Under Admiral Yamomato, the Japanese Navy delivered a stunning blow to the United States. The brilliant, two wave attack, utterly surprised the Americans. Over 2,000 American sailors were killed in this onslaught, as well as 109 marines, and 218 soldiers 1. By looking at what Japan did preceding the attack one can see how the American troops should have been better prepared for such an attack. The Japanese started their military increase in 1937, when Emperor Hirohito reigned, and they took over China 2. Their increase continued in 1939, when they tuned South to take over Hainan on February 10. Gordon Prange states a reason for Japan conquering small areas as well: "In March of the same year Japan laid claim to the Spratlys-coral islands offering potential havens for planes and small naval craft, located on a beautiful navigational fix between Saigon and North Borneo, Manila, and Singapore 3." When France fell in 1940, Japan put troops in Northern French Indochina, this was their stepping stone to further advancement southward. In 1941, Japan got ready to expand into Southeast Asia. These areas included Malaya, the Philippines, the Netherlands, and the East 4. "The United States had to consider Japan in the context of its Axis Alliance, for aid and concessions to Tokyo in effect, meant aid and concessions for Berlin and Rome .5" Japan had a long list of grievances against the United States, the foremost being the recognition of the Chiang Kai-Shek regime and the nonrecognition of Manchuko.6 The U.S. Military in Asia was a constant annoyance to Japan. They felt that all Allied forces in Asia must be removed.7 By the beginning of July 1940, Washington placed all exports on aviation fuel and high-grade scrap iron and steel under license and control of the Federal Government. In September 1940 after Japanese forces moved into northern Indochina, Roosevelt finally announced an embargo on scrap iron and steel to Japan. Japanese anger focused on the embargoes which the U.S. had placed on American exports to Japan. By the end of 1940 Washington had cut off all war supplies except petroleum.8 Japan thought that the U.S. Navy was directed at them. The U.S. had stationed a large fleet in Pearl Harbor in the Spring of 1940. The nation who Commodore Matthew Perry had opened to the modern world now stood face-to-face with the U.S. The Japanese called this Taiheiyo-no-gan or Cancer of the Pacific.9 On November 27, the Commander of the Coast Guard at Honolulu was put on war warning. He was to put vessels in water to run up and down and listen for submarines. In Japan, Admiral Isoroku Yamamoto, Commander of the Japanese Combined Fleet, was trying to come up with a way to launch a surprise attack on the American fleet. He ordered Admiral Onishi to start studying a way to launch the assault.10 Onishi had called in Commander Minoru Genda , a crack airman, and ten days later he had a plan. It consisted of their fleet attacking the U.S. Pacific Fleet at Pearl Harbor. This seemed to be an enormous task, considering that Japan was thousands of miles away from Hawaii. Many problems arose, especially about the shallow depth of Pearl Harbor. At its deepest points it was only about forty feet deep. Commander Genda, worked wonders with this problem.11 He experimented on the Inland Sea, setting up short torpedo runs. Genda eventually modified the torpedo by attaching fins to it. Everything was done in top secrecy.12 Finally, Admiral Onishi and 13 other officers were called to Tokyo to be given the word. Lord states, "Then from September 2 to 13, they all tested the idea on the game board at the Naval War College".13 On September 13, the rough draft for Pearl Harbor was issued. Next, came the training stage. Men were selected for key jobs. Commander Mitsuo Fuchida was transferred to the carrier Akagi, and named commander of all air groups in The First Air Fleet. A few problems remained. For instance the torpedoes were still having trouble and getting stuck in the mud. Commander Genda finally came up with the solution of putting wooden stabilizers on them to keep them from hitting the shallow bottom of Pearl Harbor .14 In addition, information showed how battleships were paired together and torpedoes wouldn't be able to reach the inner ship. So ordinance men fit 15-inch and 16-inch armor piercing shells with fins to penetrate the thick armor-plated decks of the ships.15 Instead of taking the normal route to Hawaii, they would go far north. They crossed over between Midway and the Aleutian Islands, then cutting south to Hawaii. This was done in order to avoid commercial traffic. Suguru Suzuki went this route on the Taiyo Maru. He went to check vital information for Japan. He concluded many things from this trip. First, being that they would have to refuel along the way. Second, it was possible to launch survey planes from a secure position. On his voyage he didn't encounter a single ship.16 While in Hawaii, he gained information about Hickman Air Field. He also obtained aerial shots of Pearl Harbor taken on October 21. He gained these from a private plane for visitors. Tourists were not prohibited from taking them. When he returned