Mysore's Rockets Had Iron Bodies While Britain's Were Still Paper. Here Is What the Eyewitnesses Actually Wrote, and What They Didn't

Srirangapatna, the night of 6 February 1792

Picture a moonlit plain outside a river-island fortress. It is a little after ten at night. Three columns of British and East India Company troops are moving towards a fortified camp. Infantry only. No cannon. Their commander, Lord Cornwallis, is leading the centre column himself.

The island is Srirangapatna (ಶ್ರೀರಂಗಪಟ್ಟಣ), on the Kaveri, the capital of Tipu Sultan of Mysore. The British wrote it "Seringapatam".

Major Alexander Dirom, deputy adjutant general of the King's forces in India, was there. A year later he wrote it down.

Between ten and eleven, he says, the centre column ran into Mysore cavalry "that were coming with rocket boys to disturb our camp, as they had done on the preceding night." The horsemen galloped off. The rocket boys stayed. "They threw numberless rockets, that, like the flashes of distant lightning which precede a storm, were effectual only in declaring our approach." (Dirom 1793, p. 142)

Read that twice. In the middle of a night attack, a staff officer stops to describe the sky. And in the same breath he tells you the rockets did not stop the column. They only gave it away.

That is the Mysore rocket in one sentence. Frightening. Spectacular. Real. And, on the record, not a war-winner.

Seven numbers to hold before we start

• "A tube of iron, from six to twelve pounds weight." Munro's description of Hyder Ali's rockets, printed in London in 1789, on a bamboo "eight or ten feet long." (Munro 1789, p. 132)
• "Upwards of a thousand yards." Dirom's range for the rocket in his 1793 glossary: an iron tube "about a foot long, and an inch in diameter." (Dirom 1793, p. 295)
• 500 to 600 yards. What the largest rockets Congreve could buy in London managed when he tested them. (Congreve 1827, pp. 15–16)
• 1806. The spring Congreve began "forming them with iron cases instead of paper." (Congreve 1827, p. 17)
• 120 and 131. Two lines in a British return of Tipu's forces on 4 May 1799 that include rocket men, mixed with militia and infantry. (Beatson 1800, Appendix No. XXX, p. xcii)
• "Above 200 rockets." Congreve's count for Boulogne, 8 October 1806. A well-known modern lecture prints "above 2,000". (Congreve 1827, p. 18; Narasimha 1985, p. 14)
• More than 1,000. Corroded rockets taken out of a well in the fort at Nagara, Shivamogga district, in July 2018. (IANS, 28 July 2018; Archaeology, Nov/Dec 2018)

First, the words a beginner needs

Rocket. A tube of powder that burns at one end. Hot gas rushes out backwards, so the tube is pushed forwards. It carries its own push. A cannonball is thrown once and then coasts.

Casing. The tube that holds the powder. Weak, and it bursts. Strong, and you can pack the powder tighter for more push. This word is the hinge of the whole story.

Gunpowder. Saltpetre, charcoal and sulphur. The fuel of every rocket in this file.

Stick, or stalk. The long pole tied to the casing. It keeps the rocket pointing forwards, like the tail of a kite.

Yard. An old British measure, a little under a metre. A thousand yards is about 914 metres: nine football pitches end to end.

Tumbril. A two-wheeled cart carrying an army's gunpowder and shot. One spark, and everything near it goes up.

Tope. Anglo-Indian army word for a grove. "The Sultaunpettah tope" is the grove at Sultanpet, near Srirangapatna.

Anglo-Mysore Wars. Four wars between the rulers of Mysore (Hyder Ali, then his son Tipu Sultan) and the East India Company with its allies, the last ending in 1799.

Woolwich. The Royal Arsenal on the Thames, east of London. Its Royal Laboratory made ammunition. Congreve worked there.

Return. An army's head-count, written up as a table.

The claim we are testing

Here is the forward, more or less: "Tipu Sultan invented the war rocket. At Pollilur his rockets blew up the British army. The British took his rockets home, copied them, and that became the Congreve rocket."

I'll be honest. I wanted all of that to be true. An Indian inventor, a defeated empire, a twist. That wanting is exactly why I checked every layer.

