Letter of February 25th to Joseph. Thiébault gives us an odd story that Bernadotte sent an agent, Rainville, to persuade Davoust to join him in attacking the rear of the allies; but that Rainville's nerve so forsook him in Davoust's presence that he turned and bolted for his life!
Caulaincourt to Metternich on March 25th: "Arrived only this [last] night near the Emperor, His Majesty has ... given me all the powers necessary to sign peace with the Ministers of the allied Courts" (Fain, p. 345; Ernouf, "Vie de Maret," p. 634).
Thiers does not mention these overtures of Napoleon, which are surely most characteristic. His whole eastward move was motived by them. Efforts have been made (e.g., by M. de Bacourt in Talleyrand's "Mems.," pt. vii., app. 4) to prove that on the 25th Napoleon was ready to agree to all the allied terms, and thus concede more than was done by Louis XVIII. But there is no proof that he meant to do anything of the sort. The terms of Caulaincourt's note were perfectly vague. Moreover, even on the 28th, when Napoleon was getting alarmed, he had an interview with a captured Austrian diplomatist, Wessenberg, whom he set free in order that he might confer with the Emperor Francis. He told the envoy that France would yet give him support: he wanted the natural frontiers, but would probably make peace on less favourable terms, as he wished to end the war: "I am ready to renounce all the French colonies if I can thereby keep the mouth of the Scheldt for France. England will not insist on my sacrificing Antwerp if Austria does not support her" (Arneth's "Wessenberg," vol. i., p. 188). This extract shows no great desire to meet the allied terms, but rather to separate Austria from her allies. According to Lady Burghersh ("Journals," p. 216), Napoleon admitted to Wessenberg that his position was desperate. I think this was a pleasing fiction of that envoy. There is no proof that Napoleon was wholly cast down till the 29th, when he heard of La Fère Champenoise (Macdonald's "Souvenirs").
