About the sprites, I think that if they're not working the way you're doing it, then (if this isn't the way you're already doing it) you could get all of the images that you'll use (once each) by pasting the URL into the "Insert Image" button in the formatting toolbar (mountains; yellow background) and then copy-pasting each of them wherever appropriate. But it might not be worth the effort. This was definitely a very good read for me; it's always nice to read a well-written warstory.
I won't parrot everything everyone has said so far, but I'll say that alongside the questionable plays (I think the number 3 comes to my head) there were also a few nice plays (maybe 2 particularly nice ones). But it was your comments that made it good. Sure, at times they were a little... "fluffy." But they pretty much all had at least your thought process for the moves, which was great.
All in all, good job! And thanks for the warstory.
