As soon as the boats had returned he marched with the three companies. When half-way between Valenca and Caminha he met a peasant, who had crossed from the northern bank in a boat that had escaped the search of the French. He reported that some days before some 10,000 of the French had arrived in the neighbourhood of the village Campo Sancos, and that a division had been hard at work since their arrival transporting some large fishing-boats and heavy guns from the harbour of Guardia to Campo Sancos. The guns had been placed in a battery on a height, and the boats launched in a little river that ran into the Minho village. Terence learned that the work was now nearly completed, and the peasant had risked his life in coming across to give information.

Terence at once sent off a mounted man to Valenca to request Herrara to march down with the first battalion and to send on to Macwitty to leave one company to assist the ordenanças to guard the river between Salvatierra and Valenca, and to take post with the other two in front of the latter town. At nightfall he was joined by Herrara.
