'The Danger Paradox' – Thomas Cochrane’s Guide to War

Thomas Cochrane is one of the great figures in British military history. He began his career in the Royal Navy in 1793 and became a national celebrity during the Napoleonic Wars, achieving a string of astonishing victories.

The most famous of these came in 1809 when he destroyed much of the French Atlantic Fleet in an attack with fireships and explosion vessels at Basque Roads.

Later Cochrane gained global renown for his revolutionary feats in South America, where he fought for the Chileans and the Brazilians against the Spanish and Portuguese Empires.

Here Peter Moore, the author of the new biography, A Dangerous Game: Thomas Cochrane's Life on the Edge, examines what made this Scottish sailor such a unique and successful figure in military history.

When he was a young lieutenant, Thomas Cochrane met Horatio Nelson in Palermo. Awed as most were who came into the presence of the hero of St Vincent and the Nile, Cochrane remembered Nelson imparting a lucent piece of military wisdom: ‘Never mind manoeuvres, always go at them.’

The unfussiness of Nelson’s maxim appealed to Cochrane’s pragmatic nature, and in the blunt analysis of his own fighting career some have suggested that there was little more to it than that.

But, really, Cochrane’s approach to combat was distinct and highly sophisticated. ‘In war,’ he once explained, ‘much depends upon the resources of a man’s own mind and these he employs when the pressure of the moment demands them.’

Cochrane had a highly structured approach to war. He always thought first about ‘objectives’ and did not take a step more until these had been defined. Once they had, he invariably assumed the role of protagonist, believing that wresting the upper hand as quickly as possible was paramount. It was at this juncture that he was at his most dangerous and vulnerable. Determined to seize control, he would often risk all in a lightning assault.

While an early attack was characteristic of Cochrane, it did not exclude preparation. Throughout his years as a frigate captain in the Royal Navy, total vigilance was demanded from the boys at the masthead. When Cochrane expanded his range from coastal shipping to inland targets in 1806 – telegraph stations, forts, batteries – he made it a habit to know the geography before he made any move.

‘I vouched for these facts with my own eyes’ was a typical refrain. Often he would ask the ship’s master to accompany him in a boat with the sounding lead. When there was no scope for this, Cochrane would sit in the netting, studying the water as it rushed beneath.

As well as comprehending his environment, Cochrane was preoccupied with weaponry. What weight of broadside could be fired? How could this number be augmented? Was there a way of making it more deadly?

But Cochrane’s approach to war was not all mechanical industry. He had a feel for its emotional aspects too. He liked to launch his attacks in twilight or total darkness. ‘Night, doubt and fear are powerful magicians,’ as one of his friends wrote.

When a daylight assault was necessary there was a range of other tricks that could be played. At various times he flew false flags, performed feints and disguised his paintwork. On the confused seascape every second mattered and a clever disguise could buy a minute. Cochrane liked to shapeshift, to intimidate and to lure. He knew, by instinct, when to show his hand.

Many still thought him reckless. He refuted this. ‘Rashness, though often imputed to me, forms no part of my composition,’ he defended himself. ‘There is a rashness without calculation of consequence; but with that calculation, well-founded, it is no longer rashness.’

Contained in this tangle is Cochrane’s appreciation of the ‘danger paradox’. This was an understanding that the most perilous course of action might be the safest, as it was the course an opponent least anticipated. Rushing towards the Spanish xebec frigate El Gamo in his famous Action of 6 May 1801 or offering a fight to the far more powerful French frigate Minerve in 1806 in Basque Roads are examples of this.

Any audacious strategy, of course, depended on the conviction of his men. Were they to refuse to follow, disaster would inevitably ensue. It was here that Cochrane excelled. He had an affinity with those he sailed with. He knew how to speak to them, to lure them, to excite them and to stir them into life.

These were the magical qualities of leadership – difficult to define but powerfully present. Once, when a party of the Impérieuse’s sailors returned from an aborted attempt to blow up a shore battery, Cochrane asked them whether it was an impossible task. ‘No, my Lord,’ came the answer, ‘’tis not impossible. We can do it if you will go.’ Cochrane then led his men in a second attempt, and the battery was successfully stormed.

