The Matanikau River of Guadalcanal , Solomon Islands , is located in the northwest part of the island. During the World War II Guadalcanal campaign , several significant engagements occurred between United States and Japanese forces near the river.
168-658: The Matanikau River was the scene of four important battles in the Guadalcanal Campaign of World War II, fought by elements of the United States Marine Corps and the Imperial Japanese Army from 19 August to 9 November 1942. 9°26′5″S 159°58′1″E / 9.43472°S 159.96694°E / -9.43472; 159.96694 This article related to a river in the Solomon Islands
336-413: A Type A midget submarine for transport to the waters off Oahu. The five I-boats left Kure Naval District on November 25, 1941. On December 6, they came to within 10 nmi (19 km; 12 mi) of the mouth of Pearl Harbor and launched their midget subs at about 01:00 local time on December 7. At 03:42 Hawaiian time, the minesweeper Condor spotted a midget submarine periscope southwest of
504-565: A Japanese naval base in the Shortland Islands. The Japanese destroyers were usually able to make round trips down "The Slot" ( New Georgia Sound ) to Guadalcanal and back in a single night throughout the campaign, which minimized their exposure to daytime Allied air attack. These runs became known as the "Tokyo Express" to Allied forces, and were labeled "rat transportation" by the Japanese. While troops could be transported in this manner, most of
672-580: A Japanese task force (the Striking Force ) of six aircraft carriers – Akagi , Kaga , Sōryū , Hiryū , Shōkaku , and Zuikaku – departed Hittokapu Bay on Etorofu (now Iterup) Island in the Kuril Islands , en route to a position northwest of Hawaii, intending to launch its 408 aircraft to attack Pearl Harbor: 360 for the two attack waves and 48 on defensive combat air patrol (CAP), including nine fighters from
840-514: A Marine aviator who was killed during the Battle of Midway. By 18 August the airfield was ready for operation. Five days' worth of food had been landed from the transports, which, along with captured Japanese provisions, gave the Marines a total of 14 days' supply of food. To conserve supplies, the troops were limited to two meals per day. Allied troops encountered a severe strain of dysentery soon after
1008-609: A base, Japanese long-range bombers could threaten the sea lines of communication and maritime trade & transportation routes from the west coast of the Americas to the populous east coast of Australia. By August, the Japanese had about 900 naval troops on Tulagi and nearby islands, and 2,800 personnel (including 2,200 Korean forced laborers and trustees, as well as Japanese construction specialists) on Guadalcanal. These bases were meant to protect Japan's major naval base at Rabaul , threaten Allied supply and communication lines, and establish
1176-601: A consequence, Japan needed access to strategically important resources (e.g. iron, oil) that could not be extracted at sufficient levels in the home islands. Although Japan had begun to take a hostile stance against the United States after the rejection of the Racial Equality Proposal , the relationship between the two countries was cordial enough that they remained trading partners. Tensions did not seriously grow until Japan's invasion of Manchuria in 1931 . Over
1344-570: A failed attack on Port Moresby over the Kokoda track . The second major Japanese offensive was stopped at the Battle of Midway . Both sides suffered significant losses in carrier aircraft and aircrew during these engagements. Crucially, while the Americans were able to reconstitute their naval air strength in relatively short order, the Japanese ultimately proved unable to do so. These strategic victories allowed
1512-529: A few units available to allocate to Guadalcanal. Of these, the 35th Infantry Brigade under Major General Kiyotake Kawaguchi was at Palau , the 4th (Aoba) Infantry Regiment under Major General Yumio Nasu was in the Philippines and the 28th (Ichiki) Infantry Regiment, under the command of Colonel Kiyonao Ichiki , was berthed on transport ships near Guam . These units began to move towards Guadalcanal via Truk and Rabaul immediately, but Ichiki's regiment, being

The Japanese planes were approaching from a direction very close (only a few degrees difference) to the bombers, and while the operators had never seen a formation as large on radar, they neglected to tell Tyler of its size. Tyler, for security reasons, could not tell
1848-526: A peace compromise. Striking the Pacific Fleet at anchor in Pearl Harbor had two distinct disadvantages: the targeted ships would be in very shallow water, so it would be relatively easy to salvage and possibly repair them, and most of the crews would survive the attack since many would be on shore leave or would be rescued from the harbor. A further important disadvantage was the absence of all three of

In 1992, 2000, and 2001 Hawaii Undersea Research Laboratory 's submersibles found the wreck of the fifth midget submarine lying in three parts outside Pearl Harbor. The wreck was in the debris field where much surplus American equipment had been dumped after the war, including vehicles and landing craft. Both of its torpedoes were missing. This correlates with reports of two torpedoes fired at

Soon after the patrol landed, a nearby platoon of Japanese naval troops attacked it and almost completely wiped it out. In response, on 19 August, Vandegrift sent three companies of the U.S. 5th Marine Regiment to attack the Japanese troop concentration west of
2352-559: A repeat of the disastrous defeat at Savo Island suffered by Australian and American surface vessels on 9 August. Transport Division 12 (Trans Div 12), consisting of six obsolete World War I-era Wickes -class destroyers converted to high-speed transports , were the most heavily armed U.S. surface ships operating in Ironbottom Sound during this time. Their torpedo tubes were retrofitted to hold landing craft boats , enough to carry over 100 extra Marines for rapid transportation. They landed

The commander of the Allied expeditionary force was U.S. Vice Admiral Frank Fletcher , Commander of Task Force 61 (whose flag was on the aircraft carrier USS Saratoga ). Commanding the amphibious forces was U.S. Rear Admiral Richmond K. Turner . Vandegrift led the 16,000 Allied (primarily U.S. Marine) infantry earmarked for
2688-593: A staging area for a planned offensive against Fiji , New Caledonia and Samoa ( Operation FS ). The Japanese planned to deploy 45 fighters and 60 bombers to Guadalcanal. In the overall strategy for 1942, these aircraft would provide ground-based air cover for Japanese naval forces advancing farther into the South Pacific. The Allied plan to invade the southern Solomons was conceived by U.S. Admiral Ernest King , Commander in Chief, United States Fleet . He proposed

