I have a story in this anthology, compiled and edited by Mark Paxson. The full description:
A doctor in Napoleon’s army. A young man seeking fame fighting for the North in the Civil War. Tributes to fathers who served. Vignettes as told by those who lived through them. Speculative tales of wars of a different kind. These stories, and more, fill this anthology with the adventures of veterans, in and out of war.
If you don’t want to buy it from Amazon, it’s available from a number of other outlets here. All proceeds beyond costs will be donated to the Wounded Warrior Project.
