Here’s Mark Grimsley speaking at the Army Heritage and Education Center in 2010 on the Overland Campaign.
From the video’s description: “The Virginia campaign of Spring 1864 was a single, massive operation stretching hundreds of miles. The story of the campaign is also the story of the demise of two great armies. The scale of casualties and human suffering that the campaign inflicted makes it unique in U.S. history. Mark Grimsley’s study, however, is not just another battle book. Grimsley places the campaign in the political context of the 1864 presidential election; questions conventional interpretations; and explores the campaign as a touchstone of the Southern myth of the ‘Lost Cause.’
“Professor Grimsley is currently on leave from The Ohio State University where he teaches American military history with an emphasis on the Civil War. He is the author of The Hard Hand of War: Union Military Policy Toward Southern Civilians, 1861-1865 (1995), which won the Lincoln Prize. His other work includes Warfare in the Western World; Civilians in the Path of War (2002) (with Clifford J. Rogers); The Collapse of the Confederacy (2001) (with Brooks D. Simpson); And Keep Moving On: The Virginia Campaign, May-June 1864 (2002), Gettysburg: A Battlefield Guide (1999) (with Brooks D. Simpson), and Shiloh: A Battlefield Guide (2006) (with Steven E. Woodworth). He is currently writing a book on the connections between the 1864 military and political campaigns for the ‘Pivotal Moments in American History’ series, published by Oxford University Press.”
Mark, by the way, is back at Ohio State.
