This decisive engagement in the Revolt of the Ionian Cities against Persia has its name from Lade Island, a dissected ridge of rock in the entrance to the roadstead of Miletus, where the naval contingents of the allied Ionian cities were concentrated to oppose a fresh Persian armada of Phoenician, Cypriote, Cilician, and Egyptian ships, 600 in all (vi. 9), of which 353 were war-vessels, probably the provincial levies; but their commanders collaborated (vi. 6). They had two immediate objects: to destroy the Greek squadrons, and to effect a landing in the home territory of Miletus, where a provincial land-force was to meet them for the siege of the city, advancing by the Maeander valley road from beyond Mount Grion and probably based also on the fertile valley of Mylasa about twenty miles south-east.
