The Persians lost at the Bay of Salamis because they got crowded in the bay and could not maneuver.

Explanation:

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 the year 480 BC, which resulted in the victory of the numerically inferior Greeks.

The Persian fleet sailed into Salami's strait and tried to block both entrances. In the cramped conditions along the strait, the large number of combatants was an active obstacle, as the ships had difficulty maneuvering and were disorganized. The Greeks seized the opportunity and shaped their fleet linearly, claiming a decisive victory.

Answer: They got crowded in the bay and could not maneuver.
