they were collecting means and materials for a siege, the difficulties of which they had been taught how to estimate. The works were directed by the Commander of the Engineers, Colonel San Genis; and what was defective in them was imputable not to any want of science, but to the difficulty of fortifying the whole circuit of a great city. The Aljafaria, which had been the palace of the Moorish kings, then of the kings of Aragon, and was now called the Castle of the Inquisition, because it contained the prisons of that accursed tribunal, had been converted into a fortress by Philip V., and was now repaired and strengthened. It was a square, with four tower-bastions, surrounded by a good ditch, and communicating with the city by a double caponiere. From thence to the bridge over the Guerva the place was protected by a long line of wall and batteries; two Capuchin convents which came into the line were fortified, and served to flank it. A ditch was carried from one of these to the bridge, and the bridge itself secured by a _tête-de-pont_. A double retrenchment extended from thence to the memorable Convent of St. Engracia, which was made a sort of citadel; and from that Convent to the Ebro the old wall had been strengthened; this part of the city being covered also by the bed of the Guerva, and by the Convent of St. Joseph on the farther bank of that river, which had been well fortified, and was the most salient point of the whole circle, serving as a strong _tête-de-pont_ to protect the besieged when they sallied in the direction of Valencia. The suburb beyond the Ebro was defended by redoubts and fleches, with batteries and traverses at the entrance of the streets. The artillery amounted to 160 pieces, the greater part being four, eight, and twelve pounders: what pieces there were of larger calibre had mostly been recovered from the canal into which the French had thrown them on their retreat. Great part of the cannon balls also were what the French had fired or left behind them. To prevent all danger from the explosion of their magazines, it was determined not to prepare a stock of gunpowder, but to make it day by day as it should be wanted; and this could easily be done, because Zaragoza was the place where all the saltpetre of Aragon was refined. There was no want of musquets, either for the inhabitants or the troops and peasantry with whom the city was crowded. The stores contained corn, wine, brandy, oil, salt-fish, and pulse, sufficient for six months’ ♦CAVALLERO, 74–80.

Palafox would have had the central army, as well as his own troops, take refuge there after the battle of Tudela. Castaños indeed led away the wreck of that army in
