Friends of Padre Steve’s World,
I am traveling up to Gettysburg to lead a group of Army officers on a Staff Ride. It will be good. I will be doing my initially classes tonight at O’Rourke’s Irish Tavern in Gettysburg with these officers and then conducting the actual staff ride As such I am reposting a further edited section of my Gettysburg and Civil War text. This is the introduction section to what was my first chapter, which has grown so much that it will be its own book soon. I think that these words of introduction are important. I do hope that you enjoy.
Finite human beings find themselves bound by time and space, we live in the present, but not the present alone, but rather three worlds: one that is, one that was, and one that will be. Ernst Breisach wrote, “In theory we know these three worlds as separate concepts but we experience as inextricably linked and influencing each other in many ways. Every new and important discovery about the past changes how we think about the present and what we expect of the future; on the other hand every change in the conditions of the present and in the expectations of the future revises our perception of the past. In this complex context history is born ostensibly as reflection of the past; a reflection which is never isolated from the present and the future. History deals with human life as it “flows” through time.” 
Richard Evans wrote something in the preface to his book The Third Reich in History and Memory that those who study military history often forget. He noted: “Military history, as this volume shows, can be illuminating in itself, but also needs to be situated in a larger economic and cultural context. Wherever we look, at decision making at the top, or at the inventiveness and enterprise of second rank figures, wider contextual factors remained vital.”  Thus while this work is an examination of the Gettysburg campaign it is important to understand the various issues that were formative for the men who directed and fought the battle, as well as the vast continuum of often distant and seemingly events that come together at one time in the lives of the participants in any historic event.
One cannot understand the determination the determination of Robert E. Lee to maintain the offensive, the dogged persistence of Joshua Chamberlain or Strong Vincent to hold Little Round Top, what brought John Buford to McPherson’s Ridge, what motivated Daniel Sickles to move Third Corps to the Peach Orchard, and what motivated the men of Pickett’s division to advance to their death on Cemetery Ridge, without understanding the broader perspective of history, and how factors outside their direct military training and experience, such as culture, politics, economics, religion, sociology, ideology, life experience, and all of those factors shaped these men and their actions.
Likewise in order to understand the context of this battle, or for that matter any battle in any war, one has to understand the events, ever distant events which play a role in the battle. All too often those that delve into military history, or a particular battle see that as separate event, often disconnected from other historical events. But as historian Edward Steers Jr. correctly notes, history “does not exist in a series of isolated events like so many sound bites in a newscast. It is a continuum of seemingly unrelated and distant events that so often come together in one momentous collision of time.”  In the case of Gettysburg events like Lincoln’s publication of the Emancipation Proclamation, the failure of Confederate diplomacy to bring France or Great Britain into the war or at least to recognize the Confederacy, the failures of the Confederate armies in the West to maintain their hold on the Mississippi River, all play a crucial role in Robert E. Lee’s ill-advised decision to launch an invasion of Pennsylvania. Additionally, the loss of so many key leaders in the Army of Northern Virginia, especially that of Stonewall Jackson impacts how Lee manages the campaign, and shows up at numerous crucial points in the battle.
Another element that must be connected in order to understand the Battle of Gettysburg is the part that policy, strategy, war aims and operational doctrine played in the campaign of 1863 and how those influenced the decisions of participants before, during and after the campaign.
Finally, the Battle of Gettysburg cannot be looked at as a stand-alone event. What happens there as the Confederacy surges to and ebbs back from its “high water mark” influences the rest of the While the war would go on for nearly two more years, the Union victory at Gettysburg coupled with the victory of Grant at Vicksburg ensured that the Confederacy, no matter how hard it tried would not be able to gain its independence through military means.
Maybe even more importantly the story of Gettysburg is its influence today. The American Civil War was America’s greatest crisis. It was a crisis that that “has cast such a shadow over the relations between the North and the South that the nation’s identity and its subsequent history have been considerably influenced by it.” 
The Battle of Gettysburg itself is enshrined in American history and myth and is woven deeply into the story of the nation. In this narrative the Battle of Gettysburg is often different ways; in the North viewed as a victory that brings an end to the institution of slavery, and freedom for enslaved African Americans, and preserves the Union. In the South it is often part of the myth of the Noble Confederacy and the Lost Cause where the South was defeated by the Northern superiority in men and warmaking ability.
Yet in both cases, the truth is not so simple; in fact it is much more complex, and the truth is we are still in the process of learning from and interpreting the historical records of the events that led to the American Civil War, the war itself, and the aftermath. They are all connected and for that matter still influence Americans today more than any other era of our history. In fact James McPherson who is one of the nation’s preeminent scholars on the Civil War and Reconstruction wrote,
“I became convinced that I could not fully understand the issues of my own time unless I learned about their roots in the era of the Civil War: slavery and its abolition; the conflict between North and South; the struggle between state sovereignty and the federal government; the role of the government in social change and resistance to both government and social change. These issues are as salient and controversial today as they were in the 1960s, not to mention the 1860s.” 
The prolific American military historian Russel Weigley wrote of how the war, and in particular how the Battle of Gettysburg changed the American Republic.
“The Great Civil War gave birth to a new and different American Republic, whose nature is to be discovered less in the Declaration of Independence than in the Address Delivered at the Dedication of the National Cemetery at Gettysburg. The powerful new Republic shaped by the bayonets of the Union Army of the Civil War wears a badge less benign aspect than the older, original American Republic. But it also carries a larger potential to do good for “the proposition that all men are created equal” both at home and around the world.” 
Thus it is important for Americans to learn about the Battle of Gettysburg and the American Civil War, but not solely for its military significance, nor for clear cut answers or solutions. The fact is that “situations in history may resemble contemporary ones, but they are never exactly alike, and it is a foolish person who tries blindly to approach a purely historical solution to a contemporary problem. Wars resemble each other more than they resemble other human activities, but similarities can be exaggerated.”  As Michael Howard warned, “the differences brought about between one war and another by social or technological changes are immense, and an unintelligent study of military history which does not take into account these changes may quite easily be more dangerous than no study at all. Like the statesman, the soldier has to steer between the dangers of repeating the errors of the past because his is ignorant that they have been made, and of remaining bound by theories deduced from past history although changes in conditions have rendered these theories obsolete.”  The ideal that we reach for is to understand the Battle of Gettysburg and the American Civil War in context, which includes understanding what led to the war as well as the period of Reconstruction, and the post-Reconstruction era. In doing so we attempt to draw lessons from it without making the mistake of assuming that what we learn and know about them is immutable and thus not subject to change, for the past influences the present, even as the present and future will influence how we view and interpret the past.
