 Although in places there was a mixture of different companies and platoons dug in together , the Australians were deployed with the 8th Battalion in the south still centred on Bolton 's Ridge . North of them , covering the southern sector of 400 Plateau , were the mixed together 6th and 7th Battalions , both now commanded by Colonel Walter <unk> of the 6th . North of them was the 5th Battalion , and the 10th Battalion covered the northern sector of 400 Plateau at Johnston 's Jolly . But by now they were battalions in name only , having all taken heavy casualties ; the commanders had little accurate knowledge of where their men were located .
