Under cover of a most intense mortar barrage the enemy counter-attacked, and 2nd Lieutenant Ngarimu ordered his men to stand to and engage the enemy man or man. This they did with such good effect that the attackers were virtually mown down, 2nd Lieutenant Ngarimu personally killing several. He was twice wounded, once by rifle fire in the shoulder and later by shrapnel in the leg, and though urged by both his company and battalion commanders to go out, he refused to do so, saying that he would stay a little while with his men. He stayed until he met his death the following morning.
In his last year he spent two hundred and fifty-four days at sea, submerged for nearly half the time, and his ship was hunted thirteen times and had two hundred and fifty depth-charges aimed at her. His many and brilliant successes were due to his constant activity and skill, and the daring which never failed him when there was an enemy to be attacked.
