I remember reading a short story, somewhen in the late 90s, about an alien invasion.
Earth is overwhelmed, all its ships are disintegrated, and when they are about to lose, they are told they are participating in a galactic wargame, kinda like a chess game. The twist at the end was that
None of their ships were destroyed, they were merely teleported somewhere until the end of the game.
Maybe this could have been written by Asimov, but I'm not sure. BTW, I read it in French.
