Fleurus (Thirty Years' War).
Fought August 29, 1622, between the Spaniards, under Spinola, and the Palatinate troops, under Count von Mansfeldt and Christian of Brunswick. The Germans were endeavouring to retreat into Holland after their defeat at Hoechst and were intercepted by the Spaniards, through whom they tried to fight their way. In this effort the infantry was almost entirely cut to pieces, but about 7,000 cavalry reached Breda with the two generals.
