The Battle of Seawall was an infamous clash in the earliest years of the Republic, and probaly the largest sea battle ever fought under the three suns. The Battle of Seawall involved four massive fleets; the Itreyan Navy under command of the Great Unifier, Francisco I, and a tithed fleet from the vassal state of Vaan clashed with Dweymeri clan ships under command of Bara Sundancer of the Threedrake clan, and an armada of pirate lords who had sworn to resist the Itreyan dominance of the seas. The resistance didn't last long.
