matter that they would probably be obliged to go into a brisk and open
war, in order to prevent the Spaniard from establishing himself in the
duchies. He advised them to notify the Archdukes in Brussels that they
would regard the truce as broken if, under pretext of maintaining the
Emperor's rights, they should molest the princes. He desired them
further to send their forces at once to the frontier of Gelderland under
Prince Maurice, without committing any overt act of hostility, but in
order to show that both the King and the States were thoroughly in
earnest.

The King then sent to Archduke Albert, as well as to the Elector of
Cologne, and despatched a special envoy to the King of Great Britain.

Immediately afterwards came communications from Barneveld to Henry, with
complete adhesion to the King's plans. The States would move in exact
harmony with him, neither before him nor after him, which was precisely
what he wished. He complained bitterly to Aerssens, when he communicated
the Advocate's despatches, of the slothful and timid course of the
princes. He ascribed it to the arts of Leopold, who had written and
inspired many letters against him insinuating that he was secretly in
league and correspondence with the Emperor; that he was going to the
duchies simply in the interest of the Catholics; that he was like Henry
II. only seeking to extend the French frontier; and Leopold, by these
intrigues and falsehoods, had succeeded in filling the princes with
distrust, and they had taken umbrage at the advance of his cavalry.

Henry professed himself incapable of self-seeking or ambition. He meant
to prevent the aggrandizement of Austria, and was impatient at the
dilatoriness and distrust of the princes.
