Round 1

Battle of Roncevaux Pass

Battle of Roncevaux Pass · 778 · Medieval

Why there: The narrow Roncevaux Pass through the Pyrenees was the only practical route for a large army crossing between Spain and Francia, and its steep terrain let the local Basque highlanders trap the strung-out rearguard where numbers and cavalry counted for nothing.

Why then: Charlemagne's expanding Frankish empire had just pushed into Iberia amid the fractured politics of Muslim and Christian rivals, and his 778 withdrawal left resentful Basques ready to strike—an ambush that only later, in a more literate, chivalric age, was mythologized into the Song of Roland.

• This battle occurred in 778 CE in a pass of the Pyrenees.
• Basque fighters ambushed the rearguard of Charlemagne's retreating army; the commander Roland was killed (the Battle of Roncevaux Pass).
• The event inspired the medieval epic 'The Song of Roland'.

Round 3

Battle of Lützen

Battle of Lützen · 1813 · 19th Century

Why there: Lützen sits on the plains of Saxony astride the roads to Leipzig, a strategic crossroads where Napoleon's westward-based forces had to block the Russo-Prussian advance to keep his grip on the German states of the Confederation of the Rhine.

Why then: Coming right after the destruction of the Grande Armée in the 1812 Russian winter, spring 1813 was the moment Prussia switched sides and the coalition pressed while Napoleon scrambled to field hastily raised conscripts before his rebuilt army could mature.

• This battle opened Napoleon's German campaign of the Sixth Coalition (1813).
• Marshal Bessières was killed by a cannonball at Rippach the day before the battle, leaving the French short of cavalry leadership.
• The French held the field but lacked the cavalry to pursue.

Round 4

1908 Messina earthquake

1908 Messina earthquake · 1908 · 20th Century

Why there: Messina sits astride a narrow strait where the African and Eurasian plates grind together, a seismically active fault zone whose submarine slippage both shook the tightly packed port city and unleashed a tsunami that swept its low-lying waterfront and Reggio Calabria opposite.

Why then: By 1908 the strait's prosperity had crowded people into dense masonry buildings with no earthquake-resistant design, while early-20th-century steamships and telegraphs allowed international navies to mount a rapid relief response that earlier eras could not.

• The 1908 Messina earthquake struck Sicily and Calabria in December 1908.
• It and the resulting tsunami killed an estimated 75,000-82,000 people.
• It remains one of the deadliest earthquakes in European history.

Round 5

Boston Massacre

Boston Massacre · 1770 · Early Modern

Why there: Boston was the commercial hub and hotbed of colonial resistance, where the customs house symbolized British taxation and stationed troops rubbed daily against a resentful port-city population.

Why then: By 1770 Britain's post-war debts had triggered a decade of new taxes and the quartering of soldiers among civilians, so friction that would ignite the Revolution was peaking just as no compromise had yet been reached.

• In this 1770 incident, British soldiers killed five colonists outside a colonial customs house.
• Among the dead was Crispus Attucks, often regarded as the first casualty of the American Revolution.
• Future president John Adams defended the soldiers in court, securing acquittals for most of them.
