Sunset of Arms: Fitton v Pusey: Part 1

A military historian has been accused of libel by a British Army Major following the publication of a book on the British Army's involvement in the Korean War. The author claims that the Major abandoned his post and left his company of soldiers to be massacred by the North Koreans. The Major insists that he was the last man standing in the conflict and escaped to safety only after the rest of his company was wiped out. Was the Major a hero, or a coward?
