This was the invasion which resulted in the victory of Agincourt and the capture of Harfleur. In the year following (1416) France was again invaded and the fleet was stated by some to have numbered 300, and by others 400 ships. A naval battle was fought off Harfleur. It resulted in a complete victory for Henry. The old tactics and the old weapons seem to have been used. Although, as we have seen, guns had been used in sea-fights nearly forty years previously, there is no mention of their having been employed on either side at this battle.

In 1417 the king again collected 1,500 vessels at Southampton for a fresh invasion of France. Having first obtained the command of the sea by a naval victory over the French and Genoese, a landing was duly effected near Harfleur. Several vessels, including four large carracks, were captured in the sea-fight, and were added to the king's navy.

During the reign of Henry V. the Mercantile Marine of England made no progress. Commerce was checked in consequence of the state of war which prevailed, and the improvements in shipbuilding seem to have been confined to the Royal Navy. It seems probable, however, that the experience gained in the construction and navigation of the very large ships which the king added to the navy had its effect, ultimately, in improving the type of merchant-vessels.

During the forty years of the reign of Henry VI. England was so greatly exhausted and impoverished by war with France and by internal dissensions at home, that commerce and shipbuilding made little progress. We possess a sketch of a ship of the early part of the reign of Henry VI. It is contained in a manuscript in the Harleian Library of the date, probably, of 1430 to 1435. It is reproduced in Fig. [36], and differs from the ship of the reign of Richard II. shown in Fig. [35], chiefly in having the poop and forecastle more strongly developed.

While England was steadily declining in power from the time of the death of Henry V., a new maritime nation was arising in South-Western Europe, whose discoveries were destined to have a most marked effect on the seaborne commerce, and consequently on the shipbuilding of the world. In the year 1417 the Portuguese, under the guidance of Prince Henry the Navigator, commenced their exploration of the west coast of Africa, and they continued it with persistency during the century. In 1418 they discovered, or rather re-discovered, the island of Madeira, for it is extremely probable that it was first visited by an Englishman of the name of Machin.

The Portuguese prince firmly believed that a route could be opened round Africa to the Indies. To reach these regions by sea seems to have been the goal of the great explorers of the fifteenth century, and the Portuguese were stimulated in their endeavours by a grant from Pope Martin V. of all territories which might thenceforward be discovered between Cape Bojador and the East Indies. In 1446 an expedition consisting of six caravels was fitted out, and made a voyage to Guinea; it resulted in the discovery of the Cape Verde Islands. The caravel was a type of ship much used by the countries of Southern Europe in the fifteenth and sixteenth centuries. A description of a Spanish vessel of this type is given on pages 87 to 89. In 1449 the Azores were discovered. In 1481 a lucrative trade was opened up between Portugal and the natives of Guinea. Six years afterwards the Cape of Good Hope was reached by Bartholomew Diaz, and in 1497 it was doubled by Vasco da Gama.

During a great part of the period in which the Portuguese were thus occupied in extending their commerce and in paving the way for great discoveries, the condition of England, owing to the French war and to the subsequent Wars of the Roses, was passing from bad to worse. Nevertheless, the spirit of commercial enterprise was not wholly extinguished. A few merchants seem to have made fortunes in the shipping trade, and among them may be mentioned the famous William Canynge of Bristol, who was probably the greatest private shipowner in England at the end of the reign of Henry VI. and during the time of Edward IV. (1461 to 1483). Canynge traded to Iceland, Finland, and the Mediterranean. He is said to have possessed ships as large as 900 tons, and it is recorded on his monument, in the church of St. Mary Redcliffe, in Bristol, that he at one time lent ships, to the extent of 2,670 tons, to Edward IV. It is also related of him that he owned ten ships and employed 800 sailors and 100 artisans.
