Ranger John Nicholas, Gettysburg National Military Park
While battles raged across American soil, another struggle unfolded in quiet rooms and diplomatic courts across the ocean. Join Ranger John Nicholas to explore how Union leaders worked to prevent foreign recognition of the Confederacy, and how President Lincoln’s shrewd diplomatic strategy—summed up in his phrase “One war at a time”—helped preserve the Union by keeping Europe out of America’s Civil War.
