Second Battle of Cold Harbor Begins

The Battle of Cold Harbor, the final battle of Union Lt. Gen. Ulysses S. Grant's 1864 Overland Campaign during the American Civil War, is remembered as one of American history's bloodiest, most lopsided battles. Thousands of Union soldiers were slaughtered in a hopeless frontal assault against the fortified troops of Confederate Gen. Robert E. Lee.
