(1928-1943) Submarine Y-1 "Katsonis"

Y-1 KatsonisA sister of Y-2 "Papanikolis", Y-1 "Katsonis" was one of only six submarines available to the Greeks in 1940. Despite being an aged submarine by World War II, it was used extensively in war patrols and commando operations in the Adriatic and the Aegean Sea, before being sunk by a German subchaser in 1943.

Laskos spots a sail boat and decides to surface to try to get more information about Simfra. While he is still talking probably to the boat's skipper, what looks like Simfra is spotted in the horizon. Katsonis soon receives optical identification signals from the ship, but it isn't Simfra. It is the German subchaser UJ-2101. Katsonis crash dives, but soon receives depth charges and is forced to resurface. Laskos orders the crew to return fire with the cannon, and after the gunners are killed, he himself takes their place, but is soon killed too, and Katsonis sinks.

An aged submarine, Katsonis was obsolescent by 1940.

Captain Vasileios Laskos
Vasileios Laskos Laskos was born on 17 Sep. 1899 in Elefsina. In 1922, he was a Sub Lieutenant on the torpedo boat Aspis. In September, he leaves his commander on the shore and joins the rebel fleet of the Plastiras movement in Cavo Doro. General Pangkalos takes power militarily, abolishes the monarchy and declares the Second Hellenic Republic. A close supporter of Pangkalos, Laskos stays with him until the Kondylis movement overthrows Pangkalos and sends him to prison. As a collaborator of Pangkalos, Laskos is now relegated to being in charge of only a warehouse of 50 faulty torpedoes. However, Laskos takes on the task to repair these torpedoes and subsequently receives the congratulations of the Minister of Naval Affairs and is rewarded with a trip to England to supervise the purchase of 50 newly ordered torpedoes.

When he returns, he decides to join the submarine fleet. In 1930, at the age of 32, he is assigned to Y-1 Katsonis. After the failed elections of 1933, he is convinced into taking part in the Venizelos movement. On 1 Mar. 1935, he manages to take control of the submarine base and helps the ships to receive their ammunition and escape. When the movement fails on land, the protagonists escape to the then Italian Dodecannese and then Italy. While in Italy, Laskos is charged back home with treason and sentenced twice to death. A year later, they are all pardoned and return to Greece. After being unemployed for a while, he is trusted to build and organise a factory in Elefsina, a project he carries out succesfully.

On October 1940, Laskos returns to active duty, leading a squadron of auxiliaries. When the Germans invade, he tries to escape to the Middle East. He is first caught by the Turks and is returned to Chios, where he hides as a nurse in a clinic. In the Spring of 1942, he tries again and manages to join the Free Greek forces in the Middle East. He wishes to return to the submarines, but he is now already 43 and Vasileios Laskos has missed the last eight years. He convinces fellow Arvanites, Admiral Aleksandros Sakellariou and Captain Panagiotis Konstas to give him command of Katsonis, which was the submarine most in need of repairs. After 7 months of repairs in Port Sudan, Katsonis is now in Port Said for dry docking. There it sinks due to human error. Laskos manages to convince the British to raise it, and a few months later the submarine is operational.

  1. Just to inform that a great research made by "submariner" member in axis history forum:

    Found that the guns are Odero Terni 102/40 so 102mm guns of Italian origin.
