Blazoned in huge black letters across page one of the December 4, 1941, issue of the Chicago Tribune was the headline: F.D.R.’S WAR PLANS! The Times Herald, the Tribune ’s Washington, D.C., ally, carried a similarly fevered banner. In both papers Chesly Manly, the Tribune's Washington correspondent, revealed what President Franklin D. Roosevelt had repeatedly denied: that he was planning to lead the United States into war against Germany. The source of the reporter’s information was no less than a verbatim copy of Rainbow Five, the top-secret war plan drawn up at FDR’s order by the Joint Board of the Army and Navy.
