Blake responded by a second effort, less happily planned than that of September 1. He called together his scattered divisions, now about 12,000 strong, and secretly concentrated them at La Bispal, between Gerona and the sea. He had again got together some 1,200 mules laden with foodstuffs, and a large drove of sheep and oxen. Henry O’Donnell, an officer of the Ultonia regiment, who had been sent out by Alvarez, marched at the head of the convoy with 2,000 picked men; a division of 4,000 men under General Wimpfen followed close behind to cover its rear. Blake, with the rest, remained at La Bispal: he committed the egregious fault of omitting to threaten other parts of the line of investment, so as to draw off St. Cyr’s attention from the crucial point. He trusted to secrecy and sudden action, having succeeded in concentrating his army without being discovered by the French, who thought him still far away beyond Hostalrich. Thus it came to pass that though O’Donnell struck sharply in, defeated an Italian regiment near Castellar, and another three miles further on, and reached the Constable fort with the head of the convoy, yet the rest of Pino’s division and part of Souham’s concentrated upon his flank and rear, because they were not drawn off by alarms in other quarters. They broke in between O’Donnell and his supports, captured all the convoy save 170 mules, and destroyed the leading regiment of Wimpfen’s column, shooting also, according to the Spanish reports, many scores of the unarmed peasants who were driving the beasts of burden[54]. About 700 of Wimpfen’s men were taken prisoners, about 1,300 killed or wounded, for little quarter was given. The remnant recoiled upon Blake, who fell back to Hostalrich next day, September 27, without offering to fight. The amount of food which reached the garrison was trifling, and Alvarez declared that he had no need for the additional mouths of O’Donnell’s four battalions, and refused to admit them into the city. They lay encamped under the Capuchin fort for some days, waiting for an opportunity to escape. [54] See Toreno, ii, and Arteche, vii. 412.
