The Boeotians replied that if they were in Boeotia, they must evacuate that country before taking up their dead; if they were in their own territory, they could do as they pleased: for they knew that, although the Oropid where the bodies as it chanced were lying (the battle having been fought on the borders) was subject to Athens, yet the Athenians could not get them without their leave.
Besides, why should they grant a truce for Athenian ground? And what could be fairer than to tell them to evacuate Boeotia if they wished to get what they asked? The Athenian herald accordingly returned with this answer, without having accomplished his object.
Meanwhile the Boeotians at once sent for darters and slingers from the Malian Gulf, and with two thousand Corinthian heavy infantry who had joined them after the battle, the Peloponnesian garrison which had evacuated Nisaea, and some Megarians with them, marched against Delium, and attacked the fort, and after divers efforts finally succeeded in taking it by an engine of the following description. They sawed in two and scooped out a great beam from end to end, and fitting it nicely together again like a pipe, hung by chains a cauldron at one extremity, with which communicated an iron tube projecting from the beam, which was itself in great part plated with iron. This they brought up from a distance upon carts to the part of the wall principally composed of vines and timber, and when it was near, inserted huge bellows into their end of the beam and blew with them.
The blast passing closely confined into the cauldron, which was filled with lighted coals, sulphur and pitch, made a great blaze, and set fire to the wall, which soon became untenable for its defenders, who left it and fled; and in this way the fort was taken. Of the garrison some were killed and two hundred made prisoners; most of the rest got on board their ships and returned home.
Soon after the fall of Delium, which took place seventeen days after the battle, the Athenian herald, without knowing what had happened, came again for the dead, which were now restored by the Boeotians, who no longer answered as at first. Not quite five hundred Boeotians fell in the battle, and nearly one thousand Athenians, including Hippocrates the general, besides a great number of light troops and camp followers.
Soon after this battle Demosthenes, after the failure of his voyage to Siphae and of the plot on the town, availed himself of the Acarnanian and Agraean troops and of the four hundred Athenian heavy infantry which he had on board, to make a descent on the Sicyonian coast. Before however all his ships had come to shore, the Sicyonians came up and routed and chased to their ships those that had landed, killing some and taking others prisoners; after which they set up a trophy, and gave back the dead under truce.
About the same time with the affair of Delium took place the death of Sitalces, king of the Odrysians, who was defeated in battle, in a campaign against the Triballi; Seuthes, son of Sparadocus, his nephew, succeeding to the kingdom of the Odrysians, and of the rest of Thrace ruled by Sitalces.
The same winter Brasidas, with his allies in the Thracian places, marched against Amphipolis, the Athenian colony on the river Strymon. A settlement upon the spot on which the city now stands was before attempted by Aristagoras, the Milesian (when he fled from King Darius), who was however dislodged by the Edonians; and thirty-two years later by the Athenians, who sent thither ten thousand settlers of their own citizens, and whoever else chose to go. These were cut off at Drabescus by the Thracians. Twenty-nine years after, the Athenians returned (Hagnon, son of Nicias, being sent out as leader of the colony) and drove out the Edonians, and founded a town on the spot, formerly called Ennea Hodoi or Nine Ways. The base from which they started was Eion, their commercial seaport at the mouth of the river, not more than three miles from the present town, which Hagnon named Amphipolis, because the Strymon flows round it on two sides, and he built it so as to be conspicuous from the sea and land alike, running a long wall across from river to river, to complete the circumference.
Brasidas now marched against this town, starting from Arne in Chalcidice. Arriving about dusk at Aulon and Bromiscus, where the lake of Bolbe runs into the sea, he supped there, and went on during the night. The weather was stormy and it was snowing a little, which encouraged him to hurry on, in order, if possible, to take every one at Amphipolis by surprise, except the party who were to betray it. The plot was carried on by some natives of Argilus, an Andrian colony, residing in Amphipolis, where they had also other accomplices gained over by Perdiccas or the Chalcidians. But the most active in the matter were the inhabitants of Argilus itself, which is close by, who had always been suspected by the Athenians, and had had designs on the place. These men now saw their opportunity arrive with Brasidas, and having for some time been in correspondence with their countrymen in Amphipolis for the betrayal of the town, at once received him into Argilus, and revolted from the Athenians, and that same night took him on to the bridge over the river; where he found only a small guard to oppose him, the town being at some distance from the passage, and the walls not reaching down to it as at present. This guard he easily drove in, partly through there being treason in their ranks, partly from the stormy state of the weather and the suddenness of his attack, and so got across the bridge, and immediately became master of all the property outside; the Amphipolitans having houses all over the quarter.
