The Second Massachusetts Cavalry included the only organized group (5 companies totaling 504 men) from California to fight in the east during the Civil War. Led by a young Boston aristocrat, Colonel Charles R. Lowell, these men began their wartime careers in Northern Virginia in 1862, clashing with the partisan rangers of Major John S. Mosby, in a deadly world of guerrilla warfare. In August of 1864, the regiment was assigned to Major General Phil Sheridan's Army of Shenandoah and served through all of the battles in the victorious campaign to clear the valley of Confederates, witnessing the final surrender at Appomattox Courthouse. This account tells what these men from California and Massachusetts accomplished, how they communicated, and how they viewed themselves. The book contains three appendices that list the battle casualties of the regiment during its largest engagements. Photographs and a bibliography are also included.
