We’ll there was that time Kublai Khan tried to invade Japan with the largest amphibious assault in history (until D-day) and got absolutely wrecked by a typhoon.
Then tried again a few years later, with an even larger force, and got wrecked by another typhoon.

You can’t leave aside the fact that those typhoons were called “Divine Winds”, or kamikaze.
This kamikaze was far more effective than the later one, though.
I doubt if it counts as a blunder, but thanks for sharing anyway.
