Ikeda Terumasa vs Louis-Nicolas Davout

Ikeda Terumasa married Tokugawa Ieyasu's daughter, Tokuhime, becoming a son-in-law of the future shogun. This marriage cemented his loyalty to the Tokugawa clan and elevated his status among daimyo.

Terumasa fought for the Eastern Army under Tokugawa Ieyasu at Sekigahara. He commanded a large contingent and played a key role in the victory. After the battle, he was rewarded with the Himeji domain.

Terumasa oversaw the expansion and renovation of Himeji Castle, transforming it into the largest and most fortified castle in Japan. The project took nine years and established the castle as a symbol of Tokugawa power.

Terumasa participated in the Siege of Osaka, leading Tokugawa forces against the Toyotomi clan. His troops helped capture the outer defenses of Osaka Castle, contributing to the final defeat of the Toyotomi.

Davout commanded the III Corps on the right flank, holding off the main Austrian-Russian attack while Napoleon crushed the center. His corps marched 120 km in 48 hours to reach the battlefield. This victory destroyed the Third Coalition and established French dominance in Europe.

Davout's single corps of 26,000 men defeated the main Prussian army of 63,000 under the Duke of Brunswick. He used aggressive tactics and superior discipline to rout the Prussians. This victory, on the same day as Napoleon's victory at Jena, led to the collapse of Prussia.

Davout was appointed governor-general of the newly created Duchy of Warsaw. He organized the Polish army and administration, implementing French legal and military reforms. His efficient governance helped secure Polish support for Napoleon's campaigns.

Davout commanded the I Corps in the center of the French line, leading assaults on the Russian fortifications. He was wounded but continued to command. The battle was a tactical draw but a strategic disaster for Napoleon, as the Russians withdrew and later forced the French retreat.

Davout held Hamburg against a Prussian-Russian siege for over a year, using harsh measures including expelling civilians. He surrendered only after Napoleon's abdication. His defense was militarily competent but criticized for its brutality, tarnishing his reputation.

After Napoleon's abdication, Davout submitted to the Bourbon monarchy and was made a peer of France. He did not join Napoleon during the Hundred Days until ordered to do so by the king. This pragmatic decision allowed him to retain his titles and avoid execution.
