Jemappes (pronounced as /fr/; in older texts also: Jemmapes; wa|Djumape; pcd|Djumappes) is a sub-municipality of the city of Mons located in the province of Hainaut, Wallonia, Belgium. It was a separate municipality until 1977. On 8 June 1870, Flénu was detached from Jemappes, and was later merged into Jemappes in 1971. On 1 January 1977, Jemappes was merged into Mons.[1]
Jemappes is known for the Battle of Jemappes between the French and Austrian armies in 1792.
During the French occupation of Belgium (1792–1814), there was a département named after the Battle of Jemappes, Jemmape. Jemappes was also a battleground in the First World War.
