Its annoying me enough to post this at 1am To set the scene: On the day the Japanese fleet set out for amongst other locations Pearl Harbour in the Hawaian Islands the Americans had yet again asked the Japanese to completely withdraw from China. So with this in mind and given that the Japanese were clearly not budging you would expect that the Americans would be on full alert on suspicion of any reaction other than compliance to withdraw. As I understand it a sizeable fleet out of pearl harbour were on training that week but returned to pearl harbour at the weekend. The Japanese fleet left for pearl harbour on scrict radio silence to prevent detection, clearly the Americans knew the fleet was on the move but did not make any attempt to identify there whereabouts, or did they? Once in position Japanese aircraft left their carriers for pearl harbour and despite being picked up on radar the operators did not believe they would have been anything other than friendly aircraft, surely you would know if a wave of aircraft on your radar was friendly or not? On getting to Pearl harbour they destroyed the 4 main runways crippling the American air force and destroying some 350 aircraft and then turned on the US fleet creating complete devestation of the Ships in the harbour. Overall 2000+ men lost their lives. So what am I missing? was it just a complete disaster that caught them so unaware that it was too late? Certainly in the second wave of attacks from Japanese aircraft they appeared better prepared but to a certain extent in vain. They Japanese lost just 29 aircraft and 6 small subs, a small price to pay for such a big victory.
