Today and tomorrow, one group of Task Force 38 fuels each day.

Submarines

First report from north Yellow Sea subs comes from BLUEFISH (SS 222)
whose only results to date are a small freighter sunk.

In the Kuriles, PIPER (SS 409) reports hunting not good. A sweep
was made of the area where most contacts were made in 1944 without results.
Some shipp ng was seen close along the Kurile chain.

From the same area, PLAICE (SS 390) reports adding a damaged
trawler to her bag.

At 0050(K) JACK (SS 259), on lifeguard station off Kyushu, had a
raaar contact with an unknown ship with 10 CM radar. The submarine trailed
at maximnm speed for five hours, during which time she was able to reduce
the bearing of her target from 125 to 120. There is a possibility that this
was an enemy surface ship on course 150, speed 20. Last contact at 29-55,
132-50.

Some increased evidence of submarine activity. DEVILFISH (SS 292)
on patrol off BUNGO SUIDO, attacked and missed a Jap sub with a midget on
deck yesterday evening.

The Jap sub was on course 130.

Aircraft barrier patrols have been ordered and AS vessels will be
stationed north of EmIRCETC-MARIANAS shipping lanes.

Yesterday morning a VIL weather plane sighted a 10 to 15 miles oil
slick at 11-10N 133-151 with much debris scattered through the slick.
Though the plane circled several times at 1000 feet no survivors, boats
or large weeckage was observed.

This is close to the position of a periscope
sighting the day before.

ASW Group had negative results in search around area plane attack on sub reported yesterday. However, there was a large oil slick 3 by 1k miles observed in the area which may indicate sinking, perhaps of one of the midgets. No debris was found.

Yesterday afternoon, 150 miles to the south of this contact, ANTARES (AaS 3) was attacked by possibly two submarines. SPROSTON (DD 577) proceeded to the scene and made several attacks on sonar and sight contacts.

2 periscopes were seen, 1 of a fleet submarine, the other of a midget. Midget sub was attacked by gunfire and disappeared. Several large oil slicks were seen, but again no debris.

lastnight shortly before midnight, a merchant vessel reported seeing a submarine on the surface at 2000 yards distance in bright moonlight and good visibility. The sub continued on its course to the southwest and took no hostile action.

5 hours later another merchiaat ship reported a submarine but gives no details. These contacts considered sufficiently good to Justify starting ASN operations.
Another contact was made 300 miles east of IEYTE.
