on 25 or 26 June 1942, according to different sources, and began repairs there. I-168′s 6 June report of having sunk Yorktown was premature, but Yorktown eventually rolled over and sank in of water on the morning of 7 June 1942. One of only two Japanese submarines to make contact with enemy forces during the Battle of Midway and the only one to inflict damage, I-168 sank the only two ships the U.S. Navy lost during the battle, and at the time Yorktown was the largest ship sunk by a submarine during the Pacific campaign of World War II. Guadalcanal campaign During I-168′s stay at Sasebo, the Guadalcanal campaign began on 7 August 1942 with United States Marine Corps landings on Guadalcanal in the southeastern Solomon Islands. With her repairs complete, I-168 departed Sasebo on 31 August 1942 and proceeded to the Japanese base at Truk Atoll in the Caroline Islands to support Japanese forces in the campaign. Sources do not describe her activities over the next two months, but she arrived at Kure, Japan, on 18 November 1942 and was drydocked there for repairs. After completion of her repairs, I-168 got underway from Kure on 15 December 1942 and made for Truk, which she reached on 22 December 1942. She then moved to the Japanese anchorage in the Shortland Islands, from which she departed carrying 15 tons of cargo for Japanese forces on Guadalcanal. She arrived at Guadalcanal on 1 January 1943 and unloaded 60 percent of her cargo before two Allied patrol boats forced her to withdraw and head back to the Shortlands. She made an overnight stop at the Shortlands anchorage on 3–4 January 1943, called at Truk from 7 to 8 January, and then proceeded to Kure, Japan, where she arrived on 14 January 1943 to undergo repairs. Aleutian Islands campaign While I-168 was at Kure, she was assigned to the Northern District Force to support Japanese forces on Attu and Kiska in the Aleutian Islands during the Aleutian Islands campaign. She got underway from Kure on 22 February 1943, called at Yokosuka from 25 February to 5 March 1943, and then proceeded to Paramushiro in the northern Kuril Islands, which she reached on 10 March 1943. On 13 March 1943, I-168 departed Paramushiro on her first Aleutians supply run, carrying ammunition bound for Attu and Kiska. She arrived at Holtz Bay on the northeast coast
