Oh excellent, thank you. I guess I've just been getting unlucky then. Could you explain a bit about the differences in the different 'simulate battle' variables? I assume they alter the outcome of the simulated fight somehow? Looking at this and guessing at their meaning, it looks like the "Do not worry. Our men will guard it." option is the always the worst in both casualties and outcome.
