As a response to Napoleon's movements, on 15 June, II Corps were posted west and southwest of Brussels, with a cavalry screen. Wellington's forward army engaged the French at Quatre Bras on 16 June, but he later fell back to remain in contact with his Prussian allies, who had retreated following the Battle of Ligny, and took position near the village of Waterloo.
