If a unit is stunned while conquering an empty battlefield, does it successfully conquer or get recalled?

Ruling: A stunned unit conquers an empty battlefield. Stun only prevents dealing combat damage, but does not affect conquest of empty battlefields.

Nuances:

• If the battlefield had enemy units, the stunned attacker would be recalled if it didn't take damage equal to or greater than its might
• Stun does not prevent conquest mechanics, only combat damage
