Admiral Digby Museum, Digby


This cannon weighs 2112 kg.

The foundry marked this cannon's weight as 41 - 2 - 10,
meaning 41 hundredweight plus 2 quarters plus 10 pounds.
One hundredweight equalled 112 pounds, and one quarterweight
equalled 28 pounds. Thus this cannon weighs 4658 pounds.
One kilogram equals 2.205 pounds.

This cannon's weight works out to 2112 kilograms
(at the time of manufacture, not much changed now).

What's the big deal about cannons?


Nowadays, cannon and other forms of artillery from the 1700s and 1800s
are nothing more than quaint noise-makers. We see them only in the movies
and on TV, or at occasional demonstrations at historic sites.

In their day, cannons were the most powerful, far-reaching and fearsome
weapons available.

From clumsy beginnings in the mid-1300s, by the 1700s cannons had become
products of sophisticated technology that required advanced design and
manufacturing techniques available only in a few leading industrial countries.

Beginning in the 1600s, the technology of artillery was strongly influenced by
scientific developments in physics (force, pressure, gravity, acceleration),
mathematics (trajectories), chemistry (explosives) and metallurgy.

Cannons were complicated and expensive to manufacture and hazardous to use.
They could be operated only by highly-trained gunners – secretive men with
mysterious knowledge and skills and limited life expectancy.

Artillery could destroy walls of cities and fortresses. It could annihilate whole
bodies of troops instantly, and at a greater distance than any other weapon.
Kingdoms rose and fell by the power of saltpeter, sulfur, and charcoal,
as harnessed by cannons.

Dangerous to Use

The early cannons were more likely to kill the gunner
than the person he was shooting at.


Cannons were (and are) extremely dangerous to operate, because what makes a cannon do
its thing is a quantity of gunpowder, a powerful explosive. You had to use as much gunpowder
as you dared, to get more range. Unfortunately, if you used a bit too much gunpowder, the
cannon blew up. The problem was, when a cannon blew up the only people who knew how
much gunpowder had been used almost always were unable to tell anyone.

Just how much gunpowder could safely be used to charge a cannon? There was only one way
to find out — test-fire the cannon repeatedly, each time putting in a little more gunpowder,
keeping a written record and standing well away (at least a kilometre). When the cannon blew up
you knew how much was too much, and you could figure the safe charge to be something less.

The manufacture of cannons was not a highly-precise process. For each cannon produced,
the metallurgy and other important factors would vary. That is, every cannon was different to
some extent. When you measured the maximum charge by test-firing a cannon to destruction,
you then knew what was the safe amount of gunpowder for that cannon (the one that had been
destroyed). There was by no means a guarantee that other cannons like it (same material,
same design, same size, same manufacturer) would be able to handle a similar charge;
often they could but sometimes they couldn't.

Of course, the gunpowder itself was not exactly a reliably-uniform product, making the
firing of a cannon even more unpredictable. A safe quantity using one batch of gunpowder
might or might not be safe when another batch was available.

There were various ways a cannon could kill its crew. The most common problem was that
occasionally, when the cannon was fired, the cannon tube would explode near the breech
where the internal pressure was greatest. Another problem could occur during the loading
of a cannon, if something (such as a glowing ember deep in the gun from the previous firing,
or careless handling of the explosive charge) caused the propellant to explode prematurely.





Over the centuries, thousands of gunners and other soldiers died when a nearby cannon
exploded. And from time to time, prominent officials were killed by the explosion of a cannon.

A few examples:

On 3 August 1460, an exploding cannon killed King James II of Scotland during the siege of
Roxburgh Castle. The king, an enthusiastic believer in the use of innovative military technology,
was watching the operation of a new cannon and was standing too close when it blew up.

On 28 February 1844, the captain of the United States warship Princeton took U.S. President
John Tyler, several federal Cabinet officials, and about four hundred other dignitaries on a
Potomac cruise to demonstrate one of the ship's large guns. The cannon was fired several times
successfully, but the last time, about 3pm, the breech burst, killing the Secretary of State Abel
Parker Upshur, Secretary of the Navy Thomas Walker Gilmer, Senator David Gardiner,
Charge d'Affairs of the United States in Belgium Virgil Maxcy, and several others.

On 14 April 1861, Private Daniel Hough of the 1st U.S. Artillery was the first combat soldier
to die during the American Civil War. He was killed by an accidental explosion while the
garrison was firing a salute during the evacuation ceremonies at Fort Sumter on an island in
Charleston Harbor, South Carolina. On the 50th round of what was to have been a 100-gun
salute to the United States flag, the premature discharge of a cannon and the explosion of
a pile of cartridges resulted in the death of Private Hough. Another man, mortally wounded,
died several days later. The 50th round was the last.

