Courage Under Fire is the first book published about Operation Lamar Plain. After fifty years, the story of the renowned 101st Airborne's major offensive near Tam Ky, South Vietnam, remains largely unknown. Fighting at Tam Ky by the 1st Brigade began 15 May 1969 while the 101st's 3rd Brigade battled on Hamburger Hill. The political consequences of Hamburger Hill's high casualties caused Lamar Plain and its high casualties to remain classified and undisclosed. Decades later, the fighting at Tam Ky is mostly forgotten except by those who fought there. Sherwood's superb research of now declassified records uncovers how such a large battle could remain hidden and undisclosed. But that is not the heart of his story. His focus is on the courage and commitment of the young infantry soldiers who fought. This book uses actual battle records and eyewitness accounts to follow "Never Quit" Delta Company and its sister companies through continuous combat at Tam Ky. Delta Company's soldiers lived up to their motto despite increasing casualties, a tough enemy, harsh battlefield conditions, and loss of leaders. For all who fought at Tam Ky, their bravery and devotion to duty in an increasingly unpopular war is worthy to be remembered. With veterans of Tam Ky now growing older and fewer in number, it is past time to tell their story.
