But the equipment of the fleet and army was so dilatory that the French got intelligence of the design, and were prepared to receive them.

The English found Brest so well guarded as to render an attempt on that place impracticable; but, landing at Conquet, they plundered and burnt the town, with some adjacent villages, and were proceeding to commit greater disorders, when Kersimon, a Breton gentleman, at the head of some militia, fell upon them, put them to rout, and drove them to their ships with considerable loss.

But a small squadron of ten English ships had an opportunity of amply revenging this disgrace upon the French.
The mareschal de Thermes, governor of Calais, had made an irruption into Flanders, with an army of fourteen thousand men, and, having forced a passage over the River Aa, had taken Dunkirk and Berg St.Winoc, and had advanced as far as Newport; but Count Egmont coming suddenly upon him with superior forces, he was obliged to retreat; and being overtaken by the Spaniards near Gravelines, and finding a battle inevitable, he chose very skilfully his ground for the engagement.

He fortified his left wing with all the precautions possible, and posted his right along the River Aa, which, he reasonably thought, gave him full security from that quarter.

But the English ships, which were accidently on the coast, being drawn by the noise of the firing, sailed up the river, and, flanking the French, did such execution by their artillery that they put them to flight, and the Spaniards gained a complete victory.[*] * Holigshed, p.
