The left attack of the French, that from the Santa Engracia side, made much more progress, though even here it was slow and dearly bought. On February 10, however, in spite of several checks, the besiegers for the first time forced their way as far as the Coso, working through the ruined hospital which had been destroyed in the first siege. On the same day, at the north-western angle of their advance, they made a valuable conquest in the church and convent of San Francisco. A mine was driven under this great building from the ruins of the hospital, and filled with no less than 3,000 pounds of powder. It had not been discovered by the Spaniards, and the convent was full of fighting-men at the moment of the explosion. The whole grenadier company of the 1st regiment of Valencia and 300 irregulars were blown up, and perished to a man[143]. Nor was this all: in the northern part of the building was established the main factory for military equipment of the Army of Aragon: it was crammed with workpeople, largely women, for Palafox had forgotten or refused to withdraw the dépôt to a less convenient and spacious but more safe position. All these unfortunate non-combatants, to the number of at least 400, perished, and the roof-tops for hundreds of yards around were strewn with their dismembered limbs. [143] In Lejeune, i. 169, the reader will find some horrible anecdotes of this explosion. It might have been expected that, as the immediate consequence of this awful catastrophe, the French would have made a long step forward in this direction. But such was not the case: before the smoke had cleared away Spaniards rushed forward from the inner defences, and occupied part of the ruins of San Francisco. A body of peasants, headed by the _émigré_ colonel de Fleury, got into the bell-tower of the convent, which had not fallen with the rest, and kept up from its leads a vigorous plunging fire upon the besiegers, when they stole forward to burrow into the mass of débris. But with the loss of some thirty men the French succeeded in mastering two-thirds of the ruins: next day they cleared the rest, and stormed the belfry, where de Fleury and his men were all bayonetted after a desperate fight on the winding stairs. It was first from the commanding height of this steeple that the French officers obtained a full view of the city. The sight was encouraging to them: they could realize how much the inner parts of the place had suffered from the bombardment, and noted with their telescopes the small number of defenders visible behind the further barricades, the heaps of corpses in the streets, and the slow and dejected pace of the few passengers visible. Two great gallows with corpses hanging from them especially attracted the eyes of the onlookers[144]. Other circumstances united on this and the following day (February 11-12) to show that the defence was at last beginning to slacken. A great mob of peasants,
