Round 1

Wounded Knee Massacre

Wounded Knee Massacre · 1890 · 19th Century

Why there: The creek lay within the Pine Ridge Reservation in South Dakota, where Lakota bands had been confined onto shrinking government-controlled land after being pushed off their traditional plains hunting grounds.

Why then: By 1890 the frontier was nearly closed, the bison exterminated, and desperate reservation communities embraced the Ghost Dance revival, which alarmed the U.S. Army into a disarmament campaign that turned deadly.

• The Wounded Knee Massacre occurred in December 1890 in South Dakota.
• Around 250-300 Lakota, including many women and children, were killed by the U.S. 7th Cavalry.
• It followed the rise of the Ghost Dance movement and the killing of Sitting Bull.

Round 2

Siege of Constantinople

Siege of Constantinople · 1204 · Medieval

Why there: Constantinople straddled the Bosphorus at the crossroads of Europe and Asia, its immense wealth and control of Black Sea and Mediterranean trade making it both the prize the crusaders coveted and a target reachable by the Venetian fleet ferrying them.

Why then: By 1204 the Fourth Crusade was bankrupt and indebted to Venice, and a Byzantine dynastic dispute offered a pretext, allowing commercial ambition and a weakened, faction-ridden empire to redirect the expedition against its own Christian ally.

• This 1204 event by the Fourth Crusade ended with the brutal sack of the Eastern empire's capital.
• The crusaders established the Latin Empire, fracturing the Byzantine state for decades.
• The city is modern Istanbul, Turkey.

Round 3

Battle of Gangut

Battle of Gangut · 1714 · Early Modern

Why there: The Hanko (Gangut) peninsula's narrow, rocky coastal waters off Finland forced the Swedish sailing fleet into a chokepoint where shallow, windless channels neutralized their advantage, and controlling this passage was key to Russia's advance toward the Åland Islands and Stockholm.

Why then: By 1714 Peter the Great's decade of forced modernization during the Great Northern War had built Russia a galley fleet from nothing, so Russia could finally challenge Sweden's Baltic naval dominance just as the tide of the war was turning.

• The Battle of Gangut (Hanko, 1714) was the Russian navy's first major naval victory.
• Russian galleys defeated a Swedish squadron off the Hanko Peninsula in present-day Finland.
• Calm conditions neutralized the Swedish sailing ships, letting the oared Russian galleys prevail.

Round 5

Battle of Okinawa

Battle of Okinawa · 1945 · 20th Century

Why there: Okinawa lay just 340 miles from Japan's main islands, making it the essential staging base and airfield network the Allies needed to launch a final invasion of the Japanese home islands.

Why then: By 1945 the U.S. island-hopping campaign had rolled back Japan's Pacific empire to its doorstep, so seizing the last major outpost before the homeland became the logical—and bloodiest—next step.

• This was the largest amphibious assault of the Pacific War.
• Kamikaze attacks sank or damaged many Allied ships during the campaign.
• The enormous casualties influenced the decision to use atomic weapons rather than invade Japan.
