This is the story of how ordinary Britons from every class and background turned years of struggle and heartache into a triumph of quiet courage and invincible good humour.
From the terrors of the Blitz and the camaraderie of the air raid shelter, to the sudden arrival of hordes of glamorous American servicemen.
This programme is about the heartbreak of sons and husbands parted from their families and, ultimately, of the joy of being re-united.
It documents the long years before the Allies made their final push for victory, and shows how the citizens of a beleaguered nation sang, danced and laughed their worries away.
How the War was Won - The Victory Years 1944-1945 is also available in the Britain at War eight-disc box set.
