“Half the Battle” was published by Jerry Pournelle in 1990, in volume 9 of his There Will Be War anthology series, After Armageddon. The story has not been reprinted.
The story opens sometime after an apocalyptic event has destroyed civilization in southern California. A new society has arisen around several small kingdoms, with Turtledove looking at the king of Canoga. When a book is found that describes a machine that the ancients had that can spit bullets, a machine gun, King Byron has his artificers try to replicate the lost device to replace the slow matchlocks his troops are using. The fact that King Byron and his people knew the gun could exist gave them the edge in re-creating it.
The story uses several time jumps to explore where this future will go. In each period, King Byron’s descendants have managed to extend and consolidate the kingdom’s power and in each period, they come across other devices of the ancients that they work to replicate, because knowing it can be done is “half the battle.”