While it was viewed by a number of senior American government and military officials as a very strong indicator negotiations were likely to be terminated and that war might break out at any moment, it neither declared war nor severed diplomatic relations. A declaration of war was printed on the front page of Japan's newspapers in the evening edition of December 8 (late December 7 in

Despite these preparations, Emperor Hirohito did not approve the attack plan until November 5, after the third of four Imperial Conferences called to consider the matter. At first, he hesitated to engage in war but eventually authorized

The Japanese military leadership referred to
4032-908: The European theater . An early obstacle was the desire of both the U.S. Army and the Roosevelt administration to initiate offensive action in Europe prior to a large-scale operation in the Pacific. In addition, it was initially unclear who would command the campaign: Tulagi lay in the area under the command of General Douglas MacArthur , whereas the Santa Cruz Islands lay in Admiral Chester W. Nimitz 's Pacific Ocean Area , which would also supply almost all Allied offensive forces that would be staged, supplied and covered from that area. Both problems were overcome, and

On the night of 12 September, Kawaguchi's 1st Battalion attacked the Raiders between the Lunga River and ridge, forcing one Marine company to fall back to
4536-627: The Nanking Massacre swung Western public opinion sharply against Japan. The United States unsuccessfully proposed a joint action with the United Kingdom to blockade Japan. In 1938, following an appeal by President Roosevelt, American companies stopped providing Japan with implements of war. In 1940, Japan invaded French Indochina , attempting to stymie the flow of supplies reaching China. The United States halted shipments of airplanes, parts, machine tools , and aviation gasoline to Japan, which

While there were historical precedents for the unannounced military action by Japan, the lack of any formal warning, as required by the Hague Convention of 1907 , and the perception that the attack had been unprovoked, led then- President Franklin D. Roosevelt , in

Over the course of seven hours, Japan conducted coordinated attacks on the U.S.-held Philippines , Guam , and Wake Island ; and on the British Empire in Malaya , Singapore , and Hong Kong . The attack on Pearl Harbor started at 7:48 a.m. Hawaiian time (6:18 p.m. GMT).

6384-596: The "First Battle of the Matanikau", was the first of several major actions around the Matanikau River during the campaign. On 20 August, the escort carrier USS Long Island delivered a squadron of 19 Grumman F4F Wildcats and a squadron of 12 Douglas SBD Dauntlesses to Henderson Field. The airfield's rudimentary nature meant that carrier aircraft, designed for rough landings on flight decks at sea, were more suited for use on Henderson Field than ground-based planes. The aircraft based at Henderson became known as
6552-460: The "Guadalcanal matter" was resolved. Hyakutake prepared to send more troops to Guadalcanal for another attempt to recapture Henderson Field. As the Japanese regrouped west of the Matanikau, the U.S. forces concentrated on shoring up and strengthening their Lunga defenses. On 14 September Vandegrift moved another battalion ( 3rd Battalion, 2nd Marine Regiment ) from Tulagi to Guadalcanal. On 18 September, an Allied naval convoy delivered 4,157 men from

7560-425: The Allies, who captured Tulagi and Florida, as well as the airfield—later named Henderson Field —that was under construction on Guadalcanal. Surprised by the Allied offensive, the Japanese made several attempts between August and November to retake Henderson Field. Three major land battles, seven large naval battles (five nighttime surface actions and two carrier battles), and almost daily aerial battles culminated in
7728-556: The American carrier Wasp , after refueling, positioned herself east of Guadalcanal, expecting Japanese movement to the area. No Japanese forces made any movement towards the area, however, and the Wasp was left idle. The Americans had won a modest tactical victory with the destruction of the Ryūjō, destroying some 75 Japanese aircraft while losing 25 of their own. The forced withdrawal of Tanaka's troop convoy also bought valuable breathing room for

From the Japanese point of view, it was seen as a preemptive strike "before the oil gauge ran empty."

Marshall , gave the operation his full support, despite MacArthur's command being unable to directly assist in the operation and the U.S. Navy taking full operational responsibility. As a result, and in order to preserve the unity of command, the boundary between MacArthur's South West Pacific Area and Nimitz's Pacific Ocean Area was shifted 60 miles (97 km) to 360 miles (580 km) to

At this stage, as the intensity of the battle reached its apex, small groups of Japanese soldiers managed to break through Edson's lines, with some reaching the edge of the airfield itself. Several Japanese soldiers were killed as they attempted to climb onto and destroy parked aircraft, and General Vandegrift's command post even came under direct attack at dawn, with several Japanese infiltrators killed within sight of
9576-479: The Marines suffering 104. On 15 September at Rabaul, Hyakutake learned of Kawaguchi's defeat and forwarded the news to Imperial General Headquarters in Japan. In an emergency meeting, the senior Japanese IJA and IJN command staffs concluded that "Guadalcanal might develop into the decisive battle of the war". The results of the battle now began to exert significant strategic impact on Japanese operations in other areas of

One company attacked across the sandbar at the mouth of the Matanikau River while another crossed the river 1,000 meters (1,100 yd) inland and attacked the Japanese forces located in Matanikau village. The third landed by boat further west and attacked Kokumbuna village. After briefly occupying the two villages, the three Marine companies returned to the Lunga perimeter, having killed about 65 Japanese soldiers while losing four Marines. This action, sometimes referred to as

The American War Plan Orange had envisioned defending the Philippines with an elite force of 40,000 men; this option was never implemented due to opposition from Douglas MacArthur , who felt he would need a force ten times that size. By 1941, American planners expected to have to abandon the Philippines at the outbreak of war. Late that year, Admiral Thomas C. Hart , commander of

