Meanwhile the main body of the troops in the island (that under Epitadas), seeing their outpost cut off and an army advancing against them, serried their ranks and pressed forward to close with the Athenian heavy infantry in front of them, the light troops being upon their flanks and rear. However, they were not able to engage or to profit by their superior skill, the light troops keeping them in check on either side with their missiles, and the heavy infantry remaining stationary instead of advancing to meet them; and although they routed the light troops wherever they ran up and approached too closely, yet they retreated fighting, being lightly equipped, and easily getting the start in their flight, from the difficult and rugged nature of the ground, in an island hitherto desert, over which the Lacedaemonians could not pursue them with their heavy armour.
