"The present seems to be the most propitious time since the commencement of the war for the Confederate Army to enter Maryland," wrote Robert E. Lee following his army's stunning success at Second Manassas. Confederate armies advanced across a thousand mile front in the summer of 1862. The world watched anxiously--could the Confederacy achieve its independence? Reacting to the Army of Northern Virginia's trek across the Potomac River, George B. McClellan gathered the broken and scattered remnants of several Federal armies within Washington, D. C. to repel the invasion and expel the Confederates from Maryland. "Everything seems to indicate that they intend to hazard all upon the issue of the coming battle," he said of the invading force. Historians Robert Orrison and Kevin Pawlak trace the routes both armies traveled during the Maryland Campaign, ultimately coming to a climactic blow on the banks of Antietam Creek. That clash on September 17, 1862, to this day remains the bloodiest single day in American history. Following the popular Civil War Trails network, To Hazard All: A Guide to the Maryland Campaign, 1862 offers several day trip tours and visits many out-of-the-way sites related to the Maryland Campaign."--Provided by publisher.
