On 8 April 1691, after a nine-month siege, Louis XIV’s army stormed the city, which again suffered heavy casualties. From 1697 to 1701, Mons was alternately French or Austrian. After being under French control from 1701 to 1709, the Dutch army gained the upper hand in the Battle of Malplaquet. In 1715, Mons returned to Austria under the terms of the Treaty of Utrecht (1713). But the French did not give up easily; Louis XV besieged the city again in 1746. After the Battle of Jemappes (1792), the Hainaut area was annexed to France and Mons became the capital of the Jemappes district.
