The article draws on two of my writings.
First, the article draws on my book, The Petersburg Regiment in the Civil War: A History of the 12th Virginia from John Brown's Hanging to Appomattox, 1859-1865 (Savas Beatie, 2019). The book won the 2019 Army Historical Foundation Distinguished Writing Award for Unit History. (The distinguished writing was principally by the soldiers; writings from at least 30 of them are quoted in the book.)
The article also draws on an article of mine, The Myth that Mahone's Brigade Did Not Move on July 2, 1863, Gettysburg Magazine, July 2021, Issue 65.
