A deep sea diver responsible for bringing down the Persian Navy
Hydna (sometimes Cyana) of Scione fought in the same war as Artemisia of Caria – only on the opposing side. Growing up in a seaside town, she was a strong swimmer and proficient deep sea diver.
When the Persian navy began closing in on the Greek coast in 490 BCE, Hydna and her father volunteered to help defend their Empire. Seeing that a storm was brewing, the father and daughter came up with an elegant plan of attack.
At nightfall, the pair swam for ten miles through storm-tossed waters to reach the Persian ships. Silent and unseen, they then took their knives to the moorings, cutting the ropes and dragging away the anchors.
Untethered, the Persian ships were defenseless against the storm and crashed against each other, causing a huge amount of damage. Hydna and her fathers’ actions prevented battle until the Persians could recoup their losses, buying time for the Greek forces.
