🏯Sengoku Japan: The Unification1573

Battle of Mikatagahara

Takeda Shingen, marching toward Kyoto with the finest cavalry in Japan, drew Ieyasu's smaller garrison force out of Hamamatsu Castle onto the open plain of Mikatagahara and destroyed it comprehensively. Ieyasu fled back to his castle in such disarray that, by his own later account, he soiled himself in the saddle — and, on arrival, deliberately left the gates open and lit bonfires, a bluff so audacious that the pursuing Takeda scouts suspected an ambush and withdrew.

The one clean defeat any of the eventual unifiers suffered in a major pitched battle, and Ieyasu kept a portrait of his own humiliated, terrified face painted afterward, reportedly to remind himself never to be so reckless again. Shingen's death from illness a few months later, on the march, removed the one man capable of beating Nobunaga's alliance outright — Ieyasu's survival here was closer to accident than victory.

⚔️📍 Mortefontaine, France1801

Convention of Mortefontaine — U.S.-France Quasi-War Ends

The United States and France ratified the Convention of Mortefontaine, ending the undeclared naval war (Quasi-War) that had been fought in the Caribbean since 1798. The treaty abrogated the Franco-American alliance of 1778.

The Quasi-War was America's first naval conflict and proved that the young U.S. Navy could fight effectively; it built the naval tradition that would defend American commerce for generations.

Outcome

Quasi-War ends; Franco-American alliance dissolved

The Russo-Japanese War1905

Battle of Sandepu

In the depths of a Manchurian winter, General Gripenberg's Second Manchurian Army launched a surprise offensive on the Japanese left flank at Sandepu. The attack initially achieved surprise and penetrated Japanese lines before Kuropatkin, fearing overextension and a Japanese counterattack elsewhere, halted the offensive just as it approached a breakthrough. Gripenberg, furious at the lost opportunity, resigned his command and returned to Russia, where he publicly blamed Kuropatkin for squandering the best Russian offensive opportunity of the war.

Sandepu was the last serious Russian offensive of the war. Kuropatkin's decision to halt an attack that had broken through Japanese defenses epitomized his paralyzing caution and left Russia's armies demoralized heading into the decisive Battle of Mukden.

Algerian War of Independence1961

OAS Terror Campaign

The Organisation armée secrète (OAS), formed by former French military officers and pied-noir extremists, launched a terror campaign to prevent Algerian independence. The OAS carried out bombings, assassinations, and massacres targeting Muslim Algerians, French liberals, and even attempted to assassinate de Gaulle himself at Petit-Clamart in August 1962. The campaign killed approximately 2,788 people and drove the mass exodus of pieds-noirs from Algeria.

The OAS's campaign of indiscriminate terror against Muslim civilians and their scorched-earth destruction of infrastructure as they departed accelerated the pied-noir exodus and poisoned the transition to independence. The OAS represented the final, violent death throes of French Algeria.
