Fog of War — Gilbert M. Stack

Despite their impressive victories in the north, Prefect Marcus and the Black Hat Legion stand alone against the full might of Diamonte and Aquamarina. With their home city under siege and the cowardly Lord Totila refusing to lead his host out from behind the walls of Centinela, it falls once again to Marcus to protect his adopted homeland by himself. His only hope is to thread the needle, maneuvering his legion across enemy-occupied Amatista to the one location that might enable him to recapture the initiative in this war. It’s a risky gamble. With multiple armies afield and none of them knowing where the others are, the fate of Amatista will depend on Marcus’ ability to navigate the Fog of War.
