The whole of the vassals of France were gathering by the orders of the king at St. Denis. The English fleet had now left the coast, and Edward had only the choice of retreating through Normandy into Brittany or of attempting to force the passage of the Seine, and to fight his way through France to Flanders. He chose the latter alternative, and marched along the left bank of the river towards Paris, seeking in vain to find a passage. The enemy followed him step by step on the opposite bank, and all the bridges were broken down and the fords destroyed. Edward marched on, burning the towns and ravaging the country until he reached Poissy. The bridge was as usual destroyed, but the piles on which it stood were still standing, and he determined to endeavour to cross here. He accordingly halted for five days, but despatched troops in all directions, who burned and ravaged to the very gates of Paris. The villages of St. Germain, St. Cloud, Bourg la Reine, and many others within sight of the walls were destroyed, and the capital itself thrown into a state of terror and consternation. Godfrey of Harcourt was the first to cross the river, and with the advance guard of English fell upon a large body of the burghers of Amiens, and after a severe fight defeated them, killing over five hundred. The king himself with his whole force passed on the 16th of August. Phillip, with his army, quitted St. Denis, when he heard that the English army had passed the Seine, and by parallel marches endeavoured to interpose between it and the borders of Flanders. As his force was every hour increasing he despatched messengers to Edward offering him battle within a few days on condition that he would cease to ravage the country; but Edward declined the proposal, saying that Phillip himself by breaking down the bridges had avoided a battle as long as he could, but that whenever he was ready to give battle he would accept the challenge. During the whole march the armies were within a few leagues of each other, and constant skirmishes took place between bodies detached from the hosts. In some of these skirmishes Walter took part, as he and the other newly made knights were burning to distinguish themselves. Every day the progress of the army became more difficult, as the country people everywhere rose against them, and several times attempted to make a stand but were defeated with great loss. The principal towns were found deserted, and even Poix, which offered great capabilities of defence, had been left unguarded. Upon the English entering, the burghers offered to pay a large ransom to save the town from plunder. The money was to be delivered as soon as the English force had withdrawn, and Walter Somers was ordered by the king to remain behind with a few men-at-arms to receive the ransom.
