‘It was all that could be spared, sire. Until the last of my divisions arrived,’ Davout explained. ‘The Prussians threw in a massive attack against our right, which we beat back with heavy losses on their part. But then they immediately advanced on our left, and broke the regiment I had left there. As soon as the right flank looked safe I rode across to the left, taking two of Gudin’s regiments, and rallied the broken regiment. We charged the enemy and drove them back and retook the village.’

‘You led the charge in person?’

Davout looked at him steadily. ‘Yes, sire. As I said, we needed every man who could hold a musket. There were no exceptions. I even had the men in the supply wagons armed and brought forward as a final reserve.’

Napoleon nodded approvingly, as he realised how desperate Davout’s situation had been. ‘What then?’

‘The Prussians mounted four more assaults on the village, but we drove them off.’

‘Must have been a hard fight.’

‘Yes, sire. I have never seen my men so resolute. So brave.’

Napoleon smiled. ‘I am equally certain that they have never seen a marshal fight at their side before.Your men are a credit to you, as you are to them.’

Davout shrugged modestly. ‘We were fortunate, sire. The Prussians played their part as well. They were slow to attack, and when they did it was always piecemeal and poorly co-ordinated, so I was able to move men along my line to meet any dangers. But we were losing men all the time, sire, and Morand arrived only just in time to hold the left flank. But there was no sign of Bernadotte, and I heard nothing from him until noon, when a message arrived saying that he would not move without instructions from you, sire.’

‘Really?’ Napoleon folded his hands together. Bernadotte’s orders had been clear enough. He was to work in concert with Davout, with the latter acting as his immediate superior. His refusal to march to Davout’s aid could have led to the latter’s defeat and the victory at Jena would have amounted to nothing. Napoleon resolved to have Bernadotte called to account for his dangerous inactivity. ‘Continue.’
