Do you mean you want to know all of the details of every battle?
Every bit of information detaining to what I think you are describing, is there to find right now, unless I am massively misunderstanding your question?
In the commanders report, you can filter battles to see whatever kind of result you want, retreat, held, rout, surrender, etc etc
Then you can further filter to see which battles had the most/least in AFV's, men, guns, planes, for either the attacker or defender
You then click on said battle in the commanders report, to be taken directly to the battle on screen
Then you can look at the combat details, to see every single disrupted, damaged and destroyed element
Half of learning this game is understanding it's UI, when it comes to UI, the commanders report is usually your best bet, to filter out the white noise and find what you are looking for
