Kaunitz, though he had no eye for such things, took alarm at last, and resolved that the way to depress France was to assist the king of France. On January 5, after the queen's letter of December 16 had been received, he declared that Austria would support the elector of Treves, and would repel force by force, if he was attacked for the harbouring of _emigres_. At the same moment Leopold resolved on an offensive alliance with Prussia. He explained his change of policy by the letters which showed him the true mind of the queen. On January 16 Kaunitz still believed that the other Powers would refuse to co-operate. But Prussia was willing to accept the new alliance, if Austria abandoned the new Polish Constitution of May 3. Leopold paid the stipulated price. On February 7 he gave up the Poles, that he might be strong against France. Already, January 25, Kaunitz had taken the deciding step, passing over from the defensive to attack. He speaks no more of the king's liberty of action. He demands restitution of the papal territory at Avignon, annexed in consequence of the Pope's action against the ecclesiastical laws. He requires that the German princes shall have their Alsatian domains given back to them, and that there shall be no trespass on the imperial dominions. And in general terms he requires the restoration of monarchy. Again he wrote, in the same warlike and defiant spirit, on February 17, when the Prussian signature had been received, and when he expected English aid for the preservation of Belgium. Meantime Simolin, the Russian minister who had been helpful in procuring the fatal passport, arrived at Vienna with a last appeal from the queen. At that time she did not feel that their lives were in jeopardy, but their power. To the faithful Fersen she wrote that she hoped the enemy would strike home, so that the French, in their terror, might pray the king to intercede. Kaunitz, having despatched his ultimatum on the international grounds of quarrel, declined to interfere in internal affairs. But Simolin saw Leopold on the 25th, and then the emperor admitted what his chancellor denied, that the cause was the common cause of all crowned heads. With those significant words he quits the stage. Five days later he was dead.
