Round 1

Battle of Malplaquet

1709 · Early Modern

Why there: Malplaquet sat astride the wooded frontier between the Spanish Netherlands and France, a natural gap defended by Villars to block the Allied march toward Paris after their string of Flanders victories.

Why then: The War of the Spanish Succession pitted a Grand Alliance against Louis XIV's France, and by 1709 famine and exhaustion had pushed a cornered France to fight desperately with the new mass armies, muskets, and field fortifications that made linear battles enormously lethal.

• The Battle of Malplaquet (1709) was the costliest battle of the War of the Spanish Succession.
• Marlborough and Eugene defeated the French under Marshal Villars near the Franco-Belgian border.
• The allies suffered roughly twice the casualties of the French, blunting the appetite for further offensives.

Round 2

Battle of Warsaw

1920 · 20th Century

Why there: Warsaw was the capital of the newly independent Poland, sitting on the Vistula River as the last defensible barrier before the Red Army could pour westward into Central Europe.

Why then: The 1917 Russian Revolution and the collapse of empires after World War I created both a Soviet state eager to spread revolution and a resurrected Poland determined to secure its 1918 independence, making their clash inevitable at that moment.

• The battle was fought during the Polish-Soviet War of 1919-1921.
• Polish forces under Jozef Pilsudski decisively defeated the advancing Red Army.
• It is sometimes called the 'Miracle on the Vistula' and halted Soviet expansion into Europe.

Round 3

Battle of Legnica

1241 · Medieval

Why there: Legnica in Silesia sat astride the northern route into Poland and the German lands, so the Mongols' flanking detachment struck there to shield their main invasion of Hungary from any relief army gathering in fragmented, principality-divided Central Europe.

Why then: By 1241 the Mongol Empire under Ögedei had consolidated the steppe and perfected fast, coordinated cavalry campaigns, reaching a divided Christendom whose slow, heavy feudal knighthood had no answer to horse-archer mobility and feigned-retreat tactics.

• The Battle of Legnica (1241) saw Mongol forces destroy a combined Polish, Moravian, and Teutonic Knight army under Duke Henry II the Pious, who was killed.
• It was fought days before the Battle of Mohi as part of the coordinated Mongol invasion of Europe.
• Chroniclers reported that the Mongols made a grim count of the fallen after the battle, a detail that fed the legend of the invasion's ferocity.

Round 4

Battle of Avarayr

451 CE · Antiquity

Why there: Armenia sat on the contested frontier between the Sasanian and Roman empires, and the rugged Vaspurakan highland plain of Avarayr gave the outnumbered Armenian nobility a defensible battlefield to resist Persian control of their kingdom.

Why then: By 451 Armenia had adopted Christianity as its identity generations earlier, so when the Sasanian shah Yazdegerd II tried to impose Zoroastrianism to bind the buffer province tighter to Persia, the clash of a now-Christian people against imperial fire-worship became inevitable.

• The Battle of Avarayr (451 CE) was fought between Christian Armenians under Vardan Mamikonian and the Sasanian Empire.
• The Sasanians sought to impose Zoroastrianism on Armenia.
• Though the Armenians lost the battle and Vardan died, later concessions preserved Armenian Christianity, and Vardan became a venerated saint.
