On 1 September 1939, two days before the declaration of war, Operation Pied Piper began. Over four days, 1.5 million people — primarily children, but also pregnant women, mothers with infants, and disabled people — were evacuated from cities considered vulnerable to bombing.
By the end of the war, a total of 3.5 million people had been moved in several waves of evacuation, making it the largest mass movement of people in British history.
Children assembled at schools with gas masks, a change of clothes, and a packed lunch. Labels with their names were tied to their coats. They marched to railway stations in crocodile lines, often not knowing where they were going. Parents waved goodbye, many not knowing when — or if — they would see their children again.
Reception varied enormously. Some evacuees found loving foster families who gave them experiences they could never have had in the city — fresh food, countryside walks, proper schooling. Others suffered neglect, cruelty, or exploitation. The scheme exposed the class divisions in British society, as middle-class rural families were confronted with the poverty and health problems of inner-city children.
The evacuation had profound social consequences. The exposure of urban poverty to rural Britain is credited with helping build public support for the welfare state reforms that followed the war, including the National Health Service. For the children themselves, the experience was formative — some recall it with fondness, others with lasting trauma.
