In the 1940s the Anderson shelter was 3d (1.5p) to buy, it could then be put in the back garden. This was then covered with soil and grass. You also had to have sandbags for around the outside. People also went down to the railway underground were you took your bedding gasmask food and drinks.
Some people got the shelter for free. If there earning was less then £250. A year. In 1940s nearly a quarter of the population had one. It consisted of curved steel which was bolted together and had to be dug into the earth. The shelters were small rather more suitable for putting bikes in. they were also liable to flood. But the main drawback was that many people in the cities had no garden. So that when people went down to the underground. There they had concerts from the ENSA groups. But even then people got killed. 1stLondon became one of Hitler targets. Then it got to be the other big city’s ie Liverpool. Coventry, Leeds. Manchester Were raids were to be every night. In London 1 million 4 hundred thousand people had been made homeless. Also the other big cities were to become the same.
