Things being in this state, William left a strong body of men to continue the investment and siege of Arques, and went off himself, at the head of the remainder of his force, to intercept Henry on his advance. The result was a battle and a victory, gained under circumstances so extraordinary, that William, young as he was, acquired by his exploits a brilliant and universal renown.

A dangerous defile.
Henry's order of march.

It seems that Henry, in his progress to Arques, had to pass through a long and gloomy valley, which was bounded on either side by precipitous and forest-covered hills. Through this dangerous defile the long train of Henry's army was advancing, arranged and marshaled in such an order as seemed to afford the greatest hope of security in case of an attack. First came the vanguard, a strong escort, formed of heavy bodies of soldiery, armed with battle-axes and pikes, and other similar weapons, the most efficient then known. Immediately after this vanguard came a long train of baggage, the tents, the provisions, the stores, and all the munitions of war. The baggage was followed by a great company of servants—the cooks, the carters, the laborers, the camp followers of every description—a throng of non-combatants, useless, of course, in a battle, and a burden on a march, and yet the inseparable and indispensable attendant of an army, whether at rest or in motion. After this throng came the main body of the army, with the king, escorted by his guard of honor, at the head of it. An active and efficient corps of lancers and men-at-arms brought up the rear.

William's ambuscade.

William conceived the design of drawing this cumbrous and unmanageable body into an ambuscade. He selected, accordingly, the narrowest and most dangerous part of the defile for the purpose, and stationed vast numbers of Norman soldiers, armed with javelins and arrows, upon the slopes of the hill on either side, concealing them all carefully among the thickets and rocks. He then marshaled the remainder of his forces in the valley, and sent them up the valley to meet Henry as he was descending. This body of troops, which was to advance openly to meet the king, as if they constituted the whole of William's force, were to fight a pretended battle with the vanguard, and then to retreat, in hopes to draw the whole train after them in a pursuit so eager as to throw them into confusion; and then, when the column, thus disarranged, should reach the place of ambuscade, the Normans were to come down upon them suddenly from their hiding-places, and complete their discomfiture.

Its success.
Pretended flight of the Normans.

The plan was well laid, and wisely and bravely executed; and it was most triumphantly successful in its result. The vanguard of Henry's army were deceived by the pretended flight of the Norman detachment. They supposed, too, that it constituted the whole body of their enemies. They pressed forward, therefore, with great exultation and eagerness to pursue them. News of the attack, and of the apparent repulse with which the French soldiers had met it, passed rapidly along the valley, producing every where the wildest excitement, and an eager desire to press forward to the scene of conflict. The whole valley was filled with shouts and outcries; baggage was abandoned, that those who had charge of it might hurry on; men ran to and fro for tidings, or ascended eminences to try to see. Horsemen drove at full speed from front to rear, and from rear on to the front again; orders and counter orders were given, which nobody would understand or attend to in the general confusion and din. In fact, the universal attention seemed absorbed in one general and eager desire to press forward with headlong impetuosity to the scene of victory and pursuit which they supposed was enacting in the van.

Disarray of the French.
Rout of the French.

The army pressed on in this confused and excited manner until they reached the place of ambuscade. They went on, too, through this narrow passage, as heedlessly as ever; and, when the densest and most powerful portion of the column was crowding through, they were suddenly thunderstruck by the issuing of a thousand weapons from the heights and thickets above them on either hand—a dreadful shower of arrows, javelins, and spears, which struck down hundreds in a moment, and overwhelmed the rest with astonishment and terror. As soon as this first discharge had been effected, the concealed enemy came pouring down the sides of the mountain, springing out from a thousand hiding-places, as if suddenly brought into being by some magic power. The discomfiture of Henry's forces was complete and irremediable. The men fled every where in utter dismay, trampling upon and destroying one another, as they crowded back in terrified throngs to find some place of safety up the valley. There, after a day or two, Henry got together the scattered remains of his army, and established something like a camp.
