Marching Through Peachtree — Harry Turtledove

FREE THE BLONDES!

(America's Civil War Turned Upside Down)

A terrible civil war was tearing apart the kingdom of Detina, a land which could no longer be half serf and half free. When the new ruler, King Avram, announced his intent to liberate the blond serfs upon which the northern provinces depended, Detina was torn in two, and the rebellious north took Avram's cousin, Grand Duke Geoffrey, as their king.

Neither side could expect an easy victory. The south was larger and wealthier, but the north had better soldiers and more powerful wizards. Led by officers riding unicorns, supplied by flying carpets, both sides had been clashing for three years when Count Thraxton, a conceited wizardgeneral whose opinions of his spell-casting ability far outstripped the reality, bungled a spell which backfired disastrously against his own side, giving the Unionists a decisive victory.

But the war was far from over: Thraxton the idiot had been relieved of command; which meant that the south faced a far more competent general: Joseph the Gamecock. And Joseph and his troops were determined to hold Peachtree Province against the loyalist troops. They had occupied Rockface Rise, which offered only two narrow places where the Unionists could come at them, and had further fortified it with trenches and catapults. When the southern army attacked, they would face formidable obstacles both natural and manmade, as well as the repeating crossbows of the troops and the deadly sorcerous storm and lightning wielded by the northern wizards.

Still, the very survival of Detina as one united realm was at stake, and King Avram's forces had no choice but to attack, no matter what the odds, no matter how desperate the situation ....
