Posts Tagged ‘Baron Antoine-Henri de Jomini’
After a delay of several weeks due to work obligations (reorganization), I’m starting up on Monday the course CIvil War Strategy and Tactics with great enthusiasm. Having seen the syllabus, I know that we begin with a discussion/debate of Jomini’s (pictured right) influence on the strategies employed by both sides during the Civil War. We read, (or in my case read again, as this was assigned in the course Great Military Philosophers), John Shy’s masterful essay on Jomini that appears in Makers of Modern Strategy from Machiavelli to the Nuclear Age. Do a search on my blog on the word Jomini (or click here as I’ve done it for you) and you may be as amazed as I was on the number of posts I’ve made about him.
See previous posts about the class below outlining the texts we’ll be using.
Class started on Monday. See post titled Next Course – Civil War Strategy and Tactics.
We’re beginning, and appropriately so, by exploring Jomini’s influence. Baron Antoine-Henri de Jomini. If you search for him on my blog, you’ll see quite a few references including a series I did titled “Jomini on the Nature of War.”

Returning to Baron Antoine de Jomini (right), I wanted to explore the extent to which his strategies influenced those who held leadership positions during the American Civil War. A modest survey of the literature revealed some disagreement.
Historian James L. Morrison, Jr. in his article “Educating the Civil War Generals: West Point, 1833 - 1861,″ pointed out that exposure to Jomini came during “Professor Dennis H. Mahan’s [pictured below] course, Civil and Military Engineering and the Science of War which all First Classmen studied daily.”[i]

But only nine hours were given to the study of the science of war and Morrison contends that this was entirely too brief an exposure to have had any lasting impact. That said, he acknowledges that some alumni of the military academy studied Jomini thoroughly including Beauregard, Lee, Halleck, and McClellan.
“…The same cannot be said for the great majority of their colleagues who had neither the opportunity nor the inclination to continue their strategic studies after graduation. Probably Sherman was more representative of the typical graduate when he denied that Jomini had affected his thoughts or actions in the war.” [ii]
I’ll discuss some additional viewpoints in the next post.
A word on Dennis H. Mahan. A military theorist in his own right, Mahan was instrumental in developing the engineering-focused curriculum at West Point. Some may recall that he was the father of naval strategist Admiral Alfred Thayer Mahan. The elder’s obituary, which appeared on September 17, 1871 in New York Times here, reveals that Professor Mahan committed suicide by jumping in the Hudson River from the deck of the steamboat Mary Powell in such a way that he was hit by the wheel. He was apparently despondant about being forced to retire. A sad end to a remarkable career. Professor Mahan’s memoir is available online here.

Jomini cautions that there are a number of other circumstances that can affect the “nature and conduct of war” including that…
- “a state may simply make war against another state
- a state may make war against several states in alliance with each other
- a state in alliance with another may make war upon a single enemy
- a state may be either the principal party or an auxiliary
- in the latter case a state may join in the struggle at its beginning or after it has commenced.
- the theater of war may be upon the soil of the enemy, upon that of an ally, or upon its own.
- if the war be one of invasions, it may be upon adjacent or distant territory: it may be prudent and cautious, or it may be bold and adventurous
- it may be a national war, either against ourselves or against the enemy
- the war may be a civil or a religious war.”[i]
He insists that war should always “be conducted according to the great principles of the art; but [that] great discretion must be exercised in the nature of the operations to be undertaken, which should depend upon the circumstances of the case.”[ii] “A regiment should always fight in nearly the same way; but commanding generals must be guided by circumstances and events.”[iii]
So the “principles of strategy are always the same,” but differences occur with the “political part of war, which is modified by the tone of communities, by localities, and by the characters of men at the head of states and armies.”[iv]
Jomini outlines these specific circumstances in a description of each type of war and the principles and rules to follow (or not follow) in every one. For example, in “Offensive Wars to Reclaim Rights,” he indicates that no rules can be laid down but to watch and to profit by every circumstance.[v] This leads to his conclusion that “war knows no rules.”[vi]
“Military science rests upon principle which can never be safely violated in the presence of an active and skillful enemy, while the moral and political part of war presents these variations. Plans of operations are made as circumstances may demand: to execute these plans, the great principles of war must be observed.”[vii]

“Principles were guides to action, not infallible mathematical calculations. The specific application of principles would vary with the thousand changing physical and psychological factors that made war ‘a great drama.’ Genius would defeat the military pendant, just as talent and experience would outdo the bumbling novice. But the principles themselves, whose truth is demonstrated by all military experience, could not be ignored without peril and, when followed, had ‘almost invariably’ (Presque en tout temps) brought victory.”[i]
Jomini’s arguments for “immutable ‘principle’ of war” rested on the concept of “lines of operation” by which he meant…
- “where an armed force fights,
- for what objective, and
- in what force relative to the total available military power of the state.”[ii]
He identified two types of lines of operation, those that are:
- deserts, and
- sheer distance through, over, and around which military operations must be conducted.”[iii]
- Also included in this category are man-made, permanent structures that constrict the conduct of warfare including: fortifications, military bases, political boundaries and road networks.[iv]
- Concerned exclusively with strategic choice about:
- where to fight,
- to what purpose,
- in what force, etc.[v]

Baron Antoine-Henri de Jomini, who was a product of the Napoleonic era, attempted to make warfare “scientific.”[i] According to Shy, this led him to reduce the study of war “…to a preoccupation with ‘strategy’ – a set of prescriptive techniques for military analysis and planning that has continued to dominate thinking on the subject.”[ii]
“…His general approach to the problem of war, abstracting it from its political and social context, emphasizing decision-making rules and operations results, turning warfare into a huge game of chess, has been surprisingly durable. Jomini more than Clausewitz, deserves the dubious title of founder of modern strategy.”[iii]
- “strategy is the key to warfare
- all strategy is controlled by invariable scientific principles
- these principles prescribe offensive action to mass forces against weaker enemy forces at some decisive point in strategy is to lead to victory.”[iv]
What is a decisive point?
One whose attack or capture would imperil or seriously weaken the enemy.[v]

Baron Antoine-Henri de Jomini
I’d like to begin a series of posts on Baron Antoine-Henri de Jomini. I had the opportunity to study Jomini along with other military strategists in a previous course, Great Military Philosophers which you can read more about on the courses page here, and wanted to come back to that material to dive in a bit deeper in. Why Jomini you might ask and what has he to do with the American Civil War? John Shy, in an excellent essay on Jomini that appears in one of my favorite books, Makers of Modern Strategy from Machieavelli to the Nuclear Age, wrote that “three names that stand out in the formative period of modern military thought: Napoleon, Clausewitz, and Jomini.”[i]
Everyone has heard of Napoleon. Many familiar with history have heard of the Prussian Carl von Clausevitz. But Jomini remains largely unknown outside of the military. And yet, Shy contends, Jomini’s “influence on both military theory and popular conceptions of warfare has been enormous.” [ii] His theories were known by militarists in many countries and certainly in the United States both before, during and after the American Civil War. More to come…
