Book excerpt: In the long and bitter prelude to war, southern transplants dominated California government, keeping the state aligned with Dixie. However, a murderous duel in 1859 killed "Free Soil" U.S. Senator David C. Broderick, and public opinion began to change. As war broke out back east, a golden-tongued preacher named Reverend Thomas Starr King crisscrossed the state endeavoring to save the Golden State for the Union. Seventeen thousand California volunteers thwarted secessionist schemes and waged brutal campaigns against native tribesmen resisting white encroachment as far away as Idaho and New Mexico. And a determined battalion of California cavalry journeyed to Virginia's Shenandoah Valley to battle John Singleton Mosby, the South's deadliest partisan ranger. Author Richard Hurley delves into homefront activities during the nation's bloodiest war and chronicles the adventures of the brave men who fought far from home.
