History of the Peloponnesian War

On the present occasion the cart was already at the gates, which had been opened in the usual way for the boat, when the Athenians, with whom this had been concerted, saw it, and ran at the top of their speed from the ambush in order to reach the gates before they were shut again, and while the cart was still there to prevent their being closed; their Megarian accomplices at the same moment killing the guard at the gates.

The first to run in was Demosthenes with his Plataeans and Peripoli, just where the trophy now stands; and he was no sooner within the gates than the Plataeans engaged and defeated the nearest party of Peloponnesians who had taken the alarm and come to the rescue, and secured the gates for the approaching Athenian heavy infantry.

After this, each of the Athenians as fast as they entered went against the wall.
