Emancipation Proclamation.

Initially, the Civil War between the North and the South was fought by the North to prevent the secession of the South and preserve the Union. Ending slavery was not a goal. That changed on September 22, 1862, when President Abraham Lincoln issued his Preliminary Emancipation Proclamation, which stated that slaves in those states or parts of states still in rebellion as of January 1, 1863, would be free. One hundred days later Lincoln issued the Emancipation Proclamation declaring "that all persons held as slaves" within the rebellious areas "are, and henceforward shall be, free." Lincoln's bold step was a military measure by which he hoped to inspire the slaves in the Confederacy to support the Union cause. Because it was a military measure, the proclamation was limited in many ways. It applied only to states that had seceded from the Union, and left slavery untouched in the border states. Although the Emancipation Proclamation did not end slavery, it did fundamentally transform the character of the war. Henceforth, every advance of Federal troops expanded the domain of freedom. Moreover, the proclamation announced the acceptance of black men into the Union Army and Navy. By the end of the war, almost 200,000 black soldiers and sailors had fought for the Union and their own freedom.

Letter Written in Cipher on Mourning Paper by Rose Greenhow.

Rose O'Neal Greenhow was a spy for the Confederacy during the American Civil War. As a young woman in Washington, she befriended many influential politicians, including President James Buchanan and South Carolina Senator John C. Calhoun, who played a role in shaping her dedication to the South. During the Civil War, Greenhow wrote ciphered (secret code) messages to the Confederates, providing information about Union military plans. Confederate President Jefferson Davis credited her with helping the South win the First Battle of Bull Run. Greenhow sent a message about Union troop movements in time for Brigadier Generals Pierre Beauregard and Joseph E. Johnston to meet at Manassas, Virginia. A young woman working with Greenhow named Betty Duvall carried the message wrapped in a tiny black silk purse and hidden in a hair bun. Head of U.S. Intelligence Service Allan Pinkerton observed Rose Greenhow as part of his counterintelligence activities and found sufficient evidence to place her under house arrest. She later was transferred to prison and then deported to Richmond, Virginia. Shown here is one of her encoded letters.