The American counter-proposal of November 26 (November 27 in Japan), the Hull note , required Japan to completely evacuate China without conditions and conclude non-aggression pacts with Pacific powers. On November 26 in Japan,
12600-460: The aircraft carrier USS Wasp was scuttled after being struck by torpedoes from the Japanese submarine I-19 southeast of Guadalcanal. This stretched Allied naval airpower thin, with only one aircraft carrier ( USS Hornet ) remaining in operation in the entire South Pacific Area. Vandegrift also made some changes in the senior leadership of his combat units, transferring several officers who did not meet his performance standards off
12768-504: The aircraft carriers and return to combat. Fighters were to assume CAP duties where needed, especially over American airfields. Before the attack commenced, the Imperial Japanese Navy launched reconnaissance floatplanes from heavy cruisers Chikuma and Tone , to scout Oahu and Lahaina Roads, Maui, respectively, with orders to report on American fleet composition and location. Reconnaissance aircraft flights risked alerting
12936-446: The airfield and surrounding area. During the landing operations on 7 and 8 August, Rabaul-based Japanese naval aircraft under the command of Yamada Sadayoshi attacked the Allied amphibious forces several times, setting fire the transport USS George F. Elliott (which sank two days later) and heavily damaging the destroyer USS Jarvis . Over the course of two days of air attacks, Japanese air units lost 36 aircraft, while
13104-536: The airfield by 16:00 on 8 August. The Japanese naval construction units and combat troops, under the command of Captain Kanae Monzen, had panicked after coming under naval bombardment and aerial bombing, and had abandoned the airfield and fled about 3 miles (5 km) west to the Matanikau River and Point Cruz area. Japanese troops left behind food, supplies, intact construction equipment and vehicles, and 13 dead at
13272-428: The airfield, moving what supplies had been brought ashore within the perimeter, and completing the construction of the airfield. Over four days of intense effort, the supplies were moved from the landing beaches to dispersed dumps within the defensive perimeter. Work began on the airfield immediately, mainly using captured Japanese equipment. On 12 August the airfield was named Henderson Field after Lofton R. Henderson ,
13440-443: The amphibious landings. The troops sent to Guadalcanal were fresh from military training, armed with legacy bolt-action M1903 Springfield rifles and a meager 10-day supply of ammunition. Because of the need to get the troops into battle quickly, the Allied planners had reduced their supplies from 90 days to only 60. The men of the 1st Marine Division began referring to the coming battle as "Operation Shoestring". Bad weather allowed
13608-413: The area, positioned themselves to attack Henderson Field. These ships were spotted by two American destroyer-transports, who believed at first that they were a submarine. A U.S. patrol plane also misidentified the destroyers as an enemy submarine and dropped flares over the area, accidentally silhouetting Little and Gregory in the nighttime conditions. The Japanese destroyers immediately fired on and sunk
13776-485: The area. The Japanese lost the Ryūjō , along with dozens of carrier aircraft and most of their aircrew; meanwhile, the Americans lost a handful of planes and Enterprise was damaged, requiring two months to repair in Hawaii. Unable to safely land on Enterprise's ruined flight deck, much of her remaining aircraft instead flew to Guadalcanal and reinforced the beleaguered American air units at Henderson Field. Concurrently to
13944-550: The attack as the Hawaii Operation and Operation AI , and as Operation Z during its planning. The Empire of Japan 's attack on Pearl Harbor was preceded by months of negotiations between the United States and Japan over the future of the Pacific . Japanese demands included that the United States end its sanctions against Japan , cease aiding China in the Second Sino-Japanese War , and allow Japan to access
14112-407: The attack on Pearl Harbor that was declassified in the 1990s and publicized in the 2000s to the public, shows the fifth midget submarine firing a torpedo at West Virginia and another at Oklahoma . These torpedoes were twice the size of the aerial torpedoes so it was possible that both torpedoes heavily contributed to the sinkings of both ships and especially helped to capsize Oklahoma as Oklahoma
14280-410: The attack. Ammunition lockers were locked, aircraft parked wingtip to wingtip in the open to prevent sabotage, guns unmanned (none of the Navy's 5"/38s , only a quarter of its machine guns, and only four of 31 Army batteries got in action). Despite this low alert status , many American military personnel responded effectively during the attack. Ensign Joseph Taussig Jr. , aboard Nevada , commanded
14448-481: The attention of American pilots. The aircraft from the two fleet carriers would then attack the American fleet while it lacked air cover. Simultaneously, the U.S. carrier task force under Fletcher approached Guadalcanal to counter the Japanese offensive efforts. On 24 August, the two carrier forces located and launched strikes against the other. The Japanese had two fleet carriers, the Shōkaku and Zuikaku , as well as
14616-660: The auspices of Admiral Isoroku Yamamoto , then commanding Japan's Combined Fleet . He won assent to formal planning and training for an attack from the Imperial Japanese Navy General Staff only after much contention with Naval Headquarters, including a threat to resign his command. Full-scale planning was underway by early spring 1941, primarily by Rear Admiral Ryūnosuke Kusaka , with assistance from Commander Minoru Genda and Yamamoto's Deputy Chief of Staff, Captain Kameto Kuroshima. The planners studied
14784-709: The brigade's supply base at Taivu. Meanwhile, native scouts under the direction of Martin Clemens , a coastwatcher officer in the British Solomon Islands Protectorate Defence Force and the British district officer for Guadalcanal, brought reports to the U.S. Marines of Japanese troops at Taivu near the village of Tasimboko. Edson subsequently planned a raid on the Japanese troop concentration at Taivu. On 8 September, after being dropped off near Taivu by boat, Edson's men captured Tasimboko and forced
14952-413: The captured documents indicated that at least 3,000 Japanese troops were on the island, planning to initiate a large-scale ground assault on the airfield in short order. Edson, along with Colonel Gerald C. Thomas , Vandegrift's operations officer, correctly anticipated that the main Japanese attack would fall upon Lunga Ridge, a narrow, grassy, 1,000-yard-long (900 m) coral ridge that ran parallel to
15120-527: The carrier air battle, on 25 August, Tanaka's convoy (headed by the flagship Jintsū ) was attacked near Taivu Point by Cactus Air Force aircraft based at Henderson Field. After suffering heavy damage during the battle, including the sinking of one of the transports, the convoy was forced to divert to the Shortland Islands in the northern Solomons in order to transfer the surviving troops to destroyers for later delivery to Guadalcanal. A Japanese transport
