These are the 5 rounds every player got on September 18, 2026, with the answers and the history behind them. This day is finished, so nothing here spoils a puzzle you can still play — today’s Daily Challenge is a different five events.

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

Peterloo Massacre

Peterloo Massacre · 1819 · 19th Century

Why there: Manchester was a booming cotton-industry city whose population had exploded yet still had no parliamentary representation, making its St Peter's Field the natural gathering ground for demands that the swollen unrepresented masses finally get the vote.

Why then: Post-Napoleonic economic distress, the Corn Laws, and rising working-class radicalism collided with a nervous government that lacked a professional police force, so authorities relied on amateur mounted yeomanry who panicked and charged the crowd.

The massacre took place at St Peter's Field in a major English industrial city (1819).
The grim nickname parodied a famous battle of four years earlier.
It spurred the campaign for parliamentary reform and a freer press.

Round 2

Battle of Saule

Battle of Saule · 1236 · Medieval

Why there: The Sword Brothers were pushing their crusade into Samogitia, whose dense forests, rivers, and marshes let local pagan tribes ambush heavily armored knights in terrain where cavalry and formations bogged down and lost their advantage.

Why then: By 1236 the Northern Crusades had reached the last unconverted corner of the Baltic, and the Livonian Sword Brothers were overstretched and weakened, so their catastrophic loss forced their remnants to merge into the Teutonic Order the next year.

The Battle of Saule (1236) was a catastrophic defeat for the Livonian Brothers of the Sword against Samogitian and allied Baltic forces.
The disaster led the surviving Brothers to merge into the Teutonic Order in 1237.
Lithuania later commemorated the battle as a foundational moment of national resistance.

Round 3

My Lai Massacre

My Lai Massacre · 1968 · 20th Century

Why there: My Lai lay in Quang Ngai province, a rural coastal region of South Vietnam long considered a Viet Cong stronghold, so U.S. forces treated its hamlets as hostile territory during search-and-destroy operations.

Why then: By 1968 the frustration of a guerrilla war with no clear front lines, combined with the shock of the Tet Offensive, had eroded discipline and blurred the line between combatants and civilians for American troops.

The My Lai Massacre occurred in March 1968 during the Vietnam War.
U.S. troops killed an estimated 347-504 unarmed civilians.
Lieutenant William Calley was the only person convicted.

Round 5

Battle of Vienna

Battle of Vienna · 1683 · Early Modern

The relief broke a long Ottoman siege of the Habsburg capital in 1683.
An allied relief force, with a famous king leading a massive cavalry charge of winged hussars, won the day.
It marked the high-water mark of Ottoman expansion into Central Europe.
