Withdraw option

[Wicked Pete]

I am currently in QB meeting engagement and after our first clash I came out a little worse for wear. Offense is not an option and my opponent holds the objectives. I have lost the battle but not all my troops.
A ceasefire would not benefit him but a surrender on my part does not sit well with me. I think that a withdraw option would be great in a situation like this. If you hit the withdraw button an exit zone could pop up giving you a more realistic way to end the battle. If your opponent is hell bent on total victory then he could cut of your retreat and destroy you that way.

Any thoughts on this?
