the Macedonian horse formed against them to
prevent it. But on victory speedily declaring for the Athenians and the
signals being taken down, they retired back within the wall; and the
Macedonians returned to the Athenians. Thus there were no cavalry
present on either side. After the battle the Athenians set up a trophy,
and gave back their dead to the Potidaeans under truce. The Potidaeans
and their allies had close upon three hundred killed; the Athenians a
hundred and fifty of their own citizens, and Callias their general.

The wall on the side of the isthmus had now works at once raised against
it, and manned by the Athenians. That on the side of Pallene had no
works raised against it. They did not think themselves strong enough at
once to keep a garrison in the isthmus and to cross over to Pallene and
raise works there; they were afraid that the Potidaeans and their allies
might take advantage of their division to attack them. Meanwhile the
Athenians at home learning that there were no works at Pallene, some
time afterwards sent off sixteen hundred heavy infantry of their own
citizens under the command of Phormio, son of Asopius. Arrived at
Pallene, he fixed his headquarters at Aphytis, and led his army against
Potidaea by short marches, ravaging the country as he advanced. No one
venturing to meet him in the field, he raised works against the wall
on the side of Pallene. So at length Potidaea was strongly invested on
either side, and from the sea by the ships co-operating in the blockade.
Aristeus, seeing its investment complete, and having no hope of its
salvation, except in the event of some movement from the Peloponnese, or
of some other improbable contingency, advised all except five hundred
to watch for a wind and sail out of the place, in order that their
provisions might last the longer. He was willing to be himself one of
those who remained. Unable to persuade them, and desirous of acting on
the next alternative, and of having things outside in the best posture
possible, he eluded the guardships of the Athenians and sailed out.
Remaining among the Chalcidians, he continued to carry on the war; in
particular he laid an ambuscade near the city of the Sermylians, and cut
off many of them; he also communicated with Peloponnese, and tried to
contrive some method by which help might be brought. Meanwhile, after
the completion of the investment of Potidaea, Phormio next employed
his sixteen hundred men in ravaging
