Evacuation

Evacuation is when someone needs to leave an area because there is danger in the area they are currently. Thousands of children during the war were evacuated to rural areas because of the German bombing campaign, The Blitz. The children who were evacuated were officially known as evacuees. When they travelled into the countryside areas, like Devon, Cornwall, Wales and many others, they lived with people known as host families. Although it wasn't a particularly fun experience most of the children were sent away adapted to country life very well.
But why were they evacuated?
They were evacuated because it was simply too dangerous to live in urban areas such as London or Birmingham. The Germans decided that they were going to bomb urban areas because there was a greater population and that means they would secure more English deaths. Occasionally an air raid siren would go off (more information about that on 'Air Raid Shelters' so the children were forced to carry around a rather large gas mask.
Most evacuees and their parents kept in touch by sending letters or, if they were lucky, by radio. Evacuation was voluntary and only some children went. Although I say some I mean 3.5 million. The evacuation scheme launched by the English government was called 'Project Pied Piper'. I hope the two videos help you learn more about evacuation.
