After the relief of Breft, the carl of Salifbury put to fea to guard the coafts according to the or-ders he had received. Sir Robert Knolles fet out alfo from Breft, and arrived at his caftle of Derval. As' foon as this was known, information of it was fent to the duke of Anjou, who was with the con-ftable near Nantes. They gueffed what would be the confequence of this ; for fir Robert broke all the treaties which his coufin had entered into, and font to tell the duke of Anjou and the conftable, that he fhould not keep one article of them, as hfc people had not the power to enter into any treaty without his knowledge and confent. The duke, on hearing this, came in perfon to thç fiege of Derval, third ; or, if the French would not do this, the £ngli(h would advance half of the way on foot, if the French would there meet them on foot: or, if the French would not accept either of thefe proportion», they were bound in juftice to return the hoft&ges, for the Englifh had cheerfully and honourably perfomed the\ç engagement.' t3* CHAP.
