After the Confederates fired on the US Army garrison on the island of Fort Sumter in Charleston Harbour, Lincoln could not declare war, because that would mean recognising the Confederacy as a sovereign nation.
Instead he appealed for volunteer troops to put down a rebellion of the Southern states and bring them back into the USA.
Lincoln said he would send food but no arms to the fort.
One of the first responses was to send warships to the Charleston Harbor. He also asked for 75,000 volunteers for a term of three months to the Army. Almost everyone thought the "rebellion" would be short lived. Lincoln also put into motion part of the socalled Anaconda Plan and ordered the US Navy to blockade all Southern ports.
By a special Proclamation, Lincoln declared the existence of an insurgency, and asked the State Governors 75,000 volunteers to repress it.
The battle that was fought after Fort Sumter was Manassas Junction.
Fort Sumter, a fort that remained in the union, was running low on supplies. President Lincoln had to decide whether or not to supply fort. If he did he risked war if not he would giving in to the rebels [the confederate]. Lincoln informed South Carolina that he would be resuplying Fort Sumter. Confederate leaders decided to take over Fort Sumter before the supplies ships arrived. On April 12, 1861, the confederates opened fire on Sumter. the attack lasted for 34 hours until the fort had to surrender. The Conferderate attack on Fort Sumter was the beginning of the Civil War.
