It also managed to trap the remains of the Army of Vardar in what was left of Albania proper, but were not able to force them to surrender.[1] However, when the war was over, the Great Powers did not award the city to the Kingdom of Montenegro, which was compelled to evacuate it in May 1913, in accordance with the London Conference of Ambassadors. The army's withdrawal was hastened by a small naval flotilla of British and Italian gunboats that moved up the Bojana River and across the Adriatic coastline. International peace keeping force (Scutari detachment) from five countries - Austria-Hungary, Great Britain, France, Italy and Germany - was deployed in the city and kept until the start of WWI.[20] The Kingdom of Montenegro also later took Metohija, an area of Kosovo.
