HMS Hornet was an Acheron-class destroyer of the Royal Navy that served during the First World War and was sold for breaking in 1921.

[5] On 24 January 1915, the First Destroyer Flotilla — including Hornet — were present at the Battle of Dogger Bank, led by the light cruiser Aurora.

[9] In 1917, the Third Battle Squadron was sent to the Mediterranean, where they took part in the 1918 Naval campaign in the Adriatic, including enforcing the Otranto Barrage.

Both British ships turned away, making smoke, with the intention of drawing the enemy south, but Hornet took a hit in the forward shell room and magazine, starting fires in both compartments and causing an explosion.

Jackal turned to the east, but after approximately 15 minutes of firing, Herkner in Triglav broke off the engagement, reasoning that the alarm had certainly been raised.

[10] Hornet was seriously damaged, and Jackal had lost her mainmast, but the appearance of Allied reinforcements had driven the Austrians back to Cattaro (now Kotor in Montenegro).
