on Guadalcanal (called Henderson Field by the Allies) with the object of destroying Allied aircraft and the airfield's facilities. Shortly before midnight on 11 October, a U.S. force of four cruisers and five destroyers—under the command of Rear Admiral Norman Scott—intercepted Gotō's force as it approached Savo Island near Guadalcanal. Taking the Japanese by surprise, Scott's warships sank one of Gotō's cruisers and one of his destroyers, heavily damaged another cruiser, mortally wounded Gotō, and forced the rest of Gotō's warships to abandon the bombardment mission and retreat. During the exchange of gunfire, one of Scott's destroyers was sunk and one cruiser and another destroyer were heavily damaged. In the meantime, the Japanese supply convoy successfully completed unloading at Guadalcanal and began its return journey without being discovered by Scott's force. Later on the morning of 12 October, four Japanese destroyers from the supply convoy turned back to assist Gotō's retreating, damaged warships. Air attacks by U.S. aircraft from Henderson Field sank two of these destroyers later that day. As with the preceding naval engagements around Guadalcanal and to be expected from a battle of relatively limited size, the strategic outcome was inconclusive because neither the Japanese nor United States navies secured operational control of the waters around Guadalcanal as a result of this action and a heavy bombardment operation against Henderson Field would be conducted soon after, causing severe destruction in the three nights between 13 and 16 October. However, the Battle of Cape Esperance provided a significant morale boost to the U.S. Navy after its disastrous defeat at the Battle of Savo Island.

s—were usually able to make the round trip down " the Slot" to Guadalcanal and back in a single night, thereby minimizing their exposure to air attacks. Delivering troops in this manner, however, prevented most of the heavy equipment and supplies, such as heavy artillery, vehicles, and much food and ammunition, from being delivered. In addition, they expended destroyers, which were desperately needed for commerce defense. These high-speed runs occurred throughout the campaign and were later called the " Tokyo Express" by the Allies and "Rat Transportation" by the Japanese. Due to the heavier concentration of Japanese surface combat vessels and their well-positioned logistical base at Simpson Harbor, Rabaul, and their victory at the Battle of Savo Island in early August, the Japanese had established operational control over the waters around Guadalcanal at night. However, any Japanese ship remaining within range—about —of American aircraft at Henderson Field, during the daylight hours, was in danger of damaging air attacks. This persisted for the months of August and September, 1942. The presence of Admiral Scott's task force at Cape Esperance represented the U.S. Navy's first major attempt to wrest night time operational control of waters around Guadalcanal away from the Japanese. The first attempt by the Japanese Army to recapture Henderson Field was on 21 August, in the

Action

At 23:00, the ''San Francisco'' aircraft spotted Jojima's force off Guadalcanal and reported it to Scott. Scott, believing more Japanese ships were likely still on the way, continued his course towards the west side of Savo Island. At 23:33, Scott ordered his column to turn towards the southwest to a heading of 230°. All of Scott's ships understood the order as a column movement except Scott's own ship, ''San Francisco''. As the three lead U.S. destroyers executed the column movement, ''San Francisco'' turned simultaneously. ''Boise''—following immediately behind—followed ''San Francisco'', thereby throwing the three van destroyers out of formation. At 23:32, ''Helena''s radar showed the Japanese warships to be about away. At 23:35, ''Boise''s and ''Duncan''s radars also detected Gotō's ships. Between 23:42 and 23:44, ''Helena'' and ''Boise'' reported their contacts to Scott on ''San Francisco'' who mistakenly believed the two cruisers were actually tracking the three U.S. destroyers that were thrown out of formation during the column turn. Scott radioed ''Farenholt'' to ask if the destroyer was attempting to resume its station at the front of the column. ''Farenholt'' replied, "Affirmative, coming up on your starboard side," further confirming Scott's belief that the radar contacts were his own destroyers. At 23:45, ''Farenholt'' and ''Laffey''—still unaware of Gotō's approaching warships—increased speed to resume their stations at the front of the U.S. column. ''Duncan''s crew, however, thinking that ''Farenholt'' and ''Laffey'' were commencing an attack on the Japanese warships, increased speed to launch a solitary

