Empress Zita wrote a letter inviting him to Vienna. Zita's mother
Maria Antonia delivered the letter personally. Another intermediary was
Jozef Retinger, a London-based Polish literary scholar and budding politician who was a friend of Sixtus,
Xavier and Zita of Bourbon-Parma and who had received backing from the British to support the initiative.

Sixtus arrived with French-agreed conditions for talks:
* The restoration to France of
Alsace-Lorraine (annexed by Germany after the
Franco-Prussian War
The Franco-Prussian War or Franco-German War, often referred to in France as the War of 1870, was a conflict between the Second French Empire and the North German Confederation led by the Kingdom of Prussia. Lasting from 19 July 1870 to 28 Janua ...

to Russia.
Charles agreed, in principle, to the first three points and wrote a letter dated 24 March 1917 to Sixtus, giving "the secret and unofficial message that I will use all means and all my personal influence" to the President of France.
This attempt at dynastic diplomacy eventually foundered. Germany refused to negotiate over Alsace-Lorraine and, seeing a Russian collapse on the horizon, was loath to give up the war.

. Clemenceau was incensed and had Emperor Charles' letter to Prince Sixtus published. For a while, there were fears that Germany might occupy Austria. Czernin persuaded Charles to send a 'Word of Honour' to Austria's allies saying that Sixtus had not been authorised to show the letter to the French Government, that Belgium had not been mentioned, and that Clemenceau had lied about the mentioning of the Alsace. Czernin had actually been in contact with the German Embassy throughout the whole crisis, and was attempting to persuade the Emperor to step down because of the Affair. After this failed, Czernin resigned himself.
This affair was an embarrassment to Charles and forced Austria-Hungary into an even more dependent position with regard to its German ally.
