The next day Terence heard the sound of the guns on the Serra height, but the distance was too great for the crack of musketry to reach him, and he had no idea that the British were crossing the river until he saw the French marching across the mouth of the valley towards Amarante. Among such veteran troops discipline was speedly recovered, and they encamped in good order in the valley. That town was, however, in the hands of the Portuguese, Loison, either from treachery or incapacity, having disobeyed Soult's orders and retired before the advance of the Portuguese force under Lord Beresford, and, evacuating Amarante, taken the road to Guimaraens, passing by Pombeiro.
He had sent no news to Soult, and the latter general was altogether ignorant that he had left Amarante. Upon receiving the news from the head of the column he at once saw that the position had now become a desperate one. Beresford, he learned at the same time, had marched up the Tamega valley to take post at Chaves, where Silveira had joined him. A retreat in that direction, therefore, was impossible, and he at once destroyed his baggage, spiked his guns, and at nightfall, guided by a peasant, ascended a path up the Serra Catalena, and, marching all night, rejoined Loison at Guimaraens, passing on his way through Pombeiro. Terence had left the place a few hours before, believing that Soult must return up the valley of the Tamega, and, ignorant that Beresford and Silveira barred the way, he marched after nightfall towards Chaves and took up a position where he could arrest, for a time, the retreat of the French army.
He had left two of his men at Pombeiro, and had halted but a short time after completing his long and arduous march when his two men came up with the news that Soult had passed by the very place he had a few hours before left. As there was more than one route open to Soult, Terence was unable to decide which he had best take. His men had already performed a very long march, and it was absolutely necessary to give them a rest; he therefore allowed them to sleep during the day. Towards evening he crossed the Serra de Cabrierra and came down upon Salamende, and sent out scouts for news. Destroying the guns, ammunition, and baggage of Loison's division, Soult reached the Carvalho on the evening of the 14th, drew up his army on the position that he had occupied two months before at the battle of Braga, reorganized his forces, and ordering Loison to lead the advance, while he himself took command of the rear, continued his march. The next day Sir Arthur Wellesley, who had been obliged to halt at Oporto until the whole army, with its artillery and train, had passed the river, reached Braga, having marched by a much shorter road.
Terence's scouts brought news that the whole of the French army were marching towards Salamende. Wholly unsupported as he was, ignorant of the position of Beresford and Silveira, and knowing nothing of Sir Arthur's march towards Braga, he decided not to attempt with his force to bar the way to Soult's twenty thousand men, but to hold Salamende for a time and then fall back up the mountains. Before doing so he sent a party to blow up the bridge at Ponte Nova across the Cavado, and also sent his second regiment to defend the passage at Riuvaens.
Thinking it likely that Soult would again cross the mountains to Chaves, he sent Herrara in command of the force at the bridge, while he himself remained at Salamende. Here he had the houses facing the road by which the enemy would approach, loopholed and the road itself barricaded. Late in the afternoon the French cavalry were seen approaching, and a heavy fire was at once opened upon them. The rapidity of the discharges showed Franceschi that the place was held by more than a mere party of peasants, and he drew off his cavalry and allowed the infantry to pass him. For half an hour the Portuguese held their ground and repulsed three determined assaults; then, seeing a strong body of troops ascending the hillside to take the position in flank, Terence ordered his troops to fall back. This they did in good order, and took up a position high up on the hill.
The French made but a short pause; a small body of cavalry that Soult had left near Braga brought him the news that the British army was entering that town. Scouts were sent forward at once, and their report that the bridge of Riuvaens was destroyed, and that 1,200 Portuguese regular troops were on the opposite bank, decided him to take the road by the Ponte Nova. The night was a terrible one; the rain had for two days been continuous, and the troops were drenched to the skin and impatient at the hardship that they had suffered. The scouts reported that the bridge here had also been destroyed, but that one of the parapets was still unbroken, and that the force on the other side consisted only of peasants. Soult ordered Major Doulong, an officer celebrated for his courage, to take a hundred grenadiers and secure the passage.
A violent storm was now raging, and their footsteps being deadened by the roar of the wind, the French crept up, killed the Portuguese sentry on their side of the bridge before he could give the alarm, and then crawled across the narrow line of masonry. Then they rushed up the opposite heights, shouting and firing, and the peasantry, believing that the whole French army were upon them, fled at once. The bridge was hastily repaired, and at four o'clock in the morning the whole of the French army had crossed. Their retreat was opposed at a bridge of a single arch over a torrent, by a party of Portuguese peasantry, but after two repulses the French, led by Major Doulong, carried it.
They were just in time, for in the afternoon the British came upon a strong rear-guard left at Salamende. Some light troops at once turned their flank, while Sherwood attacked them in front, and they fled in confusion to the Ponte Nova. As the general imagined that Soult would take the other road, their retreat in this direction was for some time unperceived, but just as they were crossing, the British artillery opened fire upon the bridge with terrible effect, very many of the enemy being killed before they could effect a passage. Their further retreat was performed without molestation. The British troops had made very long marches in the hopes of cutting Soult's line of retreat, and as the French, unlike the British, carried no provisions for their march, there was now little hope of overtaking them, especially as their main body was far ahead.
Sir Arthur halted for a day at Riuvaens, where Terence's corps was now concentrated, he having marched there the night he was driven out of Salamende. As soon as the British entered the place, the general inquired what corps was holding it, and at once sent for Terence.
"Let me hear what you have been doing, Colonel O'Connor."
