In November 1942 the division, under the command of Lieutenant General Heisuke Abe, was scheduled to be deployed to Guadalcanal. However, after attempts to reinforce the Japanese garrison on the island failed, the decision was made to divert the "41st Division", along with the 20th Division, which was being shipped from Korea at the same time, and land them on New Guinea. Consequently, the 41st Division arrived at Wewak on 12 February 1943, where they were attached to the 18th Army and subsequently took part in the New Guinea campaign throughout 1943–45, fighting against Australian and United States forces. At this time, the Shoge Detachment was sent to fortify positions at Lae, eventually participating in Salamaua–Lae campaign together with 51st Division. By 10 July 1944, the 18th Army was reduced to essentially just the "41st Division", fighting a failed offensive during the Battle of Driniumor River in July 1944 and suffering heavy casualties in the process. The remnants of the "41st Division" have retreated to Prince Alexander Mountains and has a heavy loss of life due malnutrition and disease before the war ended with surrender of Japan 15 August 1945.
