April 6, 1929 in Nagasaki.
In a stormy sea, 1936
Under attack at Rabaul raid on November 2, 1943
In May 1945, Haguro became the target of the British "Operation Dukedom" and was ambushed. The 26th Destroyer Flotilla found her with the destroyer Kamikaze just after midnight on 16 May 1945, and began the attack. During the battle, Kamikaze was lightly damaged, but Haguro was hit by gunfire and three Mark IX torpedoes from the British destroyers. She soon began to slow down and took a 30-degree list to port.
At 02:32, Haguro began to go down stern first in the Malacca Strait, 55 mi (48 nmi; 89 km) off Penang; Kamikaze rescued 320 survivors, but 900 men, including Vice Admiral Hashimoto and Rear Admiral Sugiura, perished with her. Rear Admiral Sugiura was posthumously promoted to vice admiral on 16 May. Haguro was the last major Japanese warship to be sunk in a surface action during the war.
