town that had been allied with Athens in the time of her prosperity now became her enemy.
In their despair the Athenians had taken a desperate step—they had asked their old enemies the Persians to come to their aid.
It was then that Alcibiades saw an opportunity, as he thought, to help the people whom he had so cruelly betrayed, and at the same time to please the Persians.
So he sent a message to the Athenians to say that if they would place the government of Athens in the hands of a party named 'The Four Hundred,' he would be able to persuade Tissaphernes to make an alliance with them. For his master, the great king, would make no terms with Athens as long as she was a democracy.
The Athenians followed Alcibiades' advice, and the government of the city was entrusted to The Four Hundred for a short time. But Alcibiades had not so much influence as he had believed, and the Persian government still refused to help the Athenians.
Partly perhaps in anger with Tissaphernes, partly because the Athenians were not satisfied with the rule of The Four Hundred, Alcibiades helped to overthrow them and to make Athens once again a democracy.
So grateful were the people for his help, that they declared his exile was at an end, and bade him return to Athens.
But although Alcibiades longed to go back to Athens, he was content to wait until he could return covered with glory. By his own request he was given the command of a few ships, and with these he set sail for the Hellespont. Mindarus, the Spartan admiral, with a large army was there, hoping to stop the corn supply of Athens on its way to the city from the Black Sea. If the corn supply was stopped, Athens would starve, and Mindarus knew that the city would then soon be in the hands of the Spartans.
The Athenian fleet was in three divisions, and the one commanded by Alcibiades passed the Hellespont unseen by the enemy and took Mindarus by surprise.
