Vasilissa Olga (Greek: ΒΠ Βασίλισσα Όλγα) was a Greek destroyer of the Vasilefs Georgios (modified G) class, which served with the Royal
Hellenic Navy during the Second World War, becoming its most distinguished and successful ship until her loss in 1943. She was named after
Queen Olga of Greece, the wife of King George I, and was the second ship to bear this name.
Built by Yarrow & Company (Scotstoun, Scotland), along with her sister ship, the Vasilefs Georgios, she was the most modern ship of the Greek
Navy at the outbreak of the Second World War. She participated in the naval operations of the Greco-Italian War, in convoy escort duty and in the
first and third naval raids against Italian shipping in the Strait of Otranto (14–15 November 1940, and 4–5 January 1941).
After the German invasion of Greece, along with several other ships, she escaped to Alexandria in May 1941. She was assigned the British pennant
number H 84, and after undergoing modernization in Calcutta (November-December 1941), she returned to active duty in the Mediterranean Sea.
Under her captain, Lt. Cmdr. G. Blessas, she enjoyed several successes:
• On December 14, 1942, she sank the Italian Adua-class submarine Uarsciek (620 tons) off Malta, along with the British destroyer HMS
Petard.[1]
• On January 19, 1943, Olga, along with the British destroyers HMS Pakenham and HMS Nubian, intercepted and sank the Italian transport ship
Stromboli (475 tons) off the Libyan coast.
16 • On June 2, 1943, Olga and the British destroyer HMS Jervis sank the Italian Spica class torpedo boat Castore (ca. 790 tons) off Cape Spartivento.
Olga also participated in the capture of Pantelleria and the Allied invasion of Sicily. During the Allied operations during the Dodecanese Campaign
in the Aegean Sea in September 1943, together with the British destroyers HMS Faulknor and Eclipse, she sank a German convoy, consisting of
the transports Pluto (2,000 tons) and Paolo (4,000 tons), near Astypalea. During the Battle of Leros, she transported members of the Long Range
Desert Group to the island, but on September 26, she was attacked and sunk by 25 Junkers Ju 88 bombers in the Gulf of Lakki in Leros. Cmdr.
Blessas, 6 officers and 65 other members of the crew perished with the ship. A monument has been erected in Lakki in honour of the ship.
