Wartime History
In late 1942 occupied by the Japanese Army and used as a logistic base in support of their drive inland towards Wau. During early February 1943, after the Japanese failure to capture Wau, their surviving force retreated to Mubo and dug in to defend the Mubo and Green Hill area to block the advance of the Australian Army.

During April 22 to May 29, 1943 the Australian  Army 2/7th Infantry Battalion attacked the Mubo area, at features dubbed "The Pimple" and "Green Hill". This attack was a diversion that allowed the 2/3rd Independent Company to advance in an arc to raid Bobdubi.

During July 7-13, 1943 attacked by the Australian Army 17th Brigade's 58th Battalion and 59th Battalion. By July 13, 1943 resistance ceased and the Australians occupied the area and advanced northward.
