To The Supreme Commander in Chief:
Activity has increased on my Right flank. The enemy has even raised a False banner in the hopes of confusing my sentries. I'm expecting more diversionary tactics, such as an artillery barrage and possibly some skirmishes.
My troops are on high alert. We are still expecting the main thrust to come on our Left. I'm in the hope that this current ploy will not take long, but I have instructed my commanders to be prepared, this ruse could go on for quite some time, maybe months.
Your humble servant always
