That day was spent in getting the guns into position and in a further reconnaissance, while two ships bombarded the Mortella redoubt, though without breaching it. The ships, moreover, were set on fire by the enemy's hot shot, and were forced to sheer off, with a loss of some sixty men. On the next day more guns were mounted on land, but although they did little damage to the solid tower, their fire made it impossible for the enemy to show himself or reply, and the French officer in command, seeing that he could no nothing, surrendered. The next outwork to be disposed of was the Convention redoubt, and this gave a good deal of trouble. Moore, who was still conducting operations on land, inspected the ground with General Dundas and Major Koehler, and discovered an excellent artillery position, from which it would be possible to batter the Convention. The difficulty was to get the guns up the steep, rocky hill, but, with the aid of a party of seamen with tackle, two 18-pounders and a howitzer were mounted within the next few days, and a mortar and some other guns were placed on a more accessible position, when the enemy's redoubt was subjected to a heavy cannonade for two days. Moore had now with him only the 51st, but on the 17th February the General gave him orders for the assault that night. The Royals were to join the 51st, and Moore was to assail the front of the redoubt, while the other British regiments and the Corsicans were to deliver simultaneous assaults on either flank. Moore decided to attack in column of companies, the first company consisting of the grenadiers and light infantry[17] of the Royals, the second of the grenadiers of the 51st, the third of the light company of the 51st, then the battalion of the Royals (only sufficient to make five companies), then three companies of the 51st. The other five companies of the 51st followed in rear as a support; and in rear again came 130 sailors, under Captain Cooke, with entrenching tools.
