How to Study a Campaign

Lesson Overview

Lesson 01 explained why an officer studies military history, and Lessons 02 to 04 set out the principles of war that history has distilled. This lesson teaches the practical method: how to study a campaign so that it builds judgement instead of supplying false lessons.

Lesson 01 drew the distinction between studying for understanding and studying for fixed lessons, and warned of the false lesson and the misapplied analogy. It explained the right and wrong spirit of study. This lesson is its practical companion: the actual method that puts the right spirit into practice. Studying a campaign is a skill, not a matter of reading an account and forming impressions. There is a disciplined way to draw out a campaign's real value and avoid the errors careless reading produces, and the officer who learns it studies far more fruitfully.

By the end you will be able to explain why studying a campaign is a skill with a method rather than passive reading; work through that method, understanding the situation, following the decisions, examining the outcomes, and drawing lessons cautiously; explain the discipline of judging a campaign on its own terms rather than with hindsight; explain how to draw lessons that build judgement without the false lesson or the misapplied analogy; and apply the method to study a campaign for yourself.

Key Terms

• Studying a campaign: the disciplined examination of a historical operation, by a method, to draw out the understanding and judgement it can build.
• Understanding the situation: the first step, grasping the context as the commanders actually faced it, with the information and uncertainties they had, not with hindsight.
• Following the decisions: examining the commanders' decisions and their reasoning as the situation appeared to them at the time, so as to understand the deciding from the inside.
• The hindsight trap: judging a campaign by knowledge of how it turned out, which the commanders did not have, producing false and unfair lessons.
• Examining the outcomes: studying what happened and why, tracing results to their many causes without oversimplifying.
• Drawing lessons cautiously: extracting understanding while attentive to circumstances and wary of generalising, to build judgement without the false lesson.
• Relating to one's own situation: connecting the study to the principles of war and to one's own circumstances, with attention to the differences, to avoid the misapplied analogy.

Why studying a campaign is a skill with a method

It is tempting to suppose that studying military history means reading about battles and absorbing whatever impressions form, and that the more one reads the more one learns. Lesson 01 showed otherwise. Passive reading easily produces the false lessons and misapplied analogies that mislead, and it does not reliably build judgement, which is the real value of study.

The reason follows from Lesson 01's distinction. Studying for understanding does not happen automatically; it requires actively examining a campaign in a particular way: understanding the situation as the commanders faced it, following their reasoning, examining the outcomes and their causes, and drawing lessons cautiously. Without that method, reading slides into studying for fixed lessons, seizing on the simple memorable conclusion or the analogy that this campaign is just like a situation one faces.

So the method is what keeps study on the right path. The officer who has it knows what to look for and how to draw lessons safely; the officer without it may absorb some understanding but is as likely to absorb false lessons, and careless study of that kind can be worse than no study at all. The rest of this lesson teaches the method, because it is what turns reading about old battles into the active, judgement-building study Lesson 01 called for.

The method: understanding the situation and following the decisions

The method begins by understanding the situation as the commanders faced it, then following their decisions from the inside. These first two steps are the foundation, because they make the study an exercise in understanding rather than hindsight judgement.

Understanding the situation means grasping the context with the information and uncertainties the commanders had at the time, not with the knowledge of how things turned out. This is harder than it sounds. The natural tendency is to study a campaign already knowing the outcome and to read the whole of it in that light. To avoid this, the officer must reconstruct the situation as it appeared from inside: what the commanders knew and did not know, what uncertainties they faced, what the options looked like before the result was known. Only then can their decisions be understood rightly, because the decisions were made under that uncertainty, not in the clear light of a known outcome.

Following the decisions is the second step. Having reconstructed the situation, the officer asks of each major decision why the commanders decided as they did, what reasoning led them there, and what the options looked like from their position. This is the heart of judgement-building study. By asking not only what was decided but why, and what they themselves would have decided with the same information, the officer exercises their own judgement against the commanders' and builds it in the process. That engagement is what separates fruitful study from passive reading, which merely notes what happened.

   THE METHOD OF STUDYING A CAMPAIGN

   1. UNDERSTAND THE SITUATION as the commanders FACED it
      - their information, their uncertainties, BEFORE the outcome
      - set aside hindsight; enter the situation as it was
   2. FOLLOW THE DECISIONS from the inside
      - WHY did they decide as they did? what did the situation
        and options look like from their position?
      - ask: what would I have decided, with what they knew?
   3. EXAMINE THE OUTCOMES and their MANY causes
      - trace results to causes without oversimplifying
   4. DRAW LESSONS CAUTIOUSLY
      - attentive to circumstances; cautious about generalising
        (guards the FALSE LESSON)
   5. RELATE to the principles and to YOUR OWN situation
      - attending to the DIFFERENCES (guards the MISAPPLIED ANALOGY)

   AVOID THE HINDSIGHT TRAP throughout: judge the decision by what
   could be known WHEN it was made, not by how it turned out.

The hindsight trap and examining the outcomes

The greatest danger in studying a campaign is the hindsight trap, and the method must guard against it deliberately.

The hindsight trap is the error of judging a campaign by the knowledge of how it turned out, which the commanders did not have. Studying with the outcome already known, the officer is tempted to think the decisions that led to success were obviously right and those that led to failure obviously wrong, and to wonder how the commanders could have erred when the right course seems, in hindsight, so clear. This is unfair and misleading. The commanders decided under uncertainty, with incomplete information. A decision that led to failure may have been entirely sound given what could be known; one that led to success may have been a gamble that happened to pay off. Judging by outcome teaches that the courses which happened to succeed were right and those which failed were wrong, when the real measure is the quality of the deciding given what could be known.

