What Bernard Law Montgomery Can Teach Today’s Business Leaders

The general who won by refusing to hurry — and the cost that came with it

In August 1942, a newly arrived general did something that would have got most executives fired. Winston Churchill, the press, and an exhausted nation were all screaming for an attack in the Western Desert. Rommel was at the gates of Egypt. And Bernard Law Montgomery, three weeks into command of the Eighth Army, looked at the pressure bearing down on him and said, in effect: no, not yet, and don’t ask me again.

He waited two more months. When El Alamein finally came in October, it wasn’t a gamble — it was the methodical application of overwhelming, painstakingly rehearsed force, and it broke the back of the Afrika Korps. It was also the moment that made Montgomery’s reputation and, paradoxically, sowed the seed of his greatest failures to come.

That contradiction is what makes him worth studying. Monty was vain, abrasive, and a genuine nightmare to work alongside — Eisenhower spent half the war managing his ego rather than the enemy. But underneath the insufferable personality sat a leader who understood something most don’t: that the same instincts which make you great in one situation can quietly destroy you in another. Here’s what today’s business leaders can take from one of history’s most effective — and most exasperating — commanders.

1. His greatest strength and his worst failure were the same trait

Most leadership writing wants to hand you tidy virtues. Montgomery refuses to cooperate, and that’s precisely why he’s useful.

His defining quality was patience — a near-religious refusal to commit until the odds were stacked in his favour. At Alamein it was genius. He absorbed Churchill’s fury, built up his men and materiel, drilled his army until the plan was muscle memory, and won. Caution paid off spectacularly.

Then the war moved to Normandy, and the very same instinct turned against him. The methodical patience that had won the desert made him slow when speed mattered. After D-Day, his deliberate advance gave German forces time to regroup. At the Falaise Gap, hesitation helped let tens of thousands of enemy troops escape an encirclement that should have been decisive. The trait didn’t change. The situation did — and Montgomery couldn’t read the difference.

This is the lesson nobody puts on a motivational poster: your superpower is situational. The decisiveness that built your company can become recklessness at scale. The consensus-building that made you a beloved manager can become fatal indecision in a crisis. The frugality that kept you alive in the early years can starve you precisely when you need to spend.

In my opinion, the most dangerous leaders are not the ones with obvious weaknesses — those get found out quickly. They’re the ones who had one great strength, succeeded enormously because of it, and then applied it religiously to every situation regardless of whether it fit. Knowing when your instinct is wrong is harder, and rarer, than having good instincts in the first place.

2. He understood that morale is something you build, not something you order

When Montgomery took over the Eighth Army, it was a beaten force. It had retreated for months, lost faith in its leadership, and carried the particular cynicism of soldiers who’d been promised victory and handed defeat. His first act wasn’t a battle plan. It was a campaign to rebuild belief.

He made himself relentlessly visible — touring units, talking plainly to ordinary soldiers, ditching the remote-headquarters style of his predecessors. Before Alamein, he issued a personal message to be read to every man in the army, telling them what was coming and why it would succeed. It was theatre, and he knew it. It also worked, because exhausted people don’t need to be told to feel confident; they need to be given a reason to.

Then he did something cleverer still. Before the main offensive, he fought a smaller defensive battle at Alam Halfa — a deliberately winnable engagement, chosen in part to give a demoralised army the taste of a victory. A team that has won once will believe it can win again. He manufactured that first win on purpose.

The translation to business is direct, and it’s the opposite of how morale usually gets treated:

Cynicism is the default state of any workforce that’s been over-promised and under-delivered, and you cannot lecture people out of it. You earn your way out — by being visible rather than managing from behind a closed door, by explaining not just what people are doing but why and how their piece fits, and above all by engineering an early, achievable win when belief is low. You can have flawless processes and the best tooling money can buy; a demoralised team will still deliver mediocrity. Morale isn’t a soft extra. It’s an operational asset that compounds, and Montgomery treated it with the same seriousness he gave logistics.

