Sakito Maru

Sakito Maru was built in 1939 by the Mitsubishi Zosen Kaisha in Nagasaki for the Nippon Yusen shipping company.[1]

After the beginning of World War II, Sakito Maru was converted into a heavily armed merchant cruiser.[2] She and the merchant cruiser Asaka Maru were operating as transports, carrying reinforcements to the Japanese garrison of Attu in the Aleutian Islands during the Aleutian Islands campaign,[2] when their convoy encountered the warships of United States Navy Task Group 16.6[3] in the North Pacific Ocean near the Komandorski Islands on 27 March 1943.[2] Sakito Maru and Asaka Maru steamed away[4] and avoided combat in the ensuing Battle of the Komandorski Islands.[5] Two U.S. Navy PBY Catalina flying boats sighted the two transports during the afternoon,[6] but land-based United States Army Air Forces airstrikes launched against them during the afternoon failed to find them.[6] They returned safely to Paramushiro in the Kuril Islands, but failed to deliver the reinforcements to Attu.[6]

On 29 February 1944, Sakito Maru was carrying the Imperial Japanese Army′s 18th Infantry Regiment as part of Convoy Matsu-01, which was transporting the 29th Division of the Kwantung Army from Manchukuo to Guam. Matsu No. 1 consisted of four large transports escorted by three Yūgumo-class destroyers of Destroyer Division 31, namely Asashimo, Kishinami, and Okinami. The American submarine USS Trout (SS-202) attacked the convoy about 625 nautical miles (1,158 km; 719 mi) east of Formosa.[7] The submarine badly damaged the large passenger-cargo ship Aki Maru. Two torpedoes also hit Sakito Maru around 17:56 and she caught fire.[8]

Asashimo detected Trout and dropped 19 depth charges. Oil and debris came to the surface and the destroyer dropped a final depth charge on that spot, sinking the American submarine with the loss of all hands at the position 22°40′N 131°45′E.[9] At 04:00 on 1 March 1944, the burning Sakito Maru also sank. Of the 3,500 men on board, 2,358 soldiers, 65 ship's gunners, and 52 crewmen died. Also lost were several light tanks and most of the regiment's equipment.[8]
