The second line of II Corps was much farther back. I’ll be mapping my book on this soon.

When I do my maps, I think I’ll use the Gilmer/Campbell map as a base because the subsequent Federal fortifications blotted out some important features.

Take a look at the maps from “The Petersburg Regiment” and Maj. John Willian of Mott’s staff, which I’ve allowed this website to display. I’m grateful to A. Wilson Greene for some of the material that allowed me to correct his map.

I have always enjoyed Edward’s maps. His colors and graphics do a great job showing a healthy mix of historical and modern landmarks, which make the maps useful for field study.

I agree that the advance of the 2nd Corps is not as orderly as his map portrays. Specifically, Gibbon’s division remains closer to the JPR and holds more of a north-south line along the road. His placement of Barlow’s and Mott’s divisions are in the correct locations, but Barlow’s left most brigades of MacDougall and Maroney (Irish Brigade) were refused to protect the corps’s flank. As these brigades advanced through thick brush, they were hit in the left flank and rear by Mahone’s brigades, with the brigades of MacDougall, Fraser, and Chaplin receiving the brunt of the flank attack. Mott’s division folded immediately as these brigades are hit from all sides. Some brigades put up no fight at all and fall back, such as McAllister and Brewster. Mahone’s brigades fought almost separately from one another as they advanced east and northeast toward the JPR.

By the final phase of the battle, Mahone’s brigades were located on the road itself fighting around McKnight’s battery (12th NY Battery) and the remnants of the 2nd Corps (mostly Gibbon’s division). Gibbon turned to the brigades of O’Brien (Philadelphia Brigade) and Pierce to hold their position on the JPR and later blamed Pierce for being too slow in launching a counterattack. Pierce–a solid combat commander–was a convenient scapegoat for Gibbon since Pierce had spent the campaign under Mott and Birney and was seen as an outsider in Gibbon’s division. The divisions of Barlow and Mott retreat to an area east of the JPR and attempt to reform.
