 in 1937. In 1940, Japan invaded French Indochina in both an effort to control supplies reaching China, and as a first step to improve her access to resources in Southeast Asia. This move prompted an American embargo on oil exports to Japan, which in turn caused the Japanese to initiate their planned takeover of oil production in the Dutch East Indies. Furthermore, the transfer of the U.S. Pacific Fleet from its previous base in San Diego to its new base in Pearl Harbor was seen by the Japanese military as the U.S. readying itself for a potential conflict between the two countries.

Preliminary planning for an attack on Pearl Harbor to protect the move into the "Southern Resource Area" (the Japanese term for the East Indies and Southeast Asia generally) had begun in very early 1941, under the auspices of Admiral Yamamoto, then commanding Japan's Combined Fleet

By late 1941 U.S. Pacific bases and facilities had been placed on alert on multiple occasions, with hostilities between the U.S. and Japan expected by many observers. U.S. officials doubted Pearl Harbor would be the first target in any war with Japan, instead expecting the Philippines to be attacked first due to the threat it posed to sea lanes to the south and the erroneous belief that Japan was not capable of mounting more than one major naval operation at a time.

Objectives

The attack had several major aims. First, it was supposed to destroy American fleet units, thereby preventing the Pacific Fleet from interfering with Japanese conquest of the Dutch East Indies. Second, it was a means to buy time for Japan to consolidate her position and increase her naval strength, before the shipbuilding of the Vinson-Walsh Act

 erased any chance of victory. Finally, it was intended as a blow against American morale, which might discourage further fighting and enable Japan to conquer Southeast Asia without interference.

Making battleships the main target was a means of striking at morale, since they were the prestige ships of any navy at the time. Because both Japanese and American strategic thinking and doctrine was derived from the work of Captain Alfred Mahan

, which held battleships were decisive in naval warfare, it was also a means of striking at the fighting power of the Pacific Fleet; if it succeeded, it meant the ultimate Pacific battle ("decisive battle", in Japanese Navy thinking), which would inevitably be fought by battleships, would be postponed, if not prevented entirely. With that in mind, Yamamoto intended the Pacific Fleet should be sought and attacked "wherever it might be found in the Pacific". A 14 November 1941 tabletop exercise suggested alert defenders could sink two carriers and damage two more, even with providential weather, which amounted to all the strength Naval General Staff had wanted to allocate to the operation. Nevertheless, Yamamoto pressed ahead.

Japanese confidence in their ability to achieve a short, victorious war also meant other targets in the harbor, especially the Navy Yard, oil tank farms, and Submarine Base, could safely be ignored, since the war would be over before the influence of these facilities would be felt.

Approach and attack


Pearlharborcarrierchart
On November 26, 1941, a Japanese task force (the Kido Butai, or Striking Force) of six aircraft carriers departed northern Japan en route to a position to northwest of Hawaii, intending to launch its aircraft to attack Pearl Harbor. In all, 405 aircraft were intended to be used: 360 for the two attack waves, 48 on defensive combat air patrol

s were to attack ground targets. Fighters were ordered to strafe and destroy as many parked aircraft as possible to ensure they did not get into the air to counterattack the bombers, especially in the first wave. When the fighters' fuel got low they were to refuel at the aircraft carriers and return to combat. Fighters were to serve CAP duties where needed, especially over US airfields.

Before the attack commenced, two reconnaissance aircraft launched from cruisers were sent to scout over Oahu and report on enemy fleet composition and location. Another four scout planes patrolled the area between the Kido Butai and Niihau

Japanese declaration of war

While the attack ultimately took place before a formal declaration of war by Japan, Admiral Yamamoto originally stipulated the attack should not commence until thirty minutes after Japan had informed the United States she considered the peace negotiations at an end. In this way, the Japanese tried both to uphold the conventions of war as well as achieving surprise. Despite these intentions, the attack had already begun when the 5,000-word notification was delivered. Tokyo transmitted the message to the Japanese embassy (in two blocks), which ultimately took too long transcribing the message to deliver it in time, while U.S. codebreakers had already deciphered and translated most of it hours before the Japanese embassy was scheduled to deliver it. While sometimes described as a declaration of war, "this dispatch neither declared war nor severed diplomatic relations". The declaration of war was printed in the front page of Japanese newspapers in the evening edition on December 8.

