Yoshino Maru

Yoshino Maru (Kanji:) was an 8,950-ton Japanese troop transport during World War II, which sank on 31 July 1944 with great loss of life.
"Yoshino Maru" was built in 1907 as "Kleist" for the Norddeutscher Lloyd by the Schichau-Werke in Danzig, Germany.
In 1919, she was ceded to the United Kingdom as war reparation, who sold her in 1921 to the Japanese government, where she was renamed "Yoshino Maru". In 1929, she was sold to Kinkai Yusen and used as an ocean liner. 
At the start of the Second Sino-Japanese War, she was requisitioned as a transport ship by the Imperial Japanese Navy.
On 31 July 1944, she was travelling in Convoy MI-11 from Moji, Japan, to Miri, Borneo, with 5,063 soldiers on board, when the convoy was attacked by a United States Navy submarine wolfpack. At 3:40 AM, torpedoed and sank "Yoshino Maru" with four torpedoes; losses aboard ship included 2,442 soldiers, as well as 18 gunners, 35 crewmen, and 400 cubic meters (14,120 cubic feet) of ammunition.
