[@Thinslayer] I suppose it really depends on how much you want to write :D If you're willing to do a fair amount of writing, option A is the clear one, and it provides a lot of player-driven interaction. This will hold especially true to any reprimands being made by our Orc Captain, and could perhaps set the stage for either future conflicts or personal affairs. 

Option B will allow everyone to wrap up the battles their own way, but will still more or less be the same as option A. It may indeed require more work on your part since everyone will be making a post to respond directly to, as opposed to everyone being in a potential group :3 It's good if you're looking for a challenge or are dedicated, but I wouldn't recommend it. 

The third option is the easiest, and can easily be the best if done well c: You can get across the brutality of the raid, the soldiers who disobeyed direct orders, and advancing plot points all in one go. It's the easiest to write and is personally my preference ^-^ It'll also allow for a little bit of freedom from characters to decide what they did and will do, though it could be the longest of the three depending on how you write it!

TL;DR: Personally I'd go with some time after, but each has its own pros and cons ;)
