Round 1

Battle of Kursk

1943 · 20th Century

Why there: The front line around Kursk had formed a huge westward salient into German-held territory, tempting the Wehrmacht to pinch off the bulge from north and south while giving the Soviets a predictable target to fortify in depth.

Why then: By mid-1943 the Germans had lost the strategic initiative after Stalingrad and gambled on new heavy tanks to reverse it, while a forewarned, industrially resurgent Soviet Union had time to build layered defenses and marshal reserves for the counterblow.

• This is considered the largest tank battle in history.
• It marked the end of Germany's strategic offensive capability on the Eastern Front.
• The fighting near Prokhorovka involved hundreds of tanks clashing at close range.

Round 2

Battle of Lissa

1866 · 19th Century

Why there: The island of Lissa (Vis) guarded the Austrian-held eastern Adriatic, so Italy's fleet sought to seize it as a stepping-stone against Austria's coast, drawing the defending squadron to intercept them there.

Why then: The 1860s saw new steam-powered ironclads replace wooden sailing ships just as Italian unification and the Austro-Prussian War of 1866 pitted these navies against each other, making it the first fleet battle to test armored steam warships in combat.

• This was the Battle of Lissa, fought in July 1866 in the Adriatic during the Austro-Prussian/Third Italian War.
• Admiral Wilhelm von Tegetthoff's Austrian fleet defeated a larger Italian fleet, ramming and sinking the Re d'Italia.
• It was the first major fleet action between ironclad warships and revived faith in the naval ram for decades.

Round 4

Battle of Red Cliffs

208 CE · 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 5

Battle of Hunayn

630 CE · Medieval

Why there: Hunayn was a narrow valley on the route between Mecca and Ta'if, where the powerful Hawazin and Thaqif tribes could stage an ambush in terrain that neutralized a larger force and channeled the fighters into a killing zone.

Why then: With Mecca just taken and the new Muslim movement now dominant in the Hijaz, the surrounding nomadic confederations mobilized in 630 to check its rise before it consolidated control over Arabia's tribes and trade.

• The Battle of Hunayn (630 CE) followed the conquest of Mecca.
• Muslim forces, initially ambushed by the Hawazin and Thaqif tribes, rallied to win.
• It was fought in a valley near Mecca in the Hejaz region of western Arabia.
