The French army captures the town of Cambrai held by Spanish troops.

The siege of Cambrai took place from 20 March to 19 April 1677 during the 1672–1678 Franco-Dutch War; then part of the Spanish Netherlands, it was invested by a French army under the duc de Luxembourg. Siege operations were supervised by the military engineer Vauban; Louis XIV was nominally in command but played little part in operations.
