After this second successful sortie, no further attempt was made to push the works between the outer and second line: a third breach was effected with the view of making a flank attack at the moment of assaulting the second line in front; but when it was made, it could not be stormed for want of musket ammunition. The enemy attempted to repair it during the night, but were several times driven in. A small supply of powder having now been received from Santander, the howitzers were put in battery; but the 24-pound shot were nearly expended, and for the 18-pounders the 16-pound shot fired by the enemy were collected and made to serve: when the embrazures were opened, the guns could not be run in on account of the weather, and one of the batteries was silenced in half an hour by the enemy’s fire. By the 18th, a sufficient opening had been made in an exposed part of the second line; and the church of St. Roman, which was near the second line, had been mined. The ♦THE SECOND LINE ASSAULTED WITH ILL SUCCESS.♦ assault was made by daylight; the works were immediately carried with very little loss, and some of the German legion escaladed the third line; but they were few, and were presently driven back, for the course of the siege had taken confidence from the besiegers and given it to the besieged; and when the guards gained the parapet, the garrison rallied on the _terre plein_ of the work, and assembled in force, then advanced, and drove the assailants back completely from the line. The mine under the church did little injury to it; but it so alarmed the enemy, that they exploded their own mines, which destroyed the greater part: the troops lodged themselves in the ruins, and a communication was carried to this point during the night. A convoy of heavy artillery and ammunition was now on its way from Santander, and the castle might then have been reduced in a few days, without further loss; but it was now too late, and after that failure all circumstances induced Lord Wellington to think only of retreat. ♦MOVEMENTS OF THE FRENCH IN THE NORTH.♦
