I don’t have a lot of diaries in my personal Civil War library but this one has proven extremely helpful. I came across it when writing a future post on Foster’s 1864 attack or “demonstration” as he called it on Charleston. A very complex assault where a number of the key Federal players didn’t file reports in the Official Records of the War of the Rebellion. Major Edward Manigault was a Confederate artillery officer for a good part of the siege of Charleston. General PGT Beauregard asked him to keep a diary of his activities from July 10, 1863, until August 31, 1864, during his service on James Island. There is a lot of information about which guns were where and several detailed maps. For example, he discusses which guns were at Fort/Battery Pringle, as well as Batteries 0-5. One of the maps from the book on a part of Foster’s assault on James Island is shown below, which is the only map I have ever seen detailing it. A truly unique book.
