On the 1st of July, 1918, the deadliest explosion in British history occurred near Chilwell in Nottinghamshire, England.
The disaster happened at National Filling Factory No. 6, a First World War munitions factory that had been in operation since 1915. The factory was known for its “Canary girls“: women shell makers.
On the day of the disaster eight tons of TNT blew up, killing 134 people and injuring 250 others, however newspapers at the time reported a much lower death toll.
The site of the factory is now home to Chetwynd Barracks.
