The Portuguese government had reported that guns, provisions, boats, stores and means of carriage had been actually collected for the operation: this was false. The battering train and stores for the attack had therefore to be taken from Elvas, and as it was essential for the safety of the fortress to preserve its armament, and the Guadiana had again carried away the bridge at Jerumenha, that direct line of communication was given up for the circuitous one of Merida, where a stone bridge rendered all safe. But then political difficulties arose. The Portuguese government was on the point of declaring war against Spain, which made the Spanish generals delay assent to the plan of co-operation, and in the midst of this confusion Massena’s advance recalled Wellington to fight the battle of Fuentes Onoro. As Latour Maubourg still held on to Estremadura and foraged the fertile districts, Colonel Colborne, a man of singular talent for war, was sent with a brigade of infantry, some horsemen and guns to curb his inroads. In concert with Count Penne Villemur, a commander of Spanish cavalry, he intercepted several convoys, forced the French troops to quit many frontier towns, and acted with so much address, that Latour Maubourg went into the Morena, thinking a great force was at hand. Colborne then attempted to surprise the fortified post of Benelcazar. Riding on to the drawbridge in the grey of the morning, he summoned the commandant to surrender, as the only means of saving himself from a Spanish army which was coming up and would give no quarter; the French officer was amazed at the appearance of the party, yet hesitated, whereupon Colborne, perceiving he would not yield, galloped off under a few straggling shot and soon after rejoined the army without loss. During his absence, the Spanish generals had acceded to Wellington’s proposition, Blake was in march, the Guadiana had subsided and the siege was undertaken. General William Stewart invested Badajos the 5th of May, on the left bank of the Guadiana, where the principal features were an ancient castle and some out-works. On the 8th General Lumley invested Christoval, an isolated fort or citadel, on the other bank of the Guadiana, which commanded the bridge; but this operation was not well combined, and sixty French dragoons, moving under the fire of the place, maintained a sharp skirmish beyond the walls.
