, the US warships opened fire and sank one of the Japanese destroyers. Tanaka and the rest of his ships, however, reacted quickly and launched numerous torpedoes at the US warships. The Japanese torpedoes hit and sank one US cruiser and heavily damaged three others, enabling the rest of Tanaka's force to escape without significant additional damage but also without completing the mission of delivering the food supplies. Although a severe tactical defeat for the US, the battle had little strategic impact as the Japanese were unable to take advantage of the victory to assist their ultimately unsuccessful efforts to drive Allied forces from Guadalcanal.

s stationed at Tulagi, and a cycle of bright moonlight, the Japanese had switched to using submarines to deliver provisions to their forces on Guadalcanal. Beginning on November 16, 1942, and continuing for the next three weeks, 16 submarines made nocturnal deliveries of foodstuffs to the island, with one submarine making the trip each night. Each submarine could deliver 20 to 30 tons of supplies, about one day's worth of food, for the 17th Army, but the difficult task of transporting the supplies by hand through the jungle to the frontline units limited their value to sustain the Japanese troops on Guadalcanal. At the same time, the Japanese tried to establish a chain of three bases in the central Solomons to allow small boats to use them as staging sites for making supply deliveries to Guadalcanal, but damaging Allied airstrikes on the bases forced the abandonment of this plan.

On November 26, the 17th Army notified Imamura that it faced a critical food crisis. Some front-line units had not been resupplied for six days and even the rear-area troops were on one-third rations. The situation forced the Japanese to return to using destroyers to deliver the necessary supplies.

Eighth Fleet personnel devised a plan to help reduce the exposure of destroyers delivering supplies to Guadalcanal. Large oil or gas drums were cleaned and filled with medical supplies and food, with enough air space to provide buoyancy, and strung together with rope. When the destroyers arrived at Guadalcanal they would make a sharp turn, the drums would be cut loose, and a swimmer or boat from shore could pick up the buoyed end of a rope and return it to the beach, where the soldiers could haul in the supplies.

Upon taking command, Wright briefed his ship commanders on his plan for engaging the Japanese in future, expected night battles around Guadalcanal. The plan, which he had drafted with Kinkaid, stated that radar-equipped destroyers were to scout in front of the cruisers and deliver a surprise torpedo attack upon sighting Japanese warships, then vacate the area to give the cruisers a clear field of fire. The cruisers were then to engage with gunfire from 10000 yards (9,144 m) to 12000 yards (10,972.8 m). The cruisers' floatplane

s would scout and drop flares during the battle.

On November 29, Allied intelligence personnel intercepted and decoded a Japanese message transmitted to the 17th Army on Guadalcanal alerting them to Tanaka's supply run. Informed of the message, Halsey ordered Wright to take TF67 to intercept Tanaka off Guadalcanal. TF67, with Wright flying his flag on Minneapolis, departed Espiritu Santo at 27 kn (32.9 mph; 52.9 km/h) just before midnight on November 29 for the 580 miles (933.4 km) run to Guadalcanal.

, returning from a convoy escort assignment to Guadalcanal, were ordered to join up with TF67. Lacking the time to brief the commanding officers of the joining destroyers of his battle plan, Wright assigned them a position behind the cruisers. At 17:00 on November 30, Wright's cruisers launched one floatplane each for Tulagi to drop flares during the expected battle that night. At 20:00, Wright sent his crews to battle stations.

