If you are going for this Achievement, DO NOT mess with already beaten campaigns!
That will reset the progress of the campaign and you have to beat it without losing once again.

If you want to do it legitimently, you have to go back to menu before you lose. That way, your progress won't get lost, as well as it doesn't caunt as lost.

That's the best guide for it. Credits to MrBlackSkull
