The siege of Bonn took place from 3 to 12 November 1673 in Bonn, present day Germany, during the Franco-Dutch War. Having forced the armies of Louis XIV to retreat, the Dutch in 1673 went on the offensive. At Bonn, a garrison consisting of troops from France and the Electorate of Cologne was besieged by a force from the Dutch Republic (commanded by stadtholder William III), the Holy Roman Empire (commanded by Raimondo Montecuccoli), and Spain. The allied forces captured the garrison following a nine-day siege.
In 1689 Bonn was again the site of a major siege.
