 A company from the 2 / 28th Battalion captured Victoria shortly after coming ashore , and the battalion first met opposition at Flagstaff Hill at 10 : 45 am . One of the battalion 's companies subsequently captured the hill , while its other companies continued to advance . The 2 / 28th Battalion encountered increasing opposition as the day progressed , particularly to the west of its area of responsibility . During the afternoon of 10 June the battalion engaged Japanese troops in the area west of Flagstaff Hill ( at the junction of Callaghan and MacArthur Roads ) , with the infantrymen being supported by tanks and mortars ; the Australians counted 18 Japanese dead by the end of the day , and suffered several fatalities and men wounded in this fighting . After civilians reported that no Japanese were stationed on the Hamilton peninsula which formed the western side of Victoria Harbour , a troop from the 2 / 11th Commando Squadron was landed in the area during 10 June and secured it without opposition .
