To his war-scarred veterans, Junot, Soult, Jourdan, Suchet, the Emperor mainly intrusted the military expeditions. Still, to save Joseph from a sense of humiliation, the Emperor acted as far as possible through his brother, in giving commands to the army. But the marshals, obedient as children to the commands of Napoleon, whose superior genius not one of them ever thought of calling in question, often manifested reluctance in executing operations directed by Joseph. At times they could not conceal from him that they considered their knowledge of the art of war superior to his. Joseph was king of Spain, and was often humiliated by the impression forced upon him that he was something like a tool in the hands of others. During the year 1809 Joseph remained most of the time in Madrid. There were innumerable conflicts during the year, from petty skirmishes to pretty severe battles, none of which are worthy of record in this brief sketch. The latter part of April the Duke of Wellington landed in Portugal, with English re-enforcements of thirty thousand men. With these, aided by such forces as he could raise in Portugal and rally around him in Spain, he was to advance against the French. Napoleon had been compelled to withdraw all of the Imperial Guard, and all of his choicest troops, to meet the war on the plains of Germany. Marshal Soult was on the march for Oporto. With about twenty thousand troops he laid siege to the city. The feebleness of the defense of the Portuguese may be inferred from the fact that the city was protected by two hundred pieces of cannon, and by a force of regular troops and armed peasants amounting to about seventy thousand men. Soult, having made all his preparations for the assault, and confident that the city could not resist his attack, wrote a very earnest letter to the magistrates, urging that by capitulation they should save the city from the horrors of being carried by storm. No reply was returned to the summons except a continued fire. The attack was made. The Portuguese peasants had tortured, mangled, killed all the French prisoners that had fallen into their hands. Both parties were in a state of extreme exasperation. The battle was short. When the French troops burst through the barriers, a general panic seized the Portuguese troops, and they rushed in wild confusion through the streets toward the Douro. The French cavalry pursued the terrified fugitives, and, with keen sabres, hewed them down till their arms were weary with the slaughter.
