The siege of Haarlem was an episode of the Eighty Years' War. From 11 December 1572 to 13 July 1573 an army of Philip II of Spain laid bloody siege to the city of Haarlem in the Netherlands, whose loyalties had begun wavering during the previous summer. After the naval battle of Haarlemmermeer and the defeat of a land relief force, the starving city surrendered and the garrison was massacred. The resistance nonetheless was taken as an heroic example by the Orangists at the sieges of Alkmaar and Leiden.

The siege of Ostend was a three-year siege of the city of Ostend during the Eighty Years' War and the Anglo–Spanish War. A Spanish force under Archduke Albrecht besieged the fortress being held initially by a Dutch force which was reinforced by English troops under Francis Vere, who became the town's governor. It was said "the Spanish assailed the unassailable; the Dutch defended the indefensible." The commitment of both sides in the dispute over the only Dutch-ruled area in the province of Flanders, made the campaign continue for more than any other during the war. This resulted in one of the longest and bloodiest sieges in world history: more than 100,000 people were killed, wounded, or succumbed to disease during the siege.
