Federal (Union) Colonel Edward Cross (L) forms his troops prior to the battle in "The Wheatfield" during re-enactment activities to recognise the 150th anniversary of the US Civil War battle in Gettysburg, Pennsylvania, on July 5. Cross, wearing a black headband, had a premonition that he would die in the battle which proved correct.  Gettysburg officials are expecting 250,000 visitors to visit the small south-central Pennsylvania borough of about 7,700 residents for the anniversary.  Reuters/Gary Cameron
