Soult’s lips tightened into a thin line as he saluted and spurred his horse away from the Emperor towards the nearest of his batteries, which had ceased fire as the French infantry closed with any Austrian units that still offered resistance. As soon as the order was given Napoleon watched Soult move on to the next battery. Round shot howled over the heads of the Austrians streaming away from the battlefield. Thousands were slithering across the frozen lakes as the heavy iron balls fell around them, shattering the ice and pitching men, horses, gun carriages and cannon into the freezing water beneath. Many were carried under by the weight of their uniform and equipment, but the strongest flailed for purchase on the unstable chunks of ice, struggling for a while before the cold sapped their energy and they slid beneath the dark surface of the water to join their comrades. Napoleon watched in silence as his enemies drowned in their hundreds. It was a sickening sight, and he was tempted to order the guns to cease fire, but he reminded himself of the brutal necessity of breaking the enemy’s will to continue the fight. The more Austrians who perished in this battle the greater the chance of peace.

As the late afternoon sun angled down across the battlefield the guns and musket fire finally died away, and the quiet and stillness were strangely unsettling after the din of long hours of fighting. In the cool blue haze of a winter dusk Napoleon surveyed a landscape of bodies and wrecked guns and wagons. Smoke still swirled into the sky from buildings that had been set on fire during the fighting along the Goldbach stream. Most of the soldiers of the Grand Army sat on the ground, or leaned on their muskets as they looked on the devastation around them. Already the more opportunistic were walking amongst the heaps of enemy corpses looting the bodies of the dead, and finishing off any of the wounded who tried to resist their predations. Elsewhere thousands of Austrian prisoners were herded together under the watchful eyes of a screen of guards.

Napoleon bowed his head in a brief greeting as Soult rode up to him. ‘Congratulations, sire. A famous victory.’

‘It will be,’ Napoleon agreed. ‘Once Fouché applies a little pressure to the newspapers back in France.’

Soult chuckled at what he thought to be his Emperor’s self-deprecation. ‘A great victory by any measure, sire.’

‘We’ll know the measure soon enough.’ Napoleon gestured to the bloodied ground of the battlefield. ‘Have your men do a body count, then you send in your report to headquarters. I’m returning there now.’

‘Yes, sire.’
