Terence had already written out his instructions to Herrara in triplicate, and three men were despatched with these. They were warned to be extremely careful, for the men who had first been sent, had reported that the French had posted sentries out on their flanks. One of the messengers was to make a long detour to cross the road half a mile ahead of the French, and then to make his way along on the opposite hillside to the spot where Herrara was posted. The other two were to make their way as best they could through the village. The pieces of paper they carried were rolled up into little balls, and they were ordered that, if noticed and an alarm given, these were at once to be swallowed. Soon after ten o'clock the regiment formed up. Terence had given detailed orders to the captain of each company. These were instructed to call up their men twenty at a time, and to explain their orders to them, so that every man should know exactly what to do. No sound had been heard in the village, and Terence felt sure that Herrara must have received his orders, and at a quarter past ten he with one company moved slowly down towards the village; Bull, with the main body of the force, marching westward along the hills. Six men had volunteered for the service of silencing the French outposts, and these, leaving their muskets behind, stole forward in advance of the company, which halted at some little distance from the French centre. In a quarter of an hour they returned. Eight French sentries had been surprised and killed, the Portuguese crawling up to them until near enough to spring upon and stab them without the slightest alarm being given. The company now moved silently forward again until within a hundred yards of the village, when they halted until the church clock struck eleven. Then they rushed down into the village. As they entered it shots were fired, and an outcry rose from the other side, showing that Herrara had managed matters as well as they had. The surprise was complete; the street was full of horses, while the soldiers had taken shelter in the houses. A scene of the wildest confusion ensued. The horses were shot, for it was most important to cripple this most formidable arm of the French service, and the men were attacked as they poured out of the houses.
