The calamity soon brought over the Dutch fleet to protect the remaining busses. Van Dorp, with fourteen French and Dutch men-of-war, arrived in Calais Road about the middle of August and sailed thence northwards, thirsting for vengeance on the freebooters. Lindsey detached some of the ships from his fleet, which lay victualling in the Downs, for convoys, as well as to punish the “contempt” of the Dutch at Scarborough (see p. 250), and a few of the smaller vessels were engaged in looking for “picaroons” in the Straits of Dover. For during the absence of the fleet, the post-boat between Dover and Dunkirk had been attacked and pillaged five times within seven weeks, and the packages containing the king’s letters opened.[496] A French man-of-war, too, had taken an English ship off Harwich and carried her off to Boulogne. Such occurrences, and the presence of Van Dorp in the north, delayed Lindsey’s departure. But on 4th September he again left the Downs with most of his ships, stood over to Calais and ranged the French coast for some distance southwards, and then out to sea. Heavy weather coming on, he had to run for shelter to the Isle of Wight, where the fleet lay weather-bound, and with much sickness on board, from the 12th till the 29th September. The Admiral then made for the Downs, where he arrived on 4th October, and on the 8th he struck his flag.[497] Pennington was left with seven ships for the winter guard of the narrow seas; and with “private” instructions from the Earl not to suffer any breach of the peace to be done to any of his Majesty’s allies, nor to permit his sovereignty to be infringed upon; to give convoys to merchants when they wished it; to clear his Majesty’s seas of pirates, and to compel the “due homage of the sea.” Finally, he was to assist the farmers of the customs, particularly in preventing the smuggling of tobacco.