1. Mysore armies used iron-cased war rockets in large numbers from at least 1780. True. Munro (1789) describes the iron tube and "some thousands of men"; Dirom (1793) and Beatson (1800) describe them in action.
2. They outperformed what Britain had. True, on Congreve's own numbers. He put Indian rockets at up to 1,000 yards. London's best managed 500 to 600.
3. Tipu invented the rocket. Myth. Rockets were used in China in 1232 CE, and Hyder Ali's own father commanded rocket men, says the scholar who studied this most closely.
4. Rockets won Pollilur. Unsupported as stated. The British eyewitness says the ammunition was "blown up or expended" and blames panicking camp followers. He never names rockets.
5. Britain copied Mysore rockets. Partly supported. Congreve names India as what he knew about. He never says he copied it.

Two true, one myth, one unsupported, one partly supported. And the true part is remarkable all by itself.

A tube of iron on a bamboo stalk

Innes Munro served in the Carnatic war that began in 1780. His letters, covering it to the peace of 1784, were printed in London in 1789. In Letter XI he describes Hyder Ali's army one arm at a time: quilted cavalry, matchlock men, pikemen with bamboo spears "eighteen or twenty feet long." (Munro 1789, pp. 131–132)

Then the rockets. This is the paragraph that matters most in this file:

"Hyder Ally also employs some thousands of men for throwing rockets. This is a missive weapon, and made in the same form as those used by schoolboys, with this difference, that the stalk is a thick bamboo, eight or ten feet long, which has a tube of iron, from six to twelve pounds weight, fixed to the end of it, in which the fuse and powder are placed." (Munro 1789, p. 132)

Plain words. "Those used by schoolboys" means the firework rocket every British child knew. Same shape. Two differences. The stick is a thick bamboo, taller than a man. And the body is iron: six to twelve pounds, roughly three to five and a half kilograms.

He goes on: "In wet weather, or marshy grounds, these are set off flying in the air, and will reach to the distance of a mile and a half; but upon dry grounds they are pointed horizontally, and bound in a very uncertain direction, often creating great damage, particularly amongst cavalry and ammunition tumbrils." (p. 132)

Two ways to fire. High, for distance. Or flat along hard ground, skipping and bouncing. And notice the targets: horses and powder carts.

One warning. "A mile and a half" is the biggest range in this file. Every other witness I read says about a thousand yards. Munro doesn't say he measured it.

Pollilur, 10 September 1780: did a rocket really decide it?

Now the battle every forward mentions.

On 20 July 1780, Munro writes, Hyder Ali's army came down into the Carnatic plains around Madras. (Munro 1789, pp. 133–134) The Company had a main army, and a detachment under Lieutenant-Colonel Baillie marching to join it. Hyder and Tipu set out to catch Baillie first.

Look at how Hyder covered his move. He left his campfires burning, "and two or three thousand horse and rocket-men kept hovering round our main army, in order to conceal his enterprise from us." (p. 151) The rocket men's first job here was deception. Keep the main army busy, and blind.

Next morning, near Pollilur, between Kanchipuram and Arakkonam, Baillie's detachment was surrounded. It formed "nearly in the form of an oblong square." They fought, Munro says, "until their whole ammunition had either been blown up or expended, which of course silenced the British artillery." (p. 154)

Listen carefully. "Blown up or expended." He doesn't say what blew it up. He doesn't say rocket.

And Munro wasn't in that square. He was with the main army, marching towards the firing and hearing it stop. (pp. 152–153) When he gives his own explanation, it is something else. Baillie's sepoys, he says, stood "the whole fire of the enemy, from seven in the morning until nine, when a fatal accident only broke their order": the camp followers breaking the ranks. (pp. 172–173)

The losses were terrible. Munro lists Lieutenant-Colonel Fletcher and twenty-nine European officers killed, with "one hundred and fifty-five European rank and file," and Baillie wounded and taken prisoner. (p. 157) A real and heavy Company defeat. Nobody disputes that.

So where does the rocket-and-tumbril story come from? From Mysore's own picture of the day. The battle was painted on the walls of Tipu's garden palace, the Daria Daulat Bagh, and in it an ammunition cart at one corner of Baillie's square is on fire. Roddam Narasimha, the aerospace scientist whose 1985 lecture is the classic study, wrote that this explosion, "touched off by Mysore rockets," is "thought to have been" a strong contributing cause. (Narasimha 1985, p. 2) Then, like a careful scholar, he adds that the Mysore historian C. Hayavadana Rao suggested the carts were set alight by French cannon. (p. 7)

Nobody I read was standing next to that cart.

If you ask me, rockets probably played a part at Pollilur. But "the rocket that won Pollilur" is built on top of the record, not written in it.

1792: "more alarm than damage"

Twelve years on, the Third Anglo-Mysore War. Cornwallis, with the Nizam of Hyderabad and the Marathas as allies, has reached Srirangapatna.

