At 10.30 the _Alexandra_ had one of her heavy guns dismounted and rendered unserviceable. Shortly after the _Inflexible_ weighed anchor and joined the _Sultan_, _Superb_, and _Alexandra_, and by 12.30 p.m. the combined fire of the four ships had nearly silenced all the guns in the Ras-el-Tin Forts. It should be mentioned that, in addition to helping these three vessels, the _Inflexible_ had at the same time been engaging the Mex Forts, and doing great execution with her 80-ton guns. The remaining vessel of the outside squadron, the _Temeraire_, was meanwhile supporting the attack of the inside squadron on the Mex batteries at a range of from 3,500 to 4,000 yards, and making great havoc with her guns. Unfortunately, in taking up her position, she had got too close to the shoal water of the Boghas Pass, and in swinging round had grounded on the reef. The gunboat _Condor_ promptly went to the assistance of the huge ironclad, and eventually the ship was got off without injury. Although the batteries at Ras-el-Tin had, as above stated, practically ceased firing, some heavy guns in Fort Adda still kept up a desultory cannonade. At 12.30 p.m. the _Sultan_ signalled to the _Inflexible_, whose work was now finished both at Ras-el-Tin and Mex, "Adda and Pharos are the only ones not silenced, all our filled shell are expended, and if you are going that way, one or two shells from your heavy guns would do much good, if you don't mind." At 12.35 the _Sultan_ added, "Please silence Adda as well." The _Inflexible_ then stood across to Fort Adda, and at 12.40 opened fire. Shortly after, the _Temeraire_ was signalled, "Assist _Inflexible_ in destroying Pharos and Silsileh." The _Temeraire_ then weighed and steamed over to the position indicated, and assisted in shelling both forts. About 1.30 p.m. a lucky shell from the _Superb_, whose practice was very good, blew up the magazine of Fort Adda. The explosion was terrific, and huge pieces of _débris_ were thrown into the air, whilst a dense cloud of smoke for some seconds hid the works from view. The fort at once ceased firing, and when the smoke cleared away it was seen that the garrison had retreated from the blackened ruins. As early as 1.30, the ships were beginning to run short of ammunition, and the _Sultan_ signalled to the _Alexandra_, "How many filled shell have you?" and received the answer "Twenty." At one o'clock the _Alexandra_ signalled that she had only thirty common shell left, and was answered by the _Sultan_ that she had none at all, and that the _Alexandra_ had better use common shell as the _Sultan_ was doing.
