LTC Harry Tunnell's Red Devils is the history of one Soldier's and one unit's experience in Operation Iraqi Freedom. War must be studied from a variety of perspectives if one hopes to understand it and profit from that understanding. Like studies of grand strategy and operational histories, personal accounts of war are a critical aspect of understanding that immensely complex phenomenon. Using a journal which he kept during the war, then reflecting on his experiences while recovering from the wounds he suffered and while at student at the National War College, LTC Tunnell tells the story of the 1st Battalion, 508th Parachute Infantry Regiment in Northern Iraq. The story of the Red Devils covers that crucial period of time from early 2003 when the Army prepared for war, through the end of so called 'major combat operations, ' and into the start of the insurgency and counterinsurgency which goes on to this day. This is not a comprehensive, polished historical analysis, but a first-hand account of Operation Iraqi Freedom's earliest period. Red Devils represents one man's attempt to make sense of his and his unit's experiences in Iraq. It represents only a small part of the history of many units and individuals which have taken part in, and continue to take part in, the defining military campaign of our time. We hope this study will be useful as readers attempt understand that complex campaign
