  1. PEARL HARBOR THE DAY OF INFAMY December 7, 1941

  2. Sequence of Events • Saturday, December 6 - Washington D.C. - U.S. President Franklin Roosevelt makes a final appeal to the Emperor of Japan for peace. There is no reply. Late this same day, the U.S. code-breaking service begins intercepting a 14-part Japanese message and deciphers the first 13 parts, passing them on to the President and Secretary of State. The Americans believe a Japanese attack is imminent, most likely somewhere in Southeast Asia.

  3. Sequence of Events • Sunday, December 7 - Washington D.C. - The last part of the Japanese message, stating that diplomatic relations with the U.S. are to be broken off, reaches Washington in the morning and is decoded at approximately 9 a.m. About an hour later, another Japanese message is intercepted. It instructs the Japanese embassy to deliver the main message to the Americans at 1 p.m. The Americans realize this time corresponds with early morning time in Pearl Harbor, which is several hours behind. The U.S. War Department then sends out an alert but uses a commercial telegraph because radio contact with Hawaii is temporarily broken. Delays prevent the alert from arriving at headquarters in Oahu until noontime (Hawaii time) four hours after the attack has already begun.

  4. Sequence of Events • Sunday, December 7 - Islands of Hawaii, near Oahu - The Japanese attack force under the command of Admiral Nagumo, consisting of six carriers with 423 planes, is about to attack. At 6 a.m., the first attack wave of 183 Japanese planes takes off from the carriers located 230 miles north of Oahu and heads for the U.S. Pacific Fleet at Pearl Harbor. • Pearl Harbor - At 7:02 a.m., two Army operators at Oahu's northern shore radar station detect the Japanese air attack approaching and contact a junior officer who disregards their reports, thinking they are American B-17 planes which are expected in from the U.S. west coast.

  5. Sequence of Events • Near Oahu - At 7:15 a.m., a second attack wave of 167 planes takes off from the Japanese carriers and heads for Pearl Harbor. • Pearl Harbor is not on a state on high alert. Senior commanders have concluded, based on available intelligence, there is no reason to believe an attack is imminent. Aircraft are therefore left parked wingtip to wingtip on airfields, anti-aircraft guns are unmanned with many ammunition boxes kept locked in accordance with peacetime regulations. There are also no torpedo nets protecting the fleet anchorage. And since it is Sunday morning, many officers and crewmen are leisurely ashore.

  6. Sequence of Events • At 7:53 a.m., the first Japanese assault wave, with 51 'Val' dive bombers, 40 'Kate' torpedo bombers, 50 high level bombers and 43 'Zero' fighters, commences the attack with flight commander, Mitsuo Fuchida, sounding the battle cry: "Tora! Tora! Tora!" (Tiger! Tiger! Tiger!). • The Americans are taken completely by surprise. The first attack wave targets airfields and battleships. The second wave targets other ships and shipyard facilities. The air raid lasts until 9:45 a.m. Eight battleships are damaged, with five sunk. Three light cruisers, three destroyers and three smaller vessels are lost along with 188 aircraft. The Japanese lose 27 planes and five midget submarines which attempted to penetrate the inner harbor and launch torpedoes.

  7. Sequence of Events • Escaping damage from the attack are the prime targets, the three U.S. Pacific Fleet aircraft carriers, Lexington, Enterprise and Saratoga, which were not in the port. Also escaping damage are the base fuel tanks. • The casualty list includes 2,335 servicemen and 68 civilians killed, with 1,178 wounded. Included are 1,104 men aboard the Battleship USS Arizona killed after a 1,760-pound air bomb penetrated into the forward magazine causing catastrophic explosions.

  8. Sequence of Events • In Washington, various delays prevent the Japanese diplomats from presenting their war message to Secretary of State, Cordell Hull, until 2:30 p.m. (Washington time) just as the first reports of the air raid at Pearl Harbor are being read by Hull. • News of the "sneak attack" is broadcast to the American public via radio bulletins, with many popular Sunday afternoon entertainment programs being interrupted. The news sends a shockwave across the nation and results in a tremendous influx of young volunteers into the U.S. armed forces. The attack also unites the nation behind the President and effectively ends isolationist sentiment in the country. • Monday, December 8 - The United States and Britain declare war on Japan with President Roosevelt calling December 7, "a date which will live in infamy..."

