Round 1

Battle of Bapheus

Battle of Bapheus · 1302 · Medieval

Why there: Bapheus lay in Bithynia on the Asian shore near Nicomedia, the frontier zone where Byzantine control was thinnest and directly across the straits from Constantinople, making it the natural pressure point for a rising Anatolian power pushing toward the imperial capital.

Why then: By 1302 the Byzantine Empire, weakened after the 1204 Latin sack and stretched thin defending its European lands, could no longer garrison its Anatolian frontier, leaving a vacuum that the mobile Turkish ghazi bands under Osman were positioned to exploit.

• The Battle of Bapheus (1302) was the first major victory of Osman I, founder of the Ottoman dynasty.
• Ottoman forces defeated a Byzantine army near Nicomedia in northwestern Anatolia.
• It marked the emergence of the Ottoman emirate as a serious threat to Byzantium and the gradual loss of Byzantine Bithynia.

Round 3

Battle of Lissa

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

Operation Ten-Go

Operation Ten-Go · 1945 · 20th Century

Why there: The Yamato sortied into the East China Sea toward Okinawa because that island was the last defensive barrier before the Japanese home islands, and losing it would open Japan itself to invasion.

Why then: By April 1945 Japan's shattered navy and near-total loss of air cover meant surface ships had no fuel or protection left, so a one-way suicide mission was all a desperate late-war command could mount.

• This was the last major Japanese naval operation of the war.
• The battleship Yamato was sunk by U.S. carrier aircraft en route to Okinawa.
• Most of the crew, including the fleet commander, were lost.

Round 5

Battle of Lützen

Battle of Lützen · 1632 · Early Modern

Why there: Lützen sits on the flat plains of Saxony in central Germany, a strategic crossroads where Swedish and Imperial armies maneuvered for control of the Protestant heartland and its supply routes during the Thirty Years' War.

Why then: By 1632 Sweden's Gustavus Adolphus had intervened in the sprawling religious-political war engulfing the Holy Roman Empire, deploying newly modernized mobile artillery and combined-arms tactics that made his campaign the decisive Protestant counteroffensive of that decade.

• The Protestant king's army held the field but he was killed in the battle (1632).
• It was fought in the same region as his great victory of the previous year.
• His death deprived the Protestant alliance of its most capable military leader.
