Round 1

Battle of Adrianople

Battle of Adrianople · 378 · Antiquity

Why there: Adrianople sat on the great overland road guarding the approach to Constantinople, the eastern capital, so a Gothic force loose in Thrace forced the Romans to give battle there to shield the imperial heartland.

Why then: By 378 the Huns' westward push had driven the Goths across the Danube as desperate refugees, and Roman mistreatment turned them into an armed revolt just as the empire's overstretched, divided command left an impatient emperor to fight without waiting for reinforcements.

• At the Battle of Adrianople (378 CE), the Goths annihilated the Eastern Roman army and killed Emperor Valens.
• Valens attacked without waiting for reinforcements from his nephew Gratian.
• The disaster is often cited as a milestone in the decline of the Western Roman Empire.

Round 3

Battle of Breitenfeld

Battle of Breitenfeld · 1631 · Early Modern

Why there: The battle unfolded on the open plains near Leipzig, a wealthy Saxon trading hub in central Germany that sat astride the routes the Swedish and imperial armies both needed to control as they contested the Protestant heartland.

Why then: By 1631 the Thirty Years' War had turned decisively when Sweden's Gustavus Adolphus intervened with a reformed army whose lighter, mobile linear tactics and integrated field artillery outclassed the old massed tercio formations still used by the Catholic imperial forces.

• The Protestant king won his first major victory of the Thirty Years' War here in 1631.
• His combined-arms tactics shattered the army of the Catholic League's veteran commander.
• The win opened much of Catholic Germany to Protestant campaigning.

Round 4

Battle of Covadonga

Battle of Covadonga · 718 · Medieval

Why there: The steep, easily-defended valleys of the Asturian Picos de Europa in the far north offered refuge to Christian fighters where Muslim cavalry lost its advantage, at the edge of a peninsula that Umayyad armies had swept across but never fully subdued in its rugged mountains.

Why then: The clash came in the aftermath of the rapid 711 Umayyad conquest of Visigothic Iberia, when Muslim forces were overstretched at their northern limit and a local resistance could coalesce before central control solidified.

• This battle is traditionally dated to between 718 and 722 CE.
• Pelagius (Don Pelayo) led the Asturian resistance against Umayyad forces (the Battle of Covadonga).
• It is regarded as the symbolic beginning of the Reconquista and the founding of the Kingdom of Asturias.

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.
