6 Oct 1944
USS Besugo (Cdr. T.L. Wogan, USN) damaged a Japanese patrol vessel with gunfire in the North Pacific. The action had to be broken off when both 20mm guns jammed. Besugo was lightly damaged by return fire from the Japanese. Also two of her crew were injured by the emeny machine gun fire.

Before engaging the enemy with gunfire three torpedoes were fired but these either missed or ran under.

(All times are zone K, -10)
1931 hours - In position 30°03'N, 151°11'E obtained radar contact bearing 282°(T), range 5000 yards. Commenced tracking and approach.

2102 hours - Fired three torpedoes from 1250 yards at the target, an enemy picket boat. No hits were obtained and it is thought the torpedoes might have run under.

2228 hours - In position 30°02'N, 151°04'E engaged the target with the 5" gun and with 20mm from a range of 1400 yards. 5" gunfire was ineffective on account of swell and visibility. Closed to 900 yards at which range the 20mm fire became effective and several hits were obtained on the after part of the target. The enemy returned fire with a light machine gun.

2233 hours - Both 20mm guns jammed. This was the signal for the target to spring to life and he closed the range to 500 yards and opened up, besides the light machine gun fire, with a .50cal machine gun. We opened the range and withdrew to look the situation over. Eventually decided to break off the action.

15 Oct 1944
USS Besugo (Cdr. T.L. Wogan, USN) sighted a Japanese task force. This task force was made up of the heavy cruisers Ashigara and Nachi, light cruiser Abukuma and destroyers Akebono, Kasumi, Ushio, Shiranui, Wakaba, Hatsushimo and Hatsuharu.

0830 hours - The task force went out of sight on a base course of 140°(T), speed 18 knots.

Following this contact a report was sent to CumSubPac.

16 Oct 1944

Between 0500 hrs and midnight, USS Besugo (Cdr. T.L. Wogan, USN) makes three separate attacks against a convoy, in the last of which she torpedoed and sank the Japanese landing ship T 151 (870 tons) off the northern tip of Palawan Island in position 11°22'N, 119°07'E.
Cdr. Wogan also claims the sinking of a 5000-ton oiler with one hit out of four torpedoes fired and of a 3000-ton lighter or barge also with one hit out of four torpedoes earlier the same day. Both these attacks were on the surfac. The claimed sinkings are so far unconfirmed.

(All times are zone H, -8)

0504 hours - Went to battle stations. Commenced a surface approach. Dawn will break in 30 minutes.

0519 hours - Range was now 2500 yards. The target was identified as a medium tanker making slow speed on a steady course, apparently all alone. Frequent careful all around searches with radar revealed nothing.

0521 hours - In position 11°40'N, 119°36'E commenced firing four torpedoes from a range of 2100 yards. Obtained one hit about amidships and the target was enveloped in flames that rose to a height of 700-800 feet.

0525 hours - As Besugo turned away, radar picked up another target pip at about 1500 yards, astern of where the first target sank. Tracked this pip and then closed. In the growing light of dawn the target was seen to be a big barge which must have been towed by the tanker. The target was stopped.

0530 hours - In position 11°44'N, 119°32'E fired two torpedoes from 1800 yards. One hit was obtained in the stern of the barge. The barge then started to sink by the stern.

0534 hours - Fired another two torpedoes. No hits were obtained. No further torpedoes were fired as the target was sinking.

-------------------------------------------------------

2037 hours - Made radar contact bearing 327°(T), range 18000 yards. Commenced tracking. Contact was lost five minutes later.

2054 hours - Another radar contact bearing 300°(T), range 12000 yards. Commenced tracking this latest contact. The target was zigzagging on a base course of 210°(T), making about 14 knots. As Besugo was on his beam commenced working ahead.

2133 hours - Turned in to attack.

2138 hours - In position 11°38'N, 119°25'E fired four torpedoes but all missed. The target was now seen for the first time and was thought to be a tanker.

2331 hours - Fired no.9 tube from 1240 yards. It missed.

2344 hours - Fired no.10 tube from 1000 yards. Again no hit. Now out of torpedoes cleared the area. Due to the bad visibility gun action was out of the question.