Although the operators reported a target echo larger than anything they had ever seen, an untrained officer at the new and only partially activated Intercept Center, Lieutenant Kermit A. Tyler, presumed the scheduled arrival of six B-17 bombers was the source. The direction from which the aircraft were coming was close (only a few degrees separated the two inbound courses), while the operators had never seen a formation as large on radar; they neglected to tell Tyler of its size, while Tyler, for security reasons, could not tell them the B-17s were due (even though it was widely known).

Several U.S. aircraft were shot down as the first wave approached land, and one at least radioed a somewhat incoherent warning. Other warnings from ships off the harbor entrance were still being processed or awaiting confirmation when the attacking planes began bombing and strafing. Nevertheless it is not clear any warnings would have had much effect even if they had been interpreted correctly and much more promptly. The results the Japanese achieved in the Philippines

The air portion of the attack on Pearl Harbor began at 7:48 a.m. Hawaiian Time (3:18 a.m. December 8 Japanese Standard Time, as kept by ships of the Kido Butai), with the attack on Kaneohe. A total of 353 Japanese planes in two waves reached Oahu. Slow, vulnerable torpedo bombers led the first wave, exploiting the first moments of surprise to attack the most important ships present (the battleships), while dive bombers attacked U.S. air bases across Oahu, starting with Hickam Field, the largest, and Wheeler Field, the main U.S. Army Air Force fighter base.

Men aboard U.S. ships awoke to the sounds of alarms, bombs exploding, and gunfire prompting bleary eyed men into dressing 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.) The defenders were very unprepared. Ammunition lockers were locked, aircraft parked wingtip to wingtip in the open to deter sabotage, guns unmanned (none of the Navy's 5"/38s and only a quarter of its machine guns, and only four of 31 Army batteries got in action). Despite this and low alert status, many American military personnel responded effectively during the battle. Ensign Joe Taussig got his ship, USS Nevada

. Four planes failed to launch because of technical difficulties. This wave and its targets comprised:
  • 1st Group — 54 B5Ns armed with and general purpose bombs
    • 27 B5Ns — aircraft and hangars on Kaneohe, Ford Island, and Barbers Point
    • 27 B5N — hangars and aircraft on Hickam Field
  • 2nd Group (targets: aircraft carriers and cruisers)
    • 81 D3As armed with general purpose bombs, in four sections
  • 3rd Group — (targets: aircraft at Ford Island, Hickham Field, Wheeler Field, Barber’s Point, Kaneohe)
    • 36 A6Ms for defense and strafing
The second wave was divided into three groups. One was tasked to attack Kaneohe, 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. 2,386 Americans died (55 were civilians, most killed by unexploded American anti-aircraft shells landing in civilian areas), a further 1,139 wounded. Eighteen ships were sunk, including five battleships.

Of the American fatalities, nearly half of the total were due to the explosion of USS Arizona

, the chief architect of the attack, urged Nagumo to carry out a third strike in order to destroy as much of Pearl Harbor's fuel and torpedo storage, maintenance, and dry dock facilities as possible. Military historians have suggested the destruction of these would have hampered the U.S. Pacific Fleet far more seriously than loss of its battleships. If they had been wiped out, "serious [American] operations in the Pacific would have been postponed for more than a year." Nagumo, however, decided to withdraw for several reasons:

