In the mean time, the earle of Flanders perceiuing that he was not able to resist so puissant an enimie as the French king, sent ouer in hast vnto the king of England for aid. Wherevpon king John vnderstanding that his aduersarie king Philip had turned all his force against the earle of Flanders, and that thereby he was deliuered out of the feare of the Frenchmens comming into England; that same nauie (which as before is recited) he had put in a readinesse, conteining the number of fiue hundred saile, he sent streight into Flanders with a strong armie, both of horssemen and footmen, vnder the guiding of William duke of Holland, William Longspée earle of Salisburie base brother to king John, and Reignold earle of Bullongne. These capteins being now passed foorth with their fléets into the maine sea, espied anon manie ships lieng without the hauen of Dam (for the number of ships of the French fléet was so great, that the hauen could not receiue them all, so that manie of them laie at anchor without the hauen mouth, and all alongst the coast.) Wherefore they sent foorth certeine shallops, to espie whether they were fréends or enimies, and what their number and order was. It chanced, that the same time the men of warre which were appointed to kéepe the French fléet, were gone foorth, togither with a great number of the mariners, to spoile and fetch booties abroad in the countrie. [Sidenote: The English men assaile the French ships.] The English espials therefore, making semblance as though they had béene some fishermen of those parts, came verie néere the French ships lieng at anchor, and perceiuing them to be vnfurnished of people necessarie to defend them, came backe to their companie, and declared what they had séene, certifieng their capteins that the victorie was in their hands, if they would make spéed. The capteins glad of these newes, commanded their men to make them readie to giue battell, and causing their mariners to make saile directlie towards the French fléet, at their first approch they wanne those tall ships that laie at anchor abroad before the hauen, without any great resistance, the mariners onelie making request to haue their liues saued. The other smaller vessels which (after the tide was gone) remained vpon the sands (spoiling them first of their tackle and other things that would serue to vse) they consumed with fire, the mariners escaping by flight.