to Tokyo, he compared notes with Lieutenant Commander Toshihide Maejima, who was also on board. In Tokyo, on November 7, Yamamoto set the date of December 8 for the attack. This was December 7 Hawaiian time. This was done because of favorable moonlight and the best chance to catch men off duty and ships in port. The rendezvous point for the Striking Force was in cold Tankan Bay. On November 21, the last ship arrived. There were now 33 ships in all.17 With Admiral Nagumo was aboard the Akagi. On the 25th, Yamamoto ordered the fleet to get going the following day. The fleet was very tedious about leaving no traces of any thing behind, so they burned their garbage. The fleet also suffered other drawbacks, like when the Akagi's propeller became entangled with a cable. The weather had also become a factor, because of the harsh seas, steady gales of wind, and thick fog. Lord also tells us that formation had become a problem because of all the ships traveling at different speeds.18 The fleet first tried refueling on the 28th. This turned out to be dangerous work as they lost several men during the ordeal. The men eventually became better at this. However, the men had to worry about the weather, which was getting worse. The oil drums now spilled and fell over due to the wind. At this time all the ships were changed to winter oil and used the highest grade fuel to keep the smoke at a minimum.19 Messages from Japan began to flow in about what ships were now in the harbor. On December 3rd in Pearl Harbor, they found out that there were 2 battleships, 1 carrier, 2 Class-A cruisers, and 12 destroyers departed. 5 battleships, 3 Class-A cruisers 3 Class-B cruisers, 12 destroyers, and 1 seaplane aircraft carrier entered.20 On the 5th the fleet refueled most of the day and night. Then, on the 6th Kusaka refueled the remainder of the task force. He wanted to have the tanks as full as possible for the morning of the attack. By late morning the task was accomplished, and the tankers withdrew.21 The fleet was now 640 miles due north of Oahu. With the slow tankers now gone, the remainder could surge ahead. Shortly before noon, Kusaka was ready to go full speed ahead. Late on the night of the 6th, they received word that intelligence could detect no Sea or Land alerts. There were no barrage balloons sighted by the scouting subs either. At 1:20 A.M. the last message came saying: December 6 (local time) Vessels moored in Harbor: 9 Battleships; 3 Class-B Cruisers; 3 Seaplane tenders; 17 Destroyers. Entering Harbor are 4 Class-B Cruisers; 3 Destroyers. All Aircraft Carriers and Heavy Cruisers have departed Harbor . . . No indication of any changes in U.S. Fleet or anything else unusual.22 The crews and pilots were now ready. The pilots had been training and studying for months. They learned the position of the ships and what they looked like by using scale models. They were drilled until they knew Pearl Harbor backward and forward.23 Admiral Nagumo planned to hit Pearl Harbor in two mighty waves with a total of 353 planes. The first was to go at 6:00 A.M. with 40 torpedo planes, 51 dive bombers, 49 horizontal bombers, and 43 fighters to provide cover. The second wave was set to go at 7:15 A.M. with 80 dive bombers, 54 high-level bombers, and 36 more fighters. This left 39 planes to guard the task force if the Americans struck back. All eight battleships were in port. Including the battleships there totaled 96 warships in Pearl Harbor on this Sunday Morning. At the airfields, General Short had lined the fighters in antisabotage formation. Earlier, he had receiving a message that there may be an attack coming. This made the planes easy targets for Fuchida's assault team.24 At 7:03, the Ward, a destroyer picked up a Japanese midget sub. The Ward opened fire on it. They unloaded five depth charges and watched as a huge bubble of oil rose.25 In the planes hurtled. Commander Takahashi's dive bombers went to the airfields. Murata's 40 torpedo planes started swinging into position to attack the big ships. Commander Fuchida marked time off Barbers point with the horizontal bombers. They were all about to attack together instead of in stages, but it did not matter now. A few minutes earlier Commander Fuchida had signaled TO . . . TO . . . TO . . . in Morse code aboard the command ship of the Pearl Harbor Striking Force.26 The "TO" signal meant charge. Four minutes later Fuchida's radioman, even before the fist bomb fell, used the 2nd signal TORA . . . TORA . . . TORA . . ., which meant "We have succeeded in Surprise attack".27 At 7:55 A.M. the dive bombers had begun the attack on Ford island and the air bases.28 At 7:56 A.M. an ensign aboard the Raleigh saw the torpedo planes flying in low. The ensign believed that they were Marine planes flying maneuvers, so he called out anti aircraft crews to practice with them. Suddenly torpedoes rocketed into the Raleigh herself. The close by Detroit got off unharmed, but the Utah shuddered under two blows. Several seaman still thought that it was the Army doing this. A fifth Japanese plane in that group let fly at the Oglala and Helena. The torpedo completely missed the Oglala and crushed the Helena.29 