"It will not be necessary to watch the river above Campo Sancos, for it would be impossible to row heavy fishing-boats against this stream, so they must land somewhere between that place and the mouth of the river. Thus we have only some eight miles to guard, and as we have eighteen hundred men, besides the peasants, we ought to be able to do that thoroughly. I expect they will endeavour to make the passage to-night, and they will certainly cross, as nearly as they can, opposite the village. The battery is about a mile below it, and is no doubt intended to cover their landing. I shall post myself with two companies of the first battalion there, and extend another company from that point up to Campos Sancos. You, with the other three companies and the three companies of the second battalion, will watch the river below. "It is unlucky that there is no moon at present. I do not expect, however, that the attack will take place till morning, for, in the first place, the peasant said that although the guns had been got up to the height they had not yet been placed in position, and as we have noticed no movement there all day, nor seen a French soldier anywhere near the river, they will only be beginning work now, and can hardly have finished it until well on in the night. Besides, when the first party who crossed have obtained a footing here, the boats will have to go backwards and forwards. No doubt the cavalry will be among the first to cross, and they would hardly get the horses on board in the dark. It is of vital importance to repel this attack, for if the French got across they would be at Vianna to-morrow evening, and at Oporto three days later. I don't suppose that place will resist for a day; and if, as is probable, Victor moves up from the south, he and Soult may be in front of Lisbon in ten days' time. "You had better tell your captains this, in order that they may understand how vital it is to prevent the passage. From what I hear from the peasants, the boats will not be able to carry more than three or four hundred men, and wherever they land we ought to be able to crush them before the boats can cross again and bring over reinforcements." "Well, Bull, I think we are likely to have fighting tonight," Terence said, as Herrara marched off with his men. "I hope so, sir. I don't think they will be able to cross in our face, and it will do the men a lot of good to win the first fight."
