Every Civil War buff has heard of the Battle of Chantilly, the bloody 1862 engagement fought in a driving rainstorm only twenty miles from Washington that claimed the lives of two of the Union's most promising generals. Yet few have known the full story of courage and human drama because no one has ever produced a lively and historically accurate account of the battle-until now. Tempest at Ox Hill compellingly evokes this pivotal battle of the war, in which the Union army faced annihilation after Robert E. Lee's overwhelming victory at Second Bull Run. At Chantilly, Virginia, on September 1, 1862, a small Union rearguard faced down some of Lee's best generals. The retreating main Union army, and Washington, were saved, but at a frightening human cost, including the deaths of two Union generalsthe promising Isaac Stevens and the dashing Philip Kearny, a Mexican War veteran who had also served with Napoleon III's imperial guard. And around these two Union generals lay nearly twelve hundred American soldiers, both blue and gray, dead fighting for their chosen cause. Tempest at Ox Hill captures the moment, the courage, and the carnage unforgettably.
