The foundation of Halos

The lasting result of the non-battle was the refoundation of Halos, which had been destroyed in 346 by Parmenion, one of the generals of the Macedonian king Philip II. In 302, the population was permitted to return, and they rebuild their town in the old camp of Demetrius ('old' Halos was a bit more to the east).

And first he gathered together his fleet and his land army in Chalcis of Euboea; then, learning that Cassander had already occupied the passes in advance [1], he gave up the attempt to advance into Thessaly by land, but sailed along the coast with the army into the port of Larisa.[2] Disembarking the army, he captured the city at once; and taking the acropolis, he imprisoned the garrison and put them under guard, but he restored their autonomy to the people of Larisa. Thereafter he won over Antrones and Pteleum, and when Cassander would have transported the people of Dium and Orchomenus  into Thebes, he prevented the transplanting of the cities.[3]

But when Cassander saw that Demetrius' undertakings were prospering, he first protected Pherae and Thebes with stronger garrisons; and then, after collecting his whole army into one place, he encamped over against Demetrius. He had in all 29,000 foot-soldiers and 2,000 horsemen. Demetrius was followed by 1500 horsemen, not less than 8,000 Macedonian foot-soldiers, mercenaries to the number of 15,000, 25,000 from the cities throughout Greece, and at least 8,000 of the light armed troops and of the freebooters of all sorts who had gathered for the fighting and the plundering; so that there were in all about 56,000 foot soldiers.[4]

For many days the camps were pitched opposite each other, and the battle lines were drawn up on both sides, but neither came forward into battle since each was awaiting the decision of the whole matter that would take place in Asia [5]. Demetrius, however, when the people of Pherae called upon him, entering their city with part of his army and taking the citadel, dismissed the soldiers of Cassander on terms and restored their liberty to the people of Pherae.

Note 2:
Towns in the country between Thermopylae and Thessaly.

Note 3:
Obviously, Cassander was thinking of fortifying Thebes (a town in Phthiotis, not Boeotian Thebes) by adding the population of other towns.

Note 4:
A camp built to give shelter to so many people must have resembled a real city, which was indeed to grow on this spot.

Note 5:
Where Lysimachus and Antigonus Monophthalmus were fighting.
