The Battle of Valutino (also called the battle of Lubino) took place on 19 August 1812 near Valutino[ru] and Lubino[ru], between a corps of French and allied troops led by Marshal Ney, about 35,000 strong, and a strong rear-guard of General Barclay de Tolly's Russian army of about 25,000, commanded by the general himself. The Russians were strongly posted in marshy ground, protected by a small stream, about 20 kilometres (12 mi) east of Smolensk. The French, attacking resolutely, captured the Russian position in the face of considerable physical obstacles; the Russian army, however, did not intend to determinately defend this position, because at the time of the battle it was in a general retreat deep into the territory as part of a scorched earth strategy.