  • American anti-aircraft performance had improved considerably during the second strike, and two thirds of Japan's losses were incurred during the second wave. Nagumo felt if he launched a third strike, he would be risking three quarters of the Combined Fleet's strength to wipe out the remaining targets (which included the facilities) while suffering higher aircraft losses.
  • The location of the American carriers remained unknown. In addition, the Admiral was concerned his force was now within range of American land-based bombers. Nagumo was uncertain whether the U.S. had enough surviving planes remaining on Hawaii to launch an attack against his carriers.
  • A third wave would have required substantial preparation and turnaround time, and would have meant returning planes would have had to land at night. At the time, no navy had developed night carrier techniques, so this was a substantial risk.
  • The task force's fuel situation did not permit him to remain in waters north of Pearl Harbor much longer, since he was at the very limits of logistical support. To do so risked running unacceptably low on fuel, perhaps even having to abandon destroyers en route home.
  • He believed the second strike had essentially satisfied the main objective of his mission — the neutralization of the Pacific Fleet — and did not wish to risk further losses. Moreover, it was Japanese Navy practice to prefer the conservation of strength over the total destruction of the enemy.


At a conference aboard Yamato the following morning, Yamamoto initially supported Nagumo. In retrospect, sparing the vital dockyards, maintenance shops, and oil depots meant the U.S. could respond relatively quickly to Japanese activities in the Pacific. Yamamoto later regretted Nagumo's decision to withdraw and categorically stated it had been a great mistake not to order a third strike.

Vice Admiral Homer Norman Wallin was a Vice admiral in the United States Navy, best known for his salvage of ships sunk in the attack on Pearl Harbor....
, Material Officer for Commander, Battle Force, U.S. Pacific Fleet, was immediately retained to lead salvage operations.

Around Pearl Harbor, divers from the Navy (shore and tenders), the Naval Shipyard, and civilian contractors (Pacific Bridge and others) began work on the ships which could be refloated. They patched holes, cleared debris, and pumped water out of ships. Navy divers worked inside the damaged ships. Within six months, five battleships and two cruisers were patched or refloated so they could be sent to shipyards in Pearl and on the mainland for extensive repair.

Intensive salvage operations continued for another year, a total of some 20,000 hours under water. Oklahoma, while successfully raised, was never repaired. Arizona and the target ship Utah were too heavily damaged for salvage, though much of their armament and equipment was removed and put to use aboard other vessels. Today, the two hulks remain where they were sunk, with Arizona becoming a war memorial

Aftermath


In the wake of the attack, 16 Congressional Medals of Honor, 51 Navy Crosses, 53 Silver Crosses, four Navy and Marine Corps Medals, one Distinguished Flying Cross, four Distinguished Service Crosses, one Distinguished Service Medal, and three Bronze Stars were awarded to the American servicemen who distinguished themselves in combat at Pearl Harbor.

Though the attack inflicted large-scale destruction on US vessels and aircraft, it did not affect Pearl Harbor's fuel storage, maintenance, and intelligence facilities.

 later to recollect "In all the war I never received a more direct shock. As I turned and twisted in bed the full horror of the news sank in upon me. There were no British or American capital ships in the Indian Ocean or the Pacific except the American survivors of Pearl Harbor who were hastening back to California. Over this vast expanse of waters Japan was supreme and we everywhere were weak and naked".

Fortunately for the United States, the American aircraft carriers were untouched by the Japanese attack, otherwise the Pacific Fleet's ability to conduct offensive operations would have been crippled for a year or so (given no diversions from the Atlantic Fleet). As it was, the elimination of the battleships left the U.S. Navy with no choice but rely on its aircraft carriers and submarines — the very weapons with which the U.S. Navy halted and eventually reversed the Japanese advance. Five of the eight battleships were repaired and returned to service, but their slow speed limited their deployment, serving mainly in shore bombardment roles. A major flaw of Japanese strategic thinking was a belief the ultimate Pacific battle would be fought by battleships, in keeping with the doctrine of Captain Alfred Mahan. As a result, Yamamoto (and his successors) hoarded battleships for a "decisive battle" that never happened.

Ultimately, targets not on Genda's list, such as the submarine base and the old headquarters building, proved more important than any battleship. It was submarines that immobilized the Imperial Japanese Navy's heavy ships and brought Japan's economy to a standstill by crippling the transportation of oil and raw materials.
