Passage: There was interest in his ideas but they remained untested; this changed with the outbreak of the 1688-1697 Nine Years War which placed great emphasis on manoeuvre and siege warfare. Van Coehoorn was present at the capture of Kaiserswerth and Bonn in 1690; his exact role is unclear but Frederick of Prussia was impressed enough to offer him a position as Major-General in his army. He refused and in 1691 William appointed him commander of Namur where he was finally able to implement his ideas on defensive strategy. Namur was divided into the 'City' on the flat northern bank of the River Sambre and the Citadel on high ground to the south controlling access to the Sambre and Meuse rivers. Van Coehoorn strengthened the 'inner' Citadel with new outworks at Fort William and La Casotte but did not have time to do the same for the 'outer' City area. His garrison of 5,000  was also too small for the active defence he had planned, many being poorly-trained Spanish troops with little interest in fighting for the Dutch.

How many years after Van Coehoorn participated in the capture of Kaiserswerth and Bonn was he appointed commander of Namur? How many years after being offered a position as Major-General was Van Coehoorn appointed commander of Namur? How many years after the Nine Years War started was Kaiserswerth and Bonn captured? How many years after the capture of Kaiserswerth and Bonn did William appoint Van Coehoorn commander of Namur? How many years after the outbreak of the Nine Years War did the capture of Kaiserswerth and Bonn occur? Namur was divided into the city and what else? When did Van Coehoorn refused Frederick of Prussia the position he offered him? Where was his garrison of 5000 too small for the active defense he had planned? Which area of Namur failed to be strengthened as the inner Citadel took priority? Which area was strengthened, the 'inner' Citadel or the 'outer' City area? Which happened first, the capture of Kaiserswerth or Van Coehoorn's appointment to Namur? Who refused a position as Major-General? Who refused to appoint him commander of Namur? Who was appointed as the commander of Namur? Who was offered a position as Major-General?
