The most dramatic event in the early months of the Continuation War was the sinking of the armored ship Ilmarinen. Ilmarinen drove into mines south of Utö on September 13, 1941.
The danger of mine on the renewed route was estimated to be so low that it was ventured without escorts.
On the sides of both armored ships were paravans, their own guard clearers. Their purpose was to prevent destructive explosives from drifting into the sides of ships by directing mines outside them.
After a brisk couple of hours, at about 8.30 pm Ilmarinen was at his turning point. At the time, the other screen had picked up a mine, probably two.
Two consecutive, powerful explosions followed. Ilmarinen quickly leaned to the left and fell to his side in less than a minute, spinning upside down. In seven minutes the ship had sunk.
The mines had hit the bottom of the ship at the engine room. The hull of the ship was compartmentalized, but the engine room was a uniform space. This allowed water to penetrate quickly from the opening torn by the explosion.
“We bravely watched the last moments of the death struggle of our flagship. Once again, Ilmarinen - as if feeling his strength - raised his bow and slowly sank below the water surface as oil and air bubbles rose as a sign of our ship's last resting place, ”Juvonen described.
Ilmarinen took 271 soldiers with him to the abyss, and 132 men survived. Only Sergeant Hugo Kurppa, who was rescued from the engine room, drowned in January 1945 when the minesweeper Louhe sank. Sailor Juvonen was saved for the second time.
