In 1933 Adolf Hitler rose to power as the leader of the NAZI party in Germany. They were not nice people and they wanted to take over the world. In 1939 they attacked their neighbouring country Poland. Britain was worried that Germany would attack them so asked Germany to leave Poland. The Nazis refused and the war started on the 1st of September,1939.
AIR RAID PRECAUTIONS
The Nazis wanted to take over Britain. They knew if they could invade Britain, they would be undefeatable. Because Britain was an island, they could not invade by land, like they invaded Poland, and if they invaded by sea, it would be easy for the British to fight back. So they decided to attack by the air, using planed to drop bombs on British cities. These attacks were called Air raids.
