On the 10th the fourth division, and on the 11th the third, carried on the works, but were nightly disturbed, not only by the heavy fire from the bastions, but from some guns which the French had mounted on the convent of San Francisco in the suburb on the left. Little was effected in the next two days, for the frost hardened the ground and impeded the work. On the night of the 13th the Santa Cruz convent was carried and the trenches pushed forward, and on the next afternoon the breaching batteries opened fire with twenty-five guns upon the points of the wall at which it had been determined to make the breaches, while two cannons kept down the fire of the French guns at the convent of San Francisco. The French replied with more than fifty pieces, and all night the tremendous fire was kept up on both sides without intermission. Just at daybreak the sound of musketry mingled with the roar of cannon, as the 40th Regiment attacked and carried the convent of San Francisco. Through the 16th, 17th, and 18th the artillery duel continued, some times one side, sometimes the other obtaining the advantage; but during each night the trenches of the besiegers were pushed forward, and each day saw the breaches in the ramparts grow larger and larger. On the 19th the breaches were reported as practicable--that is, that it would be possible for men to scramble up the fallen rubbish to the top, and orders were therefore given for the assault for that night. The attack was to be made at four points simultaneously; the 5th, 94th, and 77th were to attack from the convent of Santa Cruz, to make for the ditch, enter it, and work their way along to the great breach; Mackinnon's brigade of the third division was to attack the great breach from the front; the light division posted behind the convent of San Francisco were to attack from the left, and make their way to the small breach; while a false attack, to be converted into a real one if the resistance was slight, was to be made by Pack's Portuguese at the St. Jago gate at the opposite side of the town. As night fell the troops moved into their position, and Lord Wellington went to the convent of San Francisco, from whose roof he could survey the operations. The Scudamores, with the rest of the staff, took up their places behind him. Suddenly there was a shout on the far right, followed by a sound of confused cheering and firing, while flashes of flame leapt out along the walls, and the guns of the place opened fire with a crash. Now the 5th, 94th, and 77th rushed with great swiftness along the ditch, when, at the foot of the great breach, they were met by the third division. Together they poured up the breach, and the roar of musketry was tremendous. Once at the top of the breach, however, they made no progress. From a trench which had been cut beyond it, a ring of fire broke out, while muskets flashed from every window in the houses near. It was evident that some serious obstacle
