When Agis III succeeded his father as King of Sparta in 338 BC, Alexander the Great was off in Persia fighting Emperor Darius III. Figuring it was a good time to fuck some shit up, A3 as he was known in the underground hip-hop scene, rallied anti-Macedonian leaders to his cause, raised a decent army, invaded Crete and started pushing his way towards Athens.
Agis wasn't above petty vandalism to make his point.
Deciding this guy wasn't fucking around, Alexander sent his most battle hardened general and an army of 40,000 men to open a 10-gallon drum of thermonuclear whoop-ass on the Spartans. On the battlefield outside the city of Megalopolis (they just don't name cities like they used to) the two armies faced off in one of the largest battles ever fought between Greek armies in the Classical Age.
Despite being outnumbered roughly two-to-one, Agis wasn't going to back down from any opportunity to drench the tip of his spear in a few gallons of human plasma. Screaming the most horrible profanities they could think of as they went, A3 charged out in front of his men and fought like a goddamned madman, slashing people with his Spartan blades, before receiving a disturbing number of reciprocal wounds across his chest, head and legs.
