This was followed by the Battle of Menin on 13 September, in which the French routed a Dutch corps under Prince William of Orange. The Dutch suffered 3,000 casualties and lost 40 field pieces in the disaster. Two days later, an Austrian corps led by Johann Peter Beaulieu routed the French and recaptured Menen (Menin). Coburg's main army concluded the Siege of Le Quesnoy on 13 September 1793, taking 4,000 French troops prisoner. Two French columns attempted to raise the siege but failed, one of the columns being nearly wiped out by Coalition cavalry in the Battle of Avesnes-le-Sec. Though Coburg might have easily seized Cambrai and Bouchain, which had been stripped of their garrisons to form the relief columns, the Coalition commander chose to move against Maubeuge instead. For these defeats, Houchard was arrested on 23 September and incarcerated in a common prison. Denounced as a coward and a traitor by the Revolutionary Tribunal, he was executed by guillotine on 16 November. His predecessor in command of the "Army of the North", Adam Philippe, Comte de Custine had been guillotined on 27 August 1793. Jean-Baptiste Jourdan had been wounded at Hondschoote and was named to lead the "Army of the Ardennes" on 9 September 1793. He was appointed provisional commander in chief of the "Army of the North" on 22 September 1793. When Jourdan protested that he lacked the experience to command the 104,000-man army, the representatives on mission notified him that refusal would result in his arrest. The new commander found that he must respond to the Coalition's move against Maubeuge. Coburg's army began the Siege of Maubeuge on 30 September. On 1 October 1793, Jourdan's large army was distributed across a broad front in four great masses, starting at the North Sea and running southeast. Joseph Souham at Dunkirk commanded 8,852 infantry in 17 battalions and 430 cavalry in one regiment and André Gigaux at Hondschoote had 7,269 infantry in 15 battalions. Near Cassel, Dominique Vandamme led 8,984 foot soldiers in 19 battalions and 325 horsemen in one regiment, while Charles François Filon led 3,705 foot soldiers in nine battalions. At Bailleul there were 4,166 infantry in 10 battalions. The second mass started at Armentières, where there were 9,644 foot in 19 battalions and 1,338 horse in four regiments.
