Admiral (later Fleet Admiral) William F. Halsey's Third Fleet of 738 ships including 18 aircraft carriers, six battleships, 17 cruisers, 64 destroyers and over 600 support ships land the Army's X Corps (24th Infantry and 1st Cavalry Divisions) and the XXIV Corps (7th, 77th and 96th Infantry Divisions) that begins the campaign to retake Leyte.

24 October 1944:
The I-45 is redirected to take up station E of Leyte.

25 October 1944:
I-45 is one of the submarines that the Japanese think may have hit the USS SANTEE.

27 October 1944:
40 miles E of Leyte. LtCdr G. E. Marix's USS EVERSOLE (DE-404), RICHARD S. BULL (DE-402) and Lt J. C. Horton's USS WHITEHURST (DE-634) of Task Unit 77.7.1 are escorting a convoy from Leyte Gulf.

28 October 1944:
Off Dinagat Island, Philippines. At 0230, the EVERSOLE makes sonar contact with a submarine, but is immediately hit by the first of two torpedoes. LtCdr Marix orders Abandon Ship. The EVERSOLE remains afloat for about 15 minutes before sinking stern first at 10-18N, 127-37E.

About 0300, the I-45 surfaces, opens fire on the survivors with its machine gun, then dives. Five minutes later, an underwater explosion (probably one of the EVERSOLE's own depth charges) kills or wounds many of the men in the water. The BULL requests an ASW screen while she rescues 136 wounded survivors.

The WHITEHURST detaches from the convoy to conduct a search. She arrives several hours later and at 0545 picks up a contact. Lt Horton conducts three unsuccessful attacks with barrages of 7.2-inch Mark 10 "hedgehog" projector charges, but his fourth attack results in several underwater explosions that are so heavy they damage the WHITEHURST's sound gear. The BULL continues the search but finds nothing. The lookouts in both ships notice many pieces of wood and other debris in a widening oil slick. The submarine sunk in these attacks E of Siargao Island at 10-10N, 127-28E is probably the I-45.

21 November 1944:
The I-45 is presumed lost with all 104 hands off Philippines.

10 March 1945:
Removed from the Navy List.
