As Napoleon's army reached Bobr, 50 kilometres from Borisov, he was informed that the bridge over the Berezina at Borisov had been destroyed. Napoleon also learned that a French cavalry brigade had discovered a place where the river might be crossed eight miles north of Borisov at the hamlet of Studienka. Although this was a place where an ice crossing could normally be made in November, a temporary thaw of the ice and the muddy banks made it necessary that bridges be constructed. Plans were made to build pontoon bridges. The commander of the pontoon bridge builders, General
Jean Baptiste Eblé, had disobeyed Napoleon's previous orders given during the withdrawal to destroy the equipment, forges, and tools necessary for building bridges. To draw the Russians' attention away from the vicinity of the crossing, numerous diversions were undertaken. On 25 November, bridge construction started in Studienka, even though numerous campfires belonging to the forces of Admiral Chichagov were observed across the river at Brili. The movements of French General
Nicolas Oudinot's corps and numerous rumours led the Russians to believe that Napoleon would either attack at Borisov and attempt to repair the bridge or lead his troops south of Borisov and cross the Berezina downstream. As a result, Chichagov made the decision to move the main body of his force south of Borisov to Szabaszeviki so that he could watch and patrol a 90kilometre stretch of the Berezina River. Russian General Chaplits and his force of approximately 3,000 men camped at Brili were ordered to move 15 kilometres south to support the Russian forces at Borisov. As a result, on the morning of 26 November, the French discovered that the Russians had abandoned their camp on the west bank. Forty French cavalry troopers made their way across the river and protected the crossing of 400 men in boats. This small force then secured the west bank so that the bridges could be completed. Meanwhile, neither of the Russian forces pursuing Napoleon from the rear were very aggressive and both remained substantial distances north and west of the Berezina River while the French bridged the river. This river was 20–30 metres wide and filled with drifting ice, but its banks were swampy, making the crossing extremely difficult. By 1 p.m. the smaller of the two bridges was complete and Oudinot began to lead his infantry of 7,000 men across the river and establish a defensive position to protect against the Russian forces to the south. Later that afternoon, the larger of the two bridges (for the artillery) was completed, but collapsed twice. Napoleon began to move his force across the Berezina in earnest. Overnight on 26–27 November, Russian General Chaplits became aware of the French crossing, consolidated his forces, and attempted to return to Brili to intercept the French. Chaplits's forces, however, were stopped well to the south of Brili by Oudinot's battalions. Also on the 27th, Chichagov began to move the main portion of his army back to Borisov when it became apparent that there was no French activity downstream. Chichagov, however, chose not to immediately move north to Brili inasmuch as his men were still in transit and not fully assembled. By midday of the 27th, Napoleon and his
Imperial Guard were across. One of the spans broke in the late afternoon, but the engineers had it repaired by early evening. The corps of
Marshal Davout and
Prince Eugene were able to cross before the day ended. The last unit on the eastern bank,
Marshal Victor's IX Corps was given the order to defend against the approach of Wittgenstein who had then reached Borisov. As a part of that operation, French General
Louis Partouneaux's 12th Division of the IX Corps suffered a great defeat, surrendering over 8,000 men when they were overwhelmed by Wittgenstein at Staroi-Borisov. On 28 November, the Russians coordinated their efforts and attacked Napoleon's on both sides of the river. On the west bank, Chaplits reinforced with additional infantry attacked the French forward positions and began to push Oudinot back to Brili. French
Marshal Ney took command when Oudinot was wounded and the Russian advance was stopped. Twenty-five thousand men engaged in a firefight that lasted into the night. Finally, French
General Doumerc led a cavalry charge of the
Cuirassiers, forcing the Russians back and ending the battle for the day. On the east bank of the river, Wittgenstein attacked Victor's IX Corps at 5 a.m. The French were pushed back in fighting that went on for eight hours. At 1 p.m., the Russians attained a position that enabled them to flank the French and rain down cannon fire on the bridges. The artillery bombardment fell largely upon the stragglers causing a human stampede as individuals rushed for the bridges or jumped into the cold river in an attempt to swim to the other side. The fighting and bombardment lasted for approximately four hours at which time the bridge engineers began working to clear a path for Victor's IX Corps to cross the river. At about 10 p.m. that evening, Victor's IX Corps made their crossing and three hours later the bridges were free of Napoleon's armed troops. The bridges were then available for the stragglers; however, despite encouragement, most of those who had fought so hard to get across the river during the bombardment chose to light their campfires and spend the night on the east bank. The next morning, the commander of the engineers, General Eblé had Napoleon's order to burn the bridges at 7 a.m. Eblé delayed the execution of that order until 8:30 a.m., at which time, tens of thousands of stragglers and their civilian companions were left behind. ...The unfortunate men who had not taken advantage of the night to get away had at the first appearance of dawn rushed on to the bridge, but now it was too late. Preparations were already made to burn it down. Numbers jumped into the water, hoping to swim through the floating bits of ice, but not one reached the shore. I saw them all there in water up to their shoulders, and, overcome by the terrible cold, they all miserably perished. On the bridge was a canteen man carrying a child on his head. His wife was in front of him, crying bitterly. I could not stay any longer, it was more than I could bear. Just as I turned away, a cart containing a wounded officer fell from the bridge, with the horse also. They next set fire to the bridge, and I have been told that scenes impossible to describe for horror then took place... Cossacks and Wittgenstein's troops closed in upon Studienka and took the stragglers on the east bank as prisoners. With the pontoon bridges gone, Wittgenstein had no means to cross the river and pursue Napoleon. On the west bank, Napoleon and his were on their way to Vilna. Chichagov sent Chaplits in pursuit of Napoleon but the French had destroyed three successive bridges across the Gaina swamp between Brili and the Zembin Road leading to Vilna. The swamp could not be crossed without the bridges. Napoleon had escaped. The battle at the Berezina River was over. ==Casualties==
