The Grandfathers War (Unabridged)

Another twisty tale from Murray Leinster about that busy little Med Ship fixing problems throughout the universe. In this case, the med service has received a plea from the planet Pheydra, for medical help take care of casualties from a war that is about to erupt. Since inter-planetary war is of course completely impossible these days, everyone is perplexed but just to be on the safe side, a med ship is sent out to see what the real problem is. Naturally, our hero and Mergatroid are those whose lot it falls to to deal with this sticky situation where a planet's children are at war with their parents.
