These successes were bought at the moderate loss of 350 men, of whom two-thirds fell in the fighting on the Santa Engracia front; the Spaniards lost somewhat more, including a few prisoners. In any ordinary siege the day would have settled the fate of the place, for the besiegers had broken through the _enceinte_ in two places, and though the space seized inside the Palafox battery was not large, yet on each side of Santa Engracia the assailants had penetrated so far that a quarter of a mile of the walls was in their possession. But Saragossa was not as other places, and the garrison were perfectly prepared with a new front of defence, composed of batteries and crenellated houses in rear of the lost positions. Two wedges, one large and one small, had been driven into the town, but they had to be broadened and driven further in if they were to have any effect. On the twenty-eighth, therefore, a new stage of the siege began, and the street-fighting, which was to last for twenty-four days more, had its commencement. Lannes had heard, from those who had served under Verdier in the first siege, of the deplorable slaughter and repeated repulses that had followed the attempt to carry by main force the internal defences of the city. To hurl solid columns of stormers at the barricades and the crenellated houses was not his intention. He had made up his mind to advance by sap and mine, as if he were dealing with regular fortifications. His plan was to use each block of houses that he gained as a base for the attack upon the next, and never to send in the infantry with the bayonet till he had breached by artillery, or by mines, the building against which the assault was directed. This form of attack was bound to be slow, but it had the great merit of costing comparatively little in the way of casualties. The fact was that the Marshal had not the numbers which would justify him in wasting lives by assaults which might or might not be successful, but which were certain to prove very bloody. The whole Third Corps, as we have already seen, did not now furnish much more than 13,000 bayonets, while Gazan’s men were all occupied in watching the suburb, and Suchet’s lay far out, as a covering corps set to watch Perena and Lazan. There was no one single dominating position in the city whose occupation was likely to constrain the besieged to surrender. The whole town is built on a level, and its fifty-three solidly-built churches and convents formed so many forts, each of which was defensible in itself and could not be reduced save by a direct attack. All that could be done was to endeavour to capture them one by one, in the hope that at last the Saragossans would grow tired of their hopeless resistance, and consent to surrender, when they realized that things had gone so far that they could only protract, but could not finally beat off, the slow advance of the besieging army.