  9. Sequence of Events • Thursday, December 11 - Germany and Italy declare war on the United States. The European and Southeast Asian wars have now become a global conflict with the Axis powers; Japan, Germany and Italy, united against America, Britain, France, and their Allies. • Wednesday, December 17 - Admiral Chester W. Nimitz becomes the new commander of the U.S. Pacific Fleet. • Both senior commanders at Pearl Harbor; Navy Admiral Husband E. Kimmel, and Army Lt. General Walter C. Short, were relieved of their duties following the attack. Subsequent investigations will fault the men for failing to adopt adequate defense measures.

  10. USS Arizona

  11. Causes… • The U.S. demanded that Japan withdraw from China and Indochina • Japan thought that attacking the U.S. would provide them an easy win, and a territory with abundant land and resources to rule once they were victorious. • The U.S. oil embargo against Japan was hurting Japan’s economy

  12. USS Arizona

  13. Major Combatants Japan • Fleet of 6 Aircraft Carriers under the command of Admiral Nagumo and Admiral Yamamoto • Aerial Assault Force under the command of Mitsuo Fuchida United States - Pearl Harbor Naval/Army Base under the command of Admiral Husband E. Kimmel and Lt. General Walter C. Short

  14. Battle Sequence • 5 PHASE ATTACK BY JAPANESE… (as noted by the U.S. Navy) • PHASE 1: Combined torpedo plane and dive bomber attacks lasting from 7:55 a.m. to 8:25 a.m. • PHASE 2: Lull in attacks lasting from 8:25 - 8:40 a.m. • PHASE 3: Horizontal bomber attacks from 8:40 – 9:15 a.m. • PHASE 4: Dive bomber attacks between 9:15-9:45 a.m. • PHASE 5: Warning of attacks and completion of raid after 9:45 a.m.

  15. Eyewitness Account • Commander Mitsuo Fuchida • “Veering right toward the west coast of the island, we could see that the sky over Pearl Harbor was clear. Presently the harbor itself bacame visible across the central Oahu plain, a film of morning mist hovering over it. I peered intently through my binoculars at the ships riding peacefully at anchor. One by one I counted them. Yes, the battleships were there all right, eight of them! But our last lingering hope of finding any carriers prestent was now gone. Not one was to be seen.”

  16. Warfare Used During Attack • Japan • 81 Fighter Planes • 135 Dive Bombers • 104 Horizontal Bombers • 40 Torpedo Planes • At least 5 Midget Submarines

  17. Warfare (continued) • United States • 108 Fighter Planes (59 not available for flight) • 35 Army Bombers (27 not available for flight) • 993 Army/Navy Antiaircraft Guns

  18. Casualties Japan • Less then 100 men • 29 planes • 5 midget submarines United States • 2,335 servicemen killed, 68 civilians killed, 1,178 wounded • 188 planes • 18 ships (8 battleships, 3 light cruisers, 3 destroyers, 4 other vessels)

  19. USS Arizona Burning: 1,100+ servicemen died on the ship

  20. Eyewitness Account • Marine Corporal E.C. Nightingale • “I was about three quarters of the way to the first platform on the mast when it seemed as though a bomb struck our quarterdeck. I could hear shrapnel or fragments whistling past me. As soon as I reached the first platform, I saw Second Lieutenant Simonson lying on his back with blood on his shirt front. I bent over him…He was dead…”

  21. Eyewitness Account • Lt. Ruth Erickson, USN (Nurse) • “The first patient came into our dressing room at 8:25 a.m. with a large opening in his abdomen and bleeding profusely. They started an intravenous and transfusion. I can still see the tremor of Dr. Brunson’s hand as he picked up the needle. Everyone was terrified. The patient died within the hour.”

  22. Effects/Outcome • Japan dealt a seemingly crippling blow to the U.S. Pacific fleet (U.S. Pacific Fleet aircraft carriers: Lexington, Enterprise, & Saratoga were not in port) • Japan began their quest for a Pacific empire • The U.S. finally was forced to join World War II (“The Sleeping Giant was awakened”) • The U.S. & Great Britain declare war on Japan (Dec. 8, 1941) • Germany & Italy declare war on the U.S. (Dec. 11, 1941)
