This first duel between ironclad vessels attracted an enormous amount of attention, as is only to be supposed. The net result in this country was that Captain Cowper Coles, R.N., was allowed to have a cupola- or turret-ship built which he had designed some years before. The _Royal Sovereign_, a wooden three-decker, was cut down to within a few feet of the water-line, plated with 5-1/2-inch iron, and fitted with four turrets. The foremost one carried two guns, the remainder one apiece. She had very light pole masts and light, hinged iron bulwarks, which gave her 3-1/3 feet more freeboard at sea but had to be lowered before she could fight her guns. Captain Coles, however, had the usual hankering after "masts and yards", and, the _Royal Sovereign_ having proved moderately successful, induced the Admiralty to build a fully rigged turret-ship. This was the unfortunate _Captain_, whose low freeboard, heavy turrets, superstructures, and fully-rigged tripod masts caused her to turn turtle in a squall off Cape Finisterre on the night of 6th September, 1870. Her inventor went down in her. Her gunner and seventeen men were the sole survivors. One other full-rigged turret-ship was built--the _Monarch_. As she had a very considerable freeboard she proved a seaworthy ship, but she was the last of her kind.[42] In the meantime several small coast-defence turret-vessels had been built, such as the _Scorpion_ and _Wyvern_ in 1865, the _Abyssinia_, _Magdala_, and _Cerberus_ in 1870, and the _Glatton_, _Gorgon_, _Cyclops_, and others a year or so later. They had one or two masts, but were not rigged ships. These little turret-ships developed into the battleships _Devastation_, _Dreadnought_, and _Thunderer_, launched between 1873 and 1877. Each had two turrets containing a couple of heavy guns apiece. Their hulls were heavily armoured, and they had but one mast fitted with a military top for machine-guns. It is from this branch of our earlier armour-clad construction that our modern "Dreadnoughts" derive their descent rather than from the broadside type.
