SMS Triglav[Note 1] was one of six Tátra-class destroyers built for the kaiserliche und königliche Kriegsmarine (Austro-Hungarian Navy) shortly before the First World War.

Completed in August 1914, the ship participated in an unsuccessful attempt to recapture a small island in the Central Adriatic Sea from the Italians in July 1915.

In November and early December Triglav was one of the ships conducting raids off the Albanian coast to interdict the supply lines between Italy and Albania.

[2] The main armament of the Tátra-class destroyers consisted of two Škoda Works 10-centimeter (3.9 in) K10 guns, one each fore and aft of the superstructure in single mounts.

[4] The Tátra-class ships did not play a significant role in the minor raids and skirmishing in the Adriatic in 1914 and early 1915 between the Entente Cordiale and the Central Powers.

[6] The Kingdom of Italy signed a secret treaty in London in late April 1915 breaking its alliance with the German Empire and Austro-Hungary and promising to declare war on the Central Powers within a month.

They encountered and sank a small cargo ship and a motor schooner carrying flour for Serbia; four Italian destroyers were unable to intercept them before they reached friendly territory.

At 07:30 he ordered four of his destroyers into the harbor to sink the cargo ship and two schooners anchored there while Helgoland engaged the coastal artillery defending the port.

He radioed for assistance at 10:35 and was informed an hour later that the armored cruiser SMS Kaiser Karl VI and four torpedo boats were en route to support him.
