Xenophon records the joyful moment when the Ten Thousand (by then actually far fewer), from the heights of Mount Theches, saw the sea and friendly Greek colonies on the coast, which signified their escape had been made good, whereupon they shouted Thalatta! Thalatta! (The sea! The sea!). Soon after, Xenophon's men reached Trapezus on the coast of the Black Sea (Anabasis 4.8.22). Before they departed, the Greeks made an alliance with the locals and fought one last battle against the Colchians, vassals of the Persians, in mountainous country. Xenophon ordered his men to deploy their line extremely thin, so as to overlap the enemy, while keeping a strong reserve. The Colchians, seeing they were being outflanked, divided their army to check the Greek deployment, opening a gap in their line through which Xenophon rushed in his reserves, scoring a Greek victory.
