Final answer:
The correct chronological order of events during Jefferson Davis's early presidency is the bombing of Fort Sumter, the appointment of Robert E. Lee, and lastly, the sending of an unsuccessful peace commission.
Step-by-step explanation:
To determine the correct chronological order of events related to the role of Jefferson Davis in his early days as president of the Confederacy, we look at historically documented events. The first event is the bombing of Fort Sumter which started on April 12, 1861, following President Lincoln's attempt to resupply the fort. After this event, during the summer and fall of 1861, Jefferson Davis was occupied with the organization and management of the Confederacy. On November 6, 1861, Davis was elected the permanent President of the Confederacy. Further into his presidency, Davis faced military decisions, including the appointment of Robert E. Lee as the commander of the Army of Northern Virginia in June 1862. The unsuccessful peace commission to Washington, DC, to halt hostilities occurred later during the war.
Given these events, the correct chronological order is first the bombing of Fort Sumter, then the choosing of Robert E. Lee as the commander, and lastly, the peace commission.
