In the mean time, the Due de Guise, having reduced the cities on the southern frontier, was to move in a northerly direction, make a junction with the Marshal, and thus extend a barrier along the whole frontier of the Netherlands.
De Therlries set forth from Calais, in the beginning of June, with his newly-organized army.

Passing by Gravelines and Bourbourg, he arrived before Dunkerk on the 2d of July.

The city, which was without a garrison, opened negotiations, during the pendency of which it was taken by assault and pillaged.

The town of Saint Winochsberg shared the same fate.

De Thermes, who was a martyr to the gout, was obliged at this point temporarily to resign the command to d'Estonteville, a ferocious soldier, who led the predatory army as far as Niewport, burning, killing, ravishing, plundering, as they went.