On 5 February 1792, Dirom says, Mysore horsemen rode alongside the march "throwing rockets on the flank of the line." (Dirom 1793, p. 127) That night Tipu "sent a party of his people with rockets to disturb the camps." Dirom's verdict: "But these useless weapons, creating more alarm than damage, were disregarded by our troops." (p. 129)

Useless. That's an enemy officer, with every reason to sound unimpressed. But the very next night the rocket boys were back, and he describes them again. (p. 142) You don't write about something twice in a dozen pages if it doesn't matter to you.

The best part of Dirom is his glossary, written for British readers who had never seen one:

"Rocket. A missile weapon, consisting of an iron tube of about a foot long, and an inch in diameter, fixed to a bamboo rod of ten or twelve feet long. The tube being filled with combustible composition, is set fire to, and, directed by the hand, flies like an arrow, to the distance of upwards of a thousand yards. Some of the rockets have a chamber, and burst like a shell; others, called the ground rockets, have a serpentine motion, and on striking the ground, rise again, and bound along till their force be spent." (Dirom 1793, p. 295)

Plain speech. Iron tube, a foot long, an inch across. Bamboo three to four metres. Over a thousand yards. Two types: one that burst like a shell, and a "ground rocket" that hit the earth, bounced, and snaked along until its push ran out. Think of a stone skipping on a lake, with the lake a field full of horses.

He ends the entry fairly. The rockets "exceedingly annoy the native cavalry in India, who move in great bodies; but are easily avoided, or seldom take effect against our troops, who are formed in lines of great extent, and no great depth." (p. 295) Deadly against bunched-up horsemen. Much less so against long thin lines.

1799: a grove, a signal, and a magazine

The last war, 1799. Our witness is Alexander Beatson, whose View of the Origin and Conduct of the War with Tippoo Sultaun was printed in London in 1800.

By early April, General Harris's army was camped near Srirangapatna, and Mysore "infantry and rocket-men" were so close "that many of the rockets, thrown from these places, fell amongst the tents." (Beatson 1800, p. 89) Imagine trying to sleep with that.

So on the evening of 5 April, two night attacks went out. One, the 33rd Regiment and the 2nd Bengal regiment, was under a colonel named Arthur Wellesley, the future Duke of Wellington. His job: clear the grove at Sultanpet. Beatson: Wellesley, "upon entering it, assailed on every side by a hot fire of musquetry and rockets," chose "to postpone the attack of the enemy's post, until a more favourable opportunity should offer." (p. 90)

Postpone. A very polite word for a night attack that went wrong. Next morning Harris ordered a bigger attack to clear the grove and the whole line of outposts. (p. 90)

Then 22 April. "At half past two on the morning of the 22d, the enemy's rocket-men, having got into the rear of General Stuart's encampment, threw a great number of rockets at the same instant." That volley was the signal. Straight after, about six thousand infantry and the French corps of Lally attacked, "under the command of Meer Golam Hussein, and Mahomed Hulleem, Meer Meerans." After several hours, Beatson says, they withdrew. (p. 108)

See what the rocket is doing now. A starting gun. Every rocket fired at once, from behind the enemy, so the whole Mysore force knows: now.

And then this. When the British breaching batteries opened, "a shot having struck a magazine of rockets in the fort, occasioned a dreadful explosion." (p. 123) A magazine of rockets. A whole storeroom of them.

On 4 May 1799 the fort was stormed, and Tipu Sultan was killed that day. (Narasimha 1985, p. 11)

Counting the rocket men, and a quote that changed years

How many rocket men did Mysore have? Online you'll see big numbers. Here is the one actual count I found.

After the fall of Srirangapatna, the British drew up a "Return of the Strength and Disposition of Tippoo Sultaun's Forces on the 4th of May, 1799." Beatson printed it. Inside the fort, 13,739 regular infantry. In the entrenchments, 8,100 more. Then field forces under named commanders. Under Qamar-ud-din Khan, one line reads: "Geesh, Rocket Boys, Infantry, &c. — 120." Under Purnaiah, the dewan or chief minister: "Geesh, Rockets, &c. — 131." (Beatson 1800, p. xcii) "Geesh," the same table explains, means "armed militia."

So listen carefully. This proves rocket men were a named part of Tipu's field forces on his last day, under two named commanders. It does not tell you how many there were, because each line lumps them with militia and infantry.

