During the period of Sir John Moore’s campaign in Spain, Sir John Craddock had been appointed to the command of the British troops in Portugal. Their number was small, and varied considerably during the winter; some detachments which had been sent to Sir John Moore returned without having effected their junction, and many stragglers and sick from that army found their way into Portugal, and were formed into battalions. The brigade under Major General R. Stewart was also incorporated with the army under the orders of Sir John Craddock.
Before the retreat of Sir John Moore was known in England, a corps, under the orders of Major General Mackenzie, had been sent to Cadiz, with the view of being admitted as the garrison of that place. The conduct of the Spaniards, in refusing to allow the British army to enter Ferrol, although pressed by a superior enemy, made it necessary for the Government of England to secure a point of safety for its fleet and armies, before it could consent to the further co-operation of any British force in Spain. It therefore required, as a condition to the employment of an army for the defence of the southern provinces of the Peninsula, that a British force should be admitted within the walls of Cadiz. Much negotiation took place upon this point, but the Spanish Government at last refused the permission, and thus put an end to the proposed assistance of a British army.
The corps under Major General Mackenzie sailed from Cadiz to Lisbon, and added to the force under Sir John Craddock.
After the evacuation of Corunna, by Lieutenant General Sir John Hope, the French had entered it with two corps, those of Marshals Ney and Soult; the latter was detached, about the beginning of February, to the attack of Portugal. He succeeded, with little opposition, in occupying the country to the north of the Douro. In Oporto, the Portuguese force was collected to a considerable amount; but having neither discipline nor regularity, it was unable to oppose more than a feeble resistance to the French. Marshal Soult, who was anxious to strike terror amongst the inhabitants of Portugal, permitted his soldiers, after storming the town, and destroying an immense number of people, to continue their cruelties during several days. The plunder of the place was accompanied with every description of outrage; but the measure only succeeded in increasing the detestation in which the enemy was held, without effecting the subjugation of the country.
After the success of Buonaparte in the centre of Spain, and the expulsion of the English army from Gallicia, General Victor had been detached against the Spanish corps of General Cuesta, which was quartered about Medellin. After some previous movements a general battle was fought, in which the Spanish army was completely routed; it retired to the mountains about Monasterio, where, with the assistance of the reinforcements which were sent to it, it made head against the French army. Victor at this time concerted with Marshal Soult, in Oporto, a combined attack upon the unconquered provinces of Portugal. Soult was to move through Coimbra, upon Lisbon; while Victor was to co-operate from the Spanish frontier, through Portalegre, or Alcantara, upon Abrantes, and from thence to march upon the capital. Sir John Craddock had collected the British force, which had now become respectable from the different reinforcements which had arrived, in positions in front of Santarem, and upon the road to Coimbra, so as to be prepared to move upon either of the two French corps, which threatened to advance upon him. But on the 22nd of April, Sir Arthur Wellesley (who had been selected for the command in Portugal) arrived with some reinforcements, and assumed the direction of the army.
He decided to proceed instantly against the corps under Marshal Soult, in Oporto. He left a division under Major General Mackenzie, with the brigade of heavy cavalry under Major General Fane, at Abrantes, to watch the corps of Marshal Victor: some Portuguese were placed to observe the bridge of Alcantara, and with the rest of the army he proceeded to the Douro. By the rapidity of his movement, Sir Arthur Wellesley disconcerted the plans of the French; he drove their advance guard, in three days, from the Vouga to Oporto, and arrived on the Douro, opposite to that town, upon the 11th of May.
Sir Arthur Wellesley had detached Marshal Beresford, (who had lately been appointed to the command of the Portuguese army,) to pass the Douro, near Lamego, and to occupy Amaranthe; he had also directed General Silviera with the troops under his command, to retain possession of Chaves. By these movements he had hoped to enclose the French corps, in the north of Portugal. On the morning of the 12th he determined to cross the Douro, in face of the enemy, and to attack the town of Oporto, although the bridge had been destroyed, and the boats (with the exception of two that conveyed over the first soldiers) had been removed to the opposite side of the river.
No operation could be more difficult, or require greater bravery in the troops to execute, or talent in the general to combine; but complete success attended it. Marshal Soult was surprised; the British army passed the river in spite of every obstacle, and of the superior numbers which were brought to overwhelm the first regiments that crossed; and the French army was driven, with the loss of its sick and wounded, of great part of its baggage, and of a considerable number of guns, from the town of Oporto. Sir Arthur Wellesley pursued the French on the following day; Marshal Beresford had driven them from Amaranthe; so that, being pressed on all sides, they were obliged to abandon the whole of their guns and baggage, and to fly the country by the mountain roads to Orense; their rear was several times attacked, but the main body could not be attained; and Sir Arthur Wellesley, unable any longer to pursue an enemy who had abandoned every thing which constitutes an army, and who fled without artillery, baggage, or equipment, halted on the 18th at Monte Alegre, and gave up the pursuit.
This short campaign, of only ten days, is perhaps the most brilliant that ever has been executed. Marshal Soult, represented as the best officer in the French army, had occupied the northern provinces of Portugal, for upwards of two months; he had contemplated the entire conquest of the country, and was employed in organizing the necessary means. To defend himself from any attack, he had the Vouga, and the Douro, both formidable rivers, and the advantage of the strongest country in the Peninsula; he had a force equal in amount to the British, or within very little of it, and in a state of superior military organization. He had a perfect knowledge of the country; he commanded its resources; and was in every way formidable from his talents and his means. Yet the genius of Sir Arthur Wellesley deprived him at once of the advantages of which he was possessed. In the space of four days he was driven from Coimbra to the Douro; and in six days after, not having had the time or opportunity of defending himself in a single position, he was chased from the frontiers of Portugal.
The movements of the Portuguese about Chaves had disappointed the expectations of Sir Arthur Wellesley, or his triumph would have been more complete. He had entertained the hope of surrounding the French army; but by the non-execution of a part of his plan the individuals who composed it escaped; but there never was a more disgraceful escape; or a retreat (if it deserve that name, and not a flight) more humiliating to the officer who conducted it.
