Why Did the Final Battle at Thermopylae Change Defensive Warfare Forever?
This legendary question leads us to one of the most famous last stands in ancient and medieval history — the Battle of Thermopylae, where King Leonidas and his 300 Spartans, alongside a few thousand Greek allies, faced the enormous Persian army of King Xerxes, numbering over 100,000.
