In August 1945 the Japanese in Malaya finally surrendered. The Malayan People's Anti-Japanese Army, who were largely Communist, emerged from the jungle to make claim on the promises given them by the British and Malayan authorities. They were to be disappointed. The pre-war ban on the Communist Party in Malaya continued and the promise of land and money in recognition of their brave service failed to be honoured. After three years of frustration they returned to the jungle now calling themselves the Malayan Races Liberation Army. They started to blow up bridges, ambush roads and abduct local businessmen, many of whom were murdered. In 1948, a state of emergency was declared and British and Commonwealth Troops entered the jungle to kill or capture their former allies. This proved no easy task, for their enemy had been well trained during the war by British instructors. The emergency or 'The Undeclared War' lasted until 1960, when the remnants of the terrorists finally accepted an amnesty. The novel 'Jungle Haven' is the sequel to that of 'Strange Alliance'.
The story restarts in July 1952 as the book's two main characters, Royal Marines Sgt Major Jim Muir and Sgt Peter Blake, are coming to the end of their unit's two-year stint fighting the terrorists. They have just completed their last patrol and are about to prepare for the move to Singapore then onward to Malta in the troopship Dilwara.
