In July, he met the Dutch fishery fleet, with a convoy of twelve men of war, all which he took, with one hundred of their herring-busses. And, in September, being stationed in the Downs, with about sixty sail, he discovered the Dutch admirals, De Witt and De Ruyter, with near the same number, and advanced towards them; but the Dutch being obliged, by the nature of their coast, and shallowness of their rivers, to build their ships in such a manner, that they require less depth of water than the English vessels, took advantage of the form of their shipping, and sheltered themselves behind a flat, called Kentish Knock; so that the English, finding some of their ships aground, were obliged to alter their course; but perceiving, early the next morning, that the Hollanders had forsaken their station, they pursued them with all the speed that the wind, which was weak and uncertain, allowed, but found themselves unable to reach them with the bulk of their fleet, and, therefore, detached some of the lightest frigates to chase them. These came so near, as to fire upon them about three in the afternoon; but the Dutch, instead of tacking about, hoisted their sails, steered toward their own coast, and finding themselves, the next day, followed by the whole English fleet, retired into Goree. The sailors were eager to attack them in their own harbours; but a council of war being convened, it was judged imprudent to hazard the fleet upon the shoals, or to engage in any important enterprise, without a fresh supply of provisions.
