On 7 September the French caught up with the Russian army which had dug itself in on hillsides before a small town called Borodino, seventy miles west of Moscow. The battle that followed was the largest and bloodiest single-day action of the Napoleonic Wars, involving more than 250,000 soldiers and resulting in 70,000 casualties. The French gained a victory, but at the cost of 49 general officers and thousands of men. The Russian army was able to extricate itself and withdrew the following day, leaving the French without the decisive victory Napoleon sought.[12]
Napoleon entered Moscow a week later. In another turn of events the French found puzzling, there was no delegation to meet the Emperor. The Russians had evacuated the city, and the city's governor, Count Fyodor Rostopchin, had ordered the city to be burnt.[13] Napoleon's hopes had been set upon a victorious end to his campaign, but victory in the field did not yield him victory in the war. The loss of Moscow did not compel Alexander I to sue for peace, and both sides were aware that Napoleon's position grew worse with each passing day. Napoleon stayed on in Moscow looking to negotiate a peace, his hopes fed in part by a disinformation campaign informing the Emperor of supposed discontent and fading morale in the Russian camp. After staying a month Napoleon moved his army out southwest toward Kaluga, where Kutusov was encamped with the Russian army.
The French advance toward Kaluga was checked by a Russian corps. Napoleon tried once more to engage the Russian army for a decisive action at the Battle of Maloyaroslavets. Despite holding a superior position, the Russians retreated following a sharp engagement, confirming that the Russians would not commit themselves to a pitched battle.[14] His troops exhausted, with few rations, no winter clothing, and his remaining horses in poor condition, Napoleon was forced to retreat. He hoped to reach supplies at Smolensk and later at Vilnius. In the weeks that followed the Grande Armée starved and suffered from the onset of the Russian Winter. Lack of food and fodder for the horses, hypothermia from the bitter cold and persistent attacks upon isolated troops from Russian peasants and Cossacks led to great losses in men, and a general loss of discipline and cohesion in the army. When the remnants of Napoleon's army crossed the Berezina River in November, only 27,000 fit soldiers remained; the Grand Armée had lost some 380,000 men dead and 100,000 captured.[15] Following the crossing of the Beresina Napoleon left the army, after much urging from his advisors and with the unanimous approval of his Marshals.[16] He returned to Paris by carriage and sledge to protect his position as Emperor and to raise more forces to resist the advancing Russians. The campaign effectively ended on 14 December 1812, not quite six months from its outset, with the last French troops leaving Russian soil.