Narasimha's lecture gives the same two numbers, 120 and 131, as rocket units "in the Third Anglo-Mysore War of 1792." (Narasimha 1985, p. 6) The table I opened is dated 4 May 1799. Same numbers, different war. I'm going with the table. His bigger figures, about 1,200 rocket men under Hyder growing to about 5,000 under Tipu, I could not trace to a document. (p. 6) What I can give you is Munro's phrase from 1789: "some thousands of men." (Munro 1789, p. 132) Thousands, from a man who faced them. That's solid.

One more detective note. The same lecture quotes "one British observer" at the 1799 siege, via a 1966 rocketry history by Wernher von Braun and Frederick Ordway: the rockets "exceedingly annoy the native cavalry in India... but are easily avoided." (Narasimha 1985, p. 10) That is Dirom's glossary. Word for word. Printed in 1793. Narasimha quoted his source honestly, and even caught that source's date error for the 22 April attack. (p. 30) But a sentence from 1793 had quietly become an "observer" in 1799. This is why I go back to the first printed page.

Woolwich, 1804: Congreve tells his own story

Now we cross the ocean. William Congreve's father was Comptroller of the Royal Laboratory at Woolwich. (Narasimha 1985, p. 12) In 1827 the son, by then Major-General Sir William Congreve, published A Treatise on the General Principles, Powers, and Facility of Application of the Congreve Rocket System. It opens with how he began:

"In the year 1804 it first occurred to me, that, as the projectile force of the rocket is exerted without any re-action upon the point from which it is discharged, it might be successfully applied, both afloat and ashore, as a military engine..." (Congreve 1827, p. 15)

Plain words: a cannon kicks back, a rocket doesn't, so rockets could be fired from boats where cannon couldn't.

Two sentences later, India: "I knew that rockets were used for military purposes in India; but that their magnitude was inconsiderable, and their range not exceeding 1000 yards." (p. 15)

People quote half of that sentence. Yes, he names India. But in the same breath he calls its rockets "inconsiderable." He isn't saying "I'm copying them." He's saying "I know they exist, and I can go bigger."

Then he did what a good engineer does. He tested what he could get. "I immediately procured, at my own cost, the largest rockets I could get made in London, but found on trial that they were none of them capable of more than five or six hundred yards range." (pp. 15–16)

Stop there. The Indian rockets he called small went, by his own figure, up to a thousand yards. London's best, five or six hundred.

He improved them, without telling us how, from 600 yards to 1,500. Then, with Lord Chatham's permission, Woolwich built him a 6-pounder that he brought "to range full 2000 yards." (p. 16)

And now the sentence that, if you ask me, matters most in this file:

"In the spring of 1806, I conceived the plan, and obtained permission to proceed in making still larger rockets, and forming them with iron cases instead of paper." (Congreve 1827, p. 17)

Iron cases instead of paper. In 1806.

Put that beside Munro, 1789: "a tube of iron." Beside Dirom, 1793: "an iron tube." Seventeen years after Munro's book came out in London, Britain's leading rocket designer was only then moving from paper to iron.

Why did iron matter? A stronger case takes higher pressure, so the powder can be packed denser, for more push and more range, Narasimha explains. European rockets of the time had pasteboard cases. The Mysore tube was crude, hammered soft iron. But it was iron. (Narasimha 1985, p. 5)

Did Congreve take the idea of iron from Mysore? He doesn't say so. He doesn't deny it. The record proves the order of events: iron Mysore tubes in London print in 1789 and 1793, Congreve's iron cases in 1806. I draw the line between them dotted, not solid.

Boulogne, a missing zero, and rockets shipped back to India

Congreve tells the rest himself.

The first target was Boulogne, the French port holding Napoleon's invasion boats. The squadron gathered on 18 November 1805; the attack was set for the 21st. Then a gale blew up, the boats were recalled "without a rocket having been fired," and five of the ten launches were swamped. (Congreve 1827, pp. 16–17)

The second try came on 8 October 1806, with the new iron-cased rockets: "In about half an hour above 200 rockets were discharged... and in less than ten minutes after the first discharge, the town was discovered to be on fire." (p. 18)

Above 200. I checked the printed page itself, not just the scanned text. Narasimha's lecture, quoting the same sentence through von Braun and Ordway, says "above 2,000." (Narasimha 1985, p. 14) One extra zero, ten times the barrage. Small things like that turn events into legends. And Congreve is honest about the result: "What was the extent of the mischief effected cannot be known," and the boats he was aiming at mostly escaped. (p. 18)

Then Copenhagen, 1807. The Basque Roads and Walcheren, 1809. A Rocket Troop from Woolwich fought at Leipzig in 1813; Congreve says its men were allowed to wear "Leipsic" on their helmets. (pp. 18–19)

By 1814, in The Details of the Rocket System, his Plate 13 ran "from the eight-inch carcass or explosion Rocket, weighing nearly three hundred weight, to the six-pounder shell Rocket," the heaviest ranging "from 2,000 to 2,500 yards." (Congreve 1814, text to Plate 13) Three hundredweight is about 150 kilograms.

