Mining through the houses was not sufficient. The greater streets divided the city into a number of small districts, the group of dwellings in each of which forming a separate stronghold. To cross these streets it was necessary to construct underground galleries, or build traverses, since a Spanish battery raked each street, and each house had to be fought for and taken separately.
While the Spaniards held the convents and churches the capture of the houses by the French was of little service to them, the defenders making sudden and successful sallies from these strong buildings, and countermining their enemies, their numbers and perseverance often frustrating the superior skill of the French. The latter, therefore, directed their attacks upon these buildings, mining and destroying many of them. On the other hand, the defenders saturated with rosin and pitch the timbers of the buildings they could no longer hold, and interposed a barrier of fire between themselves and their assailants which often delayed them for several days.
Step by step, inch by inch, the French made their way forward, complete destruction alone enabling them to advance. The fighting was incessant. The explosion of mines, the crash of falling buildings, the roar of cannon and musketry, the shouts of the combatants continually filled the air, while a cloud of smoke and dust hung constantly over the city as the terrible scene of warfare continued day after day.
By the 17th of February the Cosso was reached and passed. But the French soldiers had become deeply discouraged by their fifty days of unremitting labor and battle, fighting above and beneath the earth, facing an enemy as bold as themselves and much more numerous, and with half the city still to be conquered. Only the obstinate determination of Marshal Lannes kept them to their work.
By his orders a general assault was made on the 18th. Under the university, a large building in the Cosso, mines containing three thousand pounds of powder were exploded, the walls falling with a terrific crash. Meanwhile, fifty pieces of artillery were playing on the side of the Ebro, where the great convent of St. Lazar was breached and taken, two thousand men being here cut off from the city. On the 19th other mines were exploded, and on the 20th six great mines under the Cosso, loaded with thousands of pounds of powder, whose explosion would have caused immense destruction, were ready for the match, when an offer to surrender brought the terrible struggle to an end.
The case had become one of surrender or death. The bombardment, incessant since the 10th of January, had forced the women and children into the vaults, which were abundant in Saragossa. There the closeness of the air, the constant burning of oil, and the general unsanitary conditions had given rise to a pestilence which threatened to carry off all the inhabitants of the city. Such was the state of the atmosphere that slight wounds became fatal, and many of the defenders of the barricades were fit only[pg 311] for the hospitals. By the 1st of February the death-rate had become enormous. The daily deaths numbered nearly five hundred, and thousands of corpses, which it was impossible to bury, lay in the streets and houses, and in heaps at the doors of the churches, infecting the air with their decay. The French held the suburbs, most of the wall, and one-fourth of the houses, while the bursting of thousands of shells and the explosion of nearly fifty thousand pounds of gunpowder in mines had shaken the city to its foundations. Of the hundred thousand people who had gathered within its walls, more than fifty thousand were dead; thousands of others would soon follow them to the grave; Palafox, their indomitable chief, was sick unto death. Yet despite this there was a strong and energetic party who wished to protract the siege, and the deputies appointed to arrange terms of surrender were in peril of their lives.
The terms granted were that the garrison should march out with the honors of war, to be taken as prisoners to France; the peasants should be sent to their homes; the rights of property and exercise of religion should be guaranteed.
Thus ended one of the most remarkable sieges on record,—remarkable alike for the energy and persistence of the attack and the courage and obstinacy of the defence. Never in all history has any other city stood out so long after its walls had fallen. Rarely has any city been so adapted to a protracted defence. Had not its houses been nearly incombustible it would have been reduced to ashes by the bombardment. Had not its churches and convents[pg 312] possessed the strength of forts it must have quickly yielded. Had not the people been animated by an extraordinary enthusiasm, in which women did the work of men, a host of peasants and citizens could not so long have endured the terrors of assault on the one hand and of pestilence on the other. In the words of General Napier, the historian of the Peninsular War, "When the other events of the Spanish war shall be lost in the obscurity of time, or only traced by disconnected fragments, the story of Zaragoza, like some ancient triumphal pillar standing amidst ruins, will tell a tale of past glory."
