The Battle of Salamis was a naval battle fought between an alliance of Greek city-states under Themistocles, and the Persian Empire under King Xerxes in 480 BC. It resulted in a decisive victory for the outnumbered Greeks. The battle was fought in the straits between the mainland and Salamis, an island in the Saronic Gulf near Athens. In the cramped conditions of the Straits, the great Persian numbers were an active hindrance, as ships struggled to maneuver and became disorganized. Seizing the opportunity, the Greek fleet formed in line and scored a decisive victory. Oil on canvas by Wilhelm von Kaulbach (cropped and cleaned).