attack on Gotō's force without telling Scott what they were doing. ''San Francisco''s radar registered the Japanese ships, but Scott was not informed of the sighting. By 23:45, Gotō's ships were only away from Scott's formation and visible to ''Helena''s and ''Salt Lake City''s lookouts. The U.S. formation at this point was in position to cross the T of the Japanese formation, giving Scott's ships a significant tactical advantage. At 23:46, still assuming that Scott was aware of the rapidly approaching Japanese warships, ''Helena'' radioed for permission to open fire, using the general procedure request, "Interrogatory Roger" (meaning, basically, "Are we clear to act?"). Scott answered with, "Roger", meaning only that the message was received, not that he was confirming the request to act. Upon receipt of Scott's "Roger", ''Helena''—thinking they now had permission—opened fire, quickly followed by ''Boise'', ''Salt Lake City'', and to Scott's further surprise, ''San Francisco''. Gotō's force was taken almost completely by surprise. At 23:43, ''Aoba''s lookouts sighted Scott's force, but Gotō assumed that they were Jojima's ships. Two minutes later, ''Aoba''s lookouts identified the ships as American, but Gotō remained skeptical and directed his ships to flash identification signals. As ''Aoba''s crew executed Gotō's order, the first American salvo smashed into ''Aoba''s superstructure. ''Aoba'' was quickly hit by up to 40 shells from ''Helena'', ''Salt Lake City'', ''San Francisco'', ''Farenholt'', and ''Laffey''. The shell hits heavily damaged ''Aoba''s communications systems and demolished two of her main gun turrets as well as her main gun director. Several large-caliber projectiles passed through ''Aoba''s flag bridge without exploding, but the force of their passage killed many men and mortally wounded Gotō. Scott—still unsure who his ships were firing at, and afraid they might be firing on his own destroyers—ordered a ceasefire at 23:47, although not every ship complied. Scott ordered ''Farenholt'' to flash her recognition signals and upon observing that ''Farenholt'' was close to his formation, he ordered the fire resumed at 23:51. ''Aoba'', continuing to receive damaging hits, turned to starboard to head away from Scott's formation and began making a smoke screen which led most of the Americans to believe that she was sinking. Scott's ships shifted their fire to ''Furutaka'', which was following behind ''Aoba''. At 23:49, ''Furutaka'' was hit in her

tubes, igniting a large fire that attracted even more shellfire from the US ships. At 23:58, a torpedo from ''Buchanan'' hit ''Furutaka'' in her forward engine room, causing severe damage. During this time, ''San Francisco'' and ''Boise'' sighted ''Fubuki'' about away and raked her with shellfire, joined soon by most of the rest of Scott's formation. Heavily damaged, ''Fubuki'' began to sink. ''Kinugasa'' and ''Hatsuyuki'' chose turning to port rather than starboard and escaped the Americans' immediate attention. During the exchange of gunfire, ''Farenholt'' received several damaging hits from both the Japanese and the American ships, killing several men. She escaped from the crossfire by crossing ahead of ''San Francisco'' and passing to the disengaged side of Scott's column. ''Duncan''—still engaged in her solitary torpedo attack on the Japanese formation—was also hit by gunfire from both sides, set afire, and looped away in her own effort to escape the crossfire. As Gotō's ships endeavored to escape, Scott's ships tightened their formation and then turned to pursue the retreating Japanese warships. At 00:06, two torpedoes from ''Kinugasa'' barely missed ''Boise''. ''Boise'' and ''Salt Lake City'' turned on their searchlights to help target the Japanese ships, giving ''Kinugasa''s gunners clear targets. At 00:10, two shells from ''Kinugasa'' exploded in ''Boise''s main ammunition magazine between turrets one and two. The resulting explosion killed almost 100 men and threatened to blow the ship apart. Seawater rushed in through rents in her hull opened by the explosion and helped quench the fire before it could explode the ship's powder magazines. ''Boise'' immediately sheered out of the column and retreated from the action. ''Kinugasa'' and ''Salt Lake City'' exchanged fire with each other, each hitting the other several times, causing minor damage to ''Kinugasa'' and damaging one of ''Salt Lake City''s boilers, reducing her speed. At 00:16, Scott ordered his ships to turn to a heading of 330° in an attempt to pursue the fleeing Japanese ships. Scott's ships, however, quickly lost sight of Gotō's ships, and all firing ceased by 00:20. The American formation was beginning to scatter, so Scott ordered a turn to 205° to disengage.