Here is Narasimha's real point. In 1799, he argues, the Mysore rocket was the better weapon. Within a few years the British effort was different in kind: tested propellants, standard designs, costed production, published tables. (Narasimha 1985, pp. 2, 17–18)

And one line almost nobody quotes. "I have also had the satisfaction of introducing this weapon into the service of the East India Company, and for that purpose, in 1817, I established a manufactory from which Rockets have from time to time been sent to India." (Congreve 1827, p. 19)

Read that slowly. The rocket that Britain first met as an Indian weapon was, within twenty years of Srirangapatna, being sent back to India as a British product.

A well in Shivamogga: the rockets come out of the ground

Now home. Karnataka, July 2018.

At Nagara (ನಗರ), in Shivamogga (ಶಿವಮೊಗ್ಗ) district, an old open well inside the fort, which reports also call the Bidanur (ಬಿದನೂರು) fort, was being dug out. Karnataka's Department of Archaeology, Museums and Heritage sent a team of fifteen archaeologists, excavators and labourers. It took three days. (IANS, 28 July 2018)

The assistant director who led it, R. Shejeshwara Nayaka, said the excavation "led to unearthing of over 1,000 corroded rockets," and that the mud "was smelling like gun powder." (IANS, 28 July 2018) To Archaeology magazine he called them "metallic cylinders filled with some powder," and said the team had "also found some equipment that might have been used for assembling or making them." The department's commissioner, G. Venkatesh, saw "a strong possibility that this site was used as a storage point or a factory for the rockets." (Archaeology, Nov/Dec 2018)

Now honest notes, because this is where forwards race ahead.

One: the size. The agency report says "23-26 cm or 12-14 inches." Those don't match: 23 to 26 centimetres is nine to ten inches. One figure is wrong.

Two: whose rockets? The excavators, says the magazine, date them to the 18th century, when Tipu ruled the region. But Nayaka himself told the agency some might be from the Keladi rulers before Hyder Ali, or the Wodeyars after Tipu. (IANS, 28 July 2018) "Tipu's rockets" is a working attribution.

Three: no site report. I found none. These are officials quoted by a news agency and a magazine.

Even so, look at the size. Nine or ten inches, give or take. Dirom's tube, 1793: "about a foot long." The two Mysore rockets described at the Royal Artillery Museum in Woolwich, as quoted by Narasimha from von Braun and Ordway, have casings 254 mm and 198 mm long. (Narasimha 1985, p. 5) A 1793 glossary, a London museum and a well in Shivamogga, all pointing at the same object: an iron tube about the length of your forearm.

Read the actual document

Don't take my word for it. Here is the earliest printed description of the Mysore rocket I found, as Munro wrote it, with only the old long "s" modernised:

"Hyder Ally also employs some thousands of men for throwing rockets. This is a missive weapon, and made in the same form as those used by schoolboys, with this difference, that the stalk is a thick bamboo, eight or ten feet long, which has a tube of iron, from six to twelve pounds weight, fixed to the end of it, in which the fuse and powder are placed. In wet weather, or marshy grounds, these are set off flying in the air, and will reach to the distance of a mile and a half; but upon dry grounds they are pointed horizontally, and bound in a very uncertain direction, often creating great damage, particularly amongst cavalry and ammunition tumbrils." — Innes Munro, A Narrative of the Military Operations on the Coromandel Coast (London, 1789), p. 132

In plain words: a firework shape, scaled up, with an iron body, a bamboo tail and thousands of men to fire it, aimed at horses and powder carts. And notice what he doesn't say. Not that Hyder invented it. Not that it won battles. He writes like a man describing a weapon he has learned to respect.

Ten lines, printed in London in 1789. Fifteen years before Congreve says the idea came to him.

The strongest case for the other side

I've told you what impresses me. Now the best case against the big story, in the record's own words.

