First Lieutenant Cushing was posthumously awarded the Congressional Medal of Honor by the pPresident of the United States on November 6, 2014, 151 years after his death at the Angle at Gettysburg on July 3, 1863, where he commanded Battery A, Fourth United States Artillery. He is likely the last Civil War soldier to who will be so honored. Although many individuals were involved in the effort to give the Medal of Honor to Cushing, this book, first published in 1993, played a critical role.

This expansive, multivolume reference work provides a broad, multidisciplinary examination of the Civil War period ranging from pre-Civil War developments and catalysts such as the Mexican-American War to the rebuilding of the war-torn nation during Reconstruction. The Civil War was undoubtedly the most important and seminal event in 19th-century American history. Students who understand the Civil War have a better grasp of the central dilemmas in the American historical narrative: states rights versus federalism, freedom versus slavery, the role of the military establishment, the extent of presidential powers, and individual rights versus collective rights. Many of these dilemmas continue to shape modern society and politics. This comprehensive work facilitates both detailed reading and quick referencing for readers from the high school level to senior scholars in the field. The exhaustive coverage of this encyclopedia includes all significant battles and skirmishes; important figures, both civilian and military; weapons; government relations with Native Americans; and a plethora of social, political, cultural, military, and economic developments. The entries also address the many events that led to the conflict, the international diplomacy of the war, the rise of the Republican Party and the growing crisis and stalemate in American politics, slavery and its impact on the nation as a whole, the secession crisis, the emergence of the "total war" concept, and the complex challenges of the aftermath of the conflict.
