When surviving attacking units are recalled to base after a showdown they don't win, do they return ready or exhausted?

Ruling: Units that survive a showdown but don't win are recalled to base in the same state they were in before being recalled. Units that exhausted to move will return exhausted.

Nuances:

• The exhausted state doesn't change unless the game specifically tells it to change
• This applies generally to card states, not just in the showdown recall scenario
