The main redoubt viewed from the north-east. Wanganui and Ngāti Kahungūnu kūpapa attacked from the left up the slope, while Te Arawa and the Armed Constabulary attacked from the right over fairly level ground. The flanking angles at opposite corners do not offer a good defensive field of fire along the eastern (left) or western faces of the parapet. Loopholes had been made through the parapet but they were too restricted in the field of fire offered. Once up under the cover of the breastworks, the attacking forces were able to undermine them and gain entry to the interior.
