and sinks the 7,176-ton American "Liberty" ship JOHN STRAUB en route from Port

sinks by the bow at 54-23N, 162-35W. 
25 April 1944:
50 miles SW of Cherikof Island, Aleutians. Lt Walter D.
Jenckes' USS GILMORE (DE-18) and EDWARD C. DALEY (DE-17) are escorting tanker
FRANK G. DRUM and the converted Liberty-ship CHRISTOPHER GREENUP from Dutch
Harbor to Kodiak, Alaska. At 2230, GILMORE's SG radar picks up a surfaced
submarine at 8,000 yards and she detaches to investigate the contact. At 4,000
yards, after being challenged with blinker, the "pip" disappears. GILMORE soon
acquires a sound contact at 2,600 yards. In the next hour, Jenckes lays down
three separate barrages of Mark 10 "Hedgehogs", each of twenty-four projector
charges, but without result.
26 April 1944:
At 0027, GILMORE drops a pattern of 13 depth charges,
but again without result. At 0107, Jenckes drops another pattern of 13
projectiles. At 0112, GILMORE's efforts are rewarded by a heavy underwater
explosion that rocks the destroyer escort. The submarine - probably I-180 -
sinks at 55-10N, 155-40W.

Naval Air Station observe a thick oil slick measuring about one square mile in

Toshio (66) was killed in that attack. In reality he died in the hospital three
 I-180 is sometimes credited with sinking the Soviet steamer PAVLIN
VINOGRADOV, en route from Vancouver to Vladivostok on 22 April. This is not
confirmed by existing Japanese records; in fact several contemporary sources
suggest that the steamer was lost to an onboard acetone explosion.
Thanks go to Dr. Higuchi Tatsuhiro of Japan.
