The Eclipse
According to Herodotus (1.74):
"In the sixth year a battle took place in which it happened, when the fight had begun, that suddenly the day became night. And this change of the day Thales the Milesian had foretold to the Ionians laying down as a limit this very year in which the change took place. The Lydians however and the Medes, when they saw that it had become night instead of day, ceased from their fighting and were much more eager both of them that peace should be made between them."

Since the exact dates of eclipses can be calculated, the Battle of the Eclipse is the earliest historical event of which the date is known with such precision.

According to NASA, the eclipse peaked over the Atlantic Ocean at 37.9° N 46.2° W and the umbral path reached south- western Anatolia in the evening hours, and the Halys River is just within the error margin for delta-T provided.


Why we call it HALYS

Pronounced: “howl’ us”

The HALYS brand multi-layer system was originally created (as the Protective Combat Uniform) for the United States Special Operations Forces.

After a grueling winter in Afghanistan, SOF leaders sent an urgent request for a lighter, more efficient clothing system designed for the most extreme weather conditions.

Using cutting-edge technology, and by working closely with this elite military unit throughout the development, design and testing phases, the PCU prototype was created.

With a sincere vested interest in the functionality of the PCU, SOF leaders were asked to assist in the brand development process.

From those initial marketing and brand development meetings, the HALYS name was born.

The product brand was named for the Battle of Halys, significant in military history because the date of the battle can be pinpointed with precicision.

On May 28, 585 BC, as King Alyattes of Lydia battled Cyaxares of Media along the Halys River in Asia Minor, a solar eclipse darkened the skies and brought the battle to a standstill. According to Herodotus (1.74) “the Lydians and the Medes, when they saw that it had become night instead of day, ceased from their fighting and were eager both of them that peace should be made between them." This battle is significant for not only bringing an end to the fifteen-year war between the Lydians and the Medes, but also as a specific point in history which can be verified with precision.
