The Battle of Seneffe took place on 11 August 1674 near Seneffe in present-day Belgium and was one of the most notable engagements of the Franco-Dutch War. It was fought between a primarily French force commanded by Condé and a combined Dutch, Imperial, and Spanish force under William of Orange.
One of only three battles in the Spanish Netherlands during the war, Seneffe was the most expensive in terms of casualties, although estimates vary considerably. After successfully repulsing the Allied assault, Condé launched a series of counter-attacks against the advice of his subordinates. Fighting continued into the evening and both sides suffered heavy casualties with no concrete result. After holding his position overnight, William retired the next day in good order.
While the battle ended Allied hopes of invading Northern France, William quickly replaced his losses and Condé was forced onto the defensive thereafter. French losses shocked Louis XIV who thereafter focused on sieges, which were far less costly in terms of casualties.
