Part 6 of 8. Even as Australia prospered in the years following the Second World War, fears for the future were beginning to take hold. The extraordinary power of the atomic bombs that ended the war had raised the terrifying possibility that any future global conflict might threaten not only individual lives, but perhaps the existence of life itself. Within a few short years, a new form of war began to cast its shadow over post-war prosperity in the West; a "Cold War" waged against an enemy armed with both nuclear weapons and an oppressive political ideology - Communism. Despite concerns over the Cold War escalating into all-out global conflict, the Australians who volunteered to fight Communist expansion into South Korea did not find themselves engaged in any new form of warfare. Rather, the gruelling and protracted campaigns in which they engaged were strongly reminiscent of those fought by their grandfathers on the Western Front. Part Six of Australians at War, "The Forgotten War", looks at the remarkable courage, endurance and tenacity of the Australians who served in the Korean War and the subsequent insurgencies in Malaya and Indonesia. Despite noisy protests by a small group of Communists in their own country, all believed it was their duty to uphold the traditions and values of the forebears and all were prepared to make the ultimate sacrifice to do so. For many this was the essence of what it meant to be Australian. After the bloody and exhausting Battle of Kapyong, a critical turning point in the Korean War, one World War II veteran who subsequently volunteered to serve in Korea remarked: "At last I feel like an Anzac and I imagine there were 600 others like me." Most Australians have little knowledge of these "forgotten wars". None received the widespread coverage of those that preceded them. However, the stories of those who served in them, like Serge ant Jack Galloway who fought at the Battle of Kapyong, and Captain Phil Greville who endured internment and torture at the hands of the enemy, remind us that the fierce struggle they waged against Communist forces played a vital role in preventing an even more devastating war like that feared by so many Australians.
