[24] This last was done by public subscription, when the engineers pointed out the danger of the city being stormed across the river-bed. See Arteche, vii. 151. Belmas and Vacani do not seem to have known of this fact, as each of them makes the remark that if the Mercadal had been taken, a sudden rush might have taken the assailants across the shallow river and into the old town. It may be remarked that there had once been a river-wall, but that most of it had been allowed to fall into decay when the Mercadal was taken into the city defences. All these precautions must be put to the credit of the governor, Mariano Alvarez de Castro, a man to be mentioned with all honour and respect, and probably the best soldier that Spain produced during the whole Peninsular War. He was a veteran of the Revolutionary and Portuguese wars, and had a good reputation, but no special credit for military science, down to the moment when he was put to the test. He had been the officer in charge of the castle of Barcelona on the occasion when it was seized by Duhesme in March 1808: his spirit had been deeply wounded by that vile piece of treachery, and he had at once adhered to the national cause. Since then he had been serving in the Ampurdam against Reille, till the moment when he was appointed governor of Gerona. Alvarez is described by those who served under him as a severe, taciturn man of a puritan cast of mind. ‘I should call him,’ wrote one of his brigadiers, ‘an officer without the true military talents, but with an extreme confidence in Providence--almost, one might say, a believer in miracles. His soul was great, capable of every sacrifice, full of admirable constancy; but I must confess that his heroism always seemed to me that of a Christian martyr rather than of a professional soldier[25].’ General Fournas, who wrote this somewhat depreciatory sketch of his chief, was one of those who signed the capitulation while Alvarez was moaning _no quiero rendirme_ on his sick-bed, so that his judgement is hardly to be taken as unprejudiced; but his words point the impression which the governor left on his subordinates. The details of his defence sufficiently show that he was a skilful and resourceful as well as an obstinate general. His minute care to utilize every possible means of defence prove that he was no mere waiter on miracles. That he was a very devout practising Catholic is evident from some of his doings; at the opening of the siege a great religious ceremony was held, at which the local patron saint, Narcissus, was declared captain of the city and presented with a gold-hilted sword. The levy _en masse_ of the citizens was called ‘the Crusade,’ and their badge was the red cross. The ideas of religion and patriotism were so closely intertwined that to the lay companies of this force were afterwards added two clerical companies, one composed of monks and friars, the other of secular priests: about
