Today's OneWord: Signal

We saw the smoke signal from ten miles away, where we had built our encampment in the highlands so the enemy forces couldn't see us from their outposts. At first, we weren't quite sure if the whitish gray plumes were a message or merely another incident of a town burning, or a razing by an ally or enemy. But the smell was surprisingly sweet when it reached our nostrils, and we suddenly felt an urge to slumber as we attempted to shoulder our rifles and head towards the steady stream.
