This was exactly what happened in Spain. Napoleon's strategy had laughed at the military formation of Frederick the Great's system; the guerrillas of Spain laughed at the formations of regular warfare in any shape. They rose to fight, and dispersed for safety, leaving their smarting foe unable to strike for lack of a billet. The occasional successes of the Spanish regulars showed, moreover, that the generals were not entirely ignorant of Napoleon's own system. When Joseph entered Madrid the whole land was already in open rebellion, except where French force compelled a sullen acquiescence in French rule. The long inactive, sluggish ecclesiastics suddenly seemed to feel the vigor to resist and the power to lead. They joined the insurgents, and invoked the orthodoxy of the nation so as to inflame the passions of the masses against the persecutor of the Pope. Irregular and undefined as were the elements of the uprising, it was nevertheless essentially a popular movement; as Napoleon himself later admitted, it was the people themselves who refused to ratify his new institutions, and who declared for Ferdinand VII. The sequel furnished ample illustration of this fact: the mountaineers of Asturias rose in united rebellion; the inhabitants of Cartagena threw open their arsenals to the volunteers of the neighborhood; the citizens of Saragossa beat off their besiegers, while those of Valencia first massacred the French who took refuge in their citadel, and then repulsed Moncey in a desperate conflict. When the Spanish leaders ventured into an open battle-field they were defeated; on the other hand, when they kept the hills and fought like bandits they were victorious.