15288-466: The closest, arrived in the area first. A "First Element" of Ichiki's unit, consisting of about 917 soldiers, was landed by IJN destroyers at Taivu Point, east of the Lunga perimeter, after midnight on 19 August, then conducted a 9-mile (14 km) night march west toward the Marine perimeter. Underestimating the strength of Allied forces on Guadalcanal, Ichiki's unit conducted a nighttime frontal assault on Marine positions at Alligator Creek (often called
15456-474: The command of Colonel Akinosuke Oka , to Kamimbo, west of the Lunga perimeter. On 7 September, Kawaguchi issued his attack plan to "rout and annihilate the enemy in the vicinity of the Guadalcanal Island airfield". Kawaguchi's plan called for the forces under his command, split into three divisions, to approach the Lunga perimeter inland, culminating with a surprise night attack. Oka's forces would attack
15624-424: The commander of the 1st Marine Aircraft Wing , U.S. Marine Brigadier General Roy Geiger , arrived with his staff and took command of all air operations at Henderson Field. Air battles between the Allied aircraft at Henderson and Japanese bombers and fighters from Rabaul continued almost daily. Between 26 August and 5 September, the U.S. lost about 15 aircraft to the Japanese's approximately 19. More than half of
15792-680: The commanding officer of one of the submarines, was captured. Japan declared war on the United States and the British Empire later that day (December 8 in Tokyo ), but the declarations were not delivered until the following day. The British government declared war on Japan immediately after learning that their territory had also been attacked, while the following day (December 8), the United States Congress declared war on Japan . On December 11, though they had no formal obligation to do so under
15960-430: The course of the previous days, both by Allied submarines and aerial reconnaissance, but a combination of misidentification of ships and the Allied leadership's dismissal of Japanese night fighting capability contributed to an air of complacence and ignorance among the Allied surface fleet that proved disastrous. Japanese submarine activity and air attack continued to be the main source of concern to Turner and his staff, not
16128-492: The day before the note's delivery, the Japanese task force left port for Pearl Harbor . The Japanese intended the attack as a preventive action to keep the United States Pacific Fleet from interfering with their planned military actions in Southeast Asia against overseas territories of the United Kingdom , the Netherlands , and the United States. Over the course of seven hours, there were coordinated Japanese attacks on
16296-565: The day, persisted for the next several months of the campaign. Between 29 August and 4 September, Japanese light cruisers, destroyers, and patrol boats were able to land almost 5,000 troops at Taivu Point, including most of the 35th Infantry Brigade, much of the Aoba (4th) Regiment, and the rest of Ichiki's regiment. General Kawaguchi, who landed at Taivu Point on 31 August, was placed in command of all Japanese forces on Guadalcanal. A barge convoy took another 1,000 soldiers of Kawaguchi's brigade, under
16464-602: The deadliest event ever recorded in Hawaii. It was also the deadliest foreign attack against the United States in its history until the September 11 attacks of 2001. Important base installations, such as the power station, dry dock , shipyard , maintenance, and fuel and torpedo storage facilities, as well as the submarine piers and headquarters building (also home of the intelligence section ) were not attacked. Japanese losses were light: 29 aircraft and five midget submarines were lost, and 129 servicemen killed. Kazuo Sakamaki ,
16632-425: The decisive Naval Battle of Guadalcanal in early November, with the defeat of the last Japanese attempt to bombard Henderson Field from the sea and to land enough troops on the island to retake it. In December, the Japanese abandoned their efforts to retake Guadalcanal and evacuated their remaining forces by 7 February 1943, in the face of an offensive by the U.S. Army 's XIV Corps . The Battle of Rennell Island ,
16800-451: The eight United States Navy battleships present, all were damaged and four were sunk. All but USS Arizona were later raised, and six were returned to service and went on to fight in the war. The Japanese also sank or damaged three cruisers , three destroyers , an anti-aircraft training ship, and one minelayer . More than 180 US aircraft were destroyed. A total of 2,393 Americans were killed and 1,178 others were wounded, making it
16968-492: The embattled Allied troops on Guadalcanal. While the Enterprise was taken out of action for repair for several months, she would return to sea later in the campaign. Regardless, the temporary loss of the Enterprise was offset by the timely arrival of the carrier Hornet . Additionally, the reinforcement of Henderson Field by Enterprise ' s orphaned carrier aircraft served bolstered flagging ground-based Allied air strength in
17136-413: The evening of 8 August. As a result of the loss of carrier-based air cover, Turner decided to withdraw his ships from Guadalcanal, even though less than half of the supplies and heavy equipment needed by the troops ashore had been unloaded. Turner planned to unload as many supplies as possible on Guadalcanal and Tulagi throughout the night of 8 August, and then depart with his ships early on 9 August. As
17304-404: The eventual goal was the American reconquest of the Philippines, from which American forces had been evicted in early 1942. The U.S. Joint Chiefs of Staff created the South Pacific theater, with Vice Admiral Robert L. Ghormley taking command on 19 June, to direct the offensive in the Solomons. Nimitz, based at Pearl Harbor, was designated as overall Allied commander-in-chief for Allied forces in
17472-413: The first Marines onto Tulagi and later on Guadalcanal, conducted special operations missions with Marine Raiders , participated in anti-submarine warfare, and provided covering fire for the Marines on Guadalcanal. They also directly delivered crucial supplies to the Marines that helped to construct Henderson Field and to maintain the aircraft stationed there. On 30 August USS Colhoun (APD-2)
17640-532: The first target; instead, they expected the Philippines to be attacked first. This presumption was due to the threat that the air bases throughout the country and the naval base at Manila posed to sea lanes, as well as to the shipment of supplies to Japan from territory to the south. They also incorrectly believed that Japan was not capable of mounting more than one major naval operation at a time. The Japanese attack had several major aims. First, it intended to destroy important American fleet units, thereby preventing
17808-449: The first wave approached Oahu, it was detected by United States Army SCR-270 radar positioned at Opana Point near the island's northern tip. This post had been in training mode for months, but was not yet operational. The operators, Privates George Elliot Jr. and Joseph Lockard , reported a target to Private Joseph P. McDonald , a private stationed at Fort Shafter 's Intercept Center near Pearl Harbor. Lieutenant Kermit A. Tyler ,
