The Jap concluded to run for it and started in to work his wireless, also swung his ship into such a position as to bring his gun for submarine defence, 4.7 quick firer, into action. Meantime the _Wolf_ had opened fire on her in deadly earnest. One six-inch shell from the after gun struck the _Hitachi_ and exploded just under her gun where the gun crew was working, killing six Japs and blowing the balance into the water. I saw one Jap in particular hoisted high into the air above the smoke of the explosion, and he was spinning around like a pin-wheel. Another shot from the after gun put the gun on the _Hitachi_ out of commission altogether, and killed another man. In the meantime from forward the _Wolf_ had succeeded in putting a 4.5 shell through the wireless room, where the operator was working. This shell came through one side of the room, passed between the operator and his "set," cutting one of his aerial leads in two, and passed out through the opposite side of the room, decapitating a man standing outside. This shell eventually hit a ventilator shaft, ripped it to pieces and knocked a man down in the engine room so hard that he afterwards died of internal injuries. There were several more hits, one on the water line in No. 4 hatch, two more in the stern, and one in the wheelhouse on the bridge. About this time the flying machine came along and tried to drop a bomb on deck forward but missed, the bomb exploding when it hit the water just ahead. The cannonading, while it lasted, was very severe, there being something over forty shots fired in as short a time as possible. Of these shots only nine were direct hits. I must add that the first possible twenty of these shots were directed in such a manner as to hit (if they did) the vessel in such a position as not to sink or permanently disable her; but towards the last, when it became evident that the Jap was trying to make her getaway, the shooting was in deadly earnest. Several broadsides were fired, which I think did more damage to the _Wolf_ than to the _Hitachi Maru_, as the air concussion stove in the doors and glass ports on all the staterooms on the berth deck. In several of the rooms the wash basins and plumbing were broken. I was standing in my open doorway with one foot on the threshold in such a manner that half of my foot protruded outside the line of the wall. When the first broadside was fired the concussion or rush of air passing my doorway, hit the part of my foot outside the door, feeling just exactly as if somebody had kicked it away or hit it with a baseball bat. Something went wrong with the six-inch gun mounted on the stern of the _Wolf_ and a shell exploded a few yards away from the muzzle, putting the gun crew and gun out of commission for the balance of the voyage.
