But, after eighteen months, they had formed only one company, whilst, as Wellington informed the Government, there was no French _corps d'armée_ which had not a battalion of them. This first British company of sappers and miners came out on the 19th of August, and were immediately set to work. Sir George Collier sent his sailors to assist, and on the 31st Wellington considered that he had made sufficient breach for storming. But that morning Soult sent across the Bidassoa a strong body of French to attack the besiegers. These were met by a division of eight thousand Spaniards, who allowed the French to ascend the heights of San Marcial, on which they were posted, and then, with a shout, charged with the bayonet down hill, at which sight the French instantly broke, and ran for it. They were pursued to the river, in which many plunged, and were drowned. In the afternoon Soult sent over again fifteen thousand men, having put across a pontoon bridge. These, under the eye and encouragement of Lord Wellington, were charged again by the Spaniards, and routed as before; many again rushing into the river, and the rest, crushing upon the bridge, broke it down, and perished in great numbers also. The Portuguese troops likewise met and defeated another detachment of French, who had come by another way. These were supported by British troops, under General Inglis, and with the same result. Wellington was highly delighted to see the Spaniards thus, at length, doing justice to their native valour under British discipline, and praised them warmly. Soult is said to have lost two thousand men.
