The fleet remained at the Downs, victualling, taking in stores, and waiting for pilots acquainted with the northern coasts, from 24th June to 19th July. The masters of the ships were unwilling to risk the large vessels among “the sands and flats” of the east coast, or where there were no good harbours; and they were all of opinion that if they went at all, they ought to leave before 12th July, in order to fall in with the herring fleet north of Buchan Ness. In any case they declined to go unless pilots were provided, and these had to be obtained from the Cinque Ports and Yarmouth. There was obviously much reluctance in the fleet to go on this expedition. The objections and difficulties were brought to the notice of the king, but Charles stood firm, and expressed his “pleasure” that the northern voyage should be undertaken; and Northumberland before leaving wrote to Windebank to assure him that the fleet would decide the business they had in hand, for either the Dutch would take the licenses and pay the acknowledgment, or else the fleet “would put an end to that work.” There could be no doubt of success, because the men, he assured Windebank, were full of resolution to do the king’s service and gain credit to themselves. At the same time, he asked for further instructions with regard to his stay among the busses--those he had received, he said, being like oracles.[537] On July 19 the English fleet weighed anchor and shaped its course northwards in its expedition against the Dutch herring-boats. It consisted of sixteen ships, one Whelp, and a frigate; and both Vice-Admiral Sir John Pennington and Rear-Admiral Sir Henry Mervin accompanied the Earl. Contrary winds compelled them to come again to anchor, but on the 22nd a fair breeze carried them to the north of Cromer, on the Norfolk coast. On Sunday, 24th, when at Tynemouth, the Admiral called all his captains together and gave them precise instructions in the event of their meeting with any considerable opposition from the States’ men-of-war guarding the busses. On the 25th, 26th, and 27th, foul and misty weather caused them to ride at anchor ten leagues off the coast. About noon on the 28th they descried sixteen sail of herring-busses accompanied by one man-of-war; and immediately the Dutch skippers observed the English fleet they made off “with all the sails they could pack on.” Northumberland’s unwieldy ships started in pursuit--“but in vain,” wrote the Earl, “for none of our ships could come near them.” The States’ man-of-war was less fortunate or more courageous. It was from the first far astern of the busses, and it was soon overtaken by the _Swan_--which, it may be noted, was a Dunkirk privateer that had been captured and converted into an English warship. Northumberland kept the Dutch captain on board his own ship, the _Triumph_, all night, expecting, as he said, that the busses would not go far without him--for of course they were liable to be swooped upon by the privateers.
