During the ‘blackpowder era’ of firearms warfare, battle on land could be terrifying, with cannons and shells and musket-balls flying all over the place, and sure it was terrifying, but try doing it two hundred miles out in the middle of the ocean onboard a rocking, rolling wooden warship where defeat meant drowning in the waters of the Atlantic Ocean or the English Channel. These were the very real dangers faced by sailors and marines of the British Royal Navy during the period from 1792 until 1815, starting with the French Revolution and ending with the end of Napoleon’s conquest of Europe in the mid 1810s. What was battle like, out on the high seas back then and what happened during and after battle?

Ships of the Period

The first, all-metal ships did not appear until the mid 19th century. Before then, all vessels were made of wood. A warship of the 1790s, as typified by the ‘Man-o’-War’, was a multi-decked, three-masted affair with cannons and ropes and sails and all manner of other things onboard. Ships were wind-powered by massive sails and Mother Nature. The majority of the construction was of wood hammered onto wooden frames, with the gaps between the wood filled in with pitch (a black, tarry substance) and oakum, which was the broken-down fibres of old ropes. Oakum and the pitch were absorbent and sticky; contact with water made the hulls of the ships (mostly) watertight. While ships were able to deliver considerable firepower from either their starboard (right) or larboard (left, later changed to ‘port’) ‘batteries’ of guns (cannons), they were very vulnerable to attack from the front or back. The front, consisting of the bowsprit and the strengthened, curved, angled hull, was harder to destroy with cannonfire, but the stern of the ship, where the Great Cabin (also called the captain’s cabin) was located, was about as weak as soggy tissue-paper. With big, glass windows and few cannons, the stern was the weak-point of all vessels of the period.

Weaponry

Weapons to be found on ships during the Age of Sail consisted of bladed weapons such as boarding-axes, cutlasses, rapiers, daggers and bayonets, and firearms, such as pistols, muskets, rifles (what few that there would have been), and blunderbusses. There were also the various classes of large guns (cannons). These guns were massive, iron beasts which fired a variety of shot (ammunition) at any enemy ships. Firearms of this period were all single-shot, flintlock or matchlock weapons. They were slow to reload and inaccurate beyond a few hundred yards, for the cannons, and a few dozen yards, for smaller firearms.

Clearing for Action

If you were a captain onboard a British Man-o’-War during the Revolutionary or Napoleonic wars, and you saw an enemy, French warship sailing towards you, you had two options. To either prepare for battle, or to high-tail it out of there. When escape was impossible (due to being unable to pick up enough speed, or from being out-gunned), the order would be given to ‘clear for action’, or to ‘beat to quarters’.

‘Beating to quarters’ literally meant beating on a drum. The drummer set the pace of how fast everyone was expected to move. On the order to beat to quarters or to clear for action, everyone was expected to be in their places as soon as possible. The surgeon and his mate and the loblolly-boy were roused or set on alert to recieve injured sailors. Powder-monkeys (young boys, or even women!) were sent down to the powder-magazine at the bottom of the ship to fetch up gunpowder, and cannons were loaded and readied for action. The captain ordered his officers around to make sure that everything went smoothly. Officers were in charge of such things as organising the firing of the guns, relaying orders and helping to move away injured sailors. At the start of battle, the ship’s colours (national flag) were raised on one of the masts, to clearly identify the nationality of the ship (in case of mistaken identity) and valuables were put safely away.

The Heat of Battle

A real naval engagement was a terrifying thing to be in on. While in movies it looks glamourous and exciting, there was very little glamour about all the smoke and blood and guts and bullets whizzing around everywhere. As the two combatant ships drew up alongside each other, they would attempt to broadside (fire their full complement of guns on one side of the vessel) each other to cause the most damage. Although they were simple machines, naval cannons could pack a mighty punch. A single cannonball could blast a hole in a ship big enough for a man to crawl through. During combat, more sailors died from their injuries or infections, than actually died from being struck by cannon-blasts. In most cases, it was not the cannonball which killed you. It was the thousands of splinters of wood which the cannonball blasted aside as it smashed into the ship, that would slice into your body like knives and kill you through infection.

Dozens of cannons going off all at once produced amazing amounts of smoke, and the noise was literally deafening. Shouted orders were useless in such chaos, so instead, bosuns (boatswains), issued commands to the sailors using “bosun’s pipes”, long, metallic whistles which were capable of letting out piercing, shrill notes, which could be heard through the battle.

