In 1552, the Portuguese carrack São João shattered on a remote stretch of the South African coast, throwing more than 600 people into the surf. Those who survived the wreck were left stranded with almost no food or water , and faced a single impossible option.
March north.
Across a brutal coastline.
Barefoot, starving, hunted, and collapsing one by one.
What followed became one of the deadliest survival marches in history.
