escaped. The battle at the Berezina River was over. Casualties Author David G. Chandler wrote in "The Campaigns of Napoleon" Aftermath The immediate result of the battle of Berezina had been simple: the French retreat went on, the Russian Army followed. The long-term result of the battle had been inconclusive. Although it had been a Russian tactical victory by definition as the losses of the "defeated" outweighed those of the "victor", the victorious Russian force failed to meet its original objectives. Indeed, despite enormous losses, Napoleon was in a position to claim a strategic victory, having snatched what was left of his army from a seemingly unavoidable catastrophe. There would be no large military confrontation for the rest of the retreat, although the incessant harassment of Russian Cossacks and the weather continued to take a toll on the surviving members of the French army. The losses had been extraordinary. It is estimated that 20–30,000 French combatants became casualties. "To the number of the slain in action must be added probably as many as 30,000 non-combatants." The Guard, which had not come into action at all, lost about 1,500 men out of 3,500. Much, however, had been saved. Napoleon, his generals, 200 guns, the war chest, much of the baggage, and thousands of officers and veteran soldiers had escaped. Overall, approximately 40,000 members of Napoleon's army were saved. Without this core of experienced men, Napoleon could not have rebuilt his armies for the battles of the War of the Sixth Coalition. According to author Andrew Zamoyski: The next two days were, according to some, among the worst of the entire retreat[...]no fallen horse or cattle remained uneaten, no dog, no cat, no carrion, nor indeed, the corpses of those who died of cold and hunger. Napoleon left his army on 5 December at Vilna. The temperatures dropped to -33.75 ℃ on 8 December and the number of combatants was down to 4,300. On 14 December the rest of the French main army crossed the Niemen. 36,000 French prisoners of the Grande Armée were taken by the Cossacks between 1–14 December. The only troops that had remained were the flanking forces (43,000 under Schwarzenberg, 23,000 under Macdonald), about 1,000 men of the Guard and about 40,000 stragglers. No more than 110,000 were all that was left from 612,000 (including reinforcements) that had entered Russia. The Russian losses may be about 250,000 men.
