Round 2

Battle of Manzikert

Battle of Manzikert · 1071 · Medieval

Why there: Manzikert sat on Byzantium's exposed eastern frontier in Armenia, the mountainous gateway between the Anatolian heartland and the steppe corridors through which nomadic invaders funneled toward the empire's rich highlands.

Why then: By 1071 the Seljuk Turks had recently surged out of Central Asia into the Islamic world, while Byzantium was weakened by internal court rivalries and a reliance on unreliable mercenaries, so a single lost battle could unravel decades of frontier defense.

• This battle saw a Byzantine emperor defeated and captured by a Seljuk sultan.
• The defeat opened the highland peninsula to Turkish migration and is often seen as a turning point in Byzantine decline.
• It occurred near a town in the eastern highlands that today lies in Turkey.

Round 3

Battle of Red Cliffs

Battle of Red Cliffs · 208 · Antiquity

Why there: The battle unfolded along the Yangtze, the wide southern river that formed a natural defensive barrier where the southern warlords could exploit their naval strength and force Cao Cao's northern, land-based army to fight on unfamiliar water.

Why then: With the Han dynasty's central authority collapsed in 208, rival warlords carved up the realm, and Cao Cao's bid to conquer the south before consolidation could set in made this the decisive moment that fixed the coming Three Kingdoms division.

• The Battle of Red Cliffs (208 CE) saw the allied forces of Sun Quan and Liu Bei defeat the much larger army of Cao Cao.
• Cao Cao's ships were reportedly linked together, making them vulnerable to a devastating fire attack.
• The battle paved the way for the Three Kingdoms period and is dramatized in the novel 'Romance of the Three Kingdoms.'

Round 4

Battle of Lützen

Battle of Lützen · 1813 · 19th Century

Why there: Lützen sits on the plains of Saxony astride the roads to Leipzig, a strategic crossroads where Napoleon's westward-based forces had to block the Russo-Prussian advance to keep his grip on the German states of the Confederation of the Rhine.

Why then: Coming right after the destruction of the Grande Armée in the 1812 Russian winter, spring 1813 was the moment Prussia switched sides and the coalition pressed while Napoleon scrambled to field hastily raised conscripts before his rebuilt army could mature.

• This battle opened Napoleon's German campaign of the Sixth Coalition (1813).
• Marshal Bessières was killed by a cannonball at Rippach the day before the battle, leaving the French short of cavalry leadership.
• The French held the field but lacked the cavalry to pursue.

Round 5

Battle of Panipat

Battle of Panipat · 1526 · Early Modern

Why there: Panipat sits on the flat plain north of Delhi astride the classic invasion corridor into the Gangetic heartland, forcing any power entering India through the northwestern passes to fight for the road to the capital there.

Why then: By 1526 gunpowder field artillery and matchlock tactics had spread from the Ottoman world into Central Asia, letting a small mobile force like Babur's defeat far larger cavalry armies that older sultanates still relied on.

• This battle (1526) saw the invader defeat the reigning sultanate's ruler on a plain north of the capital.
• The victory established a new empire that ruled northern India for centuries.
• Effective use of gunpowder artillery was decisive against the larger army.
