The Crown OB in this book is based on Stewart's muster rolls from the day before the battle. Previously I used Novak's OB which must be based on the same source since it agrees exactly. Previously I wasn't sure if the foraging party was included in these numbers. The book's numbers for Greene's army are ~2,200 instead of Novak's ~ 2,000, but then notes that 200 were left to guard baggage. I suspect they were militia, since the book's SC militia numbers are about 200 more than Novak's.
Greene's army deployed in two lines, each with about the same frontage as Stewart's single line. Both used the standard two-rank "loose files" formation common since 1776. This indicates Greene had a larger number of troops than Stewart. Interestingly, the book notes the 3rd Foot, the Buffs, were new in country and the first part of the British line to give way.
The book says Stewart lamented two things after the battle: having sent the foraging party which so depleted his fighting strength (but gave warning of the impending attack) and his lack of cavalry.
I have been interested in this battle for a very long time. Back in 1959 I badgered my mother into buying me a book about Francis Marion, inspired by the Disney TV series Swamp Fox. The young adults biography ended with the Battle of Eutaw Springs, and a line drawing of Marion's men in a firing line. The book was my first clue about the difference between history and the Hollywood version.
