Round 1
Battle of the River Plate
1939 · 20th Century
Why there: The wide River Plate estuary sat astride the busy shipping lanes carrying South American grain and meat to Britain, making it a rich hunting ground for a commerce raider and a natural place for hunting cruisers to intercept her, while nearby neutral Montevideo offered the only refuge for a damaged ship far from home.
Why then: In the opening months of World War II, Germany deployed fast, long-range pocket battleships to strangle British trade before convoy defenses matured, and the Royal Navy answered with cruiser hunting groups. It was a clash only possible once naval gunnery and radio-coordinated pursuit had reached this 1939 scale.
This was the Battle of the River Plate in December 1939, the first major naval battle of the Second World War.
The German ship was the Admiral Graf Spee, scuttled off Montevideo, Uruguay.
Her captain, Hans Langsdorff, took his own life days after the scuttling.
Round 2
Battle of Fontenoy
1745 · Early Modern
Why there: Fontenoy lay on the invasion route into the Austrian Netherlands, a strategically vital, densely fortified crossroads whose control opened the road to the wealthy Low Countries that great powers had long contested.
Why then: The War of the Austrian Succession pitted France against Britain, Austria, and their allies over the Habsburg inheritance, and the linear tactics of drilled musket-and-cannon armies made such head-on infantry clashes the defining battles of the era.
The Battle of Fontenoy (1745) was a French victory in the War of the Austrian Succession.
Marshal Saxe, gravely ill, directed the French army while King Louis XV watched from the field near Tournai in present-day Belgium.
It is famed for the apocryphal invitation, 'Gentlemen of the French Guard, fire first.'
Round 3
Assassination of Abraham Lincoln
1865 · 19th Century
Why there: Washington was the Union capital and the president attended Ford's Theatre unguarded there, giving a Confederate-sympathizing actor easy access in a city still filled with defeated Southern loyalists.
Why then: The Confederacy's surrender days earlier enraged pro-slavery partisans who saw Lincoln as the architect of their defeat, making the fragile, celebratory close of the Civil War the flashpoint for a revenge killing.
This was the assassination of Abraham Lincoln at Ford's Theatre in Washington, D.C., on April 14, 1865.
The assassin was actor John Wilkes Booth, who shouted 'Sic semper tyrannis.'
Lincoln died the following morning at the Petersen House across the street.
Round 4
Battle of Mu'tah
629 CE · Medieval
Why there: Mu'tah lay near the borderlands of the Byzantine Empire and its Arab Ghassanid clients in the Levant, making it the natural frontier zone where the expanding power from the Arabian interior first collided with the Christian empire to the north.
Why then: By 629 the newly unified Muslim polity in Arabia was strong enough to project force beyond the peninsula, while Byzantium, exhausted by its long war with Persia, faced a rising rival probing its southern frontier for the first time.
The Battle of Mu'tah (629 CE) pitted an early Muslim force against the Byzantine Empire and its Arab allies.
Three appointed commanders were killed before Khalid ibn al-Walid took command and managed a withdrawal.
It was fought near Mu'tah in present-day Jordan.
Round 5
Battle of the Teutoburg Forest
9 CE · Antiquity
Why there: The dense marshy woodlands east of the Rhine forced the Roman column into a narrow, strung-out line where their disciplined battle formations were useless, giving the ambushing Germanic tribes on their own home terrain a decisive advantage.
Why then: Rome under Augustus was at the height of its expansionist confidence, pushing to make the Elbe rather than the Rhine its frontier, but its reliance on newly subdued Germanic auxiliaries, like the Roman-trained Arminius, created the insider betrayal that only this brief window of overreach allowed.
The Battle of the Teutoburg Forest in 9 CE destroyed three Roman legions led by Publius Quinctilius Varus.
The Cheruscan leader Arminius, who held Roman citizenship and equestrian rank and had commanded Germanic auxiliaries, orchestrated the ambush against his former patrons.
Emperor Augustus reportedly lamented, 'Quintili Vare, legiones redde!' ('Varus, give me back my legions!'); the defeat fixed the Rhine as Rome's frontier.
