Leonidas was the leader of the 300 Spartans at the battle of Thermopylae in the year 480 BC. Takezaki Suenaga was the most celebrated of the samurai who turned back the Mongol invasion at Hakata Bay, in the year 1274 AD. Some background - Spoiler: Spartans King Xerxes of Persia had decided to invade Greece, and brought along an army that most historians agree contained at least one million men. The Greek city-states banded together, and a small army of Greeks, led by 300 Spartans, went to hold off this colossal army at a pass called Thermopylae. The Spartans were supremely disciplined warriors, trained from birth to be the best soldiers in the world at that time. The Spartan soldiers had mastered the phalanx formation - essentially a tight wall of overlapping shields. The Spartans held back the advance of the colossal Persian army for a week. Only when the Greeks were betrayed, and the Persians showed another pass, did they break the Spartan ranks - and even then, the Spartans fought to the death. King Leonidas and his 300 men were all killed, but not before inflicting huge casulties on the Persian Army. The Spartans fought with a combination of short swords, short spears, and shields. They wore leather armor. Spoiler: Samurai Takezaki Suenaga is widely regarded as the greatest Samurai of Japan's Kamakura period - 1185-1333. When the Mongols sent a fleet of 800 ships - containing some 15,000 Chinese warriors - to invade Japan, The Japanese responded with a force of about 2,000 Samurai. The Samurai were used to a very ritualistic way of battle - warriors would step out of rank and challenge someone of approxmately equal rank to one-on-one contests. To their dismay, The Samurai found that the Chinese were more fond of shooting clouds of poison-tipped arrows the fighting one-on-one. The Samurai were doing poorly. However, Suenaga and his 5 retainers rallied a force of 100 samurai, and despite the Chinese use of gunpower as explosives (something the Japanese had never seen) and their superior bowmen, Suenaga's group of 100 held off the Mongols until nightfall, when the Korean boat pilots decided to reembark their troops and sail, fearing a tempest would wreck them on the rocks of the bay - but instead, a typhoon came and sank their fleet at sea. The Typhoon that would later be called Kamikaze- the divine wind. The Samurai fought with the familiar katana, short swords, and a long, unwieldy polearm called a Naginata. They wore wooden/woven armor. Anyway, to the question: Which elite group of uber-warriors would prevail in a battle?
