Defenders of the Frontier by Robert Silverberg
My rating: 4.5 out of 5 stars
A fortification protecting a mountain pass in the midst of a desert between two war nations is only manned by eleven men including Surveyor. Once a force of 10,000 when occupying the fort two decades before, the eleven men have over the past few years have killed “the enemy” in ones or two but now their Seeker can’t detect them. Now they begin thinking about if the war is still going on, if they should stay or leave the fort, and if they leave will they be able to function back home. Or is the fort now home?
