much closer. Hence shell entering the battery of the latter would have taken much greater effect.
It is not my intention to detail at length the changes made in successive designs after the 'Warrior.' Already rifled ordnance was imposing a fresh advance, and the struggle between guns and armour had begun. The 'Warrior' had one sister, the 'Black Prince'; and that the second-class battle ship, corresponding to the two-decker, should be represented under the new order, two smaller armour-clads, the 'Defence' and 'Resistance,' were begun. The disposition of their armour was similar to that of the 'Warrior,' but they were only 280 ft. long, and the displacement 6150 tons. The 'Hector' and ’Valiant' were two other ships of the same type, with slight modifications. In the next designs it was determined to remedy the defect already alluded to, namely, the unprotected ends. This was first done in the 'Achilles.' Her length was the same as that of the 'Warrior,' but she was 600 tons larger, to allow of the armour being carried completely to the ends. This ship may be considered the first example of the armoured belt, with gun battery in the centre, though this battery before long became even more contracted.
We come now to three more ships of the 'Warrior' type, the 'Minotaur,' 'Northumberland,' and 'Agincourt.' To have the advantages of their model, without the defects, the length was increased to 400 ft, and the armour taken completely round. Its thickness was increased to 5½ in., but secured to only 9 in. of wood
