The assault on Brussels or siege of Brussels occurred during the War of the Spanish Succession, from 22 to 27 November 1708 involving French and pro-Bourbon Spanish troops under Maximilian of Bavaria against the garrison and citizens of the city of Brussels.
While the army of the Grand Alliance was occupied with the Siege of Lille, the Elector of Bavaria, Maximilian, made an attempt to capture Brussels. He believed the city, with its weak defenses and small garrison, would be an easy target. Despite his confidence the Allies were forewarned of the plan and had already reinforced Brussels' garrison.
Maximilian, expecting a swift victory, faced strong resistance from Colonel Pascale, the governor of Brussels, and his well-prepared garrison.
