Fifth Unit Commendation was issued August, 1998 by COMSUBPAC in Honolulu, HI.

Lost on Patrol:
Lost with a crew of  74 in the Caroline Basin, northwest
of the Admiralty
Islands, Southwest of Rabaul on
March 15, 1943.   Investigations of Japanese records
recovered after the war showed that a submarine was
depth-charged by three Japanese destroyers in that area
on 15 March.  "A great quantity of oil and debris came
to the surface, including manufactured goods inscribed
'Made in USA'."  Lat.:  0 degrees, 09 minutes North;
Longitude: 144 degrees, 55 minutes East.  USS Trigger,
SS-237, in an adjoining patrol area heard the depth
charge attack lasting more than an hour, on what is
thought to have been TRITON.  TRITON was reported
overdue from patrol and presumed lost on 10 April,
1943.  In official Japanese records dated 1943, and ob
tained in 1998, the sinking of a submarine by Japanese
Subchaser #23 is indicated in one report but question
able in another.

TRITON's Last Message from LT CDR George K. MacKenzie, Jr.: 
"Two groups of smokes, 5 or more ships each, plus escorts (11 March 1943) Am chasing"

On TRITON's last War Patrol, she sank 4 ships out of a 5 ship convoy.  Admiral William F. Halsey remarked --

"....When you get five out of five, you can come home...TRITON's actions could well be emulated by other submarine personnel."
