In the spring of 1647, the Committee of the Admiralty, for some reason or other, appears to have devoted special attention to the question of the flag and the sovereignty of the sea. Collections were made from the Admiralty archives of precedents showing that all ships refusing to strike in English waters were to be reputed enemies, and were liable to forfeiture,--the examples beginning with the Ordinance of King John and ending with the instructions issued by Charles.[684] These collections were probably made in connection with the instructions which the Committee drew up at this time for the guidance of the captains and officers of the navy, and which were essentially similar to those given by Charles to his ship-money fleets. “It must be your principal care,” they ran, “to preserve the honour of this kingdom, and the coasts, jurisdictions, territories, and subjects thereof, being in amity with the Parliament, and within the extent of your employment, as much as in you lieth; that no nation or people whatsoever intrude thereon or injure any of them. And if you chance to meet in any of the seas that are under the jurisdiction of England, Scotland, and Ireland, with any ships or fleets belonging to any foreign prince or state, you must expect that they, in acknowledgment of this kingdom’s sovereignty there, shall perform their duty and homage in passing by, in striking their top-sails and taking in their flags.” If they refused they were to be forced to do so in the usual way. It will be noticed that the region within which foreigners were to be compelled to strike was greatly extended by the Parliament. Up to and including the reign of James the “acknowledgment” was confined to the narrow seas, in which it had been exacted for centuries; Charles in 1635 ordered Lindsey to compel it “in his Majesty’s seas,” and now the Parliament extended it specifically to all the seas under the jurisdiction of England, Scotland, and Ireland. From a clause in the instructions it is clear that the seas over which the Parliament claimed sovereignty reached to the coasts of the Continent; but a territorial limit was excepted on foreign coasts. The clause in question enjoined the naval officers “to be very careful not to meddle with any ships within the harbours, or ports, or under the command of any of the castles of any foreign prince or state, or within any buoys (Buoyes) or rivers, that they may have no just cause of offence.” Another feature of these instructions is of interest. The clause which was inserted in the instructions to Lindsey and Northumberland in 1635, 1636, and 1637, commanding them to prevent all hostilities between men-of-war or merchant vessels in the presence of the king’s ships, was repeated.[685] The Parliament clearly intended to abate no jot of the pretensions which had been put forward by the king.
