But beneath these brilliant shows there lurked suspicions and fears. Alexander was annoyed that Napoleon retained French garrisons in the fortresses on the Oder and claimed an impossible sum as indemnity from Prussia. This was not the restoration of Prussia's independence, for which he, Alexander, had pleaded; and while the French eagles were at Küstrin, the Russian frontier could not be deemed wholly safe.[200] Then again the Czar had been secretly warned by Talleyrand against complaisance to the French Emperor. "Sire, what are you coming here for? It is for you to save Europe, and you will only succeed in that by resisting Napoleon. The French are civilized, their sovereign is not. The sovereign of Russia is civilized, her people are not. Therefore the sovereign of Russia must be the ally of the French people."[201] We may doubt whether this symmetrical proposition would have had much effect, if Alexander had not received similar warnings from his own ambassador at Paris; and it would seem that too much importance has been assigned to what is termed Talleyrand's _treachery_ at Erfurt.[202] Affairs of high policy are determined, not so much by the logic of words as by the sterner logic of facts. Ever since Tilsit, Napoleon had been prodigal of promises to his ally, but of little else. The alluring visions set forth in his letter of February 2nd were as visionary as ever; and Romantzoff expressed the wish of his countrymen in his remark to Champagny: "We have come to Erfurt to set a limit to this conduct." It was evident that if Napoleon had his way completely, the partition of Turkey would take place at the time and in the manner desired by him; this the Czar was determined to prevent, and therefore turned a deaf ear to his ally's proposal that they should summon Austria to explain her present ambiguous behaviour and frankly to recognize Joseph Bonaparte as King of Spain. 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.
