Napoleon took a deep breath and glared at his boots resting on the seat opposite.When he spoke it was with a bitter intensity that Berthier had never heard before. ‘God damn that coward Villeneuve to the most fiery pits of hell. We will never beat the British at sea now.’ He paused, and then continued in a low voice, ‘My plans for the invasion are finished. We must find another way to beat Britain. If we can’t defeat them on the battlefield, we must strangle their economy.’ His eyes glittered cruelly. ‘We must ruin them, and when their money has drained away and their people are starving they will beg us for peace, rather than face a revolution of their own.’

There was a brief silence as the carriage rumbled and slid along the muddy track, and then Berthier asked, ‘What do we do now, sire?’

‘Now?’ Napoleon nodded in the direction the carriage was heading. ‘Now we fix every thought on crushing our Austrian and Russian friends as ruthlessly and completely as possible.’

That night, as word of Villeneuve’s defeat spread through the army, there was a subdued atmosphere in the camp. Napoleon could not help being aware of it as he strode through the tent lines and attempted to raise the men’s morale by stopping to talk to them as they crowded round their fires.The temperature had dropped still further and every so often a light flurry of snowflakes swirled out of the dark heavens. The usual greetings were more muted, and Napoleon was conscious of conversation stopping as soon as men were aware of his approach. His dark mood over the defeat was made worse by the latest report from Murat.

His cavalry commander had barely been able to contain his excitement as he wrote to tell Napoleon that the road to Vienna was open. Murat had given orders for his corps to advance on the Austrian capital. As a result Kutusov was no longer being pursued, and according to further reports the Russians had crossed the Danube and were making good their escape along the northern bank. Now they would have time to gather their strength, and manoeuvre closer to their Austrian allies to combine their forces and face Napoleon on more equal terms.
