The King was anxious that the States should send a special embassy at once to the King of Great Britain. His ambassador, de la Boderie, gave little encouragement of assistance from that quarter, but it was at least desirable to secure his neutrality. "'Tis a prince too much devoted to repose," said Henry, "to be likely to help in this war, but at least he must not be allowed to traverse our great designs. He will probably refuse the league offensive and defensive which I have proposed to him, but he must be got, if possible, to pledge himself to the defensive. I mean to assemble my army on the frontier, as if to move upon Julich, and then suddenly sweep down on the Meuse, where, sustained by the States' army and that of the princes, I will strike my blows and finish my enterprise before our adversary has got wind of what is coming. We must embark James in the enterprise if we can, but at any rate we must take measures to prevent his spoiling it." Henry assured the Envoy that no one would know anything of the great undertaking but by its effect; that no one could possibly talk about it with any knowledge except himself, Sully, Villeroy, Barneveld, and Aerssens. With them alone he conferred confidentially, and he doubted not that the States would embrace this opportunity to have done for ever with the Spaniards. He should take the field in person, he said, and with several powerful armies would sweep the enemy away from the Meuse, and after obtaining control of that river would quietly take possession of the sea-coast of Flanders, shut up Archduke Albert between the States and the French, who would thus join hands and unite their frontiers.
