Captain Nathan Algren: There was once a battle at a place called Thermopylae, where three hundred brave Greeks held off a Persian army of a million men. A million...do you understand this number?
Katsumoto: I understand this number.
--The Last Samurai
The Battle of Thermopylae (480 BC) pitted a few thousand Greeks against 100,000+ invading Persians. The vastly outnumbered Greek force held off the Persians for seven days in one of the most remarkable last stands in history.
At one point, the Persians demanded that the Greeks throw down their weapons in surrender. The Greek commander responded, "Molon labe" ["Come and take them"]
Today's gun grabbers face similar prospects.