How fast a ship could fire its guns (and possibly win a battle), was dependent on many things. First, the skill of the gun-crew. Cannons were incredibly heavy firearms and they took an amazing amount of muscle to operate properly. Secondly, came the speed of the powder-monkeys. Gunpowder for the cannons was stored in the powder-magazine at the very bottom of the ship. The magazine was a large, copper-lined room, below the waterline, where gunpowder was stored in sacks and barrels. The walls were lined with copper because copper didn’t spark, like iron did. Powder-monkeys (usually young boys) had to be very fast in running the powder from the magazine up to the gun-deck as quickly as they could, in a relay fashion, slinging their powder-kegs from one to the other, back and forth, up and down.

Naval Surgery

Injuries from cannonfire could be horrific. Imagine having your arm blasted away by an 18-pound, solid iron cannonball, travelling fast enough to smash a hole in the side of a ship with bulkheads over a foot thick. Injured sailors were stretchered, carried or dragged from the gun-decks, to the infirmary at the back of the ship, near the Great Cabin. Here, the ship’s surgeon and the surgeon’s mate, together with the loblolly-boy (another assistant), had to look after and treat patients maimed by the battle upstairs. The treatments and surgery available, were mediocre at best and chances of survival or recovery varied wildly. Badly infected limbs would have to be amputated with a knife and hacksaw.

Bullets, shrapnel and other foreign bodies were removed from patients without anasthetic, the same for amputations. A surgeon was considered especially skilled if he could remove an arm or leg within two minutes. The only relief from the pain was lots of grog, or lots of laudanum (which is a mix of rum and opium). It was a kind of painkiller that dulled the pain and made the patient groggy, but it didn’t completely knock them out, so they could still feel a considerable level of pain. The surgeon’s quarters were often so drenched with blood, that he would pour sand (like what you find at the beach), onto the floorboards of his cabin and surgery, to soak up all the pints of blood which were spilling onto the floor and which caused a slipping-hazard.

Ships during the Napoleonic era would have had a surgeon and a mate. Note that: A surgeon. Not a doctor, a surgeon. Because so many of the injuries would have required amputation, it made more sense to have a surgeon onboard instead of a physician. Stephen Maturin in the “Aubrey & Maturin” series by Patrick O’Brian is a physician, and yet takes on the lesser position of surgeon onboard his friend’s ship, when he is in-search of a medical-man onboard his vessel.

The Weather Gage

One key factor in naval battles of the Age of Sail, was of course…the weather. Specifically the wind. How strong it was and in which direction it was blowing. Of course, the wind and its direction wasn’t the end-all of all battles, but it was certainly important. If the wind is blowing from north to south and there are two ships sailing side by side in an either easterly or westerly direction, the nothernmost ship is said to have the weather-gage. The direction of the wind means that it can easily sail away from an attacker, or sail southwards quickly, to engage the enemy. The southernmost ship, having to fight against the south-blowing winds, would have to trim (take in) sails to be able to move upwards to meet the attacking ship, which could, if it desired, sail away and disengage from the action.

Naval Warfare in the Age of Sail (Pt. II)

The second part of my two-part post on sea-battles during the Age of Sail (1500s-mid 1800s).

Cannons and their Ammunition

In the 18th and the first half of the 19th centuries, a warship’s main armaments, as typified by the frigate or Man-o’-War of the period, consisted of rows of cannons lined up on gun-decks inside the ship. While cannons such as these were simple to learn how to load and fire and operate in general, they were not easily worked, especially in the heat of battle, when a single cannon-blast might decide the outcome of an engagement. Cannons were massive, unwieldly, metallic beasts. Even the smallest of cannons, which fired roundshot of a weight of six pounds, could weigh several dozen pounds, not including the gun-carriage which the cannon rested on.

Firing a cannon was not a simple, one-man-presses-the-button operation back in the 1790s. It took skill, co-ordination and discipline to do it properly. Given their size and weight, it took several men to get a gun loaded and ready to fire. A typical gun-crew consisted of five men: a gun-captain, who was in charge of aiming and firing the gun, and four subordinates, who were in charge of loading the gun and running it out. When the enemy was sighted and the order was given to prepare the guns, this is how they were loaded:

1. The gun is charged with gunpowder, either loose gunpowder poured down the barrel with a special scoop, or a bag or pouch of gunpowder shoved down the barrel with a ramrod.