17976-476: The first wave. The first wave was to be the primary attack, while the second wave was to attack carriers as its first objective and cruisers as its second, with battleships as the third target. The first wave carried most of the weapons designed to attack capital ships, mainly specially adapted Type 91 aerial torpedoes which were designed with an anti-roll mechanism and a rudder extension that let them operate in shallow water. The aircrews were ordered to select
18144-567: The general. Nonetheless, Kawaguchi's units were spent, and the main Japanese attack on Edson's positions ground to a halt. The supporting attacks by the Kuma Battalion and Oka's unit at other locations on the Lunga perimeter were likewise defeated. On 14 September, Kawaguchi led the survivors of his shattered brigade on a five-day march west to the Matanikau Valley to join with Oka's unit. In total Kawaguchi's forces lost about 850 killed, with
18312-486: The ground. Almost none were actually ready to take off to defend the base. Eight Army Air Forces pilots managed to get airborne during the attack, and six were credited with downing at least one Japanese aircraft during the attack: 1st Lieutenant Lewis M. Sanders and 2nd Lieutenants Philip M. Rasmussen , Kenneth M. Taylor , George S. Welch , Harry W. Brown , and Gordon H. Sterling Jr. Of 33 Consolidated PBY Catalinas in Hawaii, 30 were destroyed, while three on patrol at
18480-499: The growing Allied airpower at Henderson Field (which was further reinforced on September 11-12 by 24 Wildcats that had been made homeless by the torpedoing of the carrier Saratoga in early September by IJN submarine I-26 ) meant that any Japanese vessel within range (200 miles or 320 kilometres) of Guadalcanal in daylight was at great risk from air attack. This tactical situation, wherein Japanese naval forces operated freely at night and Allied aircraft enjoyed local air superiority during
18648-431: The harbor entrance and again on the east side of Oahu, where it was captured on December 8. Ensign Kazuo Sakamaki swam ashore and was captured by Hawaii National Guard Corporal David Akui , becoming the first Japanese prisoner of war . A fourth had been damaged by a depth charge attack and was abandoned by its crew before it could fire its torpedoes. It was found outside the harbor in 1960. Japanese forces received
18816-581: The heavy equipment and supplies, such as heavy artillery, vehicles, food and ammunition, could not. In addition, this activity tied up destroyers that the IJN desperately needed to escort convoys elsewhere in the Pacific. The Byzantine nature of the Japanese navy's command setup in the region exacerbated these logistical problems; Tanaka was receiving contradictory orders from both the Combined Fleet headquarters as well as two rival subordinate naval commands at Rabaul,
18984-421: The highest-value targets (battleships and aircraft carriers ) or, if these were not present, any other high-value ships (cruisers and destroyers). First-wave dive bombers were to attack ground targets. Fighters were ordered to strafe and destroy as many parked aircraft as possible to ensure they did not intercept the bombers, especially in the first wave. When the fighters' fuel got low, they were to refuel aboard
19152-613: The immediate area of Henderson Field. This, combined with the fact that the Japanese navy did not systematically rotate their veteran pilots out of combat zones, steadily exhausted & depleted Japanese airpower in the region. From a strategic standpoint, the overall quality of Japanese aviation in the Solomons deteriorated as worn-out veteran pilots were replaced by inexperienced aircrew with minimal combat experience. Australian coastwatchers on Bougainville and New Georgia islands were often able to provide Allied forces on Guadalcanal with advance notice of inbound Japanese air strikes, allowing
19320-495: The island and promoting junior officers who had proven themselves to take their place. One of these was the recently promoted Colonel Merritt Edson, who was placed in command of the 5th Marine Regiment. Attack on Pearl Harbor Japanese victory 1941 1942 Second Sino-Japanese War The attack on Pearl Harbor was a surprise military strike by the Imperial Japanese Navy Air Service on
19488-430: The island, sortied from both Truk and Rabaul. Three slow transport ships departed from Truk on 16 August, carrying the remaining 1,400 soldiers from Ichiki's (28th) Infantry Regiment plus 500 naval marines from the 5th Yokosuka Special Naval Landing Force . The transports were guarded by 13 warships commanded by Japanese Rear Admiral Raizō Tanaka , who planned to land the troops on Guadalcanal on 24 August. To cover
19656-431: The landing of these troops and provide support for the operation to retake Henderson Field from Allied forces, Yamamoto directed Chūichi Nagumo to sortie with a carrier force from Truk on 21 August and sail toward the southern Solomon Islands. Nagumo's force included three carriers and 30 other warships. Yamamoto would send the light carrier Ryūjō to act as bait, ahead of the rest of the Japanese fleet, in order to draw
19824-462: The landings, with one in five Marines afflicted by mid-August. Although some of the Korean construction workers surrendered to the Marines, most of the remaining Japanese and Korean personnel gathered just west of the Lunga perimeter on the west bank of the Matanikau River and subsisted mainly on coconuts. A Japanese naval outpost was also located at Taivu Point, about 35 kilometers (22 mi) east of
19992-478: The last major naval engagement of the campaign, served to secure sufficient protection for much of the remaining Japanese force, by now significantly degraded by disease, starvation and combat casualties, to evacuate safely. The campaign followed the successful Allied defensive actions at the Battle of the Coral Sea and the Battle of Midway in May and June 1942. Along with the battles at Milne Bay and Buna–Gona ,
20160-464: The latter perceived as an unfriendly act. The United States did not stop oil exports, however, partly because of the prevailing sentiment in Washington that given Japanese dependence on American oil, such an action was likely to be considered an extreme provocation. In mid-1940, President Franklin D. Roosevelt moved the Pacific Fleet from San Diego to Hawaii. He also ordered a military buildup in
20328-603: The light carrier Ryūjō , with a total of 177 carrier-based aircraft. The American forces had two carriers, the Saratoga and Enterprise , and their 176 aircraft. The Japanese light carrier Ryūjō , offered as bait to Allied naval aircraft, was hit by several 1,000-pound (450 kg) bombs and an aerial torpedo; she was abandoned by her crew and sank that night. The two Japanese fleet carriers were not attacked, but Japanese aircraft successfully attacked Enterprise , badly damaging her flight deck. Both fleets subsequently retreated from
20496-459: The magnitude of his defeat, rather than dying in combat. In total, 789 of the original 917 members of the Ichiki Regiment's First Element were killed in the battle. About 30 survived the battle and joined Ichiki's rear guard of about 100, and these 128 Japanese returned to Taivu Point, notified 17th Army headquarters of their defeat and awaited further reinforcements and orders from Rabaul. As
