On Sunday morning, December 7, 1941 a surprise, preemptive military strike by the Imperial Japanese Navy Air Service upon the United States (a neutral country at the time) against the naval base at Pearl Harbor in Honolulu, Territory of Hawaii. The attack led to the United States' formal entry into World War II the next day.
These pictures will give you an idea about it.
The Japanese attack had several major aims. First, it intended to destroy important American fleet units, thereby preventing the Pacific Fleet from interfering with Japanese conquest of the Dutch East Indies and Malaya and to enable Japan to conquer Southeast Asia without interference.
Second, it was hoped to buy time for Japan to consolidate its position and increase its naval strength before shipbuilding authorized by the 1940 Vinson-Walsh Act erased any chance of victory. Third, to deliver a blow to America's ability to mobilize its forces in the Pacific, battleships were chosen as the main targets, since they were the prestige ships of any navy at the time.
Finally, it was hoped that the attack would undermine American morale such that the U.S. government would drop its demands contrary to Japanese interests, and would seek a compromise peace with Japan.
Preliminary planning for an attack on Pearl Harbor to protect the move into the "Southern Resource Area" (the Japanese term for the Dutch East Indies and Southeast Asia generally) had begun very early in 1941 under the auspices of Admiral Isoroku Yamamoto, then commanding Japan's Combined Fleet.
Yamamoto 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 Captain Minoru Genda and Yamamoto's Deputy Chief of Staff, Captain Kameto Kuroshima. The planners studied the 1940 British air attack on the Italian fleet at Taranto intensively.
a Japanese task force (the Striking Force) of six aircraft carriers—Akagi, Kaga, Sōryū, Hiryū, Shōkaku, and Zuikaku was 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 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 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 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 get into the air to intercept 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 U.S. airfields.
Several Japanese junior officers including Fuchida and Genda urged commander of the Kido Butai, Chūichi 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.
Genda, who had unsuccessfully advocated for invading Hawaii after the air attack, believed that without an invasion, three strikes were necessary to disable the base as much as possible. The captains of the other five carriers in the task force reported they were willing and ready to carry out a third strike.
Nagumo, however, decided to withdraw as he noticed that the American anti-aircraft performance had improved considerably during the second strike, and two thirds of Japan's losses were incurred during the second wave. Beside 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, only the British Royal Navy had developed night carrier techniques, so this was a substantial risk.
None to say, 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 limit of logistical support. To do so risked running unacceptably low on fuel, perhaps even having to abandon destroyers en route home.
However, at a conference aboard his flagship the following morning, Yamamoto supported Nagumo's withdrawal without launching a third wave. In retrospect, sparing the vital dockyards, maintenance shops, and the oil tank farm 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.
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 1,143 were wounded. Eighteen ships were sunk or run aground, including five battleships. All of the Americans killed or wounded during the attack were non-combatants, given the fact there was no state of war when the attack occurred.
Although the Japanese concentrated on battleships (the largest vessels present), they did not ignore other targets. The light cruiser Helena 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 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 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 Lt. Lewis M. Sanders, 2nd Lt. Philip M. Rasmussen, 2nd Lt. Kenneth M. Taylor, 2nd Lt. George S. Welch, 2nd Lt. Harry W. Brown, and 2nd Lt. Gordon H. Sterling Jr. Of 33 PBYs in Hawaii, 24 were destroyed, six damaged beyond repair, and three on patrol at the time of the attack returned undamaged.
Friendly fire brought down some U.S. planes on top of that, including five from an inbound flight from Enterprise.
At the time of the attack, nine civilian aircraft were flying in the vicinity of Pearl Harbor. Of these, three were shot down
Fifty-five Japanese airmen and nine submariners were killed in the attack, and one, Kazuo Sakamaki, was captured. Of Japan's 414 available planes, 350 took part in the raid in which 29 were lost; nine in the first wave (three fighters, one dive bomber and five torpedo bombers) and 20 in the second wave (six fighters and 14 dive bombers). with another 74 damaged by antiaircraft fire from the ground.
Ever since the Japanese attack, there has been debate as to how and why the United States had been caught unaware, and how much and when American officials knew of Japanese plans and related topics.
As early as 1924, Chief of U.S. Air Service Mason Patrick displayed a concern for military vulnerabilities in the Pacific, having sent Gen. Billy Mitchell on a survey of the Pacific and the East. Patrick called Mitchell's subsequent report, which identified vulnerabilities in Hawaii, a "theoretical treatise on employment of airpower in the Pacific, which, in all probability undoubtedly will be of extreme value some 10 or 15 years hence."
At least two naval war games, one in 1932 and another in 1936, proved that Pearl was vulnerable to such an attack. Admiral James Richardson was removed from command shortly after protesting President Roosevelt's decision to move the bulk of the Pacific fleet to Pearl Harbor.
The decisions of military and political leadership to ignore these warnings have contributed to conspiracy theories. Several writers, including decorated World War II veteran and journalist Robert Stinnett, author of Day of Deceit, and former United States Rear Admiral Robert Alfred Theobald, author of The Final Secret of Pearl Harbor: The Washington Background of the Pearl Harbor Attack, have argued that various parties high in the U.S. and British governments knew of the attack in advance and may even have let it happen or encouraged it in order to force the U.S. into war via the so-called "back door". However, this conspiracy theory is rejected by mainstream historians.
Striking the Pacific Fleet at anchor in Pearl Harbor carried 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—this of timing, and known to the Japanese was the absence from Pearl Harbor of all three of the U.S. Pacific Fleet's aircraft carriers (Enterprise, Lexington, and Saratoga). IJN top command was attached to Admiral Mahan's "decisive battle" doctrine, especially that of destroying the maximum number of battleships. Despite these concerns, Yamamoto decided to press 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, were ignored, since—by their thinking—the war would be over before the influence of these facilities would be felt.
