Terence found, to his satisfaction, that on the approach of the French most of the boats had been removed to the south side of the river and hauled up the bank. His first order was that anyone acquainted with the position of any boats on the other side of the river should at once inform him of it. It was not long before he heard of some twenty or thirty that had been hidden by their owners on the other side, in order that they might have the means of crossing to escape the French exactions. At nightfall several boats were launched, and parties of men, directed by those who had given information, started to cross the river and bring those boats over. The Minho was at this time in flood and was running with great rapidity, and Terence felt confident that in its present state none of the enemy's cavalry would attempt to cross it by swimming.

He decided on placing the largest part of his force opposite Tuy, as the principal road south passed through this town, and he would here be supported by the guns of the fortress of Valenca. He stationed his first battalion here, with orders to line the river for six miles above and below this spot. Half of the second battalion he left under Macwitty, and with the other half determined to march down towards the mouth of the river. The next morning all the boats returned, bringing those for which they had been searching, and after closely questioning the guides he felt assured that there could be so few remaining that the French would hardly attempt to cross the river in the face of the crowd of peasants--whom they could not but see--lining the southern bank.
