Timeline

1. January 1863

   Emancipation Proclamation

   In an effort to placate the slave-holding border states, Lincoln resisted the demands of radical Republicans for complete abolition. Yet some Union generals, such as General B. F. Butler, declared slaves escaping to their lines "contraband of war," not to be returned to their masters. Other generals decreed that the slaves of men rebelling against the Union were to be considered free. Congress, too, had been moving toward abolition. In 1861, Congress had passed an act stating that all slaves employed against the Union were to be considered free. In 1862, another act stated that all slaves of men who supported the Confederacy were to be considered free. Lincoln, aware of the public's growing support of abolition, issued the Emancipation Proclamation on January 1, 1863, declaring that all slaves in areas still in rebellion were, in the eyes of the federal government, free.

2. March 1863

   The First Conscription Act

   Because of recruiting difficulties, an act was passed making all men between the ages of 20 and 45 liable to be called for military service. Service could be avoided by paying a fee or finding a substitute. The act was seen as unfair to the poor, and riots in working-class sections of New York City broke out in protest. A similar conscription act in the South provoked a similar reaction.

3. May 1863

   The Battle of Chancellorsville

   On April 27, Union General Hooker crossed the Rappahannock River to attack General Lee's forces. Lee split his army, attacking a surprised Union army in three places and almost completely defeating them. Hooker withdrew across the Rappahannock River, giving the South a victory, but it was the Confederates' most costly victory in terms of casualties.

4. May 1863

   The Vicksburg Campaign

   Union General Grant won several victories around Vicksburg, Mississippi, the fortified city considered essential to the Union's plans to regain control of the Mississippi River. On May 22, Grant began a siege of the city. After six weeks, Confederate General John Pemberton surrendered, giving up the city and 30,000 men. The capture of Port Hudson, Louisiana, shortly thereafter placed the entire Mississippi River in Union hands. The Confederacy was split in two.

   These photographs include three which William R. Pywell took in February 1864, referring back to Grant's brilliant campaign of the previous summer.

5. June-July 1863

   The Gettysburg Campaign

   Confederate General Lee decided to take the war to the enemy. On June 13, he defeated Union forces at Winchester, Virginia, and continued north to Pennsylvania. General Hooker, who had been planning to attack Richmond, was instead forced to follow Lee. Hooker, never comfortable with his commander, General Halleck, resigned on June 28, and General George Meade replaced him as commander of the Army of the Potomac.

   On July 1, a chance encounter between Union and Confederate forces began the Battle of Gettysburg. In the fighting that followed, Meade had greater numbers and better defensive positions. He won the battle, but failed to follow Lee as he retreated back to Virginia. Militarily, the Battle of Gettysburg was the high-water mark of the Confederacy; it is also significant because it ended Confederate hopes of formal recognition by foreign governments. On November 19, President Lincoln dedicated a portion of the Gettysburg battlefield as a national cemetery, and delivered his memorable "Gettysburg Address."

   Photographs of the battleground began immediately after the battle of July 1-3. This group of photographs also includes a scene of Hooker's troops in Virginia on route to Gettysburg.

6. September 1863

   The Battle of Chickamauga

   On September 19, Union and Confederate forces met on the Tennessee-Georgia border, near Chickamauga Creek. After the battle, Union forces retreated to Chattanooga, and the Confederacy maintained control of the battlefield.

   Meade in Virginia—August-November 1863

   After the Battle of Gettysburg, General Meade engaged in some cautious and inconclusive operations, but the heavy activity of the photographers was confined to the intervals between them—at Bealeton, southwest of Warrenton, in August, and at Culpeper, before the Mine Run Campaign.

7. November 1863

   The Battle of Chattanooga

   On November 23-25, Union forces pushed Confederate troops away from Chattanooga. The victory set the stage for General Sherman's Atlanta Campaign.

   Chattanooga—September-November 1863

   After Rosecrans's debacle at Chickamauga, September 19-20, 1863, Confederate General Braxton Bragg's army occupied the mountains that ring the vital railroad center of Chattanooga. Grant, brought in to save the situation, steadily built up offensive strength, and on November 23- 25 burst the blockade in a series of brilliantly executed attacks. The photographs, probably all taken the following year when Chattanooga was the base for Sherman's Atlanta campaign, include scenes on Lookout Mountain, stormed by Hooker on November 24.

   The Siege of Knoxville—November-December 1863

   The difficult strategic situation of the federal armies after Chickamauga enabled Bragg to detach a force under Longstreet to drive Burnside out of eastern Tennessee. Burnside sought refuge in Knoxville, which he successfully defended from Confederate assaults. These views, taken after Longstreet's withdrawal on December 3, include one of Strawberry Plains, on his line of retreat. Here we have part of an army record: Barnard was photographer of the Chief Engineer's Office, Military Division of the Mississippi, and his views were transmitted with the report of the chief engineer of Burnside's army, April 11, 1864.
