Battle of Neerwinden
In 1793 an earthen fort was built next to the harbour of Numansdorp. The purpose of this fort was to keep an eye on the shipping between the "Volkerak" and "Hollands Diep". In the same year, France attacked the Austrian Netherlands. Thanks to the Battle of Neerwinden the Austrian Netherlands remain in Austrian hands. In 1795 the Batavian Republic starts.
