There are four main books on The Crater, the culmination of Grant’s third offensive at Petersburg. They all cover, in varying degrees of detail, Hancock’s thrust north of James River to threaten Richmond and draw Confederates away from the Cockade City, maximizing the chances for success when the mine was exploded.
The first is “The Horrid Pit,” by Michael Kavanaugh and William Marvel. This book was written before the internet brought so many original and published regimental sources so accessible but it is still an excellent introduction to the subject.
I thought Richard Slotkin’s “No Quarter” was particularly disappointing for its many errors, given that it came from a major publishing house. It brings little to the party.
John Schmutz’ “The Battle of the Crater” brings to light some new unpublished material, but it still needs significant editing.
If I were limited to reading one book about The Crater, it would be Earl Hess’ “Into the Crater,” which has particularly good maps and brings new unpublished material to light.
There is still plenty of unpublished material on The Crater that has not been integrated into a major book on the subject. A systematic search of newspapers probably would bring more to light. A definitive book on this terrible struggle has therefore not yet been written.
My take on The Crater is that the layout of the June 18 Confederate line affected the battle significantly. Meade was right that Pegram’s Salient was a poor location for the mine because the salient stood between two higher points. Grant appears to have failed to convey to Burnside the experience gained from mines exploded at Vicksburg. Meade’s interference with Burnside’s plan and Grant’s support of Meade after letting Burnside go so far violated fundamental principles of management.
Next—beyond the Crater.
