This is visible in the answer of the Emperor [Francis] to the Prince, which came to-day from the Austrian head-quarters." That letter, dated July 9th, was indeed of the most cordial character.

It expressed great pleasure at hearing that "the obstacles which seemed to hinder the co-operation of the forces under your Royal Highness are now removed.

I regard this co-operation as one of the surest supports of the cause which the Powers may once more be called on to defend by a war which can only offer chances of success unless sustained by the greatest and most unanimous measures."[331] Further than this Francis could scarcely go without pledging himself unconditionally to an alliance; and doubtless it was the news of Vittoria that evoked these encouraging assurances.
It is even more certain that the compact of Trachenberg also helped to end the hesitations of Austria.

This compact arose out of the urgent need of adopting a general plan of campaign, and, above all, of ending the disputes between the allied sovereigns and Bernadotte.

The Prince Royal of Sweden had lost their confidence through his failure to save Hamburg from the French and Danes.
