Battle of Angista

The Battle of Angista was fought between Bulgarian and Greek troops near the Angista River and village. The two sides were still formally allies in the war. In October 1912, during the First Balkan War, Bulgarian and Greek military forces achieved a joint success by routing the Ottoman troops in Eastern Macedonia. The Greek army entered Thessaloniki, while the Bulgarian army remained in the areas north and east of the city.

Despite their successful battlefield alliance, a dispute over the division of the conquered territories arose between Bulgaria and Greece as early as December of that year. The dispute worsened, and Greek military units gradually began to push back the smaller Bulgarian detachments, seizing territories previously within the established Macedonian Military Administration. The two sides have different accounts of how the Battle of Angista came about, but its occurrence is a documented fact.

 The Bulgarian troops ceased hostilities on the orders of Bulgaria's prime minister, who feared that the clash would be used as a pretext for an attack on the country from all sides. Despite the cessation of hostilities, Greece still used it as a reason to turn the allied countries against Bulgaria, which subsequently had a catastrophic effect on Bulgaria.
