Paul Collins Film presents Chasca's "So Long, Crassus," a tale of a soldier's defiant feelings toward his leader. If you're not completely up on your Romain history, Wikipedia offers:
"The Battle of Carrhae was fought in 53 BC between the Parthian Empire and the Roman Republic near the town of Carrhae. The Parthian Spahbod ("General") Surena decisively defeated a numerically superior Roman invasion force under the command of Marcus Licinius Crassus. It is commonly seen as one of the earliest and most important battles between the Roman and Parthian empires and one of the most crushing defeats in Roman history.
...Crassus marched his army directly through the deserts of Mesopotamia. His army clashed with Surena's force near Carrhae, a small town in modern-day Turkey. Despite being heavily outnumbered, Surena's cavalry completely outmaneuvered the Roman heavy infantry, killing or capturing most of the Roman soldiers. Crassus himself was killed when truce negotiations turned violent. His death led to the end of the First Triumvirate and the resulting civil wars between Julius Caesar and Pompey."
