The Battle for Mubo was part of the Australian advance on Salamaua which would ultimately destroy the major Japanese base at Lae. Attempting delay such an advance, the Japanese established a defensive position at the tactically important area of Mubo.
As part of a Japanese counter-attack on the advancing Australian 17th Brigade, an isolated company under the command of CAPT Leslie Tatterson, was attacked by the 102nd and 115th Regiments of the Imperial Japanese Army. Between the 9th and 11th May 1943, the company held out inflicting over 100 casualties on the IJA and suffering 12 of its own. The delay caused by this stubborn defence would enable the Allies to consolidate so that Mubo fell to the Allies on 12th July 1943.
