Not enough completed runs on this day to report an average without singling out an individual player’s score — we publish one from 5 finishers up.

Round 1

Treaty of Brétigny

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.

Round 2

Battle of Naissus

Battle of Naissus · 268 · Antiquity

Why there: Naissus (modern Niš) sat on a strategic Balkan road junction just south of the Danube frontier, making it the natural chokepoint where Gothic raiders pushing inland could be intercepted before reaching the empire's Aegean and Anatolian heartlands.

Why then: The mid-3rd-century Crisis had weakened Rome's overstretched Danube defenses and invited mass Gothic incursions, but the rise of capable Illyrian soldier-emperors like Claudius II finally organized the mobile field armies needed to crush the invaders and restore the frontier.

The Battle of Naissus (268/269 CE) was a major Roman victory over the Goths during the Crisis of the Third Century.
It is credited to Emperor Gallienus and/or his successor Claudius II, who took the title 'Gothicus.'
The defeat blunted the Gothic invasions and helped preserve the empire's Balkan/Danubian frontier.

Round 3

Gadsden Purchase

Gadsden Purchase · 1853 · 19th Century

Why there: The flat, low-elevation desert south of the Gila River offered the only practical grade for a transcontinental railroad avoiding the Rockies, and it still lay in Mexican hands after the 1848 border was drawn just north of it.

Why then: Coming right after the Mexican-American War and amid the railroad boom, the U.S. was flush with expansionist ambition and eager to build a southern rail line, while a cash-strapped postwar Mexico was willing to sell for ten million dollars.

The Gadsden Purchase (1853) transferred land from Mexico to the United States for $10 million.
It secured territory for a planned southern transcontinental railroad route.
It established most of the present-day border of Arizona and New Mexico with Mexico.

Round 4

Battle of Rocroi

Battle of Rocroi · 1643 · Early Modern

Why there: Rocroi sat on France's vulnerable northeastern frontier along the Ardennes, guarding an invasion corridor from the Spanish Netherlands, so a Spanish army striking toward Paris had to be intercepted at this fortified border town.

Why then: By 1643 the rigid Spanish tercio squares had fallen behind newer flexible linear tactics and better-coordinated artillery, while Spain, exhausted by the Thirty Years' War and internal revolts, could no longer sustain the dominance it had held for over a century.

The roughly 21-year-old French commander (later renowned as a great general) led the victory in 1643.
It broke the legend of the Spanish tercios.
The battle signaled Spain's decline as the leading European power.

Round 5

Battle of the Falkland Islands

Battle of the Falkland Islands · 1914 · 20th Century

Why there: The remote Falkland Islands were a British-held coaling station guarding the sea lanes around Cape Horn, so Von Spee's German squadron sought to raid it just as a superior British force happened to be refueling there, trapping the raiders in the cold South Atlantic.

Why then: In 1914 global empires depended on far-flung coaling stations and cruiser squadrons to police worldwide trade routes, and the new battlecruiser—fast enough to hunt and heavily gunned enough to outrange its prey—had just made such a decisive pursuit and destruction possible.

A British force under Admiral Sturdee destroyed Admiral von Spee's German East Asia Squadron in a 1914 naval battle.
It avenged the British defeat at the Battle of Coronel the previous month.
Most of von Spee's squadron was sunk; von Spee and his two sons were among the dead.
