By October of 1745 the majority of Britain's 22,000 troops in Flanders were back in England fighting the Jacobite Rebellion of 1745. The remaining part of the Confederate army was too weak to oppose the French army under Marshal de Saxe in a field. On a night 7-8 February 1746 French invested Brussels, the key point of Austrian Flanders. It was held by a strong garrison of 18 batts & 8 squadrons totaled about 13,000 under Governor Wenzel Anton, Prince of Kaunitz-Rietberg. French army under de Saxe composed of 42 batts & 102 squadrons totaled about 22,000. French made two breaches in the walls & on 20 of February the garrison asked for a capitulation. French entered in the city on 28th. They took 52 colours & 3 standards as trophies.
