In November 1938, Prime Minister Neville Chamberlain placed Sir John Anderson in charge of Air Raid Precautions. Sir John was a scientist turned politician who was responsible for setting up the Civil Defence Research Committee in May 1939 to address the prevailing ignorance about the physical and psychological consequences of explosions. He commissioned the engineer, William Patterson, to design a small and cheap shelter that could be erected in people's gardens. The first 'Anderson' shelter was erected in a garden in Islington, London on 25 February 1939 and, between then and the outbreak of the war in September, around 1.5 million shelters were distributed to people living in areas expected to be bombed by the Luftwaffe. During the war a further 2.1 million were erected.
Anderson shelters were issued free to all householders who earned less than £250 a year, and those with a higher income were charged £7. Made from six curved sheets bolted together at the top, with steel plates at either end, and measuring 1.95m by 1.35m, the shelter could accommodate six people. The shelters were half buried in the ground with earth heaped on top.
I understand - though I haven't seen the detail - that the shelters were issued free of charge to all householders later in the war. Before that, householders who had been issued with free shelters (and who didn't have big families) sometimes allowed their slightly better off neighbours to share them.
The shelters were very strong - especially against a compressive force such as from a nearby bomb - because of their corrugation. Click here for further information about their strength and durability.
Anderson shelters were effective only if half buried in the ground and covered in a thick layer of earth. They were therefore inherently cold, dark and damp. In low-lying areas the shelters tended to flood, and sleeping was difficult as the shelters did not keep out the sound of the bombings. If there was a toilet at all, it took the form of a bucket in the corner.
Therefore, although some families slept in them every night, most people were reluctant to use them except after the air raid sirens had sounded - and often not even then. People were recommended to take important documents with them, such as birth and marriage certificates and Post Office Savings books. But it was difficult to remember what to do when you had just woken from a deep sleep, it was totally dark and the sirens were wailing.
Here is an aerial view of a terrace in London's Nine Elms towards the end of the war. Two shelters can be seen towards the bottom of the picture.
Another problem was that the majority of people living in industrial areas did not have gardens where they could erect their shelters. It is therefore not surprising that a November 1940 survey discovered that only 27% of Londoners used Anderson shelters, 9% slept in public shelters and 4% used underground railway stations. The rest of those interviewed were either on duty at night or slept in their own homes. The latter group felt that, if they were going to die, they would rather die in comfort.
Many families tried to brighten their shelters in various ways, and they often grew flowers and vegetables on the roof. One person wrote that "There is more danger of being hit by a vegetable marrow falling off the roof ... than of being hit by a bomb!'
But others were more nervous - and with good cause. After a parachute bomb hit a nearby school, one set of Bournemouth parents - the Heaths - decided to erect their shelter indoors, and cover it with sandbags. The lovely photo opposite was kindly sent to me by David Heath (top right) together with his brother and sister, all looking decidedly not at all scared!
In best "Keep Calm and Carry On!" mode, a 1940 edition of Good Housekeeping magazine carried a recipe and decorating instructions for this Christmas cake.
The corrugated iron roofs of most of the shelters were collected by the authorities at the end of the war. Others were sold to the householders for £1 each. These were often dug up and re-erected above ground, fitted with proper wooden doors and used as workshops or garden sheds. Click here for more information and some photos.
Those shelters which are still in their original position, and known to the author of this website, are listed in the 'Photos & Visits' box on the home page.
There are numerous wartime photos of Anderson shelters on the web, accessible, for instance, by using Google/Images.
"Despite Hitler's orders that he alone was to decide on terror bombing, 100 planes of the Luftwaffe, acting, it seems, under a loosely worded directive from Göring ... had attacked London's East End on the night of 24 August. As retaliation, the RAF carried out the first British bombing raids on Berlin the following night. Hitler regarded the bombing of Berlin as a disgrace. ... his reaction was to threaten massive retaliation. ... From 7 September the nightly bombing of London began." - Ian Kershaw 'Hitler' p570.
German strategic bombing of the UK between 1939 and 1945 killed around 50,000 people. London, Liverpool and Birmingham were the most bombed cities, in that order. Here, to the left, is a 1945 view of the area around St Paul's Cathedral in London. Click on the image to see a much larger version.
Similar attacks on German cities killed around 500,000 - ten times as many. Many of the later attacks were carried out by Britain's Bomber Command which itself lost 50,000 crew in the conflict. The single atomic bomb dropped on Hiroshima killed between 90,000 and 140,000 Japanese.
The V2 rocket bomb killed around 2,700 in England and destroyed around 20,000 houses, damaging another 580,000 through their enormous shock-waves.
In total, during the war, around 220,000 UK dwellings were destroyed or so badly damaged that they had to be demolished. At least 3.5 million more suffered some form of damage. Around 30% of the country's pre-war housing stock was affected in some way.
For every civilian killed, 35 were forced out of their homes by the blitz.
There is now a strong body of opinion which believes that it was a mistake for the Government to provide Anderson shelters rather than building deep bomb-proof public shelters of the sort promoted by Ramon Perera, who had overseen the building of a large number of such shelters in Catalonia during the Spanish Civil War (1936-1939). British engineer Cyril Helsby helped Perera escape to Britain as Barcelona fell to Franco's troops in 1939, but neither could persuade the British establishment to invest in more substantial shelters which would have saved many lives.
It is possible that Ministers thought that factory, transport and other workers might opt to stay in truly safe shelters rather than return to work after bombs had stopped falling, even though there was no evidence that this had happened in Barcelona. The full story was told in a TV de Catalunya "30 Minuts" documentary, produced in collaboration with Justin Webster Productions and first shown on Spanish TV in 2006.
Reports about the 'Blitz Spirit' and all that need to be received cautiously. History is, after all, written by victors and survivors. People weren't 'heroic'. They had no choice but to do their best to survive in a terrible time. Some felt abandoned by the government, and some Londoners insisted on staying in Tube stations even though this was expressly forbidden at first. Others moaned about the blackout and other restrictions which led to increased deaths caused by falls and road accidents.
For more information I recommend Richard Overy's article The Dangers of the Blitz Spirit.
