Percival Drayton was born in the South, but remained loyal to the Union when war came. This resulted in a situation that is often referenced in the study of the Civil War - brother against brother. At the Battle of Port Royal, Percival Drayton commanded the Pocahontas. His brother, Thomas Fenwick Drayton, was a Confederate brigadier general and was also present at Port Royal. During the battle, the Pocahontas fired upon Fort Walker, where Thomas was in command.
Percival wrote in a letter dated 30 November 1861 from Port Royal: "To think of my pitching here right into such a nest of my relations, my brother, William Heyward, Tatnall &c it is very hard but I can not exactly see the difference between their fighting against me and I against them except that their cause is as unholy a one as the world has ever
seen and mine just the reverse."
