In this brilliant narrative, Amanda Foreman tells the fascinating story of the American Civil War—and the major role played by Britain and its citizens in that epic struggle. Between 1861 and 1865, thousands of British citizens volunteered for service on both sides of the Civil War. From the first cannon blasts on Fort Sumter to Lee’s surrender at Appomattox, they served as officers and infantrymen, sailors and nurses, blockade runners and spies. Through personal letters, diaries, and journals, Foreman introduces characters both humble and grand, while crafting a panoramic yet intimate view of the war on the front lines, in the prison camps, and in the great cities of both the Union and the Confederacy. In the drawing rooms of London and the offices of Washington, on muddy fields and aboard packed ships, Foreman reveals the decisions made, the beliefs held and contested, and the personal triumphs and sacrifices that ultimately led to the reunification of America.
