July 2 in Military History — On This Day

Battle of Yamazaki

Hideyoshi was campaigning against the Mōri clan in the west when news of Nobunaga's death reached him. He concluded an extraordinarily fast peace with the Mōri, concealed his lord's death from them just long enough to withdraw safely, and marched his army roughly 200 kilometres back toward Kyoto in an eight-day forced march still celebrated as one of the fastest large-unit movements in premodern military history. He caught Akechi Mitsuhide, whose coalition had not solidified, at Yamazaki and broke his army in a few hours.

The Chūgoku Ōgaeshi — the 'great return from Chūgoku' — is the single act that made Hideyoshi rather than any other Oda general the heir to Nobunaga's project. Akechi fled the field and was killed by bandits or peasants within days; his thirteen-day reign is proverbial in Japanese for a fleeting, illegitimate rule. Hideyoshi's speed here won him a headstart none of Nobunaga's other retainers could match.

Battle of Nieuwpoort

Sent by the States-General on a campaign he thought reckless, Maurice found himself trapped on the beach at Nieuwpoort with the Spanish army between him and home and the sea at his back. He had no choice but to fight the tercios in the open — the one thing the Dutch never did. His drilled, salaried, volley-firing infantry beat them.

The first time in eighty years that a Dutch army defeated a Spanish army in a pitched open battle, and the vindication of everything Maurice had rebuilt: standardised weapons, engineering, regular pay, and above all the countermarch — ranks firing and rotating so the volleys never stopped. Strategically Nieuwpoort achieved nothing and Maurice went straight home. Militarily it announced that the tercio's century was ending, and every army in Europe started copying the drill book.

Battle of Marston Moor

The largest battle fought on English soil during the war. The combined Parliamentary and Scottish army of some 27,000 confronted Prince Rupert's 18,000 Royalists on the flat moorland west of York. As evening approached and a cavalry engagement seemed delayed, Parliamentary forces launched a surprise attack across the whole front. Cromwell's cavalry routed Rupert's horsemen on the left, then — uniquely — rallied and turned to strike the Royalist infantry in the flank and rear. Within two hours the Royalist army was shattered.

Marston Moor destroyed Royalist power in the North of England permanently. The Earl of Newcastle, humiliated, took ship for the Continent and never returned. Prince Rupert's legend was badly dented. Most importantly, it was the battle that made Cromwell's national reputation: his disciplined cavalry, which unlike Rupert's horse rallied after their charge rather than pursuing fleeing enemies, proved the decisive factor. A Scottish officer reported that Cromwell had said 'God made them as stubble to our swords' — and the phrase captured something real about his iron Calvinist faith and military genius combined.

Battle of Lauffeld

Saxe lured Cumberland into attacking a village complex bristling with French infantry, bled the allied army white in brutal house-to-house fighting, then unleashed his cavalry reserve to complete the rout. Cumberland's army was shattered; only a rearguard action by British cavalry prevented total annihilation.

Lauffeld was Saxe's final and perhaps most complete victory. After it, Britain, the Netherlands, and Austria were militarily exhausted and had lost leverage for any favorable peace terms. The path to Aix-la-Chapelle was now open — France negotiated from a position of total battlefield supremacy.

⚔️📍 Gettysburg, Pennsylvania1863

Battle of Gettysburg — Day 2: Little Round Top

The second day of Gettysburg featured Confederate assaults on both Union flanks — Devil's Den, the Peach Orchard, and Little Round Top, where a bayonet charge by the 20th Maine under Joshua Chamberlain repelled the Confederate attack that might have turned the Union line.

The holding of Little Round Top preserved the Union position and set up the failed Pickett's Charge on Day 3, making Day 2 arguably the decisive day of the battle.

Outcome

Union holds key positions; Confederate attacks fail

Casualties

20,000
