The Battle Report has a minimum of 3 displays, (S), (E), and (1) through up to (7).
(S) is at the Start of the battle, before anybody the first round of battle.
(E) is at the end of the battle, after the last round of battle, but I'm not sure if retreat damage is included.
(1) - (x) where 'x' is the last round of battle, is after each round of the battle.
In the Battle Report, in the upper left corner of the window, click on the circle with 'E', 'S', or (x) to open the list of Battle Report periods to open that period of the battle.
Per default when you open a Battle Report, you always have (E), the end of the battle, displayed. So of course, per default, your units are showing their status after having fought.
