HrMs K IX (Lt.Cdr. P.G. de Back, RNN) departed Surabaya together with HrMs K XI (Lt.Cdr. A.H. Deketh, RNN), HrMs K XII (Lt.Cdr. H.C.J. Coumou, RNN(R)) and HrMs K XIII (Lt.Cdr. M.A.J. Derksema, RNN) (this is the 2nd Dutch submarine division) with the orders to patrol in Strait Karimata and Strait Gaspar.

Deketh, RNN) and HrMs K XII (Lt.Cdr. H.C.J. Coumou, RNN(R)) were ordered to proceed Northwards. K XI was ordered to patrol off the Natuna Islands. The other three submarines were ordered to patrol off the Badas Islands.

K IX however developed engine problems and was forced to return to Surabaya for repairs.


Submarine HNMS K X ()


8 Dec 1941
HrMs K X is put into commission from reserve with the crew of HrMs K IX that returned to Surabaya for repairs. Lt.Cdr. P.G. de Back, RNN is in command. As K X was not in a good state she was initially assigned for the local defence of Surabaya.

25 Dec 1941
HrMs K X (Lt.Cdr. P.G. de Back, RNN) departed Surabaya to attack Japanese warships in Davao Gulf, Philippines.

30 Dec 1941
HrMs K X (Lt.Cdr. P.G. de Back, RNN) is ordered to proceed to Tarakan, Borneo, Netherlands East Indies instead of Davao Gulf. She had to proceed to Ambon first for fuel and distilled water.

31 Dec 1941
HrMs K X (Lt.Cdr. P.G. de Back, RNN) arrived at Ambon, Netherlands East Indies.

1 Jan 1942
HrMs K X (Lt.Cdr. P.G. de Back, RNN) departed Ambon for Tarakan.

8 Jan 1942
HrMs K X (Lt.Cdr. P.G. de Back, RNN) arrived at Tarakan for distilled water for the battery and fresh supplies. Also small repairs were carried out.

9 Jan 1942
When leaving Tarakan to take up a patrol position off that place HrMs K X (Lt.Cdr. P.G. de Back, RNN) is forced to return with a defective compressor of her port diesel engine. The compressor had to be landed as it could not be repaired on board.

10 Jan 1942

Due to Japanese air attacks HrMs K X (Lt.Cdr. P.G. de Back, RNN) retired about a mile up the Kali river and places herself on the bottom of the river.

In the afternoon the engineer officer was sighted in a small rowing boat. K X surfaced and took him on board. The compressor was still not repaired but he informed Lt.Cdr. de Back that a Japanese landing force had arrived and that the had to try to escape to Surabaya on one engine.

In the late afternoon K X therefore set course to escape through a gap in the minefield. This had to be done in daylight as the gap was small and accurate navigation therefore was essential. While doing so K X was attacked by a Japanese aircraft. A bomb was dropped and K X was strafed by machine gun fire causing minor damage to the ships hull. As soon as clear of the minefield and in deep enough water K X submerged. During the night K X slipped past the Japanese force. Meanwhile several serious defects had occured.

19 Jan 1942
After a very difficult passage on her only 'serviceable' diesel engine HrMs K X (Lt.Cdr. P.G. de Back, RNN) arrived at Surabaya. During daylight hours K X submerged to allow the engine room staff to conduct repairs to this engine to keep it going.

24 Feb 1942
HrMs K X (Lt.Cdr. P.G. de Back, RNN) departed Surabaya to patrol to the North of Madura. However she returned later the same day with, yet again, a defective compressor.

28 Feb 1942
HrMs K X (Lt.Cdr. P.G. de Back, RNN) departed Surabaya to patrol off the North Coast of Java near Lasem.

During the late afternoon and evening K X is twice detected by Japanese destroyers and depth charged and shelled. Some damage was inflicted on the submarine but the material state of K X was very bad and several leaks occured making depth control very difficult.

1 Mar 1942
HrMs K X (Lt.Cdr. P.G. de Back, RNN) returned to Surabaya for repairs.

2 Mar 1942
HrMs K X (Lt.Cdr. P.G. de Back, RNN) is scuttled at Surabaya. She was in her current state not able to evacuate to Australia.
