In 1937, 450,000 square feet of disused gypsum workings next to Peter Ford’s plaster works were purchased by the Air Ministry for weapons storage during the Second World War. The RAF venture into underground storage was one of disaster and tragedy. The depot at Fauld became the site of the largest explosion in the UK, when 3,670 tons of bombs stored underground exploded en masse. After the explosion there was a mushroom cloud, about 50 yards wide and upwards out of sight. Mounds of earth weighing up to a ton in weight fell to the ground. Afterwards a fine dust up to 4 inches thick fell, and it was possible to walk without making any noise. A crater, half a mile across and 100 feet deep was left behind. Firefighters from Burton, Stafford and Lichfield attended. At the depot, both R.A.F. personnel and Italian prisoners of war were employed. Both airmen and Italians were killed in the blast. The entire mine was not destroyed, but the hills housing the mine completely disappeared. Access to the remaining tunnels opened up in late 2012, the location was kept very quiet and is now sealed again. I have only just decided to post these photos as it seems several forums have released them from there ‘private’ sections. Glad we got in while still could. Enjoy.
