Henry of France was especially indignant at what he considered the
shortcomings of the republic and of its chief. Already, before the close
of the summer, the agent Aerssens had written from Paris that his Majesty
was very much displeased with Spinola's prosperity, ascribing it to the
want of good councils on the part of the States' Government that so fine
an army should lie idle so long, without making an attempt to relieve the
beleaguered places, so that Spinola felt assured of taking anything as
soon as he made his appearance. "Your Mightinesses cannot believe,"
continued the agent, "what a trophy is made by the Spanish ministers out
of these little exploits, and they have so much address at this court,
that if such things continue they may produce still greater results."

In December he wrote that the king was so malcontent concerning the siege
of Groll as to make it impossible to answer him with arguments, that he
openly expressed regret at not having employed the money lent to the
States upon strengthening his own frontiers, so distrustful was he of
their capacity for managing affairs, and that he mentioned with disgust
statements received from his ambassador at Brussels and from the Duc de
Rohan, to the effect that Spinola had between five and six thousand men
only at the relief of Groll, against twelve thousand in the stadholder's
army.

The motives of the deeds and the omissions of the prince at this supreme
moment must be pondered with great caution. The States-General had
doubtless been inclined for vigorous movements, and Olden-Barneveld, with
some of his colleagues, had visited the camp late in September to urge
the relief of Rheinberg. Maurice was in daily correspondence with the
Government, and regularly demanded their advice, by which, on many former
occasions, he had bound himself, even when it was in conflict with his
own better judgment.
