Siege of Douai
Summary
After their costly victory at Malplaquet, the Allies resume the offensive in spring 1710. The siege of Douai, a strategic fortress, lasts more than two months. The French garrison, well commanded by General Albergotti, holds firm despite overwhelming enemy numerical superiority. The Allies must advance slowly under heavy fire. The town finally capitulates but obtains honorable terms.
Historical context
Douai was one of the last locks in the French defensive system in Flanders. Its loss weakened the northern defensive line and allowed the Allies to plan successive sieges in Artois. The siege, opened on 22 April 1710, was conducted jointly by the Prince of Orange and the Prince of Anhalt-Dessau against the garrison of Lieutenant-General Albergotti, entrenched in the fortress and in the Scarpe fort.
Tactics
Methodical siege with parallel trenches and breaching batteries. The French garrison mounted night sorties to destroy enemy works. The defense held out for a long time thanks to Vauban's fortifications, but yielded to exhaustion of supplies. From 24 May to 4 June, Villars attempted to relieve the fortress and faced Marlborough and Eugene on the plain of Lens, but withdrew without giving battle; the siege then resumed until the surrender of 25 June.
Consequences
The fall of Douai triggered a domino effect on neighboring strongholds. It weakened French morale and exposed Béthune, Aire-sur-la-Lys, and Saint-Venant to further offensives. Albergotti obtained the honors of war and evacuated the fortress on 29 June with around 4,500 men; the garrison had lost nearly 3,000 men, while the besiegers suffered about 8,000 killed or wounded.
