Ruben Gallego of Arizona is correcting a passage about a deadly Iraq War battle that falsely alleged that Ellen Knickmeyer, the Baghdad bureau chief for the Washington Post at the time and now with The Associated Press, had reported his whole platoon had been lost.“They Called Us ‘Lucky’: The Life and Afterlife of the Iraq War’s Hardest Hit Unit,” co-written by Gallego and Jim DeFelice, was published last November by the HarperCollins Publishers imprint William Morrow.