Tanaka's force departed the Shortlands just after midnight on November 30 for the run to Guadalcanal.

 stationed in southern Bougainville, reported by radio the departure of Tanaka's ships from Shortland and this message was passed to Wright. At the same time, a Japanese search aircraft spotted an Allied convoy near Guadalcanal and communicated the sighting to Tanaka who told his destroyer commanders to expect action that night and that, "In such an event, utmost efforts will be made to destroy the enemy without regard for the unloading of supplies."

 from Indispensable Strait. The Japanese ships were in line ahead formation, interval 600 metres (656.2 yd), in the order of Takanami, Oyashio, Kuroshio, Kagero, Makinami, Naganami, Kawakaze, and Suzukaze. At this same time, TF67 entered Lengo Channel en route to Ironbottom Sound. Wright's ships were in column in the order Fletcher, Perkins, Maury, Drayton, Minneapolis, New Orleans, Pensacola, Honolulu, Northampton, Lamson, and Lardner. The four van destroyers led the cruisers by 4000 yards (3,657.6 m) and the cruisers steamed 1000 yards (914.4 m) apart.

At 22:40, Tanaka's ships passed south of Savo about 3 miles (5 km) offshore from Guadalcanal and slowed to 12 kn (14.6 mph; 23.5 km/h) as they approached the unloading area. Takanami took station about 1 miles (2 km) seaward to screen the column. At the same time, TF67 exited Lengo Channel into the sound and headed at 20 kn (24.4 mph; 39.2 km/h) towards Savo Island. Wright's van destroyers moved to a position slightly inshore of the cruisers. The night sky was moonless with between 2 miles (3 km) and 7 miles (11 km) of visibility. Because of extremely calm seas which created a suction effect on their pontoons, Wright's cruiser floatplanes were delayed in lifting off from Tulagi harbor, and would not be a factor in the battle.

At 23:06, Wright's force began to detect Tanaka's ships on radar near Cape Esperance on Guadalcanal about 23000 yards (21,031.2 m) away. Wright's destroyers rejoined the column as it continued to head towards Savo. At the same time, Tanaka's ships, which were not equipped with radar, split into two groups and prepared to shove the drums overboard. Naganami, Kawakaze, and Suzukaze headed for their drop-off point near Doma Reef while Makinami, Kagero, Oyashio, and Kurashio aimed for nearby Tassafaronga. At 23:12, Takanami's crew visually sighted Wright's column, quickly confirmed by lookouts on Tanaka's other ships. At 23:16, Tanaka ordered unloading preparations halted and "All ships attack."

Action

At 23:14, operators on Fletcher established firm radar contact with Takanami and the lead group of four drum-carrying destroyers. At 23:15, with the range 7000 yards (6,400.8 m), Commander William M. Cole, commander of Wright's destroyer group and captain of Fletcher, radioed Wright for permission to fire torpedoes. Wright waited two minutes and then responded with, "Range on bogies [Tanaka's ships on radar] excessive at present." Cole responded that the range was fine. Another two minutes passed before Wright responded with permission to fire. In the meantime, the US destroyer's targets escaped from an optimum firing setup ahead to a marginal position passing abeam, giving the American torpedoes a long overtaking run near the limit of their range. At 23:20, Fletcher, Perkins, and Drayton fired a total of 20 Mark 15 torpedo

es towards Tanaka's ships. Maury, lacking SG radar and thus having no contacts, withheld fire.

At the same time, Wright ordered his force to open fire. At 23:21, Minneapolis complied with her first salvo, quickly followed by the other American cruisers. Cole's four destroyers fired star shells to illuminate the targets as previously directed then increased speed to clear the area for the cruisers to operate.

Because of her closer proximity to Wright's column, Takanami was the target of most of the American's initial gunfire. Takanami returned fire and launched her full load of eight torpedoes, but was quickly hit by American gunfire and, within four minutes, was set afire and incapacitated. As Takanami was destroyed, the rest of Tanaka's ships, almost unnoticed by the Americans, were increasing speed, maneuvering, and preparing to respond to the American attack. All of the American torpedoes missed. Historian Russell S. Crenshaw, Jr. postulates that had the twenty-four torpedoes fired by U.S. Navy destroyers during the battle not been fatally flawed, the outcome of the battle might have been different.

