Terence went at once up the hill, to a point whence he could look well over the round hills on the other side of the valley, and make out the British and Spanish lines, stretching to Talavera. The troops were already formed up, in readiness for action. Away to his left came the roll of heavy firing from the cork woods near the Alberche and, just as his three officers joined him, the British troops issued pell mell from the woods. They had, in fact, been taken entirely by surprise; and had been attacked so suddenly and vigorously that, for a time, the young soldiers of some of the regiments fell into confusion; and Sir Arthur himself, who was at a large house named the Casa, narrowly escaped capture. The 45th, however, a regiment that had seen much service, and some companies of the 60th Rifles presented a stout front to the enemy. Sir Arthur speedily restored order among the rest of the troops, and the enemy's advance was checked. The division then fell back in good order, each of its flanks being covered by a brigade of cavalry. From the height at which Terence and his officers stood, they could plainly make out the retiring division, and could see heavy masses of French troops descending from the high ground beyond the Alberche. "The whole French army is on us!" Macwitty said. "If their advance guard had not been in such a hurry to attack, and had waited until the others came up, not many of Mackenzie's division would have got back to our lines." It was not long before the French debouched from the woods and, as soon as they did so, a division rapidly crossed the plain towards the allies' left, seized an isolated hill facing the spur on to which Donkin had just hurried up his brigade, and at once opened a heavy cannonade. At the same time another division moved towards the right, and some squadrons of light cavalry could be seen, riding along the road from Madrid towards the Spanish division. "They won't do much good there," Terence said, "for the country is so swampy that they cannot leave the road. Still, I suppose they want to reconnoitre our position, and draw the fire of the Spaniards to ascertain their whereabouts. They are getting very close to them and, when the Spaniards begin, they ought to wipe them out completely." At this moment a heavy rattle of distant musketry was heard, and a light wreath of smoke rose from the Spanish lines. The French cavalry had, in fact, ridden up so close to the Spaniards that they discharged their pistols in bravado at them. To this the Spaniards had replied by a general wild discharge of their muskets. A moment later the party on the hill saw the right of the Spanish line break up as if by magic and, to their astonishment and rage, they made out that the whole plain behind was thickly dotted by fugitives. "Why, the whole lot have bolted, sir!" Bull exclaimed. "Horse and foot are making off. Did anyone ever hear of such a thing!"
