Concessions were also made as to the striking of the flag. “The 15 article,” said Cromwell, “to be as following: that the ships and vessels of the United Provinces, as well men-of-war as others, meeting at sea with any of the ships of war of the State of England, shall strike their flag and lower their top-sail, and perform the other respects due to this State until they be passed by”; but the request that a naval commission should draw up a “regulation” on the subject was not acceded to. On the other hand, the clauses which stipulated for a right of visitation of Dutch ships at sea, and the declaration that the dominion and sovereignty of the sea belonged to England, were entirely withdrawn; but the Protector would not yet part with the clause which provided for an English fleet to guard the seas and protect commerce. Surely, he said in effect, since the article limiting the number of warships has been withdrawn, you will not contest our dominion of the sea in this?--and at this stage it was retained, with the remark, “this article is insisted on.” One of the new clauses provided that not more than eight men-of-war at a time were to enter any port of the other Power, unless constrained by force of tempest, without having obtained consent to do so; and when compelled to enter by danger of the sea, they were immediately to signify to the chief magistrate the cause of their coming, and to leave when he required them to depart.[787] On the subject of striking the flag, the deputies were not yet satisfied. They still continued to urge that a “regulation” should be prepared; and they now raised a new point. Cromwell had always used the words “at sea,” which might mean any sea or any part of the sea. They now desired that the ceremony should be restricted to the narrow seas, “which,” they said, “are called the British seas.”[788] To this proposal Cromwell assented in so far that the words “in the British seas” were inserted later. It is curious to notice how the meaning of the term “British Sea” thus became confused even within the compass of a single treaty. In reference to this article, the Protector made the important admission that the narrow seas and the British seas were synonymous.[789] In the third article, as we have seen, the same term was used, and it was natural for the Dutch to suppose that it there had the same significance and meant the narrow seas or Channel. Since the clause dealt with a matter of great practical importance, namely, the restitution of vessels that might be captured after a specified date, and the term “British seas” appeared to be restricted to the Channel, they wished specifically to include in it the North Sea and the East Sea (or Baltic), both regions of great traffic. The envoys were accordingly instructed later by the States-General to have these words added, so that the clause would read, “excepting such depredations as shall be committed in the British Sea, the East Sea,
