If Austria put a stop to her present armaments, the supremacy of Napoleon in Central Europe would be alarmingly great.
Clearly it was not to Russia's interest to weaken the only buffer-state that remained between her and the Empire of the West.
These fears were quietly fed by a special envoy of the Court of Vienna, Baron Vincent, who brought complimentary notes to the two Emperors and remained to feel the pulse of European policy.

It boded peace for Austria for the present.

Despite Napoleon's eager arguments that England would never make peace until Austria accepted the present situation in Spain, Alexander quietly but firmly refused to take any steps to depress the Hapsburg Power.

The discussions waxed warm; for Napoleon saw that, unless the Court of Vienna were coerced, England would persist in aiding the Spanish patriots; and Alexander showed an unexpected obstinacy.

Napoleon's plea, that peace could only be assured by the entire discouragement of England, Austria, and the Spanish "rebels," had no effect on him: in fact, he began to question the sincerity of a peacemaker whose methods were war and intimidation.
Finding arguments useless, Napoleon had recourse to anger.