2. The gun is loaded with its ammunition. Depending on the size or type of ammo, it may need forcing down with a ramrod.

3. The charge and shot are wadded down with wadding (usually old, ripped up cloth), to prevent the ammunition from rolling out or moving unexpectedly.

4. The gun is primed and made ready to fire. On earlier cannons, this meant shoving a metal spike into the touch-hole at the top of the cannon-breech and feeding in either a burning match-cord (for a fuse), or a burning taper, to set off the charge. In later cannons, the gunlock (a type of flintlock firing-mechanism adapted for cannons) would be charged with powder and prepared to fire.

5. The gun is run out on its gun-carriage, pushing open the gun-port in the side of the ship. As cannons could weigh several hundred pounds, even when empty, running out a gun took a considerable amount of strength. Smaller guns could be pushed out by hand, but larger, 36 or 42-pounders would have to be winched out by ropes and pulleys, requiring the efforts of the entire, five-man gun-crew.

The order of ‘fire!’ is given. At this point, either the match-cord is lit, the taper is put to the touch-hole, or the lanyard operating the gunlock mechanism is pulled. The gunpowder explodes and propels the ammunition out of the muzzle, directly at the enemy. The recoil of the gun going off was significant. For safety reasons, sailors never stood directly behind a cannon, as the recoil could throw the gun back and either knock them over, or even worse, the wheels of the gun-carriage could roll over their shoes, crushing their feet! The ropes attached to the cannons didn’t just make it easier to run the cannons out, they controlled the powerful kick of the recoil, once the gun had discharged.

6. The gun is then swabbed with a sponge, to douse any embers inside the cannon, and the process from 1-5 is repeated all over again.

Cannons were simple to operate, even if they weren’t very easy to maneuver. But their simplicity-of-design allowed for a wide range of ammunition to be fired out of them, creating all kinds of hell for the enemy being fired at. While in theory, anything that could fit down the muzzle could be considered ammunition, there were several purposely-manufactured types of ammo which gun-crews used.

Roundshot. The classic, round, iron cannonball. These came in various sizes, the smallest being six pounds, the very largest being forty-two pounds. Roundshot was used to blast holes in the hulls of enemy ships. Roundshot was the mainstay of most battles, and the damage it could cause was considerable, to say the least. At thirty yards, roundshot from an 18-pounder cannon, could blast a hole straight through the hull of a ship three feet thick.

Hotshot. These days, someone who’s a ‘hotshot’ is someone who thinks he’s really skilled or effective at doing something. A little over 200 years ago, ‘hotshot’ was an actual type of ammunition! It is, as the name suggests, quite literally, ‘hot shot’. That is to say, a cannonball (roundshot), heated until it was smoking, red hot, before it was loaded into a cannon and fired at the enemy. Hotshot was both very effective and very dangerous, for obvious reasons. Hotshot required fires to heat the cannonballs red-hot. Onboard a sailing ship made of wood in the middle of the ocean, fire is the last thing you want. Hotshot was usually ‘baked’ on the galley stove, before being loaded into the cannon with a special scoop. Extra wadding was placed inside the cannon, to prevent the shot from setting off the gunpowder charge prematurely. Once loaded, the hotshot was fired just like any other cannonball, but with significantly more damage.

Once the ball had smashed through the enemy hull, it would roll around, too hot to touch. If it stopped anywhere for a long enough period of time, it would set the entire ship on fire, causing absolute chaos and distracting the enemy, probably long enough for you to blow the hell out of them.

Case-shot and grape-shot. Pretty-sounding names, aren’t they? Grape-shot. Sounds like a drink. Grape-shot and case-shot (more-or-less the same thing), consisted of several dozen musket-balls, chain-links, nails, bolts, shards of glass or whatever else you could find, shoved into a metal can (case) or into a cloth bag (grapeshot), and loaded into a cannon. When this was fired, it turned the cannon into one hell of a massive shotgun, spraying musket-balls (or other shrapnel) all over the place. It was particularly effective against groups of enemy soldiers or sailors, huddled together onshore or on the open deck of a ship.

