Although the capture of the town would not allow for a Spanish invasion of the Republic, its location between the Rhine and Meuse rivers rendered it strategically significant for both sides, given that the United Provinces greatly benefited from the river trade with the neighboring neutral states and Spain was pursuing a strategy of blockading the waterways which flowed across the Republic to ruin its economy.

Anglo-Dutch troops under the commands of Maurice of Nassau and Francis Vere laid siege to the Spanish garrisoned city. The siege was unique in that the besiegers used a hundred ships, forming a semicircle in a chain on the Mass river to form a blockade. A Spanish force under the command of the Count of Mansfeld attempted to relieve the city in May, but they were defeated and later forced to withdraw. Three Governors of the city were killed – after the last fatality and as a result of the failed relief, the Spanish surrendered the city on 24 June 1593. The victory earned Maurice much fame and had thus become a steadfast strategist in the art of war.
