The Burgundian army advanced and occupied St. Denis, thence the duke sent detachments to the various gates of Paris in hopes that the populace would rise in his favour. However, the citizens remained quiet, and the duke, being unprovided with the engines and machines necessary for a siege, fell back again, placing strong garrisons in Compiègne and Soissons. Then the Orleanists took the offensive, besieged and captured town after town, and revenged the murder of their friends in Paris by wholesale massacres and atrocities of the worst description. The Burgundians in vain attempted to raise an army of sufficient strength to meet that of the king, who himself accompanied the Orleanist forces in the field. The fact that he was present with them had a powerful influence in preventing many lords who would otherwise have done so from joining Burgundy, for although all knew that the king was but a puppet who could be swayed by those who happened to be round him, even the shadow of the royal authority had great weight, and both parties carried on their operations in the king's name, protesting that any decrees hostile to themselves were not the true expression of his opinion, but the work of ambitious and traitorous persons who surrounded him. After occupying Laon, Peronne, and other places, the king's army entered Artois, captured Bapaume, and advanced against Arras, where Sir John of Luxemburg, who commanded a Burgundian garrison, prepared for the siege by sending away the greater part of the women and children, and destroying all the buildings and suburbs outside the walls.
