Cunningham's vessel is almost ready to put to sea, and it will be necessary for you not to trust your property on board any vessel that is bound from Harwich to Holland, unless they are under convoy; for Cunningham has got a stout vessel, which is a swift sailer, and has 12 carriage guns, besides swivels, and his crew is a gang of desperadoes, picked up at Dunkirk from amongst the smugglers, &c. He vows revenge for the loss of his two prizes, the Prince of Orange packet boat, and the Joseph; for as soon as he can put to sea, he has declared he will sail to Harwich, where he doubts not but that he shall soon pick up a prize.
