H.M.S PERSEUS

John Capes

 The British Submarine “PERSEUS” set-off on 24-11-1941 from Malta for an offensive Patrol mission in the gulf of Taranta in the Adriatic Sea and the Ionian Sea. On 6-12-1941 she struck a mine off the coast of Kefalonia and went down taking with her 60 officers and lower ranked men.  The British crew member (stoker) John Capes was the sole survivor as he managed a daring last minute escape from the sunken submarine. Using a special escape apparatus named DAVIS he performed a "second to none", a superhuman effort to successfully ascent from the Perseus Shipwreck, to the surface of the cold Ionian sea water and also to his survivor...     He swam to the nearest shore of Kefalonia Island, a beautiful island which was then under the Italian occupation.

The Sinking
     On the night of 6 December, 1941, H.M.S. PERSEUS was patrolling the surface of the Ionian Sea between the Greek islands of Kefalonia and Zante. On board the ship appart from its permanent crew, were the British Sailor (stoker) John Capes and the Greek Lieutenant Nicolaos Merlin. It was a dark and windy night. Suddenly a tremendous explosion shattered the submarine from stem to stern. The submarine had hit something, probably a mine. From the crack that was caused by the collision ďn the port fore side and the opened hatch of the conning tower tons of water surged into the vessel. . A few seconds later the submarine is going down in a nosedive along with sixty officers and sailors that are drifted in the cold waters of the Ionian Sea. .

     From the sixty men that were drifted along with the submarine on the seabed of the Ionian Sea, an English rating managed to do something unique in the Navy History. The stoker John Capes was resting at the aft compartment just before the explosion occurred. He was going through some letters, drinking rum. When H.M.S PERSEUS began to sink, the aft compartment did not flood until the submarine touched the bottom of the Ionian Sea.

     Although injured, Capes started to search for other survivors and found three other badly injured stokers, alive in the debris. Without wasting any time, Capes found the Davis Submerged Escape Apparatus and helped his wounded companions to put them on. Then he had to find a way to open the hatch of the aft compartment and that could only be done by balancing the pressure in the compartment with that in the sea. First he lowered the collapsible canvas escape trunk and secured it by lashings to the deck.

Unfortunately when he found the valve he had to use in order to flood the compartment he saw that its spindle was bent and immovable. So he had to find another way to do it otherwise they would be trapped. And he did. He flooded the compartment using the underwater gun, which is under normal circumstances used for sending smoke signals to the surface. Immediately he helped his shipmates to duck down under the water, come up inside the trunk and get out to the sea through the escape hatch. Then he followed the same procedure and began his own ascent from 52 meters depth. Straining through his painful ascent he managed to surface and started looking around for his companions, in vain. No one else had survived the sinking of H.M.S. PERSEUS that became an underwater grave for fifty-nine men.

Despite being badly worn out, Capes summoned up all the energy he had left and started swimming towards the dark mass he could discern in the horizon. After a struggle of many hours with the cold sea he reached to a rocky beach. With great effort he crawled over the rocks to finally get to one of the impressive beaches of Kefalonia Island. Exhausted as he was he lapsed into unconsciousness. 

There he was found by the island inhabitants (Miltiades Xareras and Xaralabos Valianos, two fishermen from the nearest area, Mavrata village, found him) who medically treated and took him into shelter. Having been in good hands for more than 18 months he was helped to escape to safety in Smyrna. John Capes extraordinary survival adventure was difficult  to be taken seriously. No one believed his stories as they seemed too far fetched. As such no one ever understood what this man had really gone through, this was more like a journey from hell to paradise. It had never happened before, for someone to escape from such a depth. Today, 56 years later the Diving Research Team of Costas Thoctarides sheds some light into the mysteries of how the sinking of the HMS Perseus happened.   Unfortunately John Capes is no longer with us so that his daring escape story could be brought to justice, with the verification of his escape...
