The Battle of Dorking

This short story describes the invasion of England by an unnamed enemy in which the narrator, and 1000 citizens, defend the small English town of Dorking, with no supplies or news of outside events.

The Battle of Dorking, written in 1871, was so popular it started a literary craze for stories that aroused imaginations and anxieties about hypothetical invasions by foreign powers.

I have never heard of this before but apparently, at the time, the book absolutely stunned Britain and was extremely influential in starting the genre of invasion literature.
