In February 1700 Dampier called at Juan Fernandez and while there Captain Straddling of the "Cinque Porte" galley quarrelled with his men, forty-two of whom deserted but were afterwards taken on board by Dampier; five seamen, however, remained on shore.
In October 1704 the "Cinque Porte" returned and found two of these men, the others having been apparently captured by the French.
The incorporation of the Cinque Ports had its origin in the necessity for some means of defence along the southern seaboard of England, and in the lack of any regular navy.
The highest office in connexion with the Cinque Ports is that of the lord warden, who also acts as governor of Dover Castle, and has a maritime jurisdiction (vide infra) as admiral of the ports.
The court of admiralty for the Cinque Ports exercises a co-ordinate but not exclusive admiralty jurisdiction over persons and things found within the territory of the Cinque Ports.
