During the Siege of Maubeuge, Colloredo commanded the 16 battalions, 10 companies, and 8 squadrons, altogether 14,000 Imperial troops, that invested the city on the south bank of the Sambre River. William V, Prince of Orange commanded 12,000 Dutch troops on the north bank. The covering army under Clerfayt numbered 37,000 men, but Coburg spread his forces so wide, that Clerfayt had only 21,000 to meet the attack of Jean-Baptiste Jourdan's 45,000 French soldiers. The Allied cause was not helped when Orange refused to allow any Dutch soldiers to cross to the south bank. After heavy fighting in the Battle of Wattignies on 15–16 October, Coburg abandoned the siege and withdrew the Coalition army.
