Like Valhalla, this anthology collection of short fiction resurrects ghost soldiers, fallen soldiers to fight another day on supernatural and often otherworldly battlefields. Some stories by current SF/Fantasy authors, some by older authors.
Franklin Robert Adams (August 31, 1933 - January 4, 1990) was an American science fiction and fantasy writer, formerly a career soldier. He is best known for his "Horseclans" books. He wrote as Robert Adams, an abbreviated form of his full name.
Adams was an early pioneer of the post-holocaust novel. His Horseclans novels are precursors to many of today's attempts at this type of story, many of which do not exhibit his painstakingly detailed world view or extraordinary plot follow-through (many of his Horseclans books are so interlinked that they make sense only when read in order; he did not create many "stand alone" books in the series).
Hallmarks of Adams' style include a focus on violent, non-stop action, meticulous detail in matters historical and military, strong description, and digressions expounding on various subjects from a conservative and libertarian viewpoint.
Fantasy stories all involving some type of ghost army or legion. I generally enjoyed it, but I didn't find it outstanding. "The Spectre General" by Theodore Cogswell was memorable, although it could have been shortened and tightened. Kipling's "The Lost Legion" was good. My favorite tale was of an enduring friendship, called "The Roll-Call of the Reef," by Sir Arthur Quiller-Couch.
