‘Then let us hope he had the sense to drive on through them and march to the sound of the guns here at Dresden.’

As the rain continued, the sound of musket and cannon fire began to dwindle. The left flank had been fought to a standstill, but over on the right Napoleon saw that Murat had unleashed his cavalry. The wet ground was making movement difficult and Napoleon slapped his thigh in delight as he saw large pockets of enemy soldiers trapped in the muddy fields surrounded by French cavalry and forced to surrender. By mid-afternoon the enemy’s left flank had all but ceased to exist. But the centre still held, impervious to the frequent attacks that the French soldiers made at bayonet point.

At length, Napoleon took a deep breath. ‘The army has done all it can for today, Berthier. This rain is bogging us down. Give the order to break off the attack. The men can spend another night under cover, and the enemy in the open, and we’ll see how quickly their spirit breaks tomorrow.’

‘Yes, sire.’

‘And I want reports from every division. Butcher’s bills, and the number of enemy captured and their casualties. By nightfall. There’s another day of battle to prepare for,’ he concluded irritably. ‘Tomorrow we will finish this.’

The rain finally ended as dusk shrouded the battlefield and mercifully concealed the bodies and limbs stuck in the sprawl of mud churned up by the passage of many thousands of men, horses and heavy wooden wheels. The men of the Grand Army marched back to their billets, weary and wet but still in fine spirits, unlike the long column of prisoners that was escorted over the Elbe to spend yet another night in the open. Berthier collated the battle reports that came in from across the army and presented the final assessment to his Emperor as he sat wrapped in a blanket and close to a brazier set up in the nave. It had been several days since Napoleon had slept well, and exhaustion, together with the damp conditions, had combined to give him a slight fever. He trembled as he huddled over the fire.

‘Sire, do you wish me to send for your surgeon?’ Berthier asked anxiously.

‘No. It will pass. Besides, I can rest after tomorrow.’ Napoleon’s face contorted for a moment and then he sneezed.

‘Shall I order some soup for you, sire?’

Napoleon shook his head. His stomach was acutely uncomfortable and the idea of any food at all made him feel queasy. He glanced up at Berthier and nodded towards the papers in the latter’s hands. ‘Are those the reports?’

‘Yes, sire.’

‘Give me the summary.’

‘We have taken some twelve thousand prisoners, and after the body count, allowing for the usual proportion of wounded, the enemy suffered a total loss of over thirty-five thousand men. In addition, we have taken twenty-six guns, and thirty ammunition wagons.’

‘And our losses?’
