It is May of 1863 and the Civil War in North America has entered its third year. Facing a range of enemy threats, southern commander General Robert E. Lee proposes an invasion of the northern states to supply his army, relieve pressure on other imperilled fronts and to seek decisive victory on enemy territory that could end the war. Irish immigrant Daniel Ryan serves with his comrades of a Georgian regiment as the campaign unfolds, with Lee's army manoeuvring northwards through Virginia and across the Potomac River into Maryland and Pennsylvania, moving towards a fateful encounter with the Union army around the market town of Gettysburg.
