This is a print on demand edition of a hard to find publication. Hurricane Katrina, in Aug. 2005, was the costliest hurricane as well as one of the five deadliest storms in U.S. history. It caused extensive destruction along the Gulf coast from central Florida to Texas. Some 22,000 Active-Duty Army personnel assisted with relief-and-recovery operations in Mississippi and Louisiana. At the same time, all 50 states sent approx. 50,000 National Guard personnel to deal with the storm¿s aftermath. Because the media coverage of this disaster tended toward the sensational more than the analytical, many important stories remain to be told in a dispassionate manner. This study offers a dispassionate analysis of the Army¿s response to the natural disaster by providing a detailed account of the operations in Louisiana and Mississippi.
