In the early days of September the situation of the invaders was most perilous. After the disastrous failure of the second siege of Gerona, it will be remembered that Reille had withdrawn to Figueras, close to the French frontier, while Duhesme had cut his way back to Barcelona, after sacrificing all his artillery and his baggage on the way. Both commanders proceeded to report to the Emperor that there was need for ample reinforcements of veteran troops, or a catastrophe must inevitably ensue. Meanwhile Reille preserved a defensive attitude at the foot of the Pyrenees; while Duhesme could do no more than hold Barcelona, and as much of its suburban plain as he could safely occupy without risking overmuch his outlying detachments. He foresaw a famine in the winter, and devoted all his energies to seizing and sending into the town all foodstuffs that he could find in the neighbourhood. His position was most uncomfortable: the late expedition had reduced his force from 13,000 to 10,000 sabres and bayonets. The men were demoralized, and when sent out to forage saw _somatenes_ behind every bush and rock. The populace of Barcelona was awaiting a good opportunity for an _émeute_, and was in constant communication with the insurgents outside. The blockade was not as yet kept up by any large section of the Captain-General’s regular troops, nor had any attempt been made to run lines around the place. It was conducted by an elastic cordon of four or five thousand _miqueletes_, supported by no more than 2,000 infantry of the regular army and possessing five or six field-guns. The charge of the whole line was given to the Conde de Caldagues, who had so much distinguished himself in the previous month by his relief of Gerona. He had been entrusted with a force too small to man a circuit of twelve or fifteen miles, so that Duhesme had no difficulty in pushing sorties through the line of Spanish posts, whenever he chose to send out a sufficiently strong column. But any body that pressed out too far in pursuit of corn or forage, risked being beset and mishandled on its return march by the whole of the _somatenes_ of the country-side. Hence there was a limit to the power to roam of even the largest expeditions that Duhesme could spare from his depleted garrison. The fighting along the blockading cordon was incessant, but never conclusive. On September 2 a strong column of six Italian battalions swept aside the Spaniards for a moment in the direction of San Boy, but a smaller expedition against the bridge of Molins de Rey was repulsed. The moment that the Italians returned to Barcelona, with the food that they had scraped together in the villages, Caldagues reoccupied his old positions. There were many skirmishes but no large sorties between September 2 and October 12, when Milosewitz took out 2,000 men for a cattle-hunt in the valley of the Besos. He pierced the blockading line, routing the _miqueletes_ of Milans at San Jeronimo de la Murtra, and penetrated
