Round 1

Sand Creek massacre

1864 · 19th Century

Why there: The Cheyenne and Arapaho camped along Sand Creek in eastern Colorado Territory because the discovery of gold nearby in 1858 had flooded their treaty lands with settlers, pushing tribes onto marginal prairie while U.S. authorities coveted the corridor to the Rockies.

Why then: The Civil War had placed the frontier under aggressive volunteer militias led by ambitious commanders like Colonel Chivington, who exploited wartime fears and lax oversight to strike a village even after its leaders sought peace at Fort Lyon.

• This was the Sand Creek Massacre of November 1864 in Colorado Territory.
• Colonel John Chivington's troops attacked a Cheyenne and Arapaho village led by Chief Black Kettle, who had been promised protection.
• Congressional investigations condemned the killings, but no one was ever punished.

Round 3

Attack on Pearl Harbor

1941 · 20th Century

Why there: Pearl Harbor in Hawaii was the forward-deployed home of the U.S. Pacific Fleet, whose battleships and carriers were the only force capable of blocking Japanese expansion across the Pacific, making the harbor the decisive target.

Why then: By 1941 U.S. oil embargoes threatened to strangle Japan's war economy, while newly matured carrier aviation gave Japan the long-range striking power to attempt a knockout blow before America could rearm.

• This was the attack on Pearl Harbor, Hawaii, on 7 December 1941.
• Imperial Japan's strike brought the United States into the Second World War.
• President Franklin D. Roosevelt called it 'a date which will live in infamy.'

Round 4

Siege of Nicaea

1097 · Medieval

Why there: Nicaea sat on the main overland road into Anatolia and guarded a lakeside crossroads near Constantinople, making it the Seljuk capital the crusaders had to take first to march deeper east while the lake let the Byzantines cut off resupply.

Why then: The Seljuk defeat of Byzantium at Manzikert in 1071 left Anatolia contested, prompting the emperor's appeal to the West that Pope Urban II answered in 1095, launching the armed pilgrimage that reached Nicaea in 1097.

• This was an early success of the First Crusade.
• The city surrendered to the Byzantine emperor rather than to the crusaders, frustrating them.
• It sits beside a lake in northwestern Anatolia, in modern Turkey.

Round 5

Battle of Blenheim

1704 · Early Modern

Why there: The battle was fought along the Danube in Bavaria because the river was the invasion highway toward Vienna, and stopping the Franco-Bavarian advance there was the only way to shield the Habsburg emperor's threatened capital.

Why then: By 1704 the War of the Spanish Succession pitted a grand alliance against Louis XIV's overreaching France, and improved roads, logistics, and Marlborough's disciplined professional army made a rapid 250-mile march and decisive pitched battle feasible in a way earlier eras could not sustain.

• The Battle of Blenheim (1704) was a turning point in the War of the Spanish Succession.
• The Duke of Marlborough and Prince Eugene of Savoy defeated the French and Bavarians on the Danube in Bavaria.
• It ended the threat to Vienna and gave the name 'Blenheim' to Marlborough's palace.
