(All times are zone -8)
0336 hours - Sighted silhouette bearing 292°. Went to action stations.

0337 hours - Dived. Asdic reported propellers bearing 300°. Changed course to intercept.

0345 hours - Fired four torpedoes from 1500 yards at what might have been an enemy patrol vessel. No hits were obtained. No pinging was heard and no counter attack followed. (5)

9 Jan 1945
HrMs O 19 (Lt.Cdr. J.F. Drijfhout van Hooff, RNN) torpedoed and sank the Japanese auxiliary gunboat Shinko Maru No.1 (935 GRT, built 1938) off Tandjung Puting, Borneo in position 03°46'S, 111°54'E. The O 19 however is heavily damaged by depth charges from the submarine chaser CH-5 and forced to abandon her patrol.

(All times are zone -8)
1653 hours - Sighted mast bearing 064°.

1710 hours - Plot suggested enemy's course 270°.

1732 hours - Sighted smoke bearing 088°. The masts of the previous contact were now nearly in line. The new contact was later seen to be a submarine chaser. The first contact was a small merchant vessel.

1849 hours - Fired three torpedoes at the merchant vessel from 800 yards. Went deep on firing but hit bottom at 11 fathoms. One torpedo explosion was heard followed by breaking up noises several minutes later.

1903 hours - Tried to get off the bottom.

1909 hours - At periscope depth. The merchant was not seen and must have sunk. The escort however was only 400 yards away and turned towards. Went to the bottom again.

1911 hours - The submarine chaser went overhead but dropped nothing.

1922 hours - Three depth charges but these were quite some way off. Decided to remain on the bottom.

2037 hours - The enemy suddenly raced overhead and dropped five depth charges, very close. They caused serious damage. A hail of light bulbs came down, lights went out. Water leaks on several places. A short circuit burnt itself out in the control room. But worst of all in the engine room the airconditioning plant started leaking carbondoxide into the boat. The stern compartment and engine room had to be evacuated. Closed all W/T doors. The fumes leaked into the control room and it had to be evacuated also.

2230 hours - A selection of engine room personnel was fitted out with DSEA sets.

2242 hours - Blow ballast and went to the surface. It was very dark but shapes of two ships were seen at a range of 1500 yards. Dived again.

2300 hours - With great effort the W/T door to the engine room could be opened. There was water to the deckplates. Water was still pouring in through valves that had been opened through the shock of the explosions. These were closed and water was being pumped out.

2328 hours - Both engines reported ready.

2330 hours - Surfaced and cleared the area at high speed on both engines. Damage was investigated during the night. The result was that it was impossible to remain on patrol. (5)
