There was, however, one element of weakness in the position of the United Provinces on which the English were never weary of insisting. By his possession of the cautionary towns the King of England appeared in the eyes of the world to be recognized as a protector of the Dutch Republic, who had certain rights over it. Oldenbarneveldt in his negotiations had doubtless been hampered by the plain evidence which the presence of English garrisons in Flushing, Brill, and Rammekens afforded, that the States did not exercise full sovereign authority within their own borders. In these circumstances he (Oldenbarneveldt) knowing full well the financial straits to which King James was reduced through the long-standing disagreement between him and his Parliament, made overtures in 1615 through the resident ambassador Caron to redeem the towns by the payment of a sum of ready money. The annual charge of £40,000 received from the States was barely more than sufficient for the maintenance of the garrisons. The total amount claimed by the English Government was £600,000; the Dutch offered £100,000 in cash, and three further sums of £50,000 in half-yearly instalments, or £250,000 in all. The offer was accepted and in June, 1616, the cautionary towns were transferred into the hands of the Dutch.
It was, however, agreed that, for the sake of maintaining good relations between the two countries, the new English ambassador, Sir Dudley Carleton, should like his predecessor, Sir Ralph Winwood, retain his seat in the Council of State. This was the more important, as the King had (as already stated) for the past three years been steadily moving towards a Spanish alliance. What were his precise aims and what his ultimate purpose it was difficult even for the practised and penetrating insight of a statesman of Oldenbarneveldt's experience to discover. Perhaps James scarcely knew himself. But the retention of fortresses like Flushing and Brill at the mouths of two most important Dutch waterways by a foreign sovereign, who was intriguing to win the favour of the Spanish foe, was for the Republic a most serious danger. Their redemption therefore at so trifling a cost was a stroke of policy by which the aged Advocate did a great service to his country. Certain it is that James felt a grudge against Oldenbarneveldt, and that, when shortly afterwards civil strife broke out in the United Provinces, Sir D. Carleton, acting on the King's instructions, did his utmost to bring about the great statesman's downfall and to support his enemies in compassing his death.
But to return. Sir Dudley Carleton, when entering upon his duties at the Hague in January, 1616, found, in addition to the negotiations for the 'reddition' of the cautionary towns, several thorny questions requiring delicate handling. In his instructions25 the following somewhat enigmatical passage occurs: —
'Some two years since there did arise between the Company of our Muscovy Merchants and the Merchants of Amsterdam a great difference concerning the navigation of Greenland26 and the fishing of whales in those parts. Our desire is that all good correspondence may be maintained, as between our Crowns and their Provinces, so between our and their subjects. Therefore, whenever the subject shall fall into discourse, either in public or in private, you may confidently relate, when this question was debated before the lords of the Council, between Sir Noel Caron their embassador and the Governor of our Muscovian Company, it was evidently proved, and in a manner without contradiction, that our subjects were first discoverers of that negotiation and that trade of fishing; that privately they were possessed of that island, and there had planted and erected our standard, thereby to signify and notify to the world the property, which we challenge; which our subjects, by their industries, having appropriated to themselves, did not hold it reasonable they should be forced to communicate to others the fruits of their labours.'
The origin and cause of this new fishery dispute requires to be briefly told, as it is characteristic of the times and of the way in which, in almost every part of the world, the English trader and the Dutch trader met in rivalry, and with the inevitable result that their interests clashed and bad feeling arose. Certain English fishing vessels as early as 1608 made their way to the Arctic Ocean to fish for whales off the shores of Spitzbergen. The adventure was successful, and was repeated. The news of it attracted some Biscayans, then other foreigners, and in 1612 two Dutch ships to try their fortune in the same waters. But King James in the following year (1613) granted to the Muscovy Company an exclusive monopoly of the Greenland, meaning thereby the Spitzbergen, whale fishery. He claimed these northern waters as the property of the British Crown, because, so it was averred, Hugh Willoughby had in 1553 discovered Spitzbergen. The conferring of this monopoly caused in 1613 a numerous fishing fleet, some of the vessels strongly armed, to set sail from England for Spitzbergen. A landing was made, and the whole archipelago formally annexed and named King James' Newland. The next step of the Muscovy Company's fleet was to clear the ground of intruders, whether foreigners or English 'interlopers.' Among the foreigners were several Dutch boats. These were attacked, boarded, plundered, and then sent home.
Such an act of violence naturally aroused resentment in Holland. The States-General took the matter up, and refused to admit the right of James to interfere with the fishermen. They denied that Hugh Willoughby had sighted Spitzbergen at all in 1553, and confidently affirmed that the discovery of the island was made by Jacob van Heemskerk in 1596, who named it Spitzbergen, planted the Dutch flag upon it, and spent the winter on its shores. If, then, any people had preferential rights in the waters surrounding Spitzbergen, it was the Dutch, but the States did not claim or admit any such rights. They held that the sea was open to all to navigate and to fish in without let or hindrance. To Winwood, who in August, 1613, quitted the Hague to become Secretary of State in London, was entrusted the mission of bringing the complaints and the protest of the States to the notice of James, and further, of asking for reparation to the Amsterdammers, whose vessels had been seized and plundered. The King at this time was anxious to be on friendly terms with the Dutch, and an answer was returned (October 25) that 'not only reparation should be made, but that steps should be taken to prevent a recurrence of such disorders.' The States were not satisfied, however, with so general a reply, and wished that the English claim to exclusive rights in the fisheries should be abandoned. The ambassador Caron was instructed to present to the King an argument from the pen of the geographer Plancius, in which this claim was shown to be without foundation. It produced no effect upon James, always unwilling to yield in a matter affecting his sovereign prerogatives, however shadowy. But the States were equally determined. Their reply to the non-possumus attitude of the King was the granting of a charter, early in 1614 (January 27), to a company, generally known as the Northern (sometimes as the Greenland) Company, which conferred on a group of merchants the exclusive privilege of fishing for whales and walrus, and of trading and exploring in the Northern seas between the limits of Nova Zembla and Davis's Straits; Spitzbergen, Bear Island, and Greenland therein included.27 The States-General likewise consented that warships at the charges of the company should be allowed to accompany the fishing fleet for their protection (April 4). The effect of these strong measures was seen in the changed attitude of the Muscovy Company, who in the summer of 1614 (July 2) made an agreement with their rivals, that they should each of them use a portion of the island as a basis for their fishery, and should unite in keeping out all intruders. The extraordinary mission of Sir Henry Wotton in February, 1615, to the Hague to treat for a settlement of the Jülich-Cleves question, gave an opportunity for proposing that he should, while in the Netherlands, meet Commissioners of the States to discuss also other important matters, and among these the dispute about the so-called 'Greenland' fisheries. In April the conference took place. The Dutch, while laying stress upon their primary rights as discoverers, disclaimed any desire to exclude the English; on the contrary, they endeavoured to arrive at a friendly arrangement by which the two nations should
