on 17 March 2005, aged 71.
Family
In 1956 Campbell-Lamerton met and married Marie-Christine while stationed in Gibraltar. They had three sons: Jeremy, who also played lock for Scotland five times in the 1986-7 season, Michael Patrick, Ian Anthony and a daughter Clare Josephine Margaret.

Campbell-Lamerton received a MBE in 1974, then an OBE in 1979.
