In the meantime Paget's division had marched to Albergaria, while Cotton's division and Trant's command moved to turn Franceschi's position on its right. The darkness and their ignorance of the roads prevented the movement being attended with the hoped-for success. Had the operation been carried out without a hitch, Franceschi and Mermet would both have been driven off the line of retreat to the bridge of Oporto, and must have been captured or destroyed. As it was, Franceschi fell back fighting, joined Mermet's division at Crijo, a day's march in the rear, and although the whole were driven on the following day from this position, they retired in good order, and that night effected their retreat across the bridge of boats, which was then destroyed. As Franceschi's report informed Soult that the whole force of the allies was now upon him, he at once sent off his heavy artillery and baggage by the road to Amarante. Mermet was posted at Valongo, with orders to patrol the river and to seize every boat. Those at Oporto were also secured. On the morning of the 12th the British force was concentrated behind the hill of Villa Nova, and Sir Arthur took his place on the top of the Serra Convent, from whence he commanded a view of the city and opposite bank. He saw that the French force was stationed for the most part below Oporto. Franceschi's report had led Soult to believe that Hill's division had come by sea, and he expected that the transports would go up to the mouth of the Douro, and that the British would attempt to effect a landing there. The river took a sharp turn round the Serra Convent, and Sir Arthur saw that another large convent on the opposite bank, known as the Seminary, was concealed by the hill from Soult's position, and that it might be occupied without attracting the attention of the French. After much search a little boat was found; in this a few men crossed and brought back two large boats from the opposite side of the river. In these the troops at once began to cross, and two companies had taken possession of the convent before Soult was aware of what was going on. Then a prodigious din arose. Troops were hurried through the town, the bugles and trumpets sounded the alarm, while the populace thronged to the roofs of their houses wildly cheering and waving handkerchiefs and scarves, and the church bells added to the clamour.
