Siege of Theodosia (c. 360 BC)

The Siege of Theodosia in c. 360 BC was the third and final siege by the Bosporan Kingdom under Leukon I against the city of Theodosia, a probable colony of Heraclea Pontica, who had aided the city in two previous sieges.

Prelude
After having been tricked by Tynnichus, Leukon retreated back to Panticapaeum. After his defeat, Leukon had to solidify his position on the throne after getting word that some of his friends and subjects were conspiring against him due his failure at Theodosia. He enlisted the aid of merchants and put down the conspiracy.

Siege
Leukon, seeing that the Heracleotes had left to their city, possibly due to problems with Clearchus of Heraclea who had at the same made himself tyrant of Heraclea, laid a sneak attack on the city of Theodosia before the Heracleotes could prepare an expedition to aid Theodosia. Leukon succeeded in finally defeating Theodosia, who robbed his father of his life.