On 19 April 1989, at sea 330 miles northeast of the island of Puerto Rico, 500 pounds (225 kg)
of high explosive propellant charge exploded in the open breech of the center 16-inch cannon in
gun Turret No. 2 on the USS Iowa, killing 47 crewmen within the turret. The Iowa, one of four
World War Two battleships taken out of mothballs during the Reagan arms buildup,
had been about to commence a day of test firing its guns, the world's largest naval weapons,
16-inch (40.6 cm) cannons that fired 2,700-pound (1225 kg) projectiles up to 24 miles (38 km).





[The following refers to the British Expeditionary Force (the British Army)
on the Western Front in France, 1914-1918]

...When the shell was fired from the gun, the pre-cocked detonator would be activated
inside the barrel of the gun or, perhaps, within a few feet of emerging from the barrel
with catastrophic results for the gun crew and anyone else in the vicinity. In 1916, during
the First Battle of the Somme, these 'prematures', as they were called, occurred in around
1 out of every 1,000 shells fired. In some divisions during the Somme Offensive, 500 rounds
were fired every 24 hours, thus, on average, one 'premature' was occurring every two days
or so. The effect on the morale of the gunners of this macabre game of 'Russian Roulette'
can be readily imagined...

More about exploding cannons: The Cannon is Broken! by Edwin R. Scollon
    http://www.historiclakes.org/vbrp/vbr5.htm





A cast-iron cannon is known to have exploded in Lunenburg County, Nova Scotia,
in 1897. It was located on Oxner's Hill, at the mouth of the LaHave River, and was
one of three cannons being fired in a Royal Salute probably at the time of
Queen Victoria's Diamond Jubilee, the sixtieth anniversary of her accession to
the throne in June 1837.

An Awesome Weapon


History of Cannon Technology by Steven A. Walton
    http://www.social.mtu.edu/faculty/sawalton/ch1.pdf

.mtu.edu — Michigan Technological University
One cannot help but be in awe and wonderment when a loaded cannon is fired –
the intense sound felt deep in one's stomach alone signals there is something
impressive happening. And cannon, after all, were designed to instill terror.
In fact most historians suggest that that was usually their only purpose on
the battlefield for the first 175 years or so of their existence...

Gunpowder first drew Europeans' attention in the thirteenth century, and
the first cannon appeared at the end of the first quarter of the fourteenth.
Most cannon of the fourteenth and fifteenth centuries were made out of
wrought iron staves forged together and hooped by more wrought iron,
in the same manner as coopers made barrels. Although cast bronze
guns apparently existed alongside wrought iron ones from the earliest
days of artillery, it was not until the mid-fifteenth century that bronze began to
clearly displace iron as the gunmetal of choice. Part of the hindrance was cost,
the copper in bronze being sometimes up to ten times as expensive as iron;
the other hindrance was the difficulty with casting bronze guns as large as the
smiths could forge iron guns...

Gunnery garnered or even demanded respect in its own time
for it was largely unnatural. Gunpowder was a mysterious substance,
often linked with the devil, whose effects were anything but expected
of a gray, lumpy powder. It was the alchemists' success story, creating
dramatic effects with the lightest touch of a smoldering match.
In essence, cannon demanded attention – and got it.

Cannons on Ships


Cannon and Carronades
...The early big guns were built up from strips of wrought iron, heated until they
glowed yellow,and then hammered to weld them together to form the barrel.
Rings of iron were forced over the barrel to reinforce it. Smaller guns were
cast in brass or bronze, using techniques used for centuries to produce statues.
In the 1500s the Dutch developed cast-iron cannon and the technique was
imported into England where the first iron cannon was cast in 1543...
Gunpowder produced vast amounts of thick smoke which
rapidly obscured the area of any naval battle.
A thick coating was also formed inside the barrel of the gun which
had to be scraped out...

    An 18 pounder long gun with a charge of 5 pounds of powder
was capable of penetrating nearly 2½ feet into oak
at a range of 400 yards, and over 1 foot at 1000 yards.
    [An 18 pounder long gun with a charge of 2.2kg of powder
was capable of penetrating about 70cm into oak
at a range of 400m, and over 30cm at 1000m.]

Gunpowder

There was much variation in the quality and
propellant effect of different batches of gunpowder.
