In 1672, hostilities resumed against the Protestant Republic of the Netherlands and continued in the following years. In 1676, Louis XIV, in an effort to "safeguard the tranquility of his borders for ever" ("assurer à jamais le repos de ses frontières"), focused most of his efforts against Spain and occupied Condé and Bouchain. On 17 March 1677, the French troops stormed Valenciennes and moved toward Cambrai, the strongest place of the Netherlands, which was reached on 20 March. On 22 March, Louis XIV was in the city in person. On 2 April, the French invested in a part of the place. By 5 April, the city surrendered, given the same benefits as Lille in 1667, but the Spanish garrison took refuge in the citadel and the siege continued until 17 April. After 29 days of siege the king made his entry into the city, on 19 April, Easter Monday. Louis XIV named the Marquis de Cesen as governor, and appointed 14 new aldermen while keeping the same provost.
