"Volunteers Wanted! for Company A," King & Baird, 1861

A Call to Arms

The day after Fort Sumter fell, Lincoln called for 75,000 volunteers to suppress the southern rebellion and save the Union. Tens of thousands of men eagerly responded, enlisting for ninety days, the amount of time most people thought the war would last. Lincoln’s decision to forcefully reclaim the South precipitated the departure of four additional states (Virginia, North Carolina, Tennessee, and Arkansas), bringing the total number of Confederate states to eleven.
