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

Battle of Lesnaya

Battle of Lesnaya · 1708 · Early Modern

Why there: Lesnaya lay along the forest-and-marsh corridor of eastern Belarus that Lewenhaupt's supply column had to cross to link up with Charles XII's main army pushing deep into Russian territory, giving Peter's mobile force ideal ground to ambush the vulnerable baggage train.

Why then: By 1708 the Great Northern War had turned into a struggle of logistics over distance, and Peter I's scorched-earth strategy and newly reformed, cannon-equipped army could now intercept and cripple Sweden's overextended supply lines rather than face them in open battle.

The Battle of Lesnaya (1708) was fought in present-day Belarus during the Great Northern War.
Peter the Great destroyed General Lewenhaupt's supply column bound for Charles XII's army.
Peter called it 'the mother of the Poltava victory' that came the next year.

Round 2

Battle of Mons Graupius

Battle of Mons Graupius · 83 · Antiquity

Why there: The battle took place in the Scottish highlands because this was the far northern frontier of Roman Britain, where the terrain and scattered Caledonian tribes had allowed the natives to avoid a pitched fight while the legions pushed to the empire's extreme limit.

Why then: By AD 83 Rome had spent decades consolidating Britain and the governor Agricola had campaigned northward for years, so this was the moment his advancing legions finally forced the elusive Caledonians into the decisive open battle they had long avoided.

The Battle of Mons Graupius (83 CE) was fought in the Scottish Highlands between Agricola's Roman forces and the Caledonian Confederacy.
Our sole source is Tacitus, Agricola's son-in-law, who attributes a famous anti-imperial speech to the Caledonian leader Calgacus.
Despite the Roman victory, the region was never permanently subjugated, and the army soon withdrew south.

Round 3

Battle of Legnano

Battle of Legnano · 1176 · Medieval

Why there: Legnano sat on the road between Como and Milan in wealthy, densely urbanized Lombardy, where prosperous trading communes had grown rich and self-governing enough to resist the German emperor's claims over northern Italy's Alpine gateway.

Why then: By the 1170s the revived commercial economy had made the Lombard cities powerful enough to form a defensive league, while Emperor Frederick Barbarossa's repeated campaigns to reassert imperial rights over Italy forced the confrontation precisely when disciplined communal militias could challenge feudal cavalry.

This battle saw a league of northern city communes defeat a Holy Roman Emperor.
The communal militia rallied around the Carroccio, a ceremonial war-wagon.
It was fought near a town in Lombardy, northern Italy, and led toward a peace treaty confirming the towns' rights.

Round 4

Sand Creek massacre

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 5

Armistice of 22 June 1940

Armistice of 22 June 1940 · 1940 · 20th Century

Why there: The Compiègne forest clearing north of Paris was chosen deliberately because it held the railway carriage where Germany had surrendered in 1918, letting Hitler stage a symmetrical humiliation on the exact spot of his nation's earlier defeat.

Why then: By June 1940 Germany's fast-moving armored Blitzkrieg had overrun France in six weeks, collapsing the static defensive strategy of the previous war and forcing Paris to seek terms before its army was destroyed.

This was the Armistice of 22 June 1940 between France and Nazi Germany, signed in the Compiegne forest.
Hitler insisted the same railway carriage used for the 1918 German surrender be brought out for the ceremony.
France was split into an occupied zone and a nominally independent zone governed from Vichy.
