The East Kent Gazette, a weekly, reported the disaster on Saturday April 8th, still without further identifying the location. (1) It did add:
Most of the victims were buried in a mass grave in the Faversham cemetery in Love Lane. (2)
Faversham’s population in 1916 was probably around 11,000, (2) though that is Faversham itself, not the neighbouring villages which also provided labour for the munitions works. Still, to realize that 108 dead is roughly 1% of the population is to realize some of the impact of the disaster on local families and townspeople, deserving “many manifestations of public grief” indeed.
