SS Van Waerwijck was a passenger steamship that was launched in the Netherlands in 1909 and sunk in the Strait of Malacca in 1944.

She spent most of her career with Koninklijke Paketvaart-Maatschappij (KPM, the "Royal Parcel Navigation Company"), based in the Dutch East Indies.

In the Second World War she was sunk as a blockship, but later raised by Japan, who repaired her and renamed her 治菊丸, transcribed into the Latin alphabet as Harugiku Maru.

In 1944 she was carrying Allied prisoners of war when a Royal Navy submarine sank her, killing between 154 and 198 of the people aboard.

[13] On 20 March 1918 President Woodrow Wilson issued Proclamation 1436, authorising the seizure under angary of Dutch ships in US ports.

She was registered in Hong Kong, with the UK official number 142209 and code letters THMS.

The next day, Van Waerwijck's crew scuttled her in the harbour mouth of the Port of Tanjung Priok as a blockship.

[6] The Japanese raised the ship in July 1942, repaired her, renamed her 治菊丸 (Harugiku Maru), and returned her to service.

[6] The Government of Japan appointed the Daido Kaiun shipping company (now part of Mitsui O.S.K.

[17] On 24 June 1944, Japanese trucks took several hundred Allied PoWs from Gloe Gloer prisoner-of-war camp on Sumatra to the Port of Belawan, where they were embarked on Harugiku Maru.

[22] At 09:58 hrs on 26 June the Royal Navy submarine HMS Truculent sighted the convoy.

At 11:12 hrs Harugiku Maru was at position 03°15′N 99°46′E / 3.250°N 99.767°E / 3.250; 99.767 when Truculent fired a spread of four torpedoes from a range of 3,500 yards (3,200 m).

[22] One of the PoWs embarked on Harugiku Maru, RAF Leading Aircraftman Frank Williams, smuggled a pointer dog aboard in a sack.

[25] Judy was a ship's dog who had survived the sinking of the gunboat HMS Grasshopper on 14 February 1942,[26] and spent more than two years in a PoW camp at Medan.

As Harugiku Maru was sinking, Williams pushed Judy out of a porthole, and then separately made his own escape from the ship.
