Battle of Fleurus (1690) - Prelude

Prelude

Prince Waldeck had hoped to delay the campaign to enable the Elector of Brandenburg to move on the Moselle and tie down Boufflers, but Luxembourg’s early manoeuvres had allowed Boufflers to move between the rivers Sambre and Meuse to support the French commander. Waldeck, meanwhile, left his assembly point at Tienen (Tirlemont) and advanced to Wavre. After dispersing his troops to live off forage, the Allied army reassembled and advanced to Genappe on 8 June.

In mid-June Luxembourg split his forces. Humières was relegated to supervise the garrison of the Lines of the Lys and the Scheldt, whilst the main French army left Deinze and marched south, crossing the River Sambre at Jeumont on 23 June. Meanwhile, detachments from Boufflers force under Rubantel had augmented Luxembourg’s army, which continued its march, camping at Boussu on 27 June.

As Luxembourg manoeuvred south of Mons and Charleroi, Waldeck moved his camp between Nivelles and Pieton on 28 June. That same evening, Luxembourg personally led a detachment from Gerpinnes (together with bridging pontoons), to establish a crossing of the Sambre at Ham. A fortified position at Froidmont (garrisoned by about 100 men) was soon compelled to surrender after artillery was brought across the river; a simultaneous attack by French dragoons seized an enemy redoubt that had been abandoned at the approach of Luxembourg’s army. With the bridgehead secure, the rest of the French army (apart from the heavy baggage that had remained on the south bank at Ham) crossed the Sambre on 30 June. (See map).

Waldeck decamped and moved towards the French bridgehead. French and Dutch cavalry sent out to reconnoitre the area crossed swords in an inconclusive action near Fleurus, but by evening the French cavalry had withdrawn to Velaine where it was joined by the rest of their army, only 3 km (< 2 miles) from the Allies.
