🏯Sengoku Japan: The Unification1615
Siege of Osaka: The Summer Campaign
With Osaka Castle's moats filled in, the Toyotomi forces had to fight in the open at Tennōji rather than behind walls. Sanada Yukimura led a desperate final charge that broke through the Tokugawa lines and came within a hundred metres of Ieyasu's own command post — the closest anyone ever came to killing him in battle — before being overwhelmed and killed. The castle fell that day; Hideyori and his mother Yodo-dono, Nobunaga's niece and Hideyoshi's consort, killed themselves inside it as it burned. Hideyori's young son, the last direct Toyotomi heir, was found and executed.
The end of the Toyotomi line and, with it, the last serious military resistance to Tokugawa authority. It closes the unification cycle exactly where it began — with the destruction of an entire clan and the killing of its heirs, the method Nobunaga and Hideyoshi had themselves used on the Azai, the Takeda, and the Hōjō, now turned by Ieyasu on Hideyoshi's own son. What followed was two hundred and fifty years without a major civil war, purchased by finishing the Sengoku period's logic all the way to its end.

⚔️📍 Cold Harbor, Virginia1864
Battle of Cold Harbor — Grant's Bloodiest Hour
Union General Grant ordered a frontal assault on heavily fortified Confederate positions at Cold Harbor. In under an hour, the Union Army suffered 7,000 casualties — men who had written their names on paper and pinned them to their backs before the assault, knowing they would die.
Cold Harbor was Grant's greatest tactical blunder and so disturbed him that he later wrote it was the only battle he wished he had not fought; but Grant continued the campaign.
Outcome
Confederate defensive victory; 7,000 Union casualties in one hour
