Georgios Averof (Greek: Θ/Κ Γεώργιος Αβέρωφ) is a modified Pisa-class armoured cruiser built in Italy for the Royal Hellenic Navy in the first decade of the 20th century. The ship served as the Greek flagship during most of the first half of the century. Although popularly known in Greece as a battleship (θωρηκτό), she is in fact an armored cruiser (θωρακισμένο καταδρομικό), the only ship of this type still in existence.[2]
The ship was initially ordered by the Italian Regia Marina, but budgetary constraints led Italy to offer it for sale to international customers. With the bequest of the wealthy benefactor George Averoff as down payment, Greece acquired the ship in 1909. Launched in 1910, Averof arrived in Greece in September 1911. The most modern warship in the Aegean Sea at the time, she served as the flagship of admiral Pavlos Kountouriotis in the First Balkan War, and played a major role in the establishment of Greek predominance over the Ottoman Navy and the incorporation of many Aegean islands to Greece.
The ship continued to serve in World War I, the Greco-Turkish War of 1919–1922, and the interwar period, receiving a modernization in France in 1925 to 1927. Following the German invasion of Greece in April 1941, Averof participated in the exodus of the Greek fleet to Egypt. Obsolete and prone to mechanical breakdowns, she nevertheless spent the next three years as a convoy escort and guard ship in the Indian Ocean and at the Suez Canal. In October 1944, she carried the Greek government in exile back to liberated Athens, after the withdrawal of the German army.
In 1952, she was decommissioned, before being moved to Poros, where she was berthed from 1956 to 1983. From 1984 until today, she has been reinstated on active duty as a museum ship in the Naval Tradition Park in Palaio Faliro, Athens. After maintenance in late 2017, she was towed to Thessaloniki, where she was displayed to the public for several weeks.
History
Construction and arrival in Greece

At the beginning of the 20th century, Greece decided to reinforce its fleet, whose ships were fast becoming obsolete due to the rapidly advancing naval technology of the era. The navy procured eight destroyers (then a relatively new type of ship) between 1905 and 1907, but the most important addition was the armored cruiser Georgios Averof. Like her Italian sisters Amalfi and Pisa, she was being built at Orlando Shipyards, Livorno, Italy. When the Italian government cancelled the third ship of the class due to budgetary concerns, the Greek government immediately stepped in and bought her with a one-third downpayment (ca. 300,000 gold pound sterling), the bequest of a wealthy Greek benefactor, Georgios Averof, whose name she consequently received.


The Averof was fitted out with a combination of Italian engines (Ansaldo type), French boilers (Belleville type), British guns (Armstrong type), and German generators and armor (Krupp type).[3] The most discernible difference between the cruiser and her Italian sisters was the shape of her six gun turrets. The Averof encased her British-built guns in rounded pillbox-form housings with convex roof plates. She was also fitted out with a foremast, which her sister-ships did not receive until after the start of the First World War. Her stern was also equipped with a balcony (paying homage to the old wooden sailing ships of the Middle Ages and of the Greek War of Independence) and a large ornate nameplate with the coat of arms of the Kingdom of Greece. She was even fitted out with a very small Orthodox chapel inside her (initially designed to be a storehouse for ammunition), dedicated to Saint Nicholas, the Patron Saint of sailors. And she was finally equipped with a steel ram in her inverted bow (paying homage to the ancient triremes). Such was the urgency of the Greek Navy to see the ship in service, that they accepted her with a gouge inside one of the 7.5-inch (191 mm) gun barrels. This had been caused by the slip of a rifling tool, but Armstrong Whitworth‘s chief ordnance engineer correctly judged the defect as inconsequential to the weapon’s performance and safety.
The Averof was launched on 12 March 1910. She would be the last commissioned armored cruiser in the world, a class of warship that had already been rendered obsolete by the battlecruiser. Her first captain, Ioannis Damianos, took command on 16 May 1911, and the Averof immediately sailed to England for the Coronation Naval Review of King George V. While there, she would also receive the first load of ammunition for her British-built guns. The stay in England was troubled by running aground at Spithead on 19 June, which forced her into drydock. While waiting for repairs, her crew was involved in a large brawl with the locals, caused by their unfamiliarity with the mould found on edible blue cheese. Captain Damianos was deemed inadequate to maintain discipline, and replaced by the esteemed taskmaster, Pavlos Kountouriotis. During the journey home, Captain Kountouriotis thoroughly trained his crew, with the exception of gunnery practice, as ammunition was limited to special deliveries from Britain. The Averof finally reached Faliro Bay, near Athens, on 1 September 1911. At that time, she was the most modern and powerful warship in the navies of the Balkan League or the Ottoman Empire. And because of this, the Greek people started calling her a battleship.
Balkan Wars

With the outbreak of the First Balkan War in October 1912, Kountouriotis was named rear admiral and commander-in-chief of the Hellenic Royal Navy. Averof, under Captain Sofoklis Dousmanis, served as the flagship of the fleet, and she took part in the takeover of the islands of the northern and eastern Aegean. During the naval battles at Elli (3 December 1912) and Lemnos (5 January 1913) against the Ottoman Navy, she almost single-handedly secured victory and the undisputed control of the Aegean Sea for Greece. In both battles, due to her superior speed, armor and armament, she left the battle line and pursued the Turkish Fleet alone. During the Battle of Elli, Kountouriotis, frustrated by the slow speed of the three older Greek battleships, hoisted the Flag Signal for the letter Z which stood for “Independent Action”, and sailed forward alone, with a speed of 20 knots (37 km/h) against the Turkish fleet. Averof succeeded in crossing the T of the Turkish fleet and concentrated her fire against the Ottoman flagship, thus forcing the Ottoman fleet to retreat in disorder. Likewise, during the Battle of Lemnos, when the older battleships failed to follow up with Averof, Kountouriotis did not hesitate to pursue independent action.

In each battle the ship suffered only slight damage, while inflicting severe damage to several Turkish ships. These exploits propelled her and her Admiral to legendary status in Greece. After the Battle of Lemnos, the crew of Averof affectionately nicknamed her “Lucky Uncle George”, while the Turks dubbed her “Şeytan papor” (“The Devil’s Ship”). It is a notable fact that, due to the aforementioned need to conserve ammunition which had to be secured from Britain, Averof fired her guns for the first time during the Battle of Elli.
Georgios Averof is credited with successfully closing the Aegean Sea to Ottoman transports bringing fresh troops and supplies to the front during the First Balkan War. This success had a concrete impact on the land action where the Ottoman forces suffered decisive defeats. It is hypothesized that in the lack of such decisive control of the sea by the Greek Navy, the Ottoman Empire might have reinforced its forces on the Balkan Peninsula and therefore fared better in the war.[4]
