In addition to the sortie of the 16th April, Sir Sidney Smith kept the besiegers constantly on the alert by landing parties from the ships' boats on the flanks of their lines of trenches. The attacks were sometimes pushed home, the earthworks were overthrown, the fascines carried off for use in the redoubts, guns spiked, and intrenching tools captured, and these attacks greatly added to the labour imposed upon the besiegers, who were compelled not only to keep strong bodies in the advanced trenches but to defend the whole line of attack against flank surprises by their enterprising foes.
The Turks vied with the British in activity, making frequent night attacks on the trenches, and generally succeeding in carrying off a number of fascines, which were greatly needed, and were of special utility in the construction of the ravelin. The day after the repulse of the fourth attack the garrison suffered a heavy loss in the death of Colonel Phelypeaux, who died of fever brought on by want of rest and exposure to the sun. On the same day another, and almost as serious a loss, was sustained, for Captain Wilmot was killed by a musket shot while in the act of mounting a gun in the breach.
The midshipmen had, two days before, lost one of their comrades named Morris, who, with three seamen, was killed in one of the sorties, eight other blue-jackets of the Tigre being wounded at the same time. On the night of the 2nd of May the enemy made two desperate attempts to capture the English ravelins, but the marines in charge, aided by the fire from the walls and ships, held their ground, and repulsed the French with much loss. Every day the fighting increased in fury. Between the 1st and 9th the French made no less than five attacks upon the breach; these were all beaten off with very heavy loss; while the defenders, on their part, made frequent sorties to compel the assailants to stand on the defensive, and to interfere with their attempts to carry the approaches up to the foot of the walls.
The fire of the vessels was still maintained, but the besiegers had so raised and strengthened the earthworks protecting their traverses and trenches that they were now able to go backwards and forwards to the front with but little danger from the ships' fire.
Edgar had now lost the companionship both of Condor and Wilkinson. These had both gone back to their ship, for the death of Morris and the wounding of Forbes and Lieutenant Knight had left the ship short of officers. Condor acted as junior lieutenant until the latter was fit for service again, and both he and Wilkinson took part in the boat attacks and the sorties from the town. Edgar was therefore now in command of the blue-jackets on shore, who were held always in readiness to run to the aid of the garrison at any spot where there might be sudden danger.
It was believed that the French were again mining in several places, and although Colonel Douglas, who had succeeded Phelypeaux in command of the engineering operations, set parties at work to drive countermines, the work progressed slowly, and it was difficult to ascertain the precise direction in which the enemy were driving their galleries. Edgar still acted as interpreter to Sir Sidney Smith, and was the bearer of his orders to the Turkish officers. He was very glad that it was but seldom that he was called upon to accompany his chief in his visits to the tower, for the stench here from the unburied bodies of the French and of the Turks overwhelmed by the explosion was overpowering. Numbers of the Turks stationed here were attacked by mortal illness, others became delirious, and it was necessary to change the force holding it at very frequent intervals.
On the evening of the 7th of May there was immense satisfaction in the town, as a number of sail were seen on the horizon. It was certain that this was the force under Hassan Bey, which had been originally intended for Egypt, but had been diverted from its course by Sir Sidney Smith's orders. Its arrival had been anxiously looked for during the last month, but it had been detained by calms and other causes at Rhodes, and it was only a portion of the force that now, on the fifty-first day of the siege, made its appearance.
From the enemy's camp on the hills the fleet was made out as soon as from the town, and the effect was in a very short time apparent by the fire of the enemy's batteries being redoubled, and it was apparent that Bonaparte had determined to make a great effort to capture the town before the arrival of the reinforcements; and in a short time a great column was seen advancing to the attack.
Two of the Tigre's 68-pounders, mounted on native craft lying in the little port near the water-gate, opened upon them with shells, while two guns, manned by British sailors, one on the castle of the lighthouse, the other on one of the ravelins, poured grape into them. But the column moved on. The tremendous cannonade from their batteries overpowered that from the guns on the walls, and they suffered but little from the fire from the ravelins, as they had, the night before, constructed two breastworks from the end of their trenches to the breach, the materials used being sandbags and the bodies of their own slain.
In spite of the efforts of the defenders the French effected a lodgment in the tower. Its upper story had now been entirely destroyed by the enemy's fire, and the fragments had so increased the heap at the foot of the breach that the assailants were able to mount without the use of ladders. This was the most critical moment in the siege.
