In Virginia, the Union Army crosses the Rapidan River and begins Grant's Overland Campaign
The Overland Campaign was a massive and sustained offensive General U.S. Grant designed to draw the Army of Northern Virginia to battle in defense of Richmond. A series of battles were fought on this design, including the Wilderness and Cold Harbor. Casualties were very heavy but Grant wore down Lee and achieved the strategic success of crossing the James River and besieging Petersburg. (By John Osborne)