The discipline, which the command course teaches in its own terms, is to judge each decision by what could be known when it was made, not by how it turned out. That requires the deliberate reconstruction of the situation the method begins with.

This shapes how the outcomes are examined. The officer does study what happened and how it came about, but traces outcomes to their actual causes, which are usually many, rather than oversimplifying into a single cause. The relationship between decisions and outcomes is examined honestly: how the decisions contributed, alongside chance, circumstance, and the decisions of others. Examined this way, the outcomes yield a true understanding of how the campaign came out as it did and what part the decisions played. Examined carelessly, by hindsight, they yield false lessons.

Drawing lessons and relating to one's own situation

The method closes with drawing lessons and relating the study to the officer's own situation. These steps must be done carefully, because they are where the false lesson and the misapplied analogy of Lesson 01 are either avoided or committed.

Drawing lessons cautiously means extracting the understanding the study offers while remaining attentive to circumstances and wary of generalising. A campaign does yield lessons, but a lesson that held in one situation may not hold in another. The lessons drawn rightly are usually about judgement, not fixed rules: not that some approach always works, but a richer grasp of how operations are decided, what tends to bear on outcomes, and how situations develop. That deepens judgement without handing the officer a false rule to apply mechanically.

Relating the study to one's own situation is the final step. The officer connects the campaign to the principles of war, seeing how it illustrates or complicates them, and to their own circumstances, considering how the understanding gained bears on operations they might conduct. This must be done with attention to the differences. The officer applies the understanding only so far as the situations are genuinely alike. Relate it carelessly, treating one's own situation as identical to the campaign's, and the result is the misapplied analogy.

Complete, the method is the disciplined way of studying a campaign that realises Lesson 01's studying-for-understanding and avoids its dangers. It is the officer's tool for a lifetime of study, and the more valuable for an officer of a young army whose own experience cannot supply the judgement that careful study of the wider history of war can.

In Practice: Studying a Campaign by the Method

An officer of the Royal Kaharagian Army sets out to study a historical campaign and applies the method rather than merely reading an account.

She begins by reconstructing the situation as the commanders faced it, setting aside her knowledge of how the campaign ended and grasping what they knew, what they did not, and what uncertainties they carried. Then she follows the decisions from the inside, asking of each major one why they decided as they did, what the options looked like from their position, and what she would have decided with the same information. Throughout, she guards against the hindsight trap: she judges each decision by what could be known when it was made, recognising that a decision leading to failure may have been sound and one leading to success may have been a gamble. She examines the outcomes carefully, tracing them to their many causes rather than to one.

Then she draws lessons cautiously, taking away a richer understanding of how operations are decided rather than a fixed rule, which guards against the false lesson. She relates the study to the principles of war and to her own circumstances, but attends to how her situation differs from the campaign's, which guards against the misapplied analogy. What she gains is real: her judgement is built by thinking through a hard situation from the inside. Contrast the officer who only reads the account: he judges by outcome, seizes on a simple lesson or a false analogy, and comes away with a misleading rule rather than built judgement.

Check Your Understanding

1. Explain why studying a campaign is a skill with a method, not merely reading and forming impressions, and why passive reading tends to slide into the false lessons and misapplied analogies Lesson 01 warned against.
2. Describe the first two steps of the method, understanding the situation as the commanders faced it and following the decisions from the inside. Why must the officer set aside the outcome, and what does it mean to follow a decision from the inside?
3. Explain the hindsight trap and the discipline against it. Then explain how lessons are drawn cautiously to avoid the false lesson, and how the study is related to one's own situation with attention to the differences to avoid the misapplied analogy.

Reflection (write a short paragraph): The greatest danger in studying the past is the hindsight trap: judging decisions by how they turned out rather than by what could be known when they were made. Think about how you judge decisions, your own and others'. Do you call the ones that worked good and the ones that failed bad, or do you judge whether they were sound given what could be known at the time? Be honest; judging by outcome is the natural and common way, and it is deeply unfair to the difficulty of deciding under uncertainty. Connect this to the command courses' teaching that your own decisions should be judged by what could be known when you made them. Then describe one way you could begin practising the discipline of judging decisions by the quality of the deciding rather than by the outcome.

Summary

• Studying a campaign is a skill with a method, not passive reading. Without a method, reading slides into the false lessons and misapplied analogies of Lesson 01 and does not reliably build judgement.
• The method begins by understanding the situation as the commanders faced it, with their information and uncertainties, not with hindsight. It then follows their decisions from the inside, asking why they decided as they did and what one would have decided oneself; exercising judgement against competent commanders' decisions is what builds it.
• The greatest danger is the hindsight trap: judging by knowledge of how it turned out. A decision that failed may have been sound, and one that succeeded may have been a lucky gamble. Judge decisions by what could be known when they were made, and trace outcomes to their many real causes.
• Lessons are drawn cautiously, attentive to circumstances and wary of universal rules, which guards the false lesson. The study is related to the principles of war and to one's own situation with attention to the differences, which guards the misapplied analogy.
• The complete method realises Lesson 01's studying-for-understanding and avoids its dangers. It applies the why-and-how of Lesson 01, draws on the principles of Lessons 02 to 04, applies the judge-by-what-could-be-known principle of Command, Mission Command, and Decision-Making (LDR 410), and feeds the enduring-and-changing study of Lesson 06.
