Le Quesnoy
Jean Henri Becays Ferrand surrendered Valenciennes to the Coalition on 27 July 1793. At this point the Coalition allies made a deadly blunder. Having seized Condé and Valencienes, they had 118,000 troops concentrated at the gap in the fortress line. Instead, they split their forces. Their next targets were Dunkirk, invested on 24 August, and Le Quesnoy, invested on 28 August. The siege of Le Quesnoy concluded successfully on 13 September but the siege of Dunkirk was a failure.
