Rear Admiral Yamamoto, perhaps growing impatient, decides that his task force needs to penetrate deeper into enemy waters. As soon as night falls his force is headed further south. It is risky move, based on nothing but a hunch, but so is sitting for days on the edge of the enemy’s detection radius.
It is a dark night. The waning moon is in its last quarter and is at times obscured by the partial cloud cover. The sea is fairly calm. At 0120 hours Japanese radar detects a large force of ships coming straight at them from the west.
Yamamoto does not hesitate. He turns his own ships to meet the unknown enemy. The Japanese form up in three parallel columns. On each flank is a light cruiser, a heavy cruiser, and four destroyers while the center column has one light cruiser, two heavy cruisers, and six destroyers. The two forces are just over thirty kilometers apart and now begin to close at forty knots. It will not be long before contact is made.

Captain Ishii is on the bridge less than a minute after combat stations are ordered.
“What do we have, Exec?” he asks Lieutenant Miharu.
“Enemy ships closing with us from the west, sir,” responds Miharu. “It looks like a large force, composition unknown. We have been ordered to close with them.” Ishii turns to Lieutenant Kuwaki.
“I’ll take the conn,” he says.
“The conn is yours, sir,” Kuwaki responds.
For the next fifteen minutes there is quiet on the bridge except for murmured reports that various stations are manned and ready. Ishii leans forward and speaks into a voice tube.
“What do you see, radar?” Petty Officer Takahashi’s voice comes back up the tube.
“It looks like the enemy is in two columns, sir,” comes the reply. “Large ships, I estimate their speed at fifteen knots. Between ten and twenty ships, I think.”
Ishii glances across the darkened bridge at Lieutenant Miharu. “That’s too fast for freighters or troop transports,” he comments.*
“It could be almost anything,” says the lieutenant. After that they wait as the distance closes; the enemy does not alter course or speed. Finally, at 14,000 meters, Yamamoto orders his cruisers to open fire. Star shells burst over the enemy force as the cruiser’s 8” turrets roar and fling their first volley at the oncoming ships.

Fortune has placed the Japanese in front of a worthy prize; fourteen unescorted tankers, eastbound from Tinian. Yamamoto would perhaps have preferred to catch them westbound and full of fuel, but he is not inclined to complain. In fact it is some time before the lack of return fire finally convinces him there are no enemy warships present. By this time two of the tankers have been hit and the rest are scattering in every direction in lumbering, ungainly flight.
Yamamoto releases the ships in his two flank columns to operate independently while his main column continues ahead.
Hibiki, the second ship in the starboard column, races into the night looking for a target.

“Range 4000 meters,” comes the report as
Hibiki’s searchlight probes across the water and illuminates a fleeing ship.
“Helm, change course twenty degrees starboard,” says Ishii. “Lieutenant Kuwaki, open fire. Lieutenant Sugiyura, are you ready to launch torpedoes?”
“Yes sir!” replies Sugiyura. “If I can’t hit a target like that I’ll eat my stripes.” Ishii grins.
“Launch torpedoes,” he says. The destroyer’s four 5” guns are already finding the range a moment later when the ship rocks as a spread of torpedoes leap from their tubes and churn towards the tanker.
Their target, though no one aboard
Hibiki knows it, is the somewhat awkwardly named
Agwiworld. Launched in 1920, the 6771 ton tanker has operated in the Pacific since the start of the war. Now, however, she is about to become Hibiki’s latest and largest victim.
Two torpedoes strike the tanker on her starboard side, one amidships and one about forty feet behind the bow. The force of the explosions lifts the bow so high that the stern is nearly left awash. Flames are already erupting as she ship settles back, stricken.
This is not a target
Hibiki’s gunners can miss. Shell after shell rips into the tanker, which is soon ablaze from one end to the other. Destroyer
Akigumo comes up and adds her firepower to the attack but it is hardly needed. The tanker is obviously doomed.
Burning and sinking tankers dot the ocean. In the chaos perhaps half the tankers have slipped away. Yamamoto is not concerned; the enemy ships can’t get far and when the sun rises
Ikoma’s air groups can hunt down the survivors. He collects his ships. It takes some time to resume formation in the darkness and it is approaching dawn before the Japanese task force turns back to the north. Behind them they leave sinking ships, an ocean fouled with patches of burning oil and other debris, and lifeboats filled with shocked survivors.

*In this Ishii is mistaken; he does not know that the newer American merchant ships, such as the Victory ships, are capable of cruising at 15 knots.
