🏯Sengoku Japan: The Unification1582

The Honnō-ji Incident

Ordered to march west to reinforce a campaign, Akechi Mitsuhide instead turned his roughly 13,000 troops toward Kyoto, where Nobunaga was lodging with only a small guard at the temple Honnō-ji, en route to the same campaign. Akechi's men surrounded the temple before dawn. Nobunaga, realising the situation was hopeless, is said to have fought briefly with bow and spear before withdrawing into the burning building and taking his own life, ensuring his enemy could never produce his head as a trophy.

The single most consequential assassination in Japanese history and, four hundred and thirty years on, still one whose exact motive is unresolved — resentment, ambition, fear of demotion, and conspiracy theories involving Hideyoshi or the imperial court have all been argued. Whatever Akechi intended, he had not secured the loyalty of Nobunaga's other generals, and his coup collapsed within thirteen days.

⚔️📍 Vitoria, Spain1813

Battle of Vitoria — Wellington Defeats France in Spain

Wellington's Anglo-Portuguese-Spanish army decisively defeated Joseph Bonaparte's French army at Vitoria, capturing the entire French treasury and forcing France to abandon Spain. The retreating French army became a disorganized mob.

Vitoria effectively ended the Peninsular War and forced Napoleon to divert troops from Germany to deal with Spain — a major contribution to his final defeat in 1814.

Outcome

Allied victory; French expelled from Spain

Casualties

15,000
