There was nothing left but to retrieve whatever political advantage there might be in taking the enemy capital. That at least would humiliate Austria in the eyes of the other nations of Europe, and make them think hard about defying Napoleon.The Emperor frowned as he reflected on the coming confrontation with Murat, who had been summoned to headquarters to report to him in person. Like any good cavalry commander, Murat was fearless in attack and resolute in defence, but his kind tended to suffer from far too much pride, arrogance and impetuosity. In Murat these qualities, both good and bad, had been refined to an unusual degree. It was time to rein Murat in, Napoleon mused humourlessly.

When he returned to the large farm commandeered by the headquarters staff, Napoleon heard a loud roar of laughter coming from within. He nodded at the sentry, who saluted, and then opened the door of the farmhouse. He paused on the threshold as he heard Murat’s voice carrying across the merriment of his staff officers and members of the imperial headquarters. Napoleon removed his hat and quietly made his way inside, to stand at the side of the hall in the shadows as he watched Murat holding court. The glow of the fire and the candles flickering around the room picked out the elaborate gold braid and bejewelled decorations that covered the cavalry commander’s tunic.

‘You should have seen it!’ Murat continued. ‘The bastards were on the far side of the bridge, with guns covering it and a brigade of infantry formed in line across the end on the far bank.The Austrians had mined it as well, just to make sure. Any attempt to cross would have ended in a bloodbath. So, there’s Marshal Lannes and myself looking across the Danube and Lannes calls up the grenadiers and tells ’em to keep out of sight on our side of the river and wait for his signal.Then Lannes and I start walking across the bridge to the Austrian side. Just him and me. Alone.’ Murat paused, milking the suspense and relishing every moment of it, before he continued. ‘Well, soon as they see us the Austrians raise their muskets, and the gunners bring up their linstocks, and wait for the order to open fire.Then Lannes and I raise our arms and wave ’em, and start shouting “Armistice! Armistice!” for all we’re worth.’ Murat accompanied his words with great sweeps of his arm to dramatise the point.‘You should have seen their faces! The colonel in command of the defences just stood there as we walked up.’ Murat assumed an aristocratic falsetto. ‘ “Armistice?” he says. “What armistice? No one’s told me.” ’
