The RAF Fauld explosion was a military accident which occurred at 11:11am on Monday, 27 November 1944 at the RAF Fauld underground munitionsstorage depot. The RAF Fauld explosion was one of the largest non-nuclear explosions in history and the largest to occur on UK soil. Between 3,500 and 4,000 tonnes of ordnance exploded—mostly comprising high explosive -filled bombs, but including a variety of other types of weapons and including 500 million rounds of rifleammunition. The explosion crater with a depth of and across is still visible just south of Fauld, to the east of Hanbury in Staffordshire, England. It is now known as the Hanbury Crater. A nearby reservoir containing 450,000 cubic metres of water was obliterated in the incident, along with several buildings including a complete farm. Flooding caused by destruction of the reservoir added to the damage directly caused by the explosion. The exact death toll is uncertain; it is believed that about 70 people died in the explosion.
Cause
The cause of the disaster was not made clear at the time. There had been staff shortages, a management position had remained empty for a year, and 189 inexperienced Italian POWs were working in the mines at the time of the accident. In 1974, it was announced that the cause of the explosion was probably a site worker removing a detonator from a live bomb using a brass chisel rather than a wooden batten. An eyewitness testified that he had seen a worker using brass chisels in defiance of the strict regulations in force.
Effects
Two huge explosions were witnessed at No. 21 Maintenance Unit RAF Bomb Storage dump on 27 November 1944 at 11:15 hours. Eyewitnesses reported seeing two distinct columns of black smoke in the form of a mushroom cloud ascending several thousand feet, and saw a blaze at the foot of the column. According to the Commanding Officer of 21 M.U. an open dump of incendiary bombs caught fire and it was allowed to burn itself out without damage or casualties. Property was damaged within a radius of mile of the crater. Debris and damage occurred to all property within a circle extending for. Upper Castle Hayes Farm completely disappeared and Messrs. Peter Ford's lime and gypsum works to the north of the village and Purse cottages were completely demolished. The lime works was destroyed by the destruction of the reservoir dam and the release of water into the works. Hanbury Fields Farm, Hare Holes Farm and also Croft Farm with adjacent cottages were all extensively damaged. Debris also damaged Hanbury village. The crater was by in length and deep covering 12 acres. Approximately one third of the RAF dump exploded, an area of 65,000 square yards, but barriers of rock pillars between No. 3 and No. 4 sections held and prevented the other munition storage areas from exploding in a chain reaction.
Casualties
At the time, there was no careful tally of the number of workers at the facility. So, while the exact death toll is uncertain, it appears that about 70 people died in the explosion. The official report said that 90 were killed, missing or injured, including:
26 killed or missing at the RAF dump—divided between RAF personnel, civilian workers and some Italian prisoners of war who were working there—5 of whom were gassed by toxic fumes; also 10 severely injured.
37 killed or missing at Peter Ford & Sons, a nearby gypsum mine and plaster mill, and surrounding countryside; also 12 injured.
perhaps seven or so farm workers at the nearby Upper Castle Hayes Farm.
Also 200 cattle were killed by the explosion. Some live cattle were removed from the vicinity but were dead the following morning.
Aftermath
Much of the storage facility was annihilated by the explosion, but the site itself continued to be used by the RAF for munitions storage until 1966, when No. 21 Maintenance Unit was disbanded. Following France's withdrawal from NATO's integrated military structure in 1966, the site was used by the US Army, between 1967 and 1973, to store US ammunition previously stored in France. By 1979 the site was fenced off and the area is now covered with over 150 species of trees and wildlife. The area is restricted as a significant amount of explosives are still buried deep in the site; the UK government has deemed their removal unfeasible on the grounds of cost. On 13 September 1990, 46 years after the initial incident, it was announced that a memorial stone was to be built to remember those who lost their lives. The memorial was to be paid by the public due to Hanbury Parish Council having a lack of funds. The stone used for the memorial was donated by the Italian government and flown to the United Kingdom on an RAF plane. No. 21 MU was the subject of several paintings under the collective title "the bomb store" by David Bomberg. He was briefly employed as a war artist by the War Ministry in 1943.
