After the battle the Athenians set up a trophy and gave up their dead under a truce to the Potidaeans. There were slain, of the Potidaeans and their allies a little less than three hundred, and of the Athenians alone[*](Thucydides omits the loss of the allies of the Athenians.) about a hundred and fifty, and also their general Callias.
The city wall on the isthmus side[*](The wall on the Isthmus side of the Potideans is the τεῖχος of Thuc. 1.62.6; the wall to Pallene is that mentioned in Thuc. 1.56.2 as τὸ ἐς παλλήνων τεῖχος.) the Athenians immediately cut off by a transverse wall and set a guard there, but the wall toward Pallene was not shut off.[*](The investment of Potidaea was effected by walling off first the northern and then also the southern city wall by a blockading wall; on the west and east, where the city extended to the sea, the blockade was made with ships.) For they thought their numbers were insufficient to maintain a garrison on the isthmus and also to cross over to Pallene and build a wall there too, fearing that, if they divided their forces, the Potidaeans and their allies would attack them.
