Battle of Malplaquet
During the War of the Spanish Succession, the Duke of Marlborough in 1709 intended to capture Ypres, at the time a major French fortress, but changed his mind owing to the long time and effort it had taken him to capture Tournai and apprehension of disease spreading in his army in the poorly drained land around Ypres (see Battle of Malplaquet). In 1713 it was handed over to the Habsburgs, and became part of the Austrian Netherlands.
