Napoleon pulled the thick fur robe more closely about his shoulders as he stared into the fireplace. A servant had built the fire up before retiring and leaving him alone in the study.That had been over an hour ago, and the split logs had long since burned through. The charred timber was gilded with bright orange specks that pulsed slowly amid the slender fingers of flame flickering up from the heart of the fire. Outside, the wind moaned round the castle as the blizzard that had begun at dawn continued into the dusk, blanketing the city in a thick mantle of white snow. Winter gripped the land and across Poland the men of the Grand Army huddled in their billets and only ventured abroad to search for food and firewood, or when required for patrol and sentry duties.

As the previous year had come to an end the Emperor had finally sent his army into winter quarters, before exhaustion and a sharp decline in morale caused it to fall apart. Despite the victories at Jena and Auerstadt and the subsequent pursuit of the remnants of the Prussian army until its almost complete destruction, the Prussians had not surrendered. Even as Marshal Davout had led his corps in triumph through the streets of Berlin the Prussian King, Frederick William, had fled east to join his Russian allies and continue the war against France. All that was left of his army was one rag-tag column scraped together from the survivors, barely a match for a single corps of the Grand Army. Yet, Napoleon knew, the Russians were massing formidable numbers of men to confront the French army once the worst of the winter had passed. Or so he had thought until the first reports of Russian movements had reached imperial headquarters. It seemed that the Russian soldiers were injured to the effects of winter and were already advancing towards the French outposts.

Napoleon idly stroked his chin as he considered the situation. Berthier had updated his notebooks the previous night, and examining them the following morning Napoleon had been shocked to learn how his army had been ravaged by the onset of winter. Almost half of the men were absent from their units as they ranged across the frozen countryside stealing food and looting whatever valuables they discovered in the villages and estates surrounding Warsaw. Discipline was breaking down and already there had been reports of men killing officers and sergeants who had attempted to hold them back from committing the worst excesses.
