At this point—June 2—Dragut arrived with his galleys and expressed nothing but disapproval for the Turkish operations. He pointed out that the besiegers should have isolated the fortifications from the rest of the island before proceeding to attack St. Elmo; but, as the siege had started, he insisted on continuing it as vigorously as possible. He erected a powerful battery on the summit of Mount Sceberras, which swept both Fort St. Angelo and Fort St. Elmo, and erected another on the headland opposite St. Elmo on the other side of the Marsa Muscetto, which was henceforth known as Point Dragut.
As soon as this was done the bombardment restarted with relentless fury. The Knights made a sortie to destroy some of the Turkish guns, but were driven back, and the Turks then captured and held a covered way leading up to a ravelin; a few days later, taking advantage of the negligence of the garrison, they surprised the ravelin itself, and, but for the efforts of a Spanish officer, would have captured the fort. After desperate fighting the Knights were still holding the fort, but had been unable to recapture the ravelin. The next day another attack was made by Mustapha, but without avail; the ravelin remained in Turkish hands, but it had cost them 2,000 men.
It was a great gain, however; two guns were mounted on it, and all the Turkish artillery, including that of the galleys, began to play on the hapless fort. It was no question of a breach; the walls were gradually destroyed till there was nothing left of the enceinte but a mass of ruins. Every part of the fort was directly exposed to the fire of the two guns on the ravelin, and this exposure made the strain on the Knights intolerable.
The garrison sent a Knight, renowned for his bravery, to report these conditions to the Grand Master and to ask for permission to withdraw. La Valette, feeling it imperative that the fort should hold out to the last minute, sent him back with orders that it was to be defended to the end. The garrison, amazed by his reply, sent a prayer for relief, failing which they would sally forth, sword in hand, to meet their death in open fight rather than be buried like dogs beneath the ruins. The Grand Master received the request with the stern comment that, not only were their lives at the disposal of the Order, but the time and manner of their death; but to make sure that their complaints were justified he would send three Knights to investigate the condition of the fort. One of the three (probably in collusion with La Valette) maintained the fort could be held, and offered himself to hold it with volunteers, who were immediately forthcoming in large numbers; but when the message arrived at St. Elmo announcing that the garrison was to be relieved, there was consternation among the defenders, who, now realising the ignominy of their prayer, sent out yet another request to St. Angelo, this time to be allowed to hold St. Elmo to the death. After some delay the Grand Master granted the permission.
This was June 14; on the 16th the Ottomans delivered a grand assault. The fort was attacked on three sides, from Mount Sceberras and on each flank. The guns of St. Angelo rendered great service all day by raking the attacking forces in enfilade, and especially by breaking up the flank attack from the side of the Grand Harbour. All day long the battle went on with unabating fury; time after time the Janissaries burst over the ruined walls, and each time they were repulsed. Attacked on all sides, the few defenders fought with dauntless heroism, and when the night fell the Maltese Cross still waved over the fort.
Reinforcements were dispatched as soon as night set in, and the volunteers far exceeded all requirements.
Now at last the Turkish commanders perceived that, to capture St. Elmo, it must be isolated from St. Angelo. In the course of the next few days a battery was constructed on the promontory at the entrance of the Grand Harbour where Fort Ricasoli stood in later times, and another was mounted on the side of Mount Sceberras to sweep the landing place beneath the fort. Both batteries cost many Turkish lives, but their construction and the extension of the investing trenches to the Grand Harbour meant the complete isolation of St. Elmo. The Turks sustained their greatest loss when Dragut, while superintending the works, received a wound from which a week later he died.
For three days twenty-six guns kept up the bombardment, and on the early morning of June 22 another grand assault was made. Three times repulsed and three times renewed, the attack failed in the end, and the handful of surviving Knights was left at nightfall in possession of their ruins. All attempts during the night to send reinforcements failed under the fire of Dragut's new batteries, and La Valette saw that his men were beyond all hope of rescue.
The sixty shattered survivors prepared for death; worn out, they betook themselves at midnight to their little chapel, where they confessed and received the Eucharist for the last time. Dawn found them waiting, even to the wounded, who had been placed in chairs sword in hand to receive the last onslaught. Incredible as it may appear, the first assault was driven back, but the attack finally broke up the defence, and, with the exception of a few Maltese who escaped by swimming, the garrison perished to a man.
June 24, St. John the Baptist's Day, was one of sorrow inside the beleaguered fortress. The Turks had soiled their victory by mutilating their dead foes and throwing them into the Grand Harbour; La Valette took reprisals, and from that time neither side thought of quarter.
