In the spring of 1610 James’s proclamation was again taken into consideration by the States of Holland and the States-General, and it was resolved to send an embassy to London, primarily to thank the king for his friendly offices in connection with the conclusion of the truce with Spain, but in reality to deal with the fishery question and some other matters. One of the ambassadors was Joachimi, who afterwards represented the States at the English Court for over twenty-five years. Another was Elias van Oldenbarnevelt, a brother of the great statesman who was then at the head of affairs in the Netherlands, and to him the business of the fishing was specially committed. They arrived in England on 14th April, and had an audience with the king a few days later and another with the Privy Council. They asked for an assurance that the king’s proclamation was not meant to extend to the United Provinces, since he was in alliance with them, and treaties existed between the two countries. But the Earl of Salisbury plainly told them that the principal motive of the proclamation arose from the multitude and disorder of their fishermen, “who had wholly drawn the fishing to themselves, to the destruction of his Majesty’s people and coast-towns”; and they were invited to further conference.[291] On the 6th May, exactly a year after the publication of the proclamation, the ambassadors had a formal conference with Sir Julius Cæsar, Sir Thomas Parry, Sir Daniel Dunn, Sir Christopher Perkins, Dr Henry Marten (Advocate-General), and Levinus Muncke, a Fleming, and “clerk to his Majesty’s Signet.” The English commissioners began the discussion by justifying the proclamation on the grounds previously indicated. The Dutch contended for complete freedom of fishing, resting their case on arguments drawn from the civil law, on immemorial possession, on the existence of treaties, and on political considerations. They said the United Provinces had always been in peaceful possession of free fishing, and that from time immemorial they had enjoyed complete liberty to fish over the whole sea, both as a matter of usage and of right. To disturb them by force in the enjoyment of that right would be unjust. Besides, by the Law of Nations the boundless and rolling sea was as common to all people as the air, “which no prince could prohibit.” No prince, they said, could “challenge further into the sea than he can command with a cannon, except gulfs within their land from one point to another,”--the first occasion on which this principle for delimiting territorial waters, afterwards so celebrated, appears to have been advanced.[292] [Illustration: Fig. 7.--_Facsimile of Minute of the Declaration of the Dutch Envoys as to the range of guns._]
