In 1925, another dispute revolving around the redrawing of Europe's international borders after WW1 broke out.
October 1925: Small fight broke out, in which 2 Greek border guards were killed.
Greece suspected Bulgarian attack, and ordered an immediate invasion.
The League condemned Greece and demanded both sides end their operations. This resulted in a withdrawal of troops within 60 hours of this being ordered.
Both sides agreed to end conflict and it was over by 29 October 1925. The council awarded Bulgaria 30 million Bulgarian 'lev' in compensation.
