Mark Perry is a Washington-based author and reporter. His most recent book is Partners in Command. His forthcoming book (Basic Books, 2013) is a study of the relationship between President Franklin Roosevelt and General Douglas MacArthur.

In May 1934, reporters Drew Pearson and Robert Allen published a column in the Washington Herald accusing Army Chief of Staff Gen. Douglas MacArthur of "dictatorial, insubordinate, disloyal, mutinous and disrespectful" actions during the Bonus March, a peaceful veterans demonstration. MacArthur had broken up the protest by force -- using tanks commanded by Gen. George Patton -- back in July of 1932, an action that forever stained his reputation. Enraged by Pearson and Allen's claims, MacArthur sued them for $1.75 million. That scared the hell out of the columnists, who knew they'd have trouble proving their allegations. Here comes the good part.

Among MacArthur's enemies was Rep. Ross Collins, a powerful Mississippi Democrat -- drawl, jowls, slicked hair, the whole bit -- who controlled military appropriations and lived in the Chastleton Apartments on 16th Street and had seen MacArthur often in his building. Collins disliked MacArthur, and when he found out that Pearson and Allen were looking for something to hold against the general, he told them about the visits. Pearson and Allen followed up on Collins's tip and discovered that the 55-year old MacArthur was visiting Isabel Rosario Cooper, a 19-year old Filipino film star whom he'd brought with him from his last command in Manila and with whom he was having an affair.

Isabel was young and beautiful, and MacArthur showered her with gifts -- visiting her every day during his long lunches while he was chief of staff. But Isabel grew tired of the general and found his attention stifling, so she went to live with her brother in Baltimore, which is where Pearson and Allen found her. She then shared with the reporters what MacArthur had told her about Herbert Hoover (a "weakling," he said), and Franklin Roosevelt ("that cripple in the White House")....
