Round 1

Battle of Chaldiran

1514 · Early Modern

Why there: The plain of Chaldiran lay on the contested eastern Anatolian frontier near Lake Urmia, the natural buffer zone between the expanding Ottoman Empire and the young Safavid state, making it the gateway through which either power had to advance to strike the other's heartland.

Why then: By 1514 the Ottomans had integrated field artillery and matchlock-armed janissaries into their armies, while the Safavids still relied on traditional Qizilbash cavalry, so this was the moment gunpowder technology decisively tipped the balance against horse-borne elites.

• The Battle of Chaldiran (1514) was an Ottoman victory over Safavid Persia under Shah Ismail I.
• Ottoman artillery and janissary firearms overwhelmed the Safavid Qizilbash cavalry.
• The battle established a long-contested border between the Ottoman and Persian empires.

Round 2

Battle of Nedao

454 CE · Antiquity

Why there: The Pannonian plain along the Nedao river was the grassy heartland where the Hunnic empire had settled its horse herds and subject Germanic peoples, so the revolt naturally erupted on the very lowlands the Huns used as their base of power.

Why then: The death of Attila in 453 removed the singular leader who held the confederation together, and with his sons splitting the subject tribes among themselves like property, the resentful Gepids and other vassals seized that succession crisis as the moment to break free.

• The Battle of Nedao (454 CE) followed the death of Attila the Hun the previous year.
• A coalition led by the Gepid king Ardaric defeated Attila's sons, ending Hunnic dominance in Central Europe.
• It was fought in Pannonia, in the region of modern Serbia.

Round 3

Battle of Peleliu

1944 · 20th Century

Why there: Peleliu sat in the Palau island chain guarding the eastern approaches to the Philippines, and its Japanese airfield was seen as a threat to General MacArthur's planned invasion, making the tiny coral island a target for American amphibious assault.

Why then: By 1944 the American island-hopping campaign was driving toward the Philippines, and Japan, having lost hope of stopping landings on the beaches, had shifted to a new doctrine of attrition from fortified inland caves that turned such islands into prolonged killing grounds.

• U.S. Marines fought entrenched Japanese forces on this island.
• Japanese defenders used a network of caves and a ridge nicknamed 'Bloody Nose Ridge.'
• The high casualties relative to its strategic gain made it one of the war's most controversial battles.

Round 5

Treaty of Brétigny

1360 · Medieval

Why there: The treaty was signed at Brétigny, a village near Chartres, because it lay in the French heartland where the campaigning English army had advanced, making it a convenient neutral spot to negotiate a pause between the two crowns.

Why then: The moment came in 1360 because the French king John II had been captured at Poitiers in 1356, and years of ruinous war left France desperate enough to trade vast Aquitanian lands and a huge ransom for peace.

• The Treaty of Brétigny (1360) was signed near Chartres, ending the first phase of the Hundred Years' War.
• Edward III renounced his claim to the French crown in return for sovereignty over Aquitaine and a huge ransom for King John II.
• The peace was fragile and fighting resumed within a decade.
