Greek destroyer Vasilefs Georgios
Vasilefs Georgios () ("King George") was the lead ship of her class of two destroyers built for the Royal Hellenic Navy before the Second World War. Flagship of the navy's Destroyer Flotilla, she participated in the Greco-Italian War in 1940–1941, escorting convoys and unsuccessfully attacking Italian shipping in the Adriatic Sea. While under repair during the Axis invasion of Greece in 1941, "Vasilefs Georgios" sank when the floating drydock that she was in was either scuttled or sunk by German aircraft. The ship was later salvaged and repaired by the Germans who commissioned her into  the "Kriegsmarine" (German Navy) in 1942 as "ZG3", later renaming her as "Hermes". They generally used the ship to escort convoys to and from North Africa and islands in the Aegean Sea. In addition, the Germans occasionally used the ship to lay mines and to ferry troops and supplies. After "Hermes" was transferred to the Central Mediterranean, she sank a British submarine about a week before she was crippled by Allied aircraft in late April 1943. The ship was towed to Tunisia and was scuttled as a blockship shortly before the Allies occupied Tunisia in early May. They refloated the  wreck and it was scrapped after the war. Design and description. The "Vasilefs Georgios"-class ships were derived from the British G-class destroyers, modified with German guns and fire-control systems. They had an overall length of , a beam of , and a draft of . They displaced at standard load and at deep load. The two Parsons geared steam turbine sets, each driving one propeller shaft, were designed to produce using steam provided by three Admiralty three-drum boilers for a designed speed of . During her sea trials on 30 October 1938, "Vasilefs Georgios" reached a speed of from , although her  armament was not yet installed. The ships carried a maximum of of fuel oil which gave a range of at . Their crew consisted of 162 officers and crewmen. Unlike her sister ship , "Vasilefs Georgios" was fitted out to accommodate an admiral and his staff. The ships carried four SK C/34 guns in single mounts with gun shields, one pair each superfiring forward and aft of the superstructure. Her anti-aircraft (AA) armament consisted of four guns in four single mounts amidships and two quadruple mounts for Vickers AA machineguns. The "Vasilefs Georgios" class carried eight above-water torpedo tubes in  two quadruple mounts. They had two depth charge launchers and a single rack for their 17 depth charges. Construction and service. In Greek service. The "Vasilefs Georgios"-class ships were ordered on 29 January 1937 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. "Vasilefs Georgios" was laid down at Yarrow & Company's shipyard in Scotstoun, Scotland, in February 1937, launched on 3 March 1938, and commissioned on 15 February 1939 after she had  her armament installed in Greece. Pending the completion of the light cruiser, the ship served as the flagship of the Destroyer Flotilla, under Commander ("Antiploiarchos") Pyrros Lappas. After the sank the elderly protected cruiser 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. 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. 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 . In German service. 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 AA guns in single mounts. Two torpedo tubes were possibly removed as well. The ship also received German mine rails, radios and a "S-Gerät" sonar. Her crew now consisted of 10 officers and 215 sailors. 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 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 to Salamis on 19–20 August. "ZG3" was then renamed "Hermes" two days later. 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. On 16 November "Hermes" assisted in the sinking of the Greek submarine . 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. 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 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.
