All this firing, of course, put an end to surprise, and by the time that order was restored and the advance resumed, Soult and his five thousand had slipped away. After a short stay at Llerena, Graham moved on to the ground upon which had been fought the battle of Albuhera; and while there the troops heard in the distance the desperate firing which resulted in the capture of Badajoz. It will be remembered that, twice during the previous year, the fortress had been besieged and unsuccessfully assailed. On each of those occasions Wellington had directed his attack from the north, intending first to capture the detached work of St Christoval, in order to establish batteries there preparatory to an assault on the castle. For his third attempt he adopted a new plan, and decided to attack from the south, capturing the Picurina outwork, breaching the bastions opposite to it, and then delivering the assault. The trenches were pushed rapidly forward; Picurina was carried by assault on the night of the 25th March, and the breaching batteries were immediately established. For ten days they battered the walls of the fortress, until the necessary breaches were effected, when Wellington gave immediate orders for the assault to take place; and on the night of the 6th-7th April 1812 occurred one of the most bloody struggles in the annals of war--a struggle the horrors of which lived in the memories of the surviving assailants for ever afterwards. The breaches defied all attempts; time after time assaults were delivered and beaten back; and the ditch became filled with dead and wounded. Elsewhere, however, fortune favoured the assailants, the 3rd Division entering the place by the San Vincente bastion. Thus Wellington captured his second fortress in 1812, but at the cost of 5000 men out of the 21,000 engaged.
