2020 UPDATE: I am continuing this work in much greater detail at The Siege of Petersburg OnlinePlease come over and join me!

Back to Brett’s Regimental Level Orders of Battle

Project Goal:

The goal of my Petersburg Campaign Project is to try to create a set of Excel Spreadsheets which will document the Order of Battle for the Union and Confederate Armies for each of the Nine Offensives during the Petersburg Campaign of June 15, 1864-April 2, 1865. These OOBs will be down to the regimental level, and I hope to include unit armament (i.e. which weapons each unit carried, examples include Springfiled Rifle Musket, Enfield Rifled Musket, Smoothbore, Henry Repeater, etc.), muster in date, muster out date, various ways to measure unit quality (on a scale of A-E, with A being the best and E the worst), and most importantly, the strength of each regiment. I know going in that there are many cases where regimental strengths cannot be found. I will attempt to estimate these using various sources.

Reason for Project:

There are a few reasons I wish to do this:

1) I have always been interested in unit strengths down to the Regimental Level. In many cases, authors neglect this information, when for a lot of people this would add immensely to their understanding of the struggle. When someone says two Confederate Divisions drove away two Union Corps, that does not tell me much. When you come to find out later that a Confederate Division is usually larger than its Union counterpart at this stage of the war, the perception changes.

2) The Battle and ensuing Siege of Petersburg is not at all well-covered in terms of books, essays, articles, maps and the like. I always ignored this part of the war, only to find out later that many fascinating battles took place over the life of the Siege. It is my hope that this project can add at least a little to everyone’s understanding of the Siege.

3) I am a wargamer almost as much as I am a military history buff. I would like to take this information and use it in future Civil War games which come out. Current examples of the types of games I am talking about include Age of Rifles, Civil War Generals 2, the Battleground games from Talonsoft, and the Campaign Series by HPS, for whom I am an uncompensated playtester. The information contained within the spreadsheets will be available to anyone who wants it free of charge, but I hope to eventually make at least a little money off of this down the road by way of designing a game for a wargaming company. There is nothing in the works currently.

Sources I Have:

Sources I currently have include the Official Records on CD Rom, The Southern Historical Society Papers on CD Rom, every Civil War Times Illustrated ever produced, almost every America’s Civil War and Blue & Gray ever produced, every North & South ever produced, Battles & Leaders of the American Civil War, The Official Records Atlas in book form, Dyer’s Compendium, the ten of the eleven volumes (missing only the Index of larger formations) of Sifakis’ Compendium of the Confederate States Army and Ray Sibley’s The Confederate Order of Battle: The Army of Northern Virginia. The books I own on Petersburg are located HERE.

Work Completed:

I am currently working on the initial Union OOB for June 15, 1864. After it is complete as far as armament and unit quality, I will make the other eight OOBs representing the other 8 Offensives during the Siege. I’m also moving forward rapidly on the Confederate OOBs for the entire Siege. I am basing the initial drafts of these Confederate OOBs almost entirely on Ray Sibley’s The Confederate Order of Battle: The Army of Northern Virginia.

    Can you tell me the Confederate OOBs that included Company A, Stark’s Battalion, Virginia Light Artillery?

    Nice Job!

    Thank you! I do hope to revisit these OOBs sometime in the future. I want to establish “baseline” OOBs so that I can then research reported unit strengths throughout the Siege.

    Unfortunately, since it has been 2 1\2 years, I can’t give you specifics on any given unit. I would suggest downloading the excel file and using the “Find” tool to look for your unit.

    Thank you! I have also always been interested in unit strengths as part of an OB and find this information very helpful. Great work!
