Cromwell throughout the whole negotiations, until he became Lord Protector, acted as spokesman for the Council at the conferences; and he now stated that the visitation of Dutch ships was an undoubted right of sovereignty possessed by the English Commonwealth. The limitation of their ships of war passing through the British seas was also a consequence of the same right of dominion; and the English had now more than ever reason to maintain it, both on account of their ancient prerogative and the recent injuries committed by the Dutch. The right to the fishery was of the same nature. No other nation in Europe had attempted to carry it on without the consent of England; the Dutch were the only people, he said, who sought a separate interest in it--a statement which was quite inaccurate. But the deputies took their stand on the obnoxious article which proposed to clip their naval power and interfere with their liberty of navigation, and threatened to return home unless it was withdrawn. After standing firm for a time Cromwell withdrew the article, asserting at the same time that England had jurisdiction on both sides of the sea, and that it was perilous to allow a fleet of sixty or eighty men-of-war to come into our rivers or ports without our knowledge or consent,--a reference, no doubt, to Tromp’s action before the war. This concession facilitated the negotiations. Frequent conferences were held in the following week, Cromwell and his Council strongly asserting the right of the Commonwealth to the fisheries and the dominion of the sea. At this period there were four subjects chiefly in dispute--the arrangements relating to the striking of the flag, the visitation of ships of war, the preliminary part of the sixteenth article as to the guarding of the seas, and the fishery. On none of these was Cromwell inclined as yet to give way. The deputies repeated their offer as to the flag, and requested that a joint commission of old and experienced naval officers should be appointed to draw up regulations for the guidance of both sides in future. To this Cromwell replied that such a commission was unnecessary, their rights and the custom being well understood and clearly expressed in the article. There was, however, uncertainty as to the places where the right could be claimed, and the Dutch deputies said they wished to make it clear in what seas and on what coasts the flag ought to be struck, urging that it was better to be guided by a regulation than to compel it by force. But Cromwell was inflexible. To yield would be to admit that the claim was doubtful in point of right or mode, and it would stultify their whole action; he may also have thought it would open a door for some form of reciprocity. The article was therefore postponed, as was also the sixteenth article, the deputies insisting on the deletion of the introductory sentence as to a fleet to be put forth to guard the sea, which Cromwell refused to do.[770]
