Raimondo Montecuccoli
Louis William served first under Raimondo Montecuccoli against Turenne, and then under the duke of Lorraine. At the siege of Vienna by the Turks, in 1683, he threw his forces into the city, and by a brilliant sally effected a junction with Jan III Sobieski and the Duke of Lorraine, who had come to its relief. In 1689 he defeated the Turks at Niš.
