Recapture of Douai
Summary
Capitalizing on the crushing victory at Denain, Villars launches a rapid counter-offensive to retake places lost the previous year. Douai, heavily fortified, is encircled in early August. Despite Imperial relief attempts, the garrison is isolated. The French conduct a rigorous siege with bombardments and saps. The town capitulates after a month.
Historical context
Douai, lost in 1710, was a cornerstone of Vauban's system. Its rapid reconquest allows France to regain strategic ascendancy in the north. It is political as much as military revenge.
Tactics
Well-prepared offensive siege: destruction of outer works, constant pounding, diversionary feints to weaken bastions. Coordination of artillery and approach trenches.
Consequences
The capture of Douai reopens access to inland Flanders, breaks Imperial momentum, and scatters their logistics. It strengthens the French position for favorable peace negotiations at Utrecht.
