ON THIS DAY · 7 SEPTEMBER 1812
Borodino
7 Sep 1812 — Some 250,000 men and 70,000+ casualties: the bloodiest single day of war until 1916. Napoleon holds the field; the Russian army survives — which is what matters.
THE MOMENT IN CONTEXT
The invasion of Russia was built around a single expectation that failed. About 600,000 troops, many of them from allied or subject states, crossed the Niemen on 24 June 1812 so that Napoleon could trap the Russian armies in a decisive battle near the frontier. The Russians withdrew instead, whether by deliberate design or through the confusion of divided command, and every eastward march after that lengthened French supply lines and thinned the available forage. Typhus, dysentery, heat and desertion removed large numbers of men before the first major battle was even fought.
From Chapter 8 — 1812: The Russian Campaign of The Age of Revolutions, 1775–1848 (SEP 1812).

Then ask the room: Napoleon had studied Charles XII’s 1709 disaster in Russia and carried the history books on campaign. Why did knowing the precedent not save him? The argued answer is on the chapter page →
