The end of the fifteenth century saw the development of the carrack into the caravel, such a ship as the _Sancta Maria_, in which Columbus sailed to the West Indies in 1492. As her original plans were found in the dockyard at Cadiz, and a replica of the famous original was built from them by Spanish workmen in the arsenal of Carracas in 1892 for the Chicago Exhibition, which took place in the following year, we know exactly what she was like. She was just over 60 feet long on her keel, and had a length over all of 93 feet, with a beam of nearly 6 feet. She had a displacement of 233 tons when fully laden and equipped. She had three masts, but only the mainmast had a top-sail. The mizzen carried a lateen sail. She was considerably smaller than many ships of her day, but in general appearance and rig she approximated to the smaller ships of the Elizabethan epoch, and she and her class may well be considered as forming a connecting-link between the old single-masted "round ships" and the square-rigged, many-gunned line-of-battleship, which from the time of Henry VIII to Queen Victoria formed the mainstay of our battle fleets. There were, of course, many developments and improvements during this long period, but the type persisted throughout, just as did that of the modified Viking ship in mediæval ages. So much for the ships of the Middle Ages. But before we go on to take stock of their crews it will be as well to attempt some description of the way they were fought. Nowadays the ship armed with the heaviest and longest-ranged guns--if her gunners know their work--seems to be able to "knock out" a slightly less powerfully gunned opponent before she can get in any effective reply. The present war has given us many illustrations of this fact. The _Scharnhorst_--a crack gunnery ship--with her heavier broadside, was able to sink the _Good Hope_ with little or no damage to herself, and in her turn she was simply demolished by the heavy guns of the _Inflexible_ and the _Invincible_ off the Falkland Islands. But in the Middle Ages there was nothing like this. All decisive fighting was practically hand to hand and man to man, except for the use of the ram by galleys and the exchange of arrows and stones at comparatively close quarters. But victory was only achieved, as a general rule, when the enemy's ship was boarded and her crew defeated in a bloody tussle, at the end of which no one but the victors remained alive, unless, perhaps, some knight or noble who was worth preserving for the value of his ransom. The military portion of the crew, the archers, men-at-arms, and their knightly leaders, carried the usual arms of their day. The seamen, who were in the minority, probably used knives, short swords, and spears, and made themselves very useful in hurling big stones, heavy javelins called "viretons", unslaked lime, and other disagreeable missiles from the "top-castles" at the head of the mast or masts.
