The Confederate President Jefferson Davis gave command to Southern forces led by General Beauregard to bomb the fort on April 12 to force it to surrender, which happened.
The Northern states all supported Lincoln. He called for the fortresses to be reclaimed and the Union to be preserved. At the same time, 75,000 volunteers were called up for a period of 90 days. In the previous months, several governors had trained their militias. Their troops started to move the next day.