Tanaka's flagship, Naganami, reversed course to starboard, opened fire and began laying a smoke screen. The next two ships astern, Kawakaze and Suzukaze, reversed course to port. At 23:23, Suzukaze fired eight torpedoes in the direction of the gunflashes from Wright's cruisers, followed by Naganami and Kawakaze which fired their full loads of eight torpedoes at 23:32 and 23:33 respectively.

Meanwhile, the four destroyers at the head of the Japanese column maintained their heading down the Guadalcanal coast, allowing Wright's cruisers to pass on the opposite course. Once clear of Takanami at 23:28, Kuroshio fired four and Oyashio fired eight torpedoes in the direction of Wright's column and then reversed course and increased speed. Wright's cruisers maintained the same course and speed as the 44 Japanese torpedoes headed in their direction.

At 23:27, as Minneapolis fired her ninth salvo and Wright prepared to order a course change for his column, two torpedoes, from either Suzukaze or Takanami, slammed into her forward half. One warhead exploded the aviation fuel storage tanks forward of turret one and the other knocked out three of the ship's four firerooms. The bow forward of turret one folded down at a 70-degree angle and the ship lost power and steering control. Thirty-seven men were killed.

Less than a minute later a torpedo hit New Orleans abreast of turret one and exploded the ship's forward ammunition magazines and aviation gasoline storage. The blast severed the ship's entire bow forward of turret two. The bow twisted to port, damaging the ship's hull as it was wrenched free by the ship's momentum, and sank immediately off the aft port quarter. Everyone in turrets one and two perished. New Orleans was forced into a reverse course to starboard and lost steering and communications. A total of 183 men were killed. Herbert Brown, a seaman in the ship's plotting room, described the scene after the torpedo hit,

Pensacola followed next astern in the cruiser column. Observing Minneapolis and New Orleans taking hits and slowing, Pensacola steered to pass them on the port side and then, once past, returned to the same base course. At 23:39, Pensacola took a torpedo abreast the mainmast. The explosion spread flaming oil throughout the interior and across the main deck of the ship, killing 125 of the ship's crew. The hit ripped away the port outer driveshaft and the ship took a 13-degree list and lost power, communications, and steering.

Astern of Pensacola, Honolulu's captain chose to pass Minneapolis and New Orleans on the starboard side. At the same time, the ship increased speed to 30 kn (36.5 mph; 58.8 km/h), maneuvered radically, and successfully transited the battle area without taking any damage while maintaining main battery fire at the rapidly disappearing Japanese destroyers.

The last cruiser in the American column, Northampton, followed Honolulu to pass the damaged cruisers ahead to starboard. Unlike Honolulu, Northampton did not increase speed or attempt any radical maneuvers. At 23:48, after returning to the base course, Northampton was hit by two of Kawakaze's torpedoes. One hit 10 feet (3 m) below the waterline abreast the after engine room, and four seconds later, the second hit 40 feet (12 m) further aft. The after engine room flooded, three of four shafts ceased turning, and the ship listed 10 degrees to port and caught fire. Fifty men were killed.

The last ships in Wright's column, Lamson and Lardner, failed to locate any targets and exited the battle area to the east after being mistakenly fired on by machine guns from New Orleans. Cole's four destroyers circled completely around Savo Island at maximum speed and reentered the battle area, but the engagement had already ended.

Meanwhile, at 23:44 Tanaka ordered his ships to break contact and retire from the battle area. As they proceeded up Guadalcanal's coast, Kuroshio and Kagero fired eight more torpedoes towards the American ships, which all missed. When Takanami failed to respond to radio calls, Tanaka directed Oyashio and Kuroshio to go to her assistance. The two destroyers located the burning ship at 01:00 on December 1 but abandoned rescue efforts after detecting American warships in the area. Oyashio and Kuroshio quickly departed the sound to rejoin the rest of Tanaka's ships for the return journey to the Shortlands, which they reached 10 hours later. Takanami was the only Japanese warship hit by American gunfire and seriously damaged during the battle.

