Being at a loss which of the two risks to choose, whether to go to Olynthus or to Potidaea, he at last determined to draw his men into as small a space as possible, and force his way with a run into Potidaea.

Not without difficulty, through a storm of missiles, he passed along by the breakwater through the sea, and brought off most of his men safe, though a few were lost.

Meanwhile the auxiliaries of the Potidaeans from Olynthus, which is about seven miles off and in sight of Potidaea, when the battle began and the signals were raised, advanced a little way to render assistance; and 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.
