Let's say I assign Kaiu Genji (4F) to attack at a province controlled by a player playing Shattered Peaks Castle (8PS)
The Defender chooses not to oppose my attacking personality.
Both players pass.
I clearly do not have enough force to take the province.
However, do I "win" the battle?
Do I *have* to destroy an opposing army or province to win the battle? It does not appear so.
From the CR,
1. Determine Outcome: Total the Force of each army (see Total Force). Whichever army has the highest total Force wins.
A side with no units has zero Force for purposes of this comparison, and is not affected by things that directly alter the Force of an “army”.
The calculation and comparison of army force is made only once. Any changes to army total Force after this point (e.g., units on the winning side being destroyed due to Reactions) do not alter the outcome.
The winning army’s leader (the Attacker or Defender) is the winner of the battle.
If both armies have the same total Force and both armies contain one or more units, the battle is a tie.
Any other result (such as an army with total Force of zero versus a side with no units) has no defined outcome, in which case, nothing happens in step 2.
