We meet some of the extraordinary last survivors of the generation who fought or lived through World War II. Now in their nineties and hundreds - the oldest is 110 - they come from both rich and poor backgrounds. We find out how these men and women of Britain's Greatest Generation were shaped by their childhood experiences.

For no generation of Britons in modern history has war been such a defining feature than in the lives of those born just before, during, or soon after the First World War. The euphoria of victory in 1918 had imbued many with an overwhelming sense of patriotism and pride in Britain that would remain deep-rooted for years to come.

But national unity was seriously tested in the 1920s and 30s, as Britain became a country riven with class conflict and inequality. As unemployment soared, there was widespread civil unrest.

Despite these upheavals, those growing up in the interwar years remember much that was positive about life in Britain at the time. Their stories reveal that personal qualities of courage, initiative, obedience and fairness - seeded by parents of all classes - were highly valued. Most strikingly, they shared a delight in exercising freedom and independence - attributes that would come in useful as another world war approached.

When war broke out in September 1939, the men and women of this generation had just come of age and were ready to risk their lives for their country. But the evacuation of the British Army from the beaches of Dunkirk was a wake-up call for those who expected a swift victory. By the summer of 1940, Britain stood alone, with the Nazis massed across the English Channel. The Battle of Britain was about to begin - and the men and women of Britain's Greatest Generation were ready to fight it. Show less
