Henry Morgan led a massive privateer army on a grueling 50-mile trek through the Panama Isthmus in 1671 to capture and sack the incredibly wealthy Panama City.The journey became a "starving raid" as Spanish scorched-earth tactics deprived the men of provisions, forcing them to survive by eating leaves, leather bags, and even dogs.Despite their extreme hunger, the force successfully routed the Spanish militia at the Battle of Mata Asnillos and plundered the city for millions in treasure.
