Note: While waiting for these detailed orders of battle, please be sure to check out Bermuda Hundred Campaign, Siege of Petersburg, and Appomattox Campaign orbats from the George Nafziger Civil War order of battle collection.
The Siege of Petersburg Order of Battle sub-site of The Siege of Petersburg Online is quite possibly the most ambitious plan for what is an admittedly ambitious project as a whole. The idea is to create a page for every unit, from armies down to company level where necessary, for Butler’s June 9, 1864 offensive against Petersburg and Grant’s nine later attempts to take the city. Unit pages will display items such as leader names and images, unit strengths and armament, links to where the units are mentioned throughout the Siege of Petersburg Online, and links to both parent and child units. This should allow readers and researchers to quickly and easily find units they are interested in on pages which serve as starting points for further information on the units all across my Siege of Petersburg sites.
