Battle Cry for Freedom: The Civil War Era

Battle Cry of Freedom covers two decades, the period from the outbreak of the Mexican–American War to the Civil War's ending at Appomattox. Thus, it examined the Civil War era, not just the war, as it combined the social, military and political events of the period within a single narrative framework. Historian Hugh Brogan, reviewing the book, commends McPherson for initially describing "the republic at midcentury" as "a divided society, certainly, and a violent one, but not one in which so appalling a phenomenon as civil war is likely. So it must have seemed to most Americans at the time. Slowly, slowly the remote possibility became horrible actuality; and Mr. McPherson sees to it that it steals up on his readers in the same way."

A central concern of Battle Cry for Freedom is the multiple interpretations of freedom. In an interview, McPherson claimed: "Both sides in the Civil War professed to be fighting for the same 'freedoms' established by the American Revolution and the Constitution their forefathers fought for in the Revolution—individual freedom, democracy, a republican form of government, majority rule, free elections, etc. For Southerners, the Revolution was a war of secession from the tyranny of the British Empire, just as their war was a war of secession from Yankee tyranny. For Northerners, their fight was to sustain the government established by the Constitution with its guaranties of rights and liberties." (wikipedia)