One: the officers who faced them weren't that impressed. Dirom called them "useless weapons, creating more alarm than damage," and "easily avoided" by troops in long lines. (Dirom 1793, pp. 129, 295) Beatson records rockets thrown from the groves near Sultanpet "without effect" on 5 April 1799. (Beatson 1800, p. 87) Enemy witnesses, so discount them a little. But you can't keep only the witnesses you like.

Two: Mysore didn't invent the rocket. Narasimha, who admired the Mysore rocket, notes rockets in China in 1232 CE and in Europe in the 14th and 15th centuries, and says Hyder Ali's father already commanded fifty rocket men for the Nawab of Arcot. (Narasimha 1985, pp. 1, 4) Mysore's achievement was reviving the rocket as a serious weapon, in iron, at scale.

Three: Congreve never says he copied India. He gives India one sentence and calls its rockets "inconsiderable." (Congreve 1827, p. 15) The claim that captured Mysore cases were shipped to Britain for study rests, in Narasimha's lecture, on a 1978 popular history I could not open. (Narasimha 1985, p. 12)

Four: the rockets didn't decide the wars. Narasimha himself concludes they "were too inaccurate to tilt decisively the fortunes of battle in favour of Tipu." (Narasimha 1985, p. 2)

Five: the hardest one, from an Indian scientist. Narasimha ends by saying the British turned the idea into science, engineering and testing, a process "about which Indians of the 18th century had no clue whatever," and that it took India another 150 years to make rockets comparable to Britain's. (Narasimha 1985, pp. 19, 22) That's not a foreigner sneering. That's one of our own best engineers telling us the uncomfortable half.

What we could not prove

• Congreve's first book. A Concise Account of the Origin and Progress of the Rocket System is variously dated. I could not open it, so I used his 1827 Treatise. Narasimha dates the Concise Account to 1804 and has Congreve testing London rockets in "1801/2"; Congreve's own 1827 text says the idea came "in the year 1804." (Narasimha 1985, pp. 12–13; Congreve 1827, p. 15) I give Congreve's date.
• That captured Mysore rockets were studied at Woolwich by Congreve. Widely repeated. The sources Narasimha cites (Baker 1978; von Braun and Ordway 1966) I could not open.
• The two rockets "at Woolwich." I found no museum catalogue record to open for them.
• A rocket corps of 5,000. No primary count found.
• What set Baillie's tumbrils alight. No eyewitness I opened says.
• The Nagara rockets' size, date and owner. The report's figures conflict, and I found no excavation report.
• The "Battle of Guntur." Forwards show a Mysore rocket barrage at "Guntur"; an aviation encyclopaedia Narasimha read put one there in 1760. He searched the histories and found no such battle; Guntur was where Baillie's corps started its 1780 march, before Pollilur. (Narasimha 1985, pp. 29–30) I found nothing either. Telugu readers, I'm sorry: this one is a myth.

Why it still matters today

The material. The heart of this story isn't a sultan or a colonel. It's iron. A case strong enough to hold the push is the same simple idea every solid-fuel rocket still depends on. Mysore's armourers had it in the field before Britain's best designer did, and the enemy's own books say so.

The method. Narasimha's lecture is a warning, not a boast. Having the object first is not the same as owning the knowledge. Congreve tested, measured, published, and sold the result back to the East India Company. The lesson for us isn't "we did it first." It's "write it down, test it, keep going."

The habit of checking. In one small file, a 1793 glossary became a "1799 observer," 200 rockets became 2,000, a 1799 head-count moved to 1792, and a battle appeared at Guntur that no history records. None of it was dishonest. It's what happens when people quote the quote instead of the page.

Verdict

So what does the record prove?

That the armies of Hyder Ali and Tipu Sultan used iron-cased war rockets, in large numbers, through the wars of 1780 to 1799. British officers described them in print in 1789 and 1793: an iron tube, a long bamboo, a thousand yards or more. That London's best rockets in 1804 flew barely half as far, and that Britain's leading designer moved from paper to iron only in 1806. That rocket men served under Qamar-ud-din Khan and Purnaiah on Tipu's last day. And that a well in Shivamogga, in 2018, gave back more than a thousand of the things.

What it does not prove: that Tipu invented the rocket; that a rocket won Pollilur; that Britain simply copied Mysore; or the bigger numbers that float around online.

If you ask me, the honest version is better than the forward. A Deccan kingdom took an old idea and made it work in iron, at a scale that worried a European army, years before that army's engineers caught up. Then the other side did what Mysore didn't: turned it into a system. Both halves are true. Both are worth knowing.
