It was decided that they should guard the pass of +Thermopylae [22.5583,38.8] (Perseus) Thermopylae, for they saw that it was narrower than the pass into +Thessaly [22.25,39.5] (region), Greece, Europe Thessaly and nearer home.

The pass, then, which brought about the fall of those Greeks who fell at +Thermopylae [22.5583,38.8] (Perseus) Thermopylae, was unknown to them until they came to +Thermopylae [22.5583,38.8] (Perseus) Thermopylae and learned of it from the men of +Trachis [22.55,38.8] (Perseus) Trachis. This pass they were resolved to guard and so stay the barbarian's passage into Greece [22,39] (nation), EuropeHellas, while their fleet should sail to +Artemisium [23.2417,39.0083] (Perseus) Artemisium in the territory of Histiaea.