3. He had the courage to be the only “no” in the room — and the flaw to overdo it

Montgomery was infuriatingly, immovably stubborn. He clashed with Eisenhower, sparred with Patton, and alienated nearly every peer he had. A great deal of this was naked ego. But some of it was the genuine moral courage to hold an unpopular line because he believed it was right — most famously his insistence on a single concentrated thrust into Germany against Eisenhower’s broad-front strategy.

He wasn’t always correct. Operation Market Garden — his plan, his push, his overreach — was a costly disaster that cost thousands of lives and proved the broad-front sceptics had a point. But the underlying principle survives the man’s poor judgement:

A leader who tells senior stakeholders only what they want to hear is failing at the actual job. Disagreement, voiced clearly and early, is a duty rather than a luxury. The discipline is in selection — constant objection is just noise, so you reserve your strong stands for the decisions that genuinely matter and let the rest go. And here is the half Montgomery never mastered: once a decision is made, even one you fought against, professional leadership means executing it wholeheartedly, not sulking and undermining it from the side.

I am always conscious that “disagree and commit” is far easier to print on a values poster than to live. Montgomery was a virtuoso at the disagreeing and hopeless at the committing. Most leaders are weak at both. The goal is to learn the whole sentence, not just the half that flatters your temperament.

4. His authority came from competence, not from rank

Whatever his sins as a colleague, no one ever accused Montgomery of not knowing his trade. He was an obsessive student of war, a meticulous trainer of troops, and a fanatic for detail. When he told you the plan would work, you believed him — not because he outranked you, but because it was visibly clear he had thought about it longer and harder than anyone else in the tent.

This matters more, not less, in a business world stuffed with confident generalists. People follow demonstrated expertise far more readily than they follow a job title. Montgomery’s victories weren’t the product of one man’s brilliance descending from on high; they were built on rehearsal and preparation drilled through every level of the army, so that competence was distributed rather than hoarded at the top. And his edge so often came from sweating the unglamorous things — the logistics, the training schedules, the contingency plans — that flashier commanders couldn’t be bothered with. The boring details win wars and quarters alike.

5. The lesson isn’t “be like Monty.” It’s “manage the Monty in yourself.”

Here’s the most honest part, and it’s a warning rather than a model. Montgomery’s ego and tactlessness did real damage to the Allied effort. His compulsive self-promotion soured a coalition that depended on cooperation; his inability to handle relationships created friction that a little grace would have dissolved. He was brilliant and genuinely costly, and the two are not separable.

So the takeaway runs the opposite way to the usual hero-worship:

A leader’s personality flaws don’t stay contained — they scale across an entire organisation. The sharp edge you got away with as an individual contributor becomes corrosive once a hundred people have to absorb it. The real organisational genius of the war wasn’t Montgomery; it was Eisenhower, who held a coalition of monstrous egos together long enough to win, and every strong leader needs that kind of steadying counterbalance nearby — someone whose temperament corrects for yours rather than amplifies it. Most of all, self-awareness is not a soft skill. Knowing what you’re bad at and actively compensating for it is the most adult thing a leader can do.

In my opinion, the leaders who cause the most lasting harm are rarely the incompetent ones. They’re the gifted ones who never learned to manage their own worst tendencies, and who mistook being right often for being right always.

Final Thoughts

Montgomery would have been a miserable person to report to, and he’d have been the first to tell you he was the cleverest man in the building. But his record holds a stubborn truth: effectiveness and likeability are different things, and the unglamorous virtues — preparation, morale, competence, conviction — usually outlast charisma and speed.

Don’t imitate the man. Steal his strengths and learn from the price of his flaws. Win the battle before you fight it, but stay alert to the moment your caution curdles into hesitation. Build your people’s belief on purpose. Know your trade better than anyone in the room. Hold your line when it matters and drop it when it doesn’t. And manage your own ego before it quietly manages everyone around you.

Get most of that right and you’ll be a better leader than the average. Get the last part right — the part Montgomery never did — and you’ll be a rare one.
