Wednesday, September 24. President Abraham Lincoln suspended the writ of habeas corpus and provided for the military trial of “all Rebels and Insurgents, their siders and abettors within the United States, and all persons discouraging volunteer enlistments, resisting militia drafts, or guilty of any disloyal practice, affording comfort to Rebels against the authority of the United States.” The Preliminary Emancipation Proclamation was released to the public through various newspapers. In Pennsylvania, 14 northern governors met at Altoona and approved emancipation, even though the conference had originally been called to criticize the Lincoln administration’s policies on slavery and the war. Confederate General P.G.T. Beauregard replaced General John C. Pemberton as commander of the Department of South Carolina and Georgia. Federal General Samuel R. Curtis assumed command of the Department of the Missouri. The Confederate Senate approved a seal for the Confederacy.
Thursday, September 25. In Kentucky, Federals under General Don Carlos Buell reached the vital city of Louisville ahead of the Confederate advance. Various skirmishes occurred in Kentucky, Tennessee, and Virginia.
Friday, September 26. Federals conducted an expedition from Helena, Arkansas to Marianna, Tennessee. In the Dakota Territory, skirmishing continued between Federals and Sioux Indians. In Washington, President Lincoln discussed black colonization with his cabinet.
Saturday, September 27. The Confederate Congress passed the Second Conscription Act, which authorized President Jefferson Davis to draft men between 35 and 45 years old for military service. President Lincoln interrogated Major John J. Key and dismissed him from military service for allegedly saying that the object of the Battle of Antietam was “that neither army shall get much advantage of the other; that both shall be kept in the field till they are exhausted, when we will make a compromise and save slavery.” This reflected the view of many Federal troops, and it highlighted Lincoln’s irritation with Federal General George McClellan’s lack of activity since the battle.
