The Battle of the Crna bend was a two-month-long battle between the Bulgarian and Entente armies. The battle took place in the Macedonian Front during the First World War Allied Monastir Offensive in October and November 1916. After extremely heavy fighting and severe casualties on both sides, the Bulgarians retreated from Bitola on the 19 November and took positions at 5 km to the north defeating all later attacks from there. However, the Entente entry in Bitola had no strategic value.
