To both of these requests Haugwitz assented, and pledged the word of his King, an act of presumption which that monarch was to repudiate.
While exceeding his instructions on this side, Haugwitz did practically nothing to advance the chief business of his mission.
Either his own fears, or the crafty mixture of threats and flattery that cajoled so many envoys, led him to neglect the interests of Prussia, and to play into the hands of the very man whose ambition he was sent to check.

After the interview, when the envoy had retired to his lodging, Caulaincourt came up in haste to warn him that a battle was imminent, that his personal safety might be endangered, and that Napoleon requested him to repair to Vienna, where he might consult with Talleyrand on affairs of State.

Horses and an escort were ready, and Haugwitz set out for that city, where he arrived on November 30th, only to find that Talleyrand was strictly forbidden to do more than entertain him with commonplaces.

Thus, the all-important question as to the action of Prussia's legions was again postponed, even when 150,000 Prussians and Saxons were ready to march against the French communications.
