Sabotage at the Aqua Marcia
At midnight, a Roman engineer crawled into a rival city’s aqueduct—and sabotaged its water supply by hand.

Cutting off the lifeblood.
When Rome besieged Praeneste in 82 BC, victory stalled—until an engineer slipped inside the city’s aqueduct. Under cover of night, he blocked the flow, leaving Praeneste’s people thirsty, panicked, and desperate by dawn.
Water wins wars.
Ancient sources say once the city’s water failed, morale collapsed. Some tried digging wells. Others abandoned hope entirely. Rome’s legions watched as the gates opened—not to the sword, but to thirst. In ancient Italy, control the aqueduct and you controlled the city.
Dirty tricks, clean results.
Rome celebrated its engineers as national heroes. Today, their aqueducts stand as monuments—but you don’t see many statues of the men who crawled through the darkness, wrench in hand.
Rome fought dirty as well as brave—sometimes the path to victory was through the sewer, not the battlefield.
