This short story is about Mars “the way it once was”, with canals and Martians. An expedition with three crewmembers has landed and finds itself in the way of hordes of “Winter Troops”, a new breed of Martians that feeds off the remnants of the fallen civilization that created the canals.
Told as journal entries, this story isn’t anything special. If it had been any longer I would probably not have finished. it.