Aftermath

Takanami’s surviving crew abandoned ship at 01:30, but a large explosion killed many more of them in the water, including the destroyer division commander, Toshio Shimizu, and the ship's captain, Masami Ogura. Of her crew of 244, 48 survived to reach shore on Guadalcanal and 19 of them were captured by the Americans.

Northampton’s crew was unable to contain the ship's fires and list and began to abandon ship at 01:30. The ship sank at 03:04 about 4 miles (6 km) from Doma Cove on Guadalcanal (09°12′S 159°50′E). Fletcher and Drayton rescued the ship's 773 survivors.

Minneapolis, New Orleans, and Pensacola were able to make it the 19 miles (30.6 km) to Tulagi on the morning of December 1 where they were berthed for emergency repairs. The fires on Pensacola burned for 12 hours before being extinguished. Pensacola departed Tulagi for rear area ports and further repair on December 6. After construction of temporary bows from coconut logs, Minneapolis and New Orleans departed Tulagi for Espiritu Santo or Sydney

, Australia on December 12. All three cruisers required lengthy and extensive repairs. New Orleans returned to action in August, Minneapolis in September, and Pensacola in October 1943.

, one of the highest American military decorations for bravery, for his actions during the engagement. Mitigating to some degree the destruction of his task force, Wright, in his after-action report, claimed that his force sank four Japanese destroyers and damaged two others. Halsey, in his comments on Wright's report, placed much of the blame for the defeat on Cole, saying that the destroyer squadron commander fired his torpedoes from too great a distance to be effective and should have "helped" the cruisers instead of circling around Savo Island. Tanaka claimed to have sunk a battleship and two cruisers in the battle.

The results of the battle led to further discussion in the US Pacific Fleet about changes in tactical doctrine and the need for technical improvements, such as flashless powder. It was not until eight months later that the naval high command recognized there was serious problems with the functioning of the torpedoes. The Americans were still unaware of the range and power of Japanese torpedoes and the effectiveness of Japanese night battle tactics. In fact, Wright claimed that his ships must have been fired on by submarines since the observed position of Tanaka's ships "make it improbable that torpedoes with speed-distance characteristics similar to our own" could have caused such damage, though Tanaka states that his torpedoes were fired at a range as short as three miles. The Americans would not recognize the true capabilities of their Pacific adversary's torpedoes and night tactics until well into 1943. After the war, Tanaka said of his victory at Tassafaronga, "I have heard that US naval experts praised my command in that action. I am not deserving of such honors. It was the superb proficiency and devotion of the men who served me that produced the tactical victory for us."

In spite of their defeat in the battle, the Americans had prevented Tanaka from landing the desperately needed food supplies on Guadalcanal, albeit at high cost. A second Japanese supply delivery attempt by 10 destroyers led by Tanaka on December 3 successfully dumped 1,500 drums of provisions off Tassafaronga, but strafing American aircraft sank all but 310 of them the next day before they could be pulled ashore. On December 7, a third attempt by 12 destroyers was turned back by US PT boats off Cape Esperance. The next night, two US PT boats torpedoed and sank the Japanese submarine I-3 as it attempted to deliver supplies to Guadalcanal. Based on the difficulties experienced trying to deliver food to the island, the Japanese Navy informed Imamura on December 8 that they intended to stop all destroyer transportation runs to Guadalcanal immediately. After Imamura protested, the navy agreed to one more run to the island.

The last attempt to deliver food to Guadalcanal by destroyers in 1942 was led by Tanaka on the night of December 11 and consisted of 11 destroyers. Five US PT boats met Tanaka off Guadalcanal and torpedoed his flagship Teruzuki

, severely damaging the destroyer and injuring Tanaka. After Tanaka transferred to Naganami, Teruzuki was scuttled. Only 220 of the 1,200 drums released that night were recovered by Japanese army personnel on shore. Tanaka was subsequently relieved of command and transferred to Japan on December 29, 1942.
