"We had better fall back, Herrara, before they form a fresh column of attack. We might repulse them again, but they will be able to cross by boats elsewhere, and we shall be taken in front and rear. Let us draw off in good order. The infantry will be sure to march straight against the battery on the hill behind, and it will be half an hour before the cavalry can cross, and by that time we shall be well on our way; whereas, if we stop here until we are taken in flank and rear, we shall be cut to pieces." "I quite agree with you," Herrara said, and ordered the man with the horn standing beside him to sound the retreat. The men near at once formed up and got in motion, those in the houses poured out, and in two minutes the whole force were going up the hill at a trot, but still preserving their order. Five minutes later the head of the French column poured over the bridge. Just as the troops reached the place of encampment the fire of the battery ceased suddenly. CHAPTER XVIII MARY O'CONNOR Never was a large force of men driven from a very strong position, carefully prepared and defended by a vast number of guns, so quickly and easily as were the Portuguese before Oporto. The bishop, after rejecting Soult's summons and disregarding his prayers to save the city from ruin, suddenly lost heart, and after all his boasting, slipped away after dark to the Serra Convent, leaving the command to the generals of the army. The feint which Soult had made with Merle's division the night before against the Portuguese left succeeded perfectly, the Portuguese massing their forces on that side to resist the expected attack. Soult's real intentions, however, were to break through the centre of the line and then to drive the Portuguese right and left away from the town, while he pushed a body of troops straight through the city to seize the bridge and thus cut off all retreat. Accordingly he commenced the attack on both wings. The Portuguese weakened their centre to meet these, and then the central division of the French rushed forward, burst through the intrenchments, and carried at once the two principal forts. Then two battalions marched into the town and made for the bridge, while the rest fell on the Portuguese rear. The French right carried in succession a number of forts, took fifty pieces of artillery, and drove off a great mass of the Portuguese from the town, while Merle met with equal success on the other flank. Half the Portuguese, therefore, were driven up the valley of the Douro, and the other half down towards the sea.
