There is metaphorical reference in Chapter 1, page 9, where I state the Civil War’s opening salvo occurred on April 6. Every Civil War aficionado knows the bombardment of Fort Sumter began on April 12. The “opening salvo” reference is political in nature and refers to Lincoln’s April 6, 1861 message to South Carolina’s Governor Pickens that the fort would be resupplied with provisions but not men or arms, except in case of attack on the fort. It reads as the opening of the bombardment and requires clarification.
The actual bombardment of Fort Sumter, or literal “opening salvo,” began at 4:30 AM on April 12, 1861 with a single 10-inch mortar round from Fort Johnson. Major Anderson formally surrendered the post at 2:30 PM, April 13.
During the editing process, we dropped a subsequent clause on the sentence explaining the reference. The author regrets any confusion.
