The Storm That Wrecked Persia’s Navy
Lightning split the sky above Artemisium—the Persian fleet shattered before the Greeks ever raised an oar.

Storm before battle
On the eve of Artemisium, Xerxes’ massive fleet anchored off the Greek coast. As the Persians slept, thunder cracked and hurricane winds hurled their ships onto the rocks—destroying over a third of their force before a single Greek trireme launched.
Weather tips the scales
With hundreds of enemy ships smashed, the Greeks faced a shaken foe. Herodotus says some called it the gods’ intervention. Strategy mattered, but sometimes, so did the weather—and lightning did as much as any admiral.
Nature, not strategy, struck the first blow at Artemisium and changed the balance of naval power overnight.
