O’Donell’s first care upon resuming the command of the army was to strengthen Tortosa and provide it against the siege, which if he could not prevent he would use every exertion to impede and frustrate. Lili arrived there in the middle of July, and a convoy of provisions with him: Velasco then left the place, and retired to Tarragona, broken in health. Stores and men were introduced till the magazines were fully replenished, and the garrison amounted to 8000 effective men. On the night of the 21st the enemy made another attack upon the tête-du-pont, as unsuccessfully as before. Some days afterwards O’Donell came there to inspect the place; he thanked the inhabitants for the good-will which they were manifesting, and the readiness with which they had cut down their fruit-trees and demolished their villas in the adjoining country, sacrificing every thing cheerfully to the national cause. He directed also a sally, which was made with good effect, ♦AUG. 3.♦ some of the enemy’s works being destroyed: Lili was present in this affair, and was wounded. Having seen that every thing was in order here, and promised well, the general returned to his army. But O’Donell deriving no support from either of the neighbouring provinces, had on the one hand to impede Suchet’s operations, and on the other to act against Macdonald. Before that Marshal could take any measures in aid of the besieging army, he had to introduce a convoy ♦MACDONALD ENTERS THE PLAINS OF TARRAGONA.♦ into Barcelona. Having effected this object, and baffled the force which endeavoured to prevent it, he moved upon the Ebro; by this movement O’Donell was compelled to withdraw the division which kept in check the French corps upon the left bank; and Suchet, seizing the opportunity, passed that corps across the river, and advanced against the Valencian army, with which Caro had at last taken the field, ... only to make a precipitate retreat when it was thus attacked, and leave the enemy without any interruption from that side. Macdonald meantime easily overcoming the little resistance that could be interposed entered the plain of Tarragona, and took a position at Reus, with his whole disposable force, raising contributions in money and every kind of stores upon that unhappy town, while his troops pillaged the surrounding country. Tarragona was at this time but weakly garrisoned, and some apprehension was entertained that it might be his intention to lay siege to it. Campoverde’s division, therefore, was immediately removed thither from Falset, and O’Donell himself entered the place, and occupied the height of Oliva and the village of La Canonja, endeavouring by activity and display to make the most of his insufficient force. Before daybreak this latter post was attacked by the French in ♦AUG. 21.
