 He drew together 35,000 troops, plus Cambrésis militias, Lorraine troops led by the Marquis de Pont-à-Mousson and a contingent of Spanish troops to attack the city.Knowing that an attack against an army of this size would be pointless, and that staying in the city of Dieppe would be suicidal, Henry (after consulting with the Duke of Longueville and the Duke d'Aumont) decided to go to the city of Arques (today called "Arques-la-Bataille") and to construct important military defenses (raising of areas, rebuilding fortifications).Between 15 and 29 September 1589, the troops of the Catholic League launched several attacks on Arques and the surrounding areas, but the Duke of Mayenne's forces were countered by royal artillery.
