The Battle of Gettysburg continues to capture the interest of people. The magnitude and scale of the battle draws thousands of visitors to the National Military Park each year. The area of greatest interest is the Union left flank. Devil’s Den, the Wheatfield, and Little Round Top are some of the most highly visited areas of that hallowed ground. It was here that the fiercest fighting took place. Defense of this area was given to General Dan Sickles. Sickles failed to follow orders and committed one of the greatest blunders of the war. Failure to secure Little Round Top was a costly error for the Army of the Potomac. Separating his corps from the army and creating a vulnerable salient, Sickles almost lost the Battle of Gettysburg. This book is an in-depth look at the life and military career of this highly controversial general and his actions at the Battle of Gettysburg.
