Why would they sit ther ewaiting for the bombardment to fall on them?
Because it's 2 in the morning.
There's no surface battle. If Kondo continues to charge through the 5th then Spruance continues to run southeast throughout the 5th, launching attacks as he goes. Let's say Yamamoto gets lucky and both Akagi and Hiryu's engine spaces prove to be intact, then maybe by midnight on the 5th they're underway. Let's say Yamamoto doesn't get lucky and they're gutted, then by midnight on the 5th they are scuttled. Spruance continues to run southeast throughout the night (he can't risk an encounter), but Kondo breaks off to the north - by midnight they are diverging at a combined speed of maybe 40kt.Depends on where TF 16 is on the afternoon of the 8th & how badly the want the planes. if there has been a surface battle on the 6th or 7th, the US carriers are liable to be operating further east than OTL, & they may have lost more aircraft than OTL.
Pye was 3,000 miles away. Pye can do whatever Pye wants off the coast of California - it'll have no effect whatever on the Battle of Midway.Then there is which direction the US fleet goes that night? I dont think Fletcher, or Spruance, is going to send Pye & Co rushing off into the sunset.
No one thinks there would be a night battle.At this point I'm thinking they will stand east as OTL until dawn, so depending on which direction the Japanese force/s are headed means there may be no night battle as everyones first assumption suggests