A 23 piece band waited until 8:00 to play morning colors.30 It was now 7:58 and the planes started to take position. Lord tells how the attack started on Battleship row: The band crashed into "The Star Spangled Banner." A Japanese plane skimmed across the harbor . . . dropped a torpedo at the Arizona . . . and pealed off right over the Nevada's fantail. The rear gunner sprayed the men standing at attention, but he must have been a poor shoot. He missed the entire band and Marine guard, lined up in two rows. He did succeed in shredding the flag, which was just being raised.31 As soon as they finished playing they scattered for shelter. A PA system announced again and again that this wasn't a drill. Ship after ship began to catch on. The Oklahoma sounded its air raid siren. The Oklahoma took the first of five torpedoes aimed at it. The West Virginia took the first of six. Next, the Arizona got two , although slightly blocked by the Vestal, and the California received two. The only ships that seemed safe were the inside ships like the Maryland and Tennessee.32 The Oglala, which was affected by the blast from the Helena, was in shambles. Broken glass and china littered the deck. The Oklahoma was worst of all. The second torpedo to hit her put her lights out. The next three to hit ripped her side open. The sea rushed in and swept through her.33 Most ships never carried out their morning colors. At 7:58 Washington already knew that Pearl Harbor was being attacked. The Airfields were being destroyed. Flames were billowing from Wheeler. The dive bombers crushed the planes lined up in anti-sabotage formation. Zeroes were barreling over the Wainane Mountains and were shooting up the base. By 8:05, 33 of the 49 planes at Kaneohe were already blazing. Crews aboard the ships tried to fire back at the Japanese attackers. They used machine guns and the anti-aircraft crews got some shots off. As planes flew about the Nevada again machine guns kept them away. The Arizona had no protection except the tiny Vestal , which was moored beside it. Nothing could stop the steel pouring down from Fuchida's horizontal bombers. A large bomb fell in-between No.4 and No.6 guns. Another hit the number 4 turret.34 The West Virginia was taking a terrible beating. A Japanese torpedo plane headed for the casemate, and it landed just underneath. More and more torpedoes continued to come. The ship slowly swung back to starboard after rigorous counterflooding.35 Suddenly the Arizona blew up. The boiler and magazine blew under direct hits. Over 1,000 men were killed in the explosion. The second bomb in her went down her chimney stack.36 The Maryland, moored inside the Oklahoma, was safe from torpedoes and only caught two bombs. The Tennessee had more trouble, as one of the converted 16-inch shells fell on her number 2 turret. Splinters from the Tennessee ripped apart more of the West Virginia. The Arizona, Oklahoma and West Virginia were sunk. The California was sinking and the Tennessee and Maryland were bottled up by the wrecked ships along side them. The Pennsylvania was squatting in dry-dock. Only the Nevada was left. She seemed hopeless with one torpedo and two bombs in her already. The Raleigh was sagging heavily to port. The San Francisco and the St. Louis were on limited availability because of repairs. There were many ships in Drydock that waited for bombs to hit them. As Fuchida's first wave ended at about 8:30, he was pleased. The second wave commenced 95 minutes after the first. This wave completed most of the job.37 There was more resistance this time as the American's had more time to get ready. The second wave had a harder task. Gun crews were able to assemble, and shoot down Japanese planes.38 Crews aboard all types of ships winged enemy planes. The Nevada got up enough steam in 45 minutes to head out of the channel. All Japanese aircraft converged on the ship. They dropped bombs on the Pennsylvania, which was sitting in dry dock.39 The Americans lost five battleship, 4 other warships, almost 200 aircraft, and over 2,400 lives of American men and women in over two hours. This is even more staggering when one totals the Japanese loses at only 29 aircraft and 55 men.40 Some say that Pearl Harbor could have been avoided. If the crews had paid more attention to warnings and radar. Commander Arthur Davis told Admiral Kimmel that if long searches had taken place they might have detected the Japanese and been ready for them.41 If they had spotted them, the results may have been vastly different. The Japanese fleet utterly crushed the Pacific Fleet. We now see how the Japanese kept their secret away from the Americans. The way that they kept their plan and training secret, was truly phenomenal. They planned their assault with care and discipline. The Japanese took great pride in executing their plan as best as they possibly could. The participants worked and trained for the chance to take part in their country's great assault. This bombardment hindered the American efforts in a quite substantial way. If the American Carriers had been in port that day, like the Japanese had hoped the result could have been even more devastating.
