Though the Spartan government disavowed responsibility for his action, the garrison remained in occupation till B.C. 378.

But though this year witnessed the success of the Spartans at Olynthus and Phlius, it really proved the turning-point in the struggle and the beginning of the fall of the Spartan supremacy.
