Amphibious operations feedback

[Nicals]

I'm learning this game, reading the manual while playing again and again the Husky Introductory Scenario.
I'm starting to understand how it work and feel more and more ready to start a longer campaign.
There is just this last one thing that bothers me.

I know I can have some feedbacks on the battles that occured (F11). This key allows me to have a list of all battles I initiated this turn or that were initiated by the opponent on its last turn.
But it cannot display what happens after an amphibious operation took place.
It seems that I can only know what is happening during the turn resolution phase.
Is that true ? Can't I bring back those amphibious operation battle details on the next turn ?

Another battle related question: the battle resolution screen gives a lot of details about who died and who didn't at the end of the battle.
But I'm struggling to find information on how the battle went.
I can see my raw CV was 140 and reduced to 45 for exemple, but couldn't find any information on why it did so.
I feel this lack of information prevents me from analyzing my mistakes and learning from them.
Is there any way to analyze a battle to understand why we loose instead of how we lost ?
