Hi, I haven't tried this before but wanted to know what happens in this situation:

I traditional march attack an enemy and take 200 acres.

The enemy ambushes my army and gets back 100 acres.

I cast Anonymity. I then ambush the enemy ambush. What happens here?

Does Anonymity work on my ambush attack, making that ambush not ambushable?

Do I still get back 50 acres or do I suffer the anonymous -15% gains and instead get 42 acres?
