A Proclamation by the President of the United States, April 15, 1861

As Commander in Chief, President Abraham Lincoln responded to the Confederate attack on Fort Sumter by calling for 75,000 militia volunteers. Their first duty was to repossess federal property seized from the Union by the seven seceded states. Lincoln also used his constitutional authority to convene an extraordinary session of Congress for July 4, 1861.
