Battle of Borodino, 1812 (1822)

Louis Francois Lejeune: Battle of Borodino, 1812

Lejeune (1775-1848) was a general as well as an artist. His name is one of those engraved on the Arc de Triomphe.

The Battle of Borodino was in many ways the climax of Napoleon's invasion of Russia. It was the single bloodiest day of that war, involving over a quarter of a million troops overall and resulting in 70,000 casualties - a bloody affair indeed. Technically it was a French victory - the Russian army withdrew - but by failing to pursue and finish them off, Napoleon planted the seeds of his own ultimate defeat. The Wikipedia page has an exhaustive description and analysis of the engagement.

Napoleon’s bivouac on the eve of Austerlitz (1808)

Louis-François Lejeune: Napoleon’s bivouac on the eve of Austerlitz, 1 December 1805

The Battle of Austerlitz was probably Napoleon's single greatest military victory. Lejeune illustrates the Emperor’s bivouac in the Moravian plains on the eve of the battle. Napoleon, at center (of course) consults with his generals while the soldiers forage and make camp. Other paintings, to be featured later, depict the battle itself - a bloody 9-hour affair.

Battle of the Pyramids (1808)

Louis-François Lejeune: Battle of the Pyramids

The so-called Battle of the Pyramids took place on July 21, 1798, between Napoleon's French forces and the Egyptians. This decisive French victory, seeming to pave the way for French domination of the Middle East, came to nothing as a mere 10 days later Admiral Nelson defeated Napoleon's fleet in the Battle of the Nile.

Battle of Marengo (1801-02)

This is Louis-François Lejeune's painting of The Battle of Marengo.

The Battle of Marengo took place in Italy's Piedmont region in June 1800; the combatants were Napoleon's forces on one side and the Austrians on the other. The French forces emerged victorious, consolidating Napoleon's political position at home.

The artist, Louis-François Lejeune, was also a soldier who took part in this battle and many others throughout the Napoleonic era. He participated in the Spanish campaign (the so-called Peninsular War), the Battles of Marengo and Austerlitz, and the ill-fated Russian campaign (during which Lejeune deserted his post due to frostbite and was arrested on orders from Bonaparte himself). He redeemed himself during the Battle of Lützen and continued military service until 1813. During the German campaign of 1806 he met the inventor of lithography and played a major role in introducing this method to France.