20664-504: The meeting, warning that it was the only way to preserve the conciliatory Konoe government and peace in the Pacific. However, his recommendation was not acted upon. The Konoe government collapsed the following month when the Japanese military rejected a withdrawal of all troops from China. Japan's final proposal, delivered on November 20, offered to withdraw from southern Indochina and to refrain from attacks in Southeast Asia, so long as
20832-399: The message took too long for the Japanese ambassador to deliver it at 1:00 p.m. Washington time, as ordered, and consequently the message was not presented until more than one hour after the attack had begun — but American code breakers had already deciphered and translated most of the message hours before it was scheduled to be delivered. The final part of the message
21000-627: The naval and seaplane bases on the three islands fiercely resisted the Marine landings. With some difficulty, the Marines secured all three islands: Tulagi on 8 August, and Gavutu and Tanambogo by 9 August. The Japanese defenders were killed almost to the last man, and the Marines suffered 248 casualties. In contrast to Tulagi, Gavutu, and Tanambogo, the landings on Guadalcanal encountered much less resistance. At 09:10 on 7 August, Vandegrift and 11,000 U.S. Marines came ashore on Guadalcanal between Koli Point and Lunga Point. Advancing towards Lunga Point, they encountered scant Japanese resistance and secured
21168-545: The next day. The initial goals of the Japanese leadership were to neutralize the U.S. Navy , seize territories rich in natural resources, and establish strategic military bases with which to defend Japan's empire in the Pacific Ocean and Asia. Initially, Japanese forces captured the Philippines, Thailand, Malaya , Singapore, Burma, the Dutch East Indies , Wake Island , Gilbert Islands , New Britain and Guam . The U.S.
21336-520: The next decade, Japan expanded into China , leading to the Second Sino-Japanese War in 1937. Japan spent considerable effort trying to isolate China and endeavored to secure enough independent resources to attain victory on the mainland. The " Southern Operation " was designed to assist these efforts. Starting in December 1937, events such as the Japanese attack on USS Panay , the Allison incident , and
21504-693: The night, so the Marines returned to the Lunga perimeter by boat. These actions resulted in the loss of 20 Japanese and 3 Marines. Small Allied naval convoys arrived at Guadalcanal on 23 and 29 August, and 1 and 8 September to provide the Marines at Lunga with more food, ammunition, aircraft fuel, aircraft technicians, and other supplies. The convoy on 1 September also brought 392 Seabees to maintain and improve Henderson Field. In addition, on 3 September, Marine Aircraft Group 25 began airlifting high-priority cargo, including personnel, aviation gasoline, munitions, and other supplies, to Henderson Field. By 23 August, Kawaguchi's 35th Infantry Brigade reached Truk and
21672-590: The offensive in order to deny the use of the islands to the Japanese as bases from which the supply routes between the United States and Australia could be threatened, and to use them as starting points for further Allied offensives in the South Pacific. With U.S. President Franklin D. Roosevelt 's tacit consent, King also advocated for an invasion of Guadalcanal. Due to the Roosevelt administration's support for Great Britain's proposal that priority be given to defeating Germany before Japan , Allied commanders in Pacific theater had to compete for personnel and resources with
21840-666: The only fire department members on American soil to be attacked by a foreign power in history. Fireman Harry Tuck Lee Pang of Engine 6 was killed near the hangars by machine-gun fire from a Japanese plane. Captains Thomas Macy and John Carreira of Engine 4 and Engine 1, respectively, died while battling flames inside the hangar after a Japanese bomb crashed through the roof. An additional six firefighters were wounded by Japanese shrapnel. The wounded later received Purple Hearts (originally reserved for service members wounded by enemy action while partaking in armed conflicts) for their peacetime actions that day on June 13, 1944;
22008-535: The opening line of his speech to a Joint Session of Congress the following day, to famously label December 7, 1941, " a date which will live in infamy ". War between the Empire of Japan and the United States was seen as a possibility since the 1920s. Japan had been wary of American territorial and military expansion in the Pacific and Asia since the late 1890s, followed by the annexation of islands, such as Hawaii and
22176-484: The operators of the six B-17s that were due (even though it was widely known). As the first wave approached Oahu, they encountered and shot down several American aircraft. At least one of these radioed a somewhat incoherent warning. Other warnings from ships off the harbor entrance were still being processed or awaiting confirmation when the Japanese air assault began at 7:48 a.m. Hawaiian time (3:18 a.m. December 8 Japanese Standard Time , as kept by ships of
22344-437: The other Tulagi, Florida, and other nearby islands. Allied warships bombarded the invasion beaches, while U.S. carrier aircraft bombed Japanese positions on the target islands and destroyed 15 Japanese seaplanes at their base near Tulagi. Tulagi and two nearby small islands, Gavutu and Tanambogo , were assaulted by 3,000 U.S. Marines under the command of Brigadier General William Rupertus . The 886 IJN personnel manning
22512-427: The other two islands and located to the south across the soon-to-be-named Ironbottom Sound , was added when it was discovered the Japanese were constructing an airbase there. The Imperial Japanese Navy (IJN) had occupied Tulagi in May 1942 and had constructed a seaplane base nearby. Allied concern grew when, in early July, the IJN began constructing a large airfield at Lunga Point on nearby Guadalcanal. From such
22680-417: The overmatched American ships. 65 men from Little were killed and 24 men from Gregory were killed, including the commanding officer of Transport Division 12 and the commanding officers of both ships. Throughout August, small numbers of American aircraft and their crews continued to arrive at Guadalcanal. By the end of August, 64 planes of various types were stationed at Henderson Field. On 3 September,
22848-486: The peace of the Pacific through cooperation with the American Government has finally been lost. The Japanese Government regrets to have to notify hereby the American Government that in view of the attitude of the American Government it cannot but consider that it is impossible to reach an agreement through further negotiations. United States naval intelligence officers were alarmed by the unusual timing for delivering
23016-439: The perimeter from the west, while Ichiki's Second Echelon, renamed the Kuma Battalion, would attack from the east. The main attack would be conducted from the jungle south of the Lunga perimeter by Kawaguchi's "Center Body", numbering 3,000 men in three battalions. By 7 September, most of Kawaguchi's troops had departed Taivu to begin marching towards Lunga Point along the coastline. About 250 Japanese troops remained behind to guard
