The true story of any conflict, from Gettysburg to Fallujah, is mostly lost forever, left behind on the battlefield. What remains is the stuff of history books - the letters and recollections of survivors. It is this material that seven Army historians are racing to preserve in Iraq. Judging the value of their work will fall to future academics, when their records are declassified. But until then, we have the accounts of participants in the project, like Lt. Col. John Boyd. Boyd talks with Brooke from Baghdad.
