The three first-mentioned vessels, supported by the fire from the after turret of the _Inflexible_, which was anchored off the Corvette Pass, were directed to destroy the batteries on the Ras-el-Tin peninsula, and then to move to the eastward and attack Forts Pharos and Silsileh. The _Invincible_, _Monarch_, and _Penelope_, aided by the fire from the _Inflexible's_ forward turret and by the _Temeraire_, which took up a position off the Boghas Pass, were ordered to open fire on the guns in the Mex Lines. The gun-vessels and gunboats were directed to remain outside until a favourable opportunity should offer for moving in to the attack on Mex. At 7 a.m. the Admiral, whose flag was flying from the _Invincible_, signalled to the _Alexandra_ to fire a shell into the recently armed works on Ras-el-Tin, known as the Hospital Battery, and followed this by a general signal to the fleet, "Attack the enemy's batteries." Upon this immediate action began between all the ships, in the positions assigned to them, and the whole of the forts commanding the entrance to the harbour. A steady cannonade was maintained both by the attacking and defending forces, and for the next few hours the roar of the guns and the shrieks of passing shot and shell were alone audible. The spectacle as seen from the offing was imposing in the extreme. On the one side were the most powerful ships of modern times, all in fighting trim, with upper masts and yards struck, some slowly steaming ahead, others at anchor, but all pouring deadly broadsides into the Egyptian batteries. On the other were the forts, standing out bright and clear in the sunshine, vomiting forth volleys of fire and smoke in the direction of the attacking squadron. The weather was fine and the sea smooth, both of which circumstances were to the advantage of the attacking force. On the other hand, the wind and sun were in the enemy's favour, and the smoke, which rose like a thick wall, at times prevented those on board the ships seeing the result of their fire. At 9.40 the _Sultan_, _Superb_, and _Alexandra_, of the outside squadron, which had previously been under way and turning in succession at a range of about 1,500 yards, came to an anchor off the Lighthouse Fort. The batteries had proved stronger than had been anticipated, and the Egyptian gunners were making very good practice. The firing of the ships at the same time was less effective than could be wished. Under these circumstances, and to obtain the exact range, the three ships adopted a stationary position, and from this moment their fire steadily improved. A little after 10 o'clock the harem buildings of Ras-el-Tin Palace were set on fire and partly destroyed by a shell.