23184-405: The reality that their ships could not safely operate in the Solomons in the daytime without first suppressing Allied airpower at Henderson Field. For six weeks, from early August to the end of September, the U.S. Navy largely avoided the waters off Tulagi and Guadalcanal, and was ordered not to resupply the Marines or provide escort duty for slow transport ships, as American naval commanders feared
23352-465: The region; meanwhile, ground-based Japanese pilots based at Rabaul were forced to undertake a grueling day-long round trip flight in order to make their attacks. Combined, this rendered daylight supply runs to Guadalcanal impossible for the Japanese. Only weeks before this, the Japanese had total control of the sea in this particular region; now they were forced to make supply runs only under the cover of darkness. Japanese naval commanders began to recognize
23520-529: The resources of the Dutch East Indies . Anticipating a negative response, Japan sent out its naval attack groups in November 1941 just prior to receiving the Hull note —which states the United States desire that Japan withdraw from China and French Indochina . Japan intended the attack as a preventive action. Its aim was to prevent the United States Pacific Fleet from interfering with its planned military actions in Southeast Asia against overseas territories of
23688-409: The ridge before the Japanese halted their attack for the night. The next night Kawaguchi faced Edson's 840 Raiders with 3,000 troops of his brigade, reinforced by an assortment of light artillery. The Japanese began their attack just after nightfall, with Kawaguchi's 1st Battalion assaulting Edson's right flank just to the west of the ridge. After breaking through the Marine lines, the battalion's assault
23856-608: The second wave attacked the Army Air Forces' Bellows Field , near Kaneohe on the windward side of the island, and Ford Island. The only aerial opposition came from a handful of P-36 Hawks , P-40 Warhawks and some SBD Dauntless dive bombers from the carrier Enterprise . In the first-wave attack, about eight of the forty-nine 800‑kg (1760 lb) armor-piercing bombs dropped hit their intended battleship targets. At least two of those bombs broke up on impact, another detonated before penetrating an unarmored deck, and one
24024-584: The ship's antiaircraft guns and was severely wounded but remained at his post. Lieutenant Commander F. J. Thomas commanded Nevada in the captain's absence and got her underway until the ship was grounded at 9:10 a.m. One of the destroyers, Aylwin , got underway with only four officers aboard, all ensigns, none with more than a year's sea duty; she operated at sea for 36 hours before her commanding officer managed to get back aboard. Captain Mervyn Bennion , commanding West Virginia , led his men until he
24192-564: The task of retaking Guadalcanal to the Imperial Japanese Army's (IJA) 17th Army , a corps -sized command based at Rabaul under the command of Lieutenant General Harukichi Hyakutake . The army was to be supported by Japanese naval units, including the Combined Fleet under the command of Isoroku Yamamoto , which was headquartered at Truk . The 17th Army, at that time heavily involved in the Japanese campaign in New Guinea , had only
24360-521: The termination of negotiations ... and they clearly prevailed." In any event, even if the Japanese had decoded and delivered the 14-Part Message before the beginning of the attack, it would not have constituted either a formal break of diplomatic relations or a declaration of war. The final two paragraphs of the message read: Thus the earnest hope of the Japanese Government to adjust Japanese-American relations and to preserve and promote
24528-413: The threat of Japanese surface action. As a result, during the Battle of Savo Island on the night of 9 August, Mikawa's force was able to surprise and sink one Australian and three American cruisers, as well as damage another American cruiser and two destroyers. The Japanese suffered only moderate damage to one cruiser. Despite this success, Mikawa was unaware that Fletcher was preparing to withdraw with
24696-471: The three firefighters killed did not receive theirs until December 7, 1984, on the 43rd anniversary of the attack. This made the nine men the only non-military firefighters to receive such an award in American history. Already damaged by a torpedo and on fire amidships, Nevada attempted to exit the harbor. She was targeted by many Japanese bombers as she got under way and sustained more hits from 250 lb (113 kg) bombs, which started further fires. She
24864-422: The transports continued to unload on the night of 8–9 August, two groups of screening Allied cruisers and destroyers, under the command of British Rear Admiral Victor Crutchley , were surprised and defeated by a Japanese force of seven cruisers and one destroyer from the 8th Fleet based at Rabaul and Kavieng , commanded by Japanese Vice Admiral Gunichi Mikawa . The 8th fleet had been sighted at least 5 times over
25032-586: The west, effective from 1 August 1942. Chief of Staff to the Commander in Chief William D. Leahy established two goals for 1942–1943: first, that Guadalcanal would be taken, in conjunction with an Allied offensive in New Guinea under MacArthur; and second, that the Admiralty Islands and Bismarck Archipelago , including the major Japanese base at Rabaul, would be captured as well. The directive held that
25200-449: Was a dud. Thirteen of the forty torpedoes hit battleships, while four hit other ships. Men aboard the ships awoke to the sounds of alarms, bombs exploding, and gunfire, prompting them to dress as they ran to General Quarters stations. (The famous message, "Air raid Pearl Harbor. This is not drill.", was sent from the headquarters of Patrol Wing Two, the first senior Hawaiian command to respond.) American servicemen were caught unprepared by
25368-445: Was bombed by Japanese high-altitude horizontal bombers and sank with the loss of 51 men. On 4–5 September, USS Little (APD-4) and USS Gregory (APD-3) had finished landing a complement of Marine Raiders back onto Guadalcanal and proceeded to patrol the area for submarines, which had been surfacing and shelling the Marines nightly. Three Japanese destroyers, who did not know that enemy surface ships were patrolling
25536-596: Was considered unusual for him. Additionally, he actively sought more information about the war plans. According to an aide, he openly displayed happiness upon hearing about the success of the surprise attacks. By late 1941, many observers believed that hostilities between the United States and Japan were imminent. A Gallup poll just before the attack on Pearl Harbor found that 52% of Americans expected war with Japan, 27% did not, and 21% had no opinion. While American Pacific bases and facilities had been placed on alert on many occasions, officials doubted Pearl Harbor would be
25704-407: Was cut down by fragments from a bomb which hit Tennessee , moored alongside. The second planned wave consisted of 171 planes: 54 B5Ns, 81 D3As, and 36 A6Ms, commanded by Lieutenant-Commander Shigekazu Shimazaki . Four planes failed to launch because of technical difficulties. This wave and its targets also comprised three groups of planes: The second wave was divided into three groups. One
