The Boeotians immediately sent for javelin-men and slingers from the Malian Gulf. They1
had been joined after the battle by the Corinthians with two thousand hoplites, and by the Peloponnesian garrison which had evacuated Nisaea2
, as well as by some Megarians. They now marched against Delium and attacked the rampart, employing among other military devices an engine, with which they succeeded in taking the place; it was of the following description.
They sawed in two and hollowed out a great beam, which they joined together again very exactly, like a flute, and suspended a vessel by chains at the end of the beam; the iron mouth of a bellows directed downwards into the vessel was attached to the beam, of which a great part was itself overlaid with iron.
This machine they brought up from a distance on carts to various points of the rampart where vine stems and wood had been most extensively used, and when it was quite near the wall they applied a large bellows to their own end of the beam, and blew through it.
The blast, prevented from escaping, passed into the vessel which contained burning coals and sulphur and pitch; these made a huge flame, and set fire to the rampart, so that no one could remain upon it.
The garrison took flight, and the fort was taken. Some were slain; two hundred were captured; but the greater number got on board their ships and so reached home.
