25 October 1944:
Battle off Cape Engano in the Battle of Leyte Gulf: Air attack by planes from U.S. TF 38. At 0835 a line of three near-miss bombs or - more likely, torpedo hits - exploded against the hull on the port side forward abreast the No.1 elevator. Massive hull rupture resulted, and Boiler rooms No.2 and No.4 on the port side immediately flooded, and the carrier heeled quickly to a dangerous 27 degree list. But damage control was swift, and after the attack, the list was corrected to 15 degrees and CHITOSE remained underway. However the rudder had failed and it was necessary to steer the carrier by using the after engines. At 0855 the list to port increased again to 20 degrees, the forward starboard engine room flooded, and speed down to 14 knots. At 0915 the after starboard engine failed, and speed dropped still further. The carrier struggled on, but at 0925 the port after engine room flooded and she went dead in the water. Though the list was 30 degrees, RAdm Matsuda on HYUGA ordered ISUZU to close and attempt to take her in tow. This proved impossible.
Sunk: At 0937 CHITOSE lay right over on her port side and nosed under with the loss of Captain Kishi Yoshiyuki and 903 officers and men. The ISUZU rescued 35 officers and 445 men and SHIMOTSUKI rescued 121 officers and men.(Position 19 - 20' N, 126 - 20' E.)

20 December 1944:
Removed from the Navy list.
