Thanks for the link. One thing I kept running across in several of my sources was the frustration with the sighting reported by the reconnaissance aircraft from the Japanese heavy cruiser Tone. With a bit more aggression and professionalism on his part it seems they could have reacted sooner.
I think Yamamoto was highly overrated. He threw away the greatest advantage they Combined Fleet had, superiority in numbers. He scattered his forces all over the Pacific.