Once fighting had begun, Cochrane was always determined to see it through. Losing heart brought more miseries than consolations. While this was a rule, he nonetheless retained the ability to think clearly during combat. Some might call it intuition, others an inner voice, but Cochrane possessed some guiding instinct that protected him at dangerous moments.

This showed itself significantly on 30 November 1808, when he sensed that an attack on Fort Trinidad in Catalunya was imminent. Cochrane was then in the unusual position of leading a defensive force and at dawn that day he was stood beside a young Frederick Marryat scanning the valley in front of them.

Sailors talked often about the loom of a land when they were at sea – perceiving its appearance before they could see it. That morning there was something similar, ‘something unusual in the valley'. Cochrane ‘listened a moment', remembered Marryat, looked attentively with his night-glass and exclaimed, in his firm but confidential voice, ‘To arms! – they are coming!’

Cochrane's foresight on this occasion doubtless saved many lives. The attack that came towards them involved a whole company of French grenadiers, two of carabiniers and four of an Italian regiment – an estimated thousand men. The speed of his thinking allowed those inside the fort to respond just in time.

It was owing to such instincts that, especially in his early career, the casualty rate among Cochrane’s men was strikingly low. Many of his most astonishing fights – the capture of El Gamo for instance – resulted in only the deaths or one or two. During his Royal Navy days a Lieutenant Caulfield was the only one of his officers to be killed in action.

One contemporary declared that he admired nothing more in Cochrane ‘than the care he took of the preservation of his people. Bold and adventurous as he was, no unnecessary exposure of life was ever permitted under his command. Every circumstance was anticipated, every precaution against surprise was taken, every provision for success was made.’

Cochrane approached war as a skilled professional approached their trade. He took pleasure in the performances of other master craftsmen, like Captain Collett of the Minerve who fought him hard and with great skill in 1806. He recalled a curious episode at the end of that engagement when, after the firing had stopped, he and Collett locked eyes for a moment.

Collett was standing on a gun, Cochrane wrote, ‘with as much sang-froid as though we had been firing a salute’. The captains, who had spent the past hour and a half attempting to kill each other, stared at each other. At length Collett 'raised his hat, with all the politeness of a Frenchman of the old school, and bowed to me, a compliment which I returned,’ wrote Cochrane.

To some Cochrane's approach to war might look like a simple matter of dashing towards victory, but a whole apparatus of thought and planning lay beneath that decisive move.

Patrick O’Brian, who studied Cochrane’s approach to war very carefully indeed, left Jack Aubrey to explain it best. ‘War is nine parts boredom,’ he said, ‘and we grow used to it in the service. But the last hour makes up for all, believe me' •

This is surely the definitive account of this extraordinary man. Moore does not shy away from the dark side [of Cochrane]… but in doing so he makes the story only more compelling… compulsively readable… I have not enjoyed a book more for a long time – George Owers ― The Times

A gripping new biography ... exciting to read. A Dangerous Game must surely be the last word on a man who was once a national hero – Adrian Tinniswood ― The Literary Review

The astonishing true story of Thomas Cochrane – naval hero, political radical and inspiration for Patrick O’Brian’s Jack Aubrey – whose audacity at sea, scandals on land and battles across empires make for a tale as thrilling as any novel.

Cochrane’s life was even more remarkable than the fiction it inspired. A hero of the Napoleonic Wars, known for destroying the French Atlantic fleet in one explosive attack, he was an equally aggressive force in British politics as the radical MP for Westminster.

Cochrane’s fortunes turned in 1814, when he was convicted of a fraud on the Stock Exchange. After escaping from prison, he later reinvented himself as a revolutionary admiral, helping the Chileans, Peruvians, Brazilians and Greeks in their struggles for independence.

In A Dangerous Game, the Sunday Times-bestselling historian Peter Moore draws on newly uncovered materials to bring Cochrane vividly to life. Bold, rebellious and uncompromising, he saw the world as a contest to be won – at sea, in politics, even in scandal – and played it more dangerously than any man of his era.
