Battle of Neerwinden
After his visit to France, he trod the well-worn path for young German princes of those times and served as a soldier. His family interests were aligned with those of Emperor Leopold I and so he fought again the French in the Nine Years' War and was present at the Battle of Neerwinden in 1693. He continued his military career during the War of Spanish Succession and was actively engaged in the Siege of Lille (1708).
