It was, indeed, a daring and a perilous attempt; a strong force was on the other bank; the shores were steep and rocky, and the stream three hundred yards across. Every means had been taken by Soult to make the passage impracticable. His generals of brigade were in observation on the banks; every point of passage was defended; while the marshal satisfied himself that the bridge was utterly destroyed, as he watched from midnight till daybreak the burning pontoons as they went floating down the current. The only practicable plan that seemed left for Sir Arthur to adopt was to employ the shipping, and land his troops at the débouchement of the Douro; and, in that belief, the French general retired to his head-quarters, from which he could observe the sea-- and, as he expected, watch the disembarkation. Wellesley, aware how dangerously Marshal Beresford was situated, had determined at every hazard to cross the river, and arrangements were instantly made. General Murray was despatched to Avintes to try the ford, and if boats could be found, to send them down the stream,-- the Guards, under General Sherbrooke, were detached to attempt the ferry below the town;--while, from the convent of Santo Agostinho, the British commander directed the main operations in person. A spot was marked on the opposite shore as a favourable place for landing. It was an unfinished building near the bank, and there, the troops first passed over were directed to establish themselves until assistance reached them. To cover this landing-place some guns were quietly got into battery in the convent garden. Every preparation was made--and a fortunate accident obtained the means of passage. A small skiff was discovered hidden in some high rushes, that had concealed it from the French. A few peasants and a Portuguese colonel crossed over, and found some three or four crazy barges, half buried in the mud. These prizes were instantly secured. Three companies of the Buffs jumped in, accompanied by General Paget. The opposite bank was gained,--the dismantled building garrisoned,--and the barges were returning for a fresh detachment, before the French seemed aware of the attempt, and--as it turned out--when it was too late to repel it.
