Ghent was the richest, most populous, and powerful city in the Burgundian Netherlands. The battle was a consequence of Ghent's opposition against a new salt tax.[2] When the city openly declared its rebellion, the Duke assembled an army[a] from neighbouring lands, including southern Flanders,[3] and attacked three fortifications; Schendelbeke, Poeke, and Gavere.[1]
Schendelbeke and Poeke were both taken with little effort and both garrisons were executed.[1] The Burgundian army began its bombardment of Gavere on 18 July.[1] The Ghentenaar relief army arrived on 23 July, not knowing the fort had fallen the day before.[1] Philip, aware of the approach of the Ghentenaar army, drew up his army into battle lines.[1] Finding Philip's army battle ready, the Ghentenaar army formed up.[1]
Battle
The battle began with an artillery exchange, a first for the Burgundian army,[4] and due to the superior range of the Ghentenaar artillery, Philip was forced to move his cannons closer to the enemy.[1] Once in range, the Burgundian artillery began to weaken Ghentenaar morale, and numerous Ghentenaar soldiers fled.[1] A Ghentenaar contemporary source claims a spark ignited an open sack of gunpowder causing an explosion which caused the Ghent cannoners to rout.[4]
Seeing the enemy flee, the Burgundian army charged.[1] Some Ghent soldiers regrouped to counter the charge, but their efforts were useless and casualties were high.[1]
Afterwards
It was feared the Duke would destroy the city completely, but when asked to show mercy he is said to have replied "If I should destroy this city, who is going to build me one like it?"
