PoW's memories of 'forgotten' Korea war

A service of thanksgiving will take place at Westminster Abbey on Thursday to commemorate those who fought in the Korean War over 60 years ago.
British and Commonwealth troops served on the Korean Peninsula as part of a United Nations coalition force after North Korean troops invaded South Korea in June 1950.
By the time an armistice was signed on 27 July 1953, over 1,000 British servicemen had lost their lives and around another 1,000 had been taken prisoner by the North Korean forces and their Chinese allies.
Estimates for the total number killed on both sides range from more than 500,000 to almost 1 million.
Major David Sharp was an intelligence sergeant in the Royal Northumberland Fusiliers during the war, and was captured behind enemy lines.
He spoke to BBC News about what he endured during his time as a prisoner of war and his memories of the conflict.
