While Lawrence is discussing the transfer requests with Vincent, a torpedo hits the ship but does not detonate. Lawrence volunteers to disarm the torpedo, which has lodged in the sick bay next to Creighton's bed, and with Flannigan's help, succeeds. Soon after, Lawrence receives orders to blow up a Japanese submarine pen, and tells the men that although it will be their last mission together, he is proud to have served with them. Although Flannigan voices disdain that Lawrence will again dodge dangerous duty, Lawrence leads the mission, which is discovered when one of the men accidentally trips a signal wire. Japanese sentries shoot at the men as they plant the charges, and Lawrence is stabbed in hand-to-hand combat with a Japanese diver. He orders Flannigan to leave him behind, but Flannigan tows him to safety. The mission is a success, and soon Lawrence is recuperating beside Creighton. Finally won over by Lawrence's bravery, the men show their acceptance of him by asking him to sign the portrait they have drawn of Cassidy to present to his widow.
