 On 17 November , fighting for the main position around Sattelberg commenced . The previous night , in order to prepare for the attack on the 2200 feature , the 2 / 48th Battalion captured Green Ridge , a small but important feature that dominated the Sattelberg road . The capture of the ridge secured a start line forward of Jivevaneng for Whitehead 's 26th Brigade to launch the first stage of their attack upon Sattelberg . The following day , the 2 / 48th Battalion handed over responsibility for the defence of the ridge to a company from the 2 / 23rd Battalion , and the attack commenced amidst heavy supporting artillery and machine @-@ gun fire . In response , the Japanese artillery from Sattelberg fired a limited barrage onto the Australians on Green Ridge .
