On February 21, 1916 she was sunk near the Albanian port of Durrës by a mine laid by the German U-boat UC-12.

[2] British drifters Hasting Castle and Selina saved 104 men from the water while 33 were killed.

During the war SM UC-12 operated as a minelayer, and undertook 7 patrols in this role.

One of these, the Italian Marechiaro sunk on 21 February 1916 and was listed as a hospital ship.

Since Germany was not at war with Italy at this stage, though Austria was, UC 12, like other German U-boats in the Mediterranean, operated under the Austrian flag.
