Short Story
Bombardment in Reverse
- by Norman L. Knight
- Astounding, February 1940
Jamie Todd Rubin wrote about this story as part of his Vacation in the Golden Age, and I got a pdf copy on Thanksgiving Day in 2012. The story tells of two alien nations at war—a somewhat amateurish was by Martian or Terrestrial standards, but one in which time-traveling weapons target where the enemy was in the past.
The Nyandrians are attacking Strofander with shells which traverse not only space, but time as well.
