Lettens Jan30/05/2012S/S Zyunyo Maru (Junyo Maru)

Owned by Baba Shoji K. K. and built in 1913 by Robert Duncan Co, Glasgow; 5.065 tons; 405x53x27.2ft; 475 n.h.p.; triple expansion engines

On September 18th, 1944, when sailing from Tangjung Priok, Java to Padang, Sumatra , Junyo Maru was unfortunately torpedoed west off Sumatra, Mukomuko by the British submarine HMS TRADEWIND.

Apart from the crew and Japanese guards, there were 1,377 Dutch, 64 British and Australian, and 8 American prisoners of war and 4.200 Javanese slave labourers packed in her holds and on deck, bound to work on the Sumatra Railway Line between Pakan Baru and Muaro.

The ship was fitted with extra decks of bamboo, subdivided into cages to keep the prisoners in. The conditions the prisoners had to live in on board in were absolutely inhuman.

Of this total of 6.500 prisoners, 5.620 lost their lives in the sinking. The 723 who survived, were rescued only to be put to work in conditions, perhaps worse then their comrades who died.

Just like the Wilhelm Gustloff and many others, the Junyo Maru disaster is one of the most forgotten disasters.

Allen Tony28/12/2013Zyunyo Maru SS was a Japanese Government steamer of 5,131 tons built in 1913 by Robert Duncan & Co., Port Glasgow, Yard No 324 for Lang & Fulton, Greenock as the ARDGORM SS. She was powered by a steam triple expansion engine of hp.

In 1917 she was acquired by the Norfolk & North American SS Co. (Furness, Withy), London and renamed HARTLAND POINT.

In 1918 she was acquired by Johnstone Line, Liverpool.

In 1920 she was renamed HARTMORE. In 1921 she was acquired by Anglo-Oriental Nav Co. (Yule, Catto), Liverpool and renamed SUREWAY.

In 1926 she was sold to Japanese owners and renamed JUNYO MARU.

She was taken over in 1938 by the Japanese Government and renamed ZYUNYO MARU.

On the 18th September 1944 she was torpedoed by HMS TRADEWIND on the West coast of Sumatra while carrying PoW´s and Javanese labourers.
Note: The change from Junyo to Zyunjo was due to the adoption of the "Romaji" system of spelling by the Japanese Government in 1937. The word "Junyo' means 'hawk' and the word 'Maru' has been used in ship names in Japan since 1493.
