Quote context

[...]

- Sir, Admiral Nagumo's carrier force should be warned immediately.

- Admiral Nagumo must have picked up the transmission at the same time we did.

- Suppose he didn't. He will assume Operation K went forward and that the American carriers are at Pearl Harbor.

- And that is where our latest intelligence reports place them.

- What latest intelligence reports, Captain? Have any of our submarines sighted the American fleet in the last 20 hours?

- No, sir.

- But there is no logical reason for the Americans to have moved their carriers away from Pearl Harbor.

- At any rate we must not break radio silence and risk letting them know where we are.

- Sir, the element of surprise is one of the most important aspects of our attack.

- Admiral, this is our search plan. An air search involving 22 PBYs, each plane to fly a spoke 700 miles out, covering an eight -degree sector.

- That'll give us a 180-degree look at anything coming in from the west, and still leave us an excellent flanking area northeast of Midway for our carriers.

- Have it put into operation immediately.

- Aye-aye, sir.