Retreat

During the battle between Scott's and Gotō's ships, Jojima's reinforcement group completed unloading at Guadalcanal and began its return journey unseen by Scott's warships, using a route that passed south of the

. Despite extensive damage, ''Aoba'' was able to join ''Kinugasa'' in retirement to the north through the Slot. ''Furutaka''s damage caused her to lose power around 00:50, and she sank at 02:28, northwest of Savo Island. ''Hatsuyuki'' picked up ''Furutaka''s survivors and joined the retreat northward. ''Boise'' extinguished her fires by 02:40 and at 03:05 rejoined Scott's formation. ''Duncan''—on fire—was abandoned by her crew at 02:00. Unaware of ''Duncan''s fate, Scott detached ''McCalla'' to search for her and retired with the rest of his ships towards Nouméa, arriving in the afternoon of 13 October. ''McCalla'' located the burning, abandoned ''Duncan'' about 03:00, and several members of ''McCalla''s crew made an attempt to keep her from sinking. By 12:00, however, they had to abandon the effort as bulkheads within ''Duncan'' collapsed causing the ship to finally sink north of Savo Island. American servicemen in boats from Guadalcanal as well as ''McCalla'' picked up ''Duncan''s scattered survivors from the sea around Savo. In total, 195 ''Duncan'' sailors survived; 48 did not. As they rescued ''Duncan''s crew, the Americans came across the more than 100 ''Fubuki'' survivors, floating in the same general area. The Japanese initially refused all rescue attempts but a day later allowed themselves to be picked up and taken prisoner. Jojima—learning of the bombardment force's crisis—detached destroyers ''Shirayuki'' and ''Murakumo'' to assist ''Furutaka'' or her survivors and ''Asagumo'' and to rendezvous with ''Kinugasa'', which had paused in her retreat northward to cover the withdrawal of Jojima's ships.

s, accompanied by 14 Grumman F4F-4 Wildcats, found the two Japanese destroyers from Guadalcanal. In the ensuing attack, ''Murakumo'' was hit by a torpedo in her engineering spaces, leaving her without power. In the meantime, ''Aoba'' and ''Hatsuyuki'' reached the sanctuary of the Japanese base in the Shortland Islands at 10:00. Rushing to assist ''Murakumo'', ''Asagumo'' and ''Natsugumo'' were attacked by another group of 11 CAF SBDs and TBFs escorted by 12 fighters at 15:45. An SBD placed its bomb almost directly amidships on ''Natsugumo'' while two more near misses contributed to her severe damage. After ''Asagumo'' took off her survivors, ''Natsugumo'' sank at 16:27. The CAF aircraft also scored several more hits on the stationary ''Murakumo'', setting her afire. After her crew abandoned ship, ''Shirayuki'' scuttled her with a torpedo, picked up her survivors, and joined the rest of the Japanese warships for the remainder of their return trip to the Shortland Islands.


Aftermath and significance

Captain Kikunori Kijima—Gotō's chief of staff and commander of the bombardment force during the return trip to the Shortland Islands after Gotō's death in battle—claimed that his force had sunk two American cruisers and one destroyer. ''Furutaka''s Captain Araki Tsuto—who survived the sinking of his ship—blamed the loss of his cruiser on bad air reconnaissance and poor leadership from the 8th fleet staff under Admiral Mikawa. Although Gotō's bombardment mission failed, Jojima's reinforcement convoy was successful in delivering the crucial men and equipment to Guadalcanal. ''Aoba'' journeyed to

''Boise'' was under repair until 20 March 1943. Although a tactical victory for the U.S., Cape Esperance had little immediate strategic effect on the situation on Guadalcanal. Just two days later on the night of 13/14 October, the Japanese battleships and bombarded and almost destroyed Henderson Field, firing a total of 918 14-inch shells. One day after that, a large Japanese convoy successfully delivered 4,500 troops and equipment to the island. This was followed on the night of 14/15 October by a bombardment from heavy cruisers and which fired a combined 752 8-inch shells at the airfield, and then again during the night of 15/16 October, this time by heavy cruisers and firing 912 8-inch shells. The delivered troops and equipment helped complete Japanese preparations for the large land offensive scheduled to begin on 23 October.

that took place from 23–26 October. The Cape Esperance victory helped prevent an accurate U.S. assessment of Japanese skills and tactics in naval night fighting. The U.S. was still unaware of the range and power of Japanese torpedoes, the effectiveness of Japanese night optics, and the skilled fighting ability of most Japanese destroyer and cruiser commanders. Incorrectly applying the perceived lessons learned from this battle, U.S. commanders in future naval night battles in the Solomons consistently tried to prove that American naval gunfire was more effective than Japanese torpedo attacks. This belief was severely tested just two months later during the
