The constable marched to besiege the town of St Remy du Plain, and sent sir Anthony de Craon, with a large force to Vernon, to escort the cannons, bombards, and other military engines, to St Remy. There were in company with the constable, his nephew John of Luxembourg, sir Philip de Harcourt and his brother sir James, the lord de Beausault, the vidame of Amiens, the lord d'Offemont[3], the lord de Canny, the borgne de la Heuse, Roux de Neele, Raoul son to the vidame of Amiens, the lord de Lovroy, le Galois de Renty[4], sir Bort Queret, the lord de Herbainnes, the lord de Saine, and many noble knights and esquires, to the number of twelve hundred helmets, and a large body of archers. They quartered themselves within the town of St Remy, and around the castle, which was tolerably strong and well garrisoned with men at arms, and summoned it to surrender to the king's obedience; but on a refusal, some engines were pointed against the walls, which did them much damage. During this time, the lord de Gaucourt, sir John de Dreues, sir Jean de Guarenchieres, Guillaume Batillier, the lord d'Argiellieres, John de Falloise, with other captains of the Orleans and Alençon party, assembled a considerable body of combatants, with the intent of making an unexpected attack on the constable and taking him by surprise. In consequence, they marched on the 10th day of May from their place of rendezvous, and, riding all night, came towards the end of it very near their adversaries. The latter were, however, day and night on their guard, and had spies and scouts dispersed over the country. Morlet de Mons, Galien bastard of Auxi, and others, were on guard when the Armagnacs approached. They made Morlet de Mons and Galien prisoners; but the rest escaped, and, galloping as fast as their horses could carry them to the main army, shouted out, 'To arms, to arms!' adding, that the Armagnacs were advancing in battle-array toward the camp, and had already made prisoners of Morlet and Galien, with some others. The constable, hearing the noise, ordered his men to arm without delay, and dispatched the lord de St Legier and the lord de Drucat, two well experienced knights, to examine and report the truth of this alarm. They had not gone far before they saw the enemy advancing, as had been said, on which they returned to inform the constable of it. He immediately caused his banner to be displayed, and his trumpets sounded, and, sallying out of his tent with a part of his men, drew them up in battle-array to receive the enemy, and urged the remainder of his men to make haste to join him. When he had mounted his horse, he rode along the line, to post his army most advantageously, and exhorted the whole, in the kindest manner, to combat boldly the enemies of the king and crown of France.
