1864 in the American Civil War was the penultimate and pivotal year of the conflict, marked by a relentless, coordinated Union offensive across all theaters. Under the overall strategic direction of Lieutenant General Ulysses S. Grant, Union armies engaged in a war of attrition against the dwindling resources and manpower of the Confederate States of America. The year witnessed some of the war's bloodiest campaigns, decisive shifts in public sentiment, and the political consolidation of President Abraham Lincoln's war aims.

Overview of the year

The strategic landscape was fundamentally reshaped in March 1864 when Abraham Lincoln promoted Ulysses S. Grant to General-in-Chief of the United States Army. Grant implemented a coordinated strategy to pressure the Confederate States Army on multiple fronts simultaneously, most critically against General Robert E. Lee's Army of Northern Virginia and General Joseph E. Johnston's Army of Tennessee. This approach led to a staggering casualty toll in campaigns like the Overland Campaign and the Atlanta Campaign, testing Northern morale but ultimately crippling Southern capacity. Key victories at the Battle of Mobile Bay, the Capture of Atlanta, and the Valley Campaigns of 1864 provided crucial boosts for Abraham Lincoln's re-election campaign, ensuring the war would continue until Confederate surrender.

Eastern Theater

Grant, accompanying Major General George G. Meade's Army of the Potomac, launched the Overland Campaign in May, engaging Robert E. Lee in a series of brutal, bloody battles. These included the Battle of the Wilderness, the Battle of Spotsylvania Court House, and the Battle of Cold Harbor, which resulted in massive Union casualties but forced Lee into a defensive siege at Petersburg, Virginia. The Siege of Petersburg began in June, becoming a protracted trench warfare stalemate that stretched Confederate lines to the breaking point. In a daring raid on Washington, D.C., Lieutenant General Jubal Early's Army of the Valley was defeated at the Battle of Fort Stevens in July, the only time a sitting U.S. president came under direct enemy fire.

Western Theater

Major General William Tecumseh Sherman, commanding the Military Division of the Mississippi, opposed Joseph E. Johnston in the Atlanta Campaign. Through flanking maneuvers and battles at Resaca, Kennesaw Mountain, and Peachtree Creek, Sherman advanced on the critical rail hub of Atlanta. Following Johnston's replacement by General John Bell Hood, the Confederate States Army launched several failed offensives, culminating in the Battle of Atlanta and the city's fall on September 2. This victory, followed by Sherman's subsequent March to the Sea, shattered Confederate morale in the heartland and severed vital supply lines.

Trans-Mississippi Theater

The theater was largely characterized by guerrilla warfare and smaller-scale operations, though a significant conventional campaign occurred in the spring. The Red River Campaign, led by Major General Nathaniel P. Banks, aimed to capture Shreveport, Louisiana and secure cotton resources but was thwarted by Confederate forces under General Richard Taylor at the Battle of Mansfield and Battle of Pleasant Hill. In Missouri, brutal irregular conflict continued, exemplified by the Battle of Pilot Knob and the Centralia Massacre. Union efforts to project power into Texas met with limited success, leaving the region under tenuous Confederate control but strategically isolated.

Naval operations

The Union Navy's blockade of the Confederate coastline, part of the Anaconda Plan, tightened decisively. The most famous naval action was Rear Admiral David G. Farragut's victory at the Battle of Mobile Bay in August, where he famously declared "Damn the torpedoes, full speed ahead!" to secure the last major Gulf of Mexico port. The CSS Alabama, a notorious Confederate States Navy commerce raider, was finally sunk by the USS Kearsarge off Cherbourg-France in June. On inland waters, Union gunboats continued to support army operations along the Mississippi River and its tributaries, combating Confederate cavalry raids and fortifications.

Politics and elections

The political war was as consequential as the military one. The National Union Party convention renominated Abraham Lincoln, with Andrew Johnson as his vice-presidential candidate, on a platform demanding unconditional surrender. The Democratic Party, nominating General George B. McClellan, campaigned on a platform calling for a negotiated peace, which was undercut by the fall of Atlanta. Lincoln's decisive re-election in November, carrying every state except Kentucky, Delaware, and New Jersey, was interpreted as a popular mandate to continue the war to its conclusion and to pass the Thirteenth Amendment abolishing slavery.
