Hill's division was the last, and the rain was pouring down with great force by the time they started. The march, however, was not a very long one, for Beresford's division, which was to operate upon the Upper Duoro, had a long distance to make, and it was necessary that all should be ready for simultaneous action. For this purpose the army halted the next day, and upon the 9th marched to Aveiro on the River Vonga. Here a large flotilla of boats was found, and the Norfolk Rangers with two other regiments were ordered to embark at once. The Portuguese fishermen entered heart and soul into the business, and in perfect silence the little flats were rowed up the lake of Ovar. The soldiers were greatly crowded in the boats, and were glad, indeed, when just as morning dawned they landed at the town of Ovar. By this movement they were placed upon the right flank of Francheschi, the general who commanded the advanced division of the French army. Soon after they had landed the French were attacked in front, and finding their flank turned, and the whole British force, which they had believed to be seven days' march away, in their front, they fell back hastily. To their great disappointment, the Rangers took no share in this the first skirmish of the war. But Hill's orders were not to press on the enemy's rear. Three days more of marching and skirmishing brought them close to the Duoro on the evening of the 11th. The enemy crossed that evening and destroyed the bridge, and during the night the British troops were all brought up, and massed behind the hill called the Serra. This hill stood upon a sharp elbow which the river makes just above the town of Oporto, and the British were here completely hidden from Marshal Soult, who had no idea that they were so close at hand. Indeed, knowing that the bridge was broken and that all the boats had been carefully taken over to that side of the river, the Marshal dreamt not that Sir Arthur would attempt to cross, but imagined that he would take boats lower down near the mouth of the river and there endeavor to cross. To prevent such an attempt Soult had massed his army below Oporto. The troops were ordered to pile arms, and eat their breakfast, but to keep in position. "I wonder how we are to cross the river, Tom?" Peter said. "It is three hundred yards across, with a rapid current, no man in the world could swim that, and carry his musket and ammunition across." "I expect Sir Arthur is reconnoitering, Peter; I saw him go up the hill to that convent there; he must be able to see from there right over Oporto."