25872-428: Was deliberately beached to avoid risking blocking the harbor entrance if she sank there. California was hit by two bombs and two torpedoes. The crew might have kept her afloat, but were ordered to abandon ship just as they were raising power for the pumps. Burning oil from Arizona and West Virginia was drifted down toward her and probably made the situation look worse than it was. The disarmed target ship Utah
26040-548: Was eventually stopped by Marine units occupying the northern section of the ridge. Two companies from Kawaguchi's 2nd Battalion charged up the southern edge of the ridge and pushed Edson's troops back to Hill 123, in the center section of the ridge. Throughout the night the Marines at this position, supported by a battery of howizers brought up from Lunga Point, turned back wave after wave of frontal Japanese infantry attacks, several of which devolved into hand-to-hand combat. The weight of these repeated assaults eventually pressed
26208-413: Was holed by a torpedo. The light cruiser Honolulu was damaged but remained in service. The repair vessel Vestal , moored alongside Arizona , was heavily damaged and beached. The seaplane tender Curtiss was also damaged. The destroyer Shaw was badly damaged when two bombs penetrated her forward magazine. Of the 402 American aircraft in Hawaii, 188 were destroyed and 159 damaged, 155 of them on
26376-453: Was holed twice by torpedoes. West Virginia was hit by seven torpedoes, the seventh tearing away her rudder. Oklahoma was hit by four torpedoes, the last two above her belt armor , which caused her to capsize. Maryland was hit by two of the converted 16" shells, but neither caused serious damage. Although the Japanese concentrated on battleships (the largest vessels present), they did not ignore other targets. The light cruiser Helena
26544-522: Was joined in the war against Japan by several of the Allied powers , including the British Empire and the Dutch government-in-exile , both of which had also been attacked by Japan. The Japanese made two attempts to continue their offensive and extend their outer defensive perimeter in the south and central Pacific to a point at which they could threaten Australia, Hawaii, and the U.S. west coast. The first offensive
26712-517: Was loaded onto slow transport ships for the rest of the trip to Guadalcanal. The damage done to Tanaka's convoy during the Battle of the Eastern Solomons caused the Japanese to reconsider trying to deliver more troops to Guadalcanal via slow transport. Instead, the ships carrying Kawaguchi's soldiers were rerouted to Rabaul. From there, the Japanese planned to deliver Kawaguchi's unit to Guadalcanal using fast-moving destroyers at night, staging through
26880-505: Was made by Japan, but this was not Admiral Yamamoto's intention. He originally stipulated that the attack should not commence until thirty minutes after Japan had informed the United States that peace negotiations were at an end. However, the attack began before the notice could be delivered. Tokyo transmitted the 5000-word notification (commonly called the "14-Part Message") in two blocks to the Japanese Embassy in Washington. Transcribing
27048-791: Was prepared to take opposing steps if "neighboring countries" were attacked. Japan and the United States engaged in negotiations during 1941, attempting to improve relations. In the course of these negotiations, Japan offered to withdraw from most of China and Indochina after making peace with the Nationalist government. It also proposed to adopt an independent interpretation of the Tripartite Pact and to refrain from trade discrimination, provided all other nations reciprocated. Washington rejected these proposals. Japanese Prime Minister Konoe then offered to meet with Roosevelt, but Roosevelt insisted on reaching an agreement before any meeting. The American ambassador to Japan repeatedly urged Roosevelt to accept
27216-422: Was selected as the headquarters and primary staging ground for the offensive, codenamed Operation Watchtower , with the commencement date set for 7 August. At first, only the seizure of Tulagi and the Santa Cruz Islands was planned, omitting a landing on Guadalcanal. After Allied reconnaissance discovered Japanese airfield construction efforts on Guadalcanal, its capture was added to the plan, and planned landings on
27384-438: Was sunk, and the older destroyer Mutsuki was so badly damaged that she had to be scuttled. Several other Japanese warships were damaged, including Tanaka's flagship Jintsū . At this point, Tanaka withdrew and rescheduled the supply run for the night of 28 August, to be carried out by the remaining destroyers. Japanese air raids against the Allied positions on Guadalcanal continued largely unabated during this time. On 25 August,
27552-676: Was tasked to attack Kāneʻohe, the rest Pearl Harbor proper. The separate sections arrived at the attack point almost simultaneously from several directions. Ninety minutes after it began, the attack was over. 2,008 sailors were killed and 710 others wounded; 218 soldiers and airmen (who were part of the Army prior to the independent United States Air Force in 1947) were killed and 364 wounded; 109 Marines were killed and 69 wounded; and 68 civilians were killed and 35 wounded. In total, 2,403 Americans were killed, and 1,178 were wounded. Eighteen ships were sunk or run aground, including five battleships. All of
27720-529: Was the first major land offensive by Allied forces against the Empire of Japan . On 7 August 1942, Allied forces, predominantly United States Marines , landed on Guadalcanal, Tulagi , and Florida Island in the southern Solomon Islands , with the objective of using Guadalcanal and Tulagi as bases in supporting a campaign to eventually capture or neutralize the major Japanese base at Rabaul on New Britain . The Japanese defenders, who had occupied those islands since May 1942, were outnumbered and overwhelmed by
27888-506: Was the only battleship that day to suffer catastrophic damage to her belt armor at the waterline from a torpedo. Admiral Chester Nimitz, in a report to Congress, confirmed that one midget submarine's torpedo (possibly from the other midget submarine that fired torpedoes but failed to hit a target) which was fired but did not explode was recovered in Pearl Harbor and was much larger than the aerial torpedoes. Others dispute this theory. The attack took place before any formal declaration of war
28056-407: Was thwarted in the naval Battle of the Coral Sea , which was a tactical stalemate but a strategic Allied victory in retrospect. It was the Allies' first major victory against the Japanese and significantly reduced the offensive capability of Japan's carrier forces. However, the battle did not temper Japan's audacious offensive military posture for several crucial months, with Japanese forces attempting
28224-438: Was torpedoed, and the concussion from the blast capsized the neighboring minelayer Oglala . Two destroyers in dry dock , Cassin and Downes , were destroyed when bombs penetrated their fuel bunkers . The leaking fuel caught fire; flooding the dry dock in an effort to fight fire made the burning oil rise, and both were burned out. Cassin slipped from her keel blocks and rolled against Downes . The light cruiser Raleigh
