Frederick himself was quite aware of his danger. "I'm at the end of my resources," he wrote at the beginning of 1760. "The continuance of this war means for me utter ruin. Things may drag on perhaps till July, but then a catastrophe must come." On 21 May 1760, a fresh convention was signed between Russia and Austria, a secret clause of which, never communicated to the court of Versailles, guaranteed East Prussia to Russia as an indemnity for war expenses. The failure of the campaign of 1760, wielded by the inept Count Buturlin, induced the court of Versailles on the evening of 22 January 1761 to present to the court of Saint Petersburg a dispatch to the effect that the king of France, by reason of the condition of his dominions, absolutely desired peace. The Russian empress' reply was delivered to the two ambassadors on 12 February. It was inspired by the most uncompromising hostility towards the king of Prussia. Elizabeth would not consent to any pacific overtures until the original object of the league had been accomplished.
