Hi,
Just to be sure. The battle created by an Ambush is considered to be in the Strategy phase and not in an additional Attack phase ?
Ambush Limited: Target your unbowed Personality: Create a battlefield (not at any province). Assign your Personality's unit to attack there. Assign another player’s target unit to defend there, even if its Personality is bowed. Other units will not move there. Fight a battle there (after this action's resolution). After the battle ends, lose 5 Honor.

Yes(-ish*); as in SE, the CE Ambush does not create a separate Attack Phase.
*The "ish" being that there is no "Strategy Phase". Only the card-type name changed; it's still called the "Action Phase".
