The Vasilefs Georgios-class ships were ordered on 29 January 1937[2] as part of a naval rearmament plan that was intended to include one light cruiser and at least four destroyers, one pair of which were to be built in Britain and the other pair in Greece.[7] Vasilefs Georgios was laid down at Yarrow & Company's shipyard in Scotstoun, Scotland, in February 1937, launched on 3 March 1938,[2] and commissioned on 15 February 1939 after she had her armament installed in Greece.[8] Pending the completion of the light cruiser, the ship served as the flagship of the Destroyer Flotilla,[6] under Commander (Antiploiarchos) Pyrros Lappas.[9]

After the Italian submarine Delfino sank the elderly protected cruiser Elli in a sneak attack on 15 August 1940 off the island of Tinos, Vasilefs Georgios and her sister were sent to Tinos to escort the merchant ships there home.[2] During the Greco-Italian War she escorted convoys and participated in raids against Italian lines of communication in the Strait of Otranto on the nights of 14/15 November 1940 and 4/5 January 1941 that failed to locate any ships. The sisters ferried the Greek gold reserves to Crete on 1 March.[6][2]

After the German invasion of Greece on 6 April, the sisters began to escort convoys between Greece and Egypt via Crete. While anchored in Sofiko Bay in the Saronic Gulf on 12–13 April, Vasilefs Georgios was attacked by German aircraft and badly damaged by near-misses that caused extensive flooding. She managed to reach the Salamis Naval Base despite a severe list where she was drydocked. On 20 April, the floating drydock was scuttled by the Greeks and sank with the unrepaired destroyer still inside it.[10][Note 2]

The Germans nonetheless were able to raise and repair her, and commissioned her into the Kriegsmarine as ZG3 on 21 March 1942, under the command of Commander (Fregattenkapitän), later Captain (Kapitän zur See), Rolf Johannesson. German alterations were not numerous: they reduced her 37 mm guns to a single pair and exchanged her anti-aircraft machineguns for five 2-centimetre (0.8 in) AA guns in single mounts. Two torpedo tubes were possibly removed as well.[13] The ship also received German mine rails, radios and a S-Gerät sonar. Her crew now consisted of 10 officers and 215 sailors.[14]

After working up, ZG3 was declared operational on 30 May, although her first convoy escort mission, scheduled for 1 June, was cancelled. On 24–25 June, she helped to escort a small troop convoy to Souda Bay, Crete, returning to Piraeus, Greece, two days later. On 2–3 July, the ship helped to lay a minefield off the island of Syros. During the rest of the month, ZG3 escorted two convoys between Greece or Crete and North Africa and received a brief overhaul in the middle of the month. The ship escorted the damaged German submarine U-97 back to Salamis on 5 August. Her next convoy to Tobruk, Libya, was interrupted by the British Operation Pedestal to Malta in the middle of the month and she then towed the damaged submarine U-83 to Salamis on 19–20 August.[15] ZG3 was then renamed Hermes two days later.[13] Over the next several months, the ship escorted convoys between Greece, Crete and Tobruk, interrupted by occasional missions to cover a minefield being laid. Later that month her boilers were cleaned and her 37 mm guns were upgraded. Upon her return to duty on 23 October, she resumed escort work, only adding the Dardanelles and various islands in the Aegean and Dodecanese to her destinations.[16] On 16 November Hermes assisted in the sinking of the Greek submarine Triton.[17] Her propulsion machinery was overhauled at Salamis from 20 January 1943 to 19 February and she resumed her convoy escort missions until the end of March. During this time, none of the ships that she escorted were lost.[18]

With Axis forces confined to northern Tunisia by March, the Kriegsmarine ordered Hermes to transfer to Southern Italy on 30 March to protect the supply lines to Tunisia. Now under the command of Fregattenkapitän Curt Rechel, she arrived at Salerno, Italy, on 4 April. The ship laid a minefield south of Sicily with a group of Italian destroyers on 19–20 April. The following day, she detected the British submarine Splendid and drove it to the surface after 45 minutes of depth-charging, rescuing 20 survivors before the submarine sank. Together with two Italian destroyers, Hermes ferried troops and supplies to Tunisia on 25–26 April. Three days later, she made another supply run with two Italian destroyers, but they were attacked by Allied aircraft off Cape Bon. The two accompanying Italian destroyers were sunk and Hermes had her propulsion machinery crippled by near misses. She was towed to La Goulette, the port of Tunis, and scuttled at the harbor entrance as a blockship on 7 May. Several crewmen were killed in the fighting in Tunis the next day, while the others were either captured by the Allies or evacuated to Trapani, Sicily. Rechel had left for Sicily on the 7th, allegedly to report on the loss of his ship. The Allies refloated the wreck to clear the harbor and it was scrapped after the war.[18]
