2325 hours - Range to the chasing escort was now 2100 yards.

2329 hours - Heard and felt six tremendous explosions about 10 seconds apart which shook Baya violently. These were possibly depth charges which exploded in shallow water.

2333 hours - The minelayer now turned away. Informed USS Lagarto that we had been driven off by gunfire.

2345 hours - Range was now opening fast. Secured from battle stations.

3 May 1945

2200 hours - The convoy was identified as the came convoy that we attacked last night. Enemy course was initially 030°(T) but after a few minutes of circling around the convoy proceeded due south.

2215 hours - Proceeded at full speed on an end around for a port flank attack.

2240 hours - Making good progress up the convoys port quarter. The convoy has suddenly changed course to his left to 050°(T). Continued to cross ahead at full speed.

The convoy changed course abruptly to 340°(T). These can not be zigs, the convoy is obviously alerted by our radar and is taking evasive actions based apparently on the change of bearing of our 10cm radar.

2300 hours - Continuing down the convoy's starboard flank to gain a favourable attack position. The convoy has now eased around to small zigs on a rough base course of 050°(T). We were now using our SJ radar only for 5 seconds every two minutes.

2347 hours - The convoy was zigging on a base course of 060°(T) at a speed of 9 knots. Having sent USS Lagarto contact reports almost half hourly with no receipt, decided to make the attack alone. Manned battle stations.

2358 hours - Baya was now in a fine position on the convoy's starboard bow expecting a zig away. Commenced surface approach at 14 knots.

0013 hours - Observd the targets to turn away completely while the nearest escort turned towards.

0015 hours - One explosion was reported from below but nothing was heard or seen on the bridge.

0020 hours - Secured from battle stations.

0030 hours - Pulling awayfrom the escort. Decided to try another starboard flank attack after shaking off the escort. Manned battle stations.

0037 hours - The escort was still chasing Baya on the port quarter. The main target group was now on course 020°(T).

0053 hours - The convoy made a radical course change to the north-west.

0110 hours - Changed course to 020°(T) at full speed to shake off the escort, get ahead of him and then to come in for the second attack.

0118 hours - Moonrise. The convoy had now changed course to 320°(T) to keep us astern. The escort was between us and the main group so Baya was unable to close for another attack.

0134 hours - Lost contact with the convoy. Secured from battle stations. Changed course to get ahead on the possible convoy track at slow speed. However, the convoy was not seen again.

13 May 1945

0553 hours - Commenced surface approach from the seaward and starboard flank of the convoy at 14 knots. All torpedoes were set to 4 feet.

0559 hours - Slowed to 12 knots to reduce the wake. The convoy was by now seen to be made up of an engine aft large freighter which looked quite new. She was heavily laden. A medium or small transport was following about 1500 yards astern. A third ship was on the starboard quarter of the large freighter, this ship was thought to be a large minelayer.

0605 hours - In position 06°31'S, 111°19'E started firing a full bow salvo of six torpedoes at the large freighter.

0610 hours - After swinging around fired two stern torpedoes at the medium to small transport. Went ahead flank fter firing these last two torpedoes.

1907 hours - In position 06°27'S, 117°19'E sighted smoke through the high periscope, bearing 088°(T). This contact developed into five small targets on a base course of 255°(T) at a speed of 7 knots. Commenced tracking from ahead.

2127 hours - Manned battle stations.

2150 hours - With the range now down to 3500 yards the targets finally became sufficiently visible to be identified as three Sugar dogs (400-500 ton), one 100 ton submarine chaser and one other patrol craft. Withheld fire as the targets were not large enough for torpedoes.

2153 hours - Reversed course and pulled clear leaving the targets alerted and maneuvering in tight circles. Resumed tracking the targets while awating the arrival of the USS Capitaine. Contemplate suggesting a gun shoot.
