When Abraham Lincoln expressed gratitude for the northern churches in the spring of 1864, it had nothing to do with his appreciation of doctrine, liturgy, or Christian fellowship. As a collective whole, the church earned the president's admiration because of its rabid patriotism and support for the war. Ministers publicly proclaimed the righteousness of the Union, condemned slavery, and asserted that God favored the Federal army. Yet all of this would have amounted to nothing more than empty bravado without the support of the men and women sitting in the pews. This creative book examines the Civil War from the perspective of the northern laity, those religious civilians whose personal faith influenced their views on politics and slavery, helped them cope with physical separation and death engendered by the war, and ultimately enabled them to discern the hand of God in the struggle to preserve the national Union. From Lincoln's election to his assassination, the book weaves together political, military, social, and intellectual history into a religious narrative of the Civil War on the northern home front. Packed with compelling human interest stories, this account draws on letters, diaries, and church records from 165 manuscript collections housed at 30 different archives and libraries, letters and editorials from 40 different newspapers, and scores of published primary sources. It conclusively demonstrates that many devout civilians regarded the Civil War as a contest imbued with religious meaning. But in the process of giving their loyal support to the government as individual citizens, religious Northerners politicized the church as a collective institution and used it to uphold the Union so the purified nation could promote Christianity around the world. Christian patriotism helped win the war, but the politicization of religion did not lead to the redemption of the state.

The Battle of Ezra Church was one of the deadliest engagements in the Atlanta Campaign of the Civil War and continues to be one of the least understood. Both official and unofficial reports failed to illuminate the true bloodshed of the conflict: one of every three engaged Confederates was killed or wounded, including four generals. Nor do those reports acknowledge the flaws - let alone the ultimate failure - of Confederate commander John Bell Hood's plan to thwart Union general William Tecumseh Sherman's southward advance. In an account that refutes and improves upon all other interpretations of the Battle of Ezra Church, noted battle historian Gary Ecelbarger consults extensive records, reports, and personal accounts to deliver a nuanced hour-by-hour overview of how the battle actually unfolded. His narrative fills in significant facts and facets of the battle that have long gone unexamined, correcting numerous conclusions that historians have reached about key officers' intentions and actions before, during, and after this critical contest. Eleven troop movement maps by leading Civil War cartographer Hal Jespersen complement Ecelbarger's analysis, detailing terrain and battle maneuvers to give the reader an on-the-ground perspective of the conflict. With new revelations based on solid primary-source documentation, Slaughter at the Chapel is the most comprehensive treatment of the Battle of Ezra Church yet written, as powerful in its implications as it is compelling in its moment-to-moment details.
