The purpose of the blockade was stopping Montenegrin reinforces and supplies from reaching the Albanian coast.

During the First Balkan War, the Great Powers decided that the disputed region should be given to the newly independent kingdom of Albania, created as a neutral country under international administration, and they decided to carry out a blockade to reinforce this decision.

[6][7] As Montenegro continued their siege of Scutari, the Great Powers decided to implement the blockade, which was declared on 10 April 1913.

[1] The block initially extended along the Montenegrin-Albanian coast from Bar (now in Montenegro) up to the outlet of the river Drin, near Shëngjin, in present-day Albania.

[2] Pressured by the international blockade, Serbia withdrew its army from Scutari, which was subsequently occupied by a joint Allied ground force.
