‘I will not permit Prussia to retain any such potential while that scheming witch Queen Louise is able to influence her husband and the Prussian court against me. I have not defeated an enemy only to present them with the chance to do me further harm at a future date. No. Prussia will be made to suffer so that she learns the cost of defying me. As for the Tsar, you will do what is necessary to secure the best terms for France while offering Alexander anything that might cement the peace between our nations. Within reason, of course.’

‘Of course.’ Talleyrand nodded. ‘Though I would still ask your majesty to consider what I have said. Russia is not our natural ally, and it would serve France better to end the war with Britain than take Russia as an ally against her.’

‘Thank you, Talleyrand. I have noted your opinion. You have your instructions, and I require you to carry them out. Is that clear?’

‘Yes, your majesty.’ Talleyrand bowed his head.

‘Then you may go.’

The foreign minister eased himself up and walked stiffly to the door, where he bowed again before leaving the room. Napoleon stared at the door for a moment, his lips compressing into a thin line. He felt a cold rage in his heart at Talleyrand’s questioning of his judgement. The foreign minister seemed to think that diplomacy must be conducted at the speed of a glacier. The truth was that people had short memories. Yesterday’s villain was interchangeable with today’s hero. Napoleon sniffed with derision. He knew that the very same mob in Paris that had cried out for the blood of the Tsar would be cheering him the moment peace was announced. Talleyrand was wrong. Diplomacy was like war. It was largely a question of arranging the pieces correctly, with a certain amount of bluff and luck. Rising from his chair, Napoleon yawned. As he made his way back to his sleeping quarters he decided that he must write to Fouché and order him to have his agents watch Talleyrand closely. It would be an easy step from disagreeing with the Emperor to plotting against him.

July had arrived and the days were long and hot. Even though the tall windows of the chamber were left open, the atmosphere inside was uncomfortable and heavy. There were no concessions to the summer temperature, however, and all those in attendance wore their finest uniforms and coats. Sweat pricked out on every man’s brow and the hours dragged on as the terms of the treaty were put forward and debated. Some sessions were attended by representatives of all three nations, but most concerned only the Russians and the French, and the hapless Prussians were excluded.
