The English, finding they would not hazard a battle, resolved, if possible, to cross the Oise and advance into the isle of France, and even attack the king's quarters. They decamped therefore on the fourth day from their arrival, and marched in a body to Chanville-haut-Vergier[97]; but as they heard that all the passes on the river were guarded, they determined to execute their plan by night, and they had with them on carts small boats of leather and wood, with cords and other necessaries. They ordered a large detachment to advance to Beaumont, under pretence of their crossing the river and to make a prodigious noise, that the guards at the other passes might be, drawn off to resist their attempt at Beaumont, while the remainder of the army should proceed silently along the river to find out a proper place to cross.
A place was found according to their wish, opposite to the abbey of Beaumont, whence the guards had gone; for all the soldiers near were attracted by the noise at Beaumont, as it had been planned by the English, who, when they saw numbers had been collected, pretended to make an attempt to force a passage, which was quite impracticable should any tolerable defence be made.
The other party of English now launched a boat into the river, and with difficulty three or four passed over, when, having fastened two strong cords to each bank with staves of wood between them, from forty to fifty crossed by this means, and instantly fortified themselves with sharpened palisades, as was their usual custom.
Now, consider the extreme danger the first party that crossed would have been in had only ten Frenchmen staid to guard this pass, who would easily have defended it against the whole power of the duke of York; and this may serve for an example to those who are intrusted with similar commands, never to place any guards but such as they know may be depended on, and such as will have a proper regard to their own honour,—for by neglect the greatest misfortunes may happen.
Shortly after, the men of Floquet, who had had this part of the river in charge, returning from Beaumont, whither they had gone on hearing the shoutings of the English, noticed them crossing the river, and instantly gave the alarm, along the banks, as far as Beaumont, where the greater part of their captains were quartered. They lost no time in mounting their horses, and hastened to where the English were, intending to combat them; but it was lost labour, for they were too numerous, although some skirmishing passed between them.
In these skirmishes, a very valiant man was slain, called William du Châtel, nephew to sir Tanneguy du Châtel, and with him two or three more.
On this bridge of cords the English conveyed over their baggage, carts and stores; and when the French saw that they could not prevent them, they retreated to Pontoise, to inform the king of what had passed, who was greatly displeased at the intelligence. Some of his council, being fearful of the event turning out more disastrous and to their greater shame, had all the artillery and stores moved into the large blockhouse of St Martin, and made every preparation for immediately decamping with the whole army, should it become necessary.
The English, having passed the Oise at their ease, lodged that night on the spot, and there created some new knights,—such as the two brothers of lord Stafford, one of whom styled himself count d'Eu[98]. On the morrow, they dislodged, and marched in handsome order toward Pontoise, and were quartered in two villages. The king, on receiving intelligence of the approach of the English, was advised to remove his quarters from Maubuisson, and march his whole army to Poissy[99], with the reserve of those in the great blockhouse, to the amount of two or three thousand combatants, under the command of the lord de Coetivy, admiral of France. He had also with him La Hire, Joachim Rohault, John d'Estouteville and his brother Robinet, sir Robert de Bethune lord of Moreul in Brie, the lord de Châtillon, the lord de Moyencourt, Regnault de Longueval, the lord de la Roche-Guyon, the lord de Moy in the Beauvoisis, and other gentlemen of renown.
Those who had been sent from Tournay remained there likewise, and great plenty of provision and stores of all sorts had been carried thither. The king, on his departure, had promised to relieve them so soon as possible. With regard to the bulwark at the end of the bridge, the French had abandoned it.
