The hill was also used as a defensive point to protect their positions around the upper Matanikau valley as well as to protect the Maruyama Road, which was a trail used by the Japanese to move men and supplies into the interior of the island.
Bjerget blev også brugt som en defensiv stilling til at beskytte deres stilling ved den øvre del af Matanikaudalen og beskytte Maruyamavejen, som var en sti japanerne brugte til at fremføre mænd og forsyninger til øens indre.
