Verdier, therefore, on the advice of his engineers, set to work to attack these points of the enceinte between La Gironella and Santa Maria. New batteries erected amid the ruins of Monjuich were levelled against them, in addition to such of the older batteries as could still be utilized. On the front by Pedret also, where nothing had hitherto been done, works were prepared for guns to be directed against Santa Maria and Santa Lucia. Meanwhile a perpetual bombardment with shell was kept up, against the whole quarter of the town that lay behind the selected points of attack. Mortars were always playing, not only from the Monjuich heights but from two batteries erected on the so-called ‘Green Mound’ in the plain beyond the river Ter. Their effect was terrible: almost every house in the northern quarter of Gerona was unroofed or destroyed: the population had to take refuge in cellars, where, after a few days, they began to die fast--all the more so that food was just beginning to run short as August advanced. From the 14th to the 30th of that month Verdier’s attack was developing itself: by its last day four breaches had been established: one, about forty feet broad, in the curtain of St. Lucia, two close together in the works at La Gironella[42], the fourth and smallest in the platform of San Cristobal. But the approaches were still far from the foot of the wall, the fire of the outlying Spanish works, especially the Calvary fort, was unsubdued, and though the guns along the attacked front had all been silenced, the French artillery had paid dearly both in lives and in material for the advantage they had gained. Moreover sickness was making dreadful ravages in the ranks of the besieging army. The malarious pestilence on which the Spaniards had relied had appeared, after a sudden and heavy rainfall had raised the Ter and Oña beyond their banks, and inundated the whole plain of Salt. By malaria, dysentery and sunstroke Verdier had lost 5,000 men, in addition to his casualties in the siege. Many of them were convalescents in the hospitals of Perpignan and Figueras, but it was hard to get them back to the front; the _somatenes_ made the roads impassable for small detachments, and the officers on the line of communication, being very short of men, were given to detaining drafts that reached them on their way to Gerona[43]. Hence Verdier, including his artillerymen and sappers, had less than 10,000 men left for the siege, and these much discouraged by its interminable length, short of officers, and sickly. This was not enough to guard a periphery of six miles, and messengers were continually slipping in or out of Gerona, between the widely scattered camps of the French. [42] Belmas, for convenience’ sake, distinguishes these two breaches by calling the northern one the breach in the Barracks, the southern the breach in the Latrines of the ‘German Redoubt.’
