The Staff Ride Handbook for the Overland Campaign, Virginia, 4 May to 15 June 1864, is the tenth study in the Combat Studies Institute's (CSI) Staff Ride Handbook series. This handbook analyzes Lieutenant General Ulysses S. Grant's 1864 Overland Campaign from the crossing of the Rapidan River on 4 May to the initiation of the crossing of the James River on 15 June. Unlike many of CSI's previous handbooks, this handbook focuses on the operational level of war. Even so, it provides a heavy dose of tactical analysis, thereby making this ride a superb tool for developing Army leaders at almost all levels. Designed to be completed in three days, this staff ride is flexible enough to allow units to conduct a one-day or two-day ride that will still enable soldiers to gain a full range of insights offered by the study of this important campaign. In developing their plan for conducting an Overland Campaign staff ride, unit commanders are encouraged to consider analyzing the wide range of military problems associated with warfighting that this study offers. This campaign provides a host of issues to be examined, to include logistics, intelligence, psychological operations, use of reconnaissance (or lack thereof), deception, leadership, engineering, campaign planning, soldier initiative, and many other areas relevant to the modern military professional. Each of these issues, and others also analyzed herein, are as germane to us today as they were 150 years ago.
