Battle of Florina

The Battle of Lerin or Battle of Florina or Chegan offensive was an offensive operation of the Bulgarian army during the First World War between 17–28 August 1916 in which they conquered the city of Florina , but failed to take Chegan.

In August 1916 Romania chose to join the war effort on the side of the Entente. The Allies planned a large offensive in the Macedonian Front for the middle of August in order to support Romania's entry in the war and pin down as many Bulgarian forces as possible. The Bulgarian high command suspected an impending offensive and the fighting around Doiran that erupted on 9 August only confirmed these suspicions. On their part the Bulgarians had urged for an offensive in Macedonia since the beginning of the year and now planned a strike with the First Army and Second Army on both Allied flanks.