Chainshot and bar-shot. Chainshot and bar-shot were two small cannonballs (or iron bars) linked by a length of chain and loaded into a cannon. Once fired out of the gun, the chain links unravelled, turning the shot into nothing short of a bolas from hell. Chainshot and bar-shot were particularly effective in slicing rigging (ropes), ripping sails to shreds, or dismasting an enemy ship. These whirring, whizzing necklaces of death could render a ship totally immovable once they had put the rigging and sails out of commission.

Explosive shell. The explosive shell was a hollow cannonball filled with gunpowder and stoppered with a match-cord fuse. Once the cannon was fired with this inside it, the ball would whizz through the air, the fuse (ignited by the gunpowder in the cannon) would burn until it reached the gunpowder inside the shell, blasting the thing open and sending metal everywhere.

Winning a Battle.

While cannons could pack a hell of a punch, it was a slow punch at best. To make the most use out of his cannons, the captain or commanding officer of the attacking ship, would be sure to target various weak-spots in the enemy ship, to get the biggest bang for his buck, so to speak. The four best places to shoot at were:

The rigging and the masts. Blowing them apart with chainshot and bar-shot rendered the enemy ship unable to move. You could now blow it to pieces as you wished.

The hull. Blowing holes in the enemy ship’s hull at, or below the waterline, would cause it to sink. Game over. While easy in theory, it took a fair bit of skill and timing to achieve successful destruction of a ship’s hull and make it sink. Most cannons could not be angled far down enough, to shoot into the hull on their own. They needed the help of the ship which they were mounted on. And the ship needed the help of Mother Nature.

On a ship rocking and rolling around at sea, if the ship was broadside to the waves, it would cause one side of the ship to be higher than the other, as it slid up and down the crests and troughs of each wave. Captains used this angling of their ships to their advantage, and would call out one of two orders, to fire ‘on the up-roll’ or ‘on the down-roll’. To fire on the ‘up-roll’ meant to fire when your side of the ship was angled upwards. Firing in this position meant that you could blow the masts off the enemy ship. On the other hand, firing on the ‘down-roll’ (when your side of the ship was angled downwards), meant that you could send your shot down, closer to the waterline, blasting holes in the enemy’s hull and sinking it.

The quarterdeck. The quarterdeck was the main deck of most ships and on smaller ships, it was also the gun-deck. Shooting at this area with case-shot and grape, would kill several dozen sailors, allowing you to board (if you wished) without fear of immediate attack.

The stern. Ships of the Napoleonic era (and before) were notoriously vulnerable at the stern, where there were few cannons to protect it, and where there were large windows, letting light into the captain’s cabin. This lack of protection allowed the attacking ship to destroy the enemy in absolutely horrific ways, if they could pull it off successfully. To successfully attack the stern of another frigate, you had to execute the maneuver known as ‘crossing the T’, where your long axis crossed the enemy’s short axis at the stern. You then had to carry out the firing-procedure known as ‘raking’. Raking fire was devastating, to say the least. It worked like this:

As each of your cannons passed the stern of the enemy, the gun-captain or officer in charge, would yell out the order: “Fire as you bear!”, which meant to discharge your cannon when you sailed past the enemy stern. This sent your shot smashing through the back windows of the ship and right down through the middle of it, destroying cannons, ripping through masts and killing and maiming enemy sailors, who had nowhere to run. Firing at the stern could also disable the enemy’s steering which meant they couldn’t come about (turn around) to face you, broadside-to-broadside, and give you a payback round. Firing at the stern could also sink the ship, leading to a decisive victory in your favour.

During battle, there were three basic outcomes: Sinking, burning or boarding.

Sinking a ship invovled blowing its hull to pieces and then leaving it (and the crew) to drown. Any sailors you picked up would become prisoners of war.

Burning a ship (either with hotshot or flaming torches) meant that it would turn into a massive, floating fireball, probably killing most people onboard.

Boarding a ship involved coming up alongside it, throwing grappling-hooks over the side and swinging over, onto the enemy ship. Boarding-parties (led by officers or the captain), could be ensured of heavy, close-quarters, hand-to-hand combat with enemy sailors. Weapons included muskets, bayonets, daggers, cutlasses and pistols. If you were lucky, you could beat the enemy and take his ship intact, as a prize (for which you could be handsomely and richly rewarded).

Winning a battle at sea was a great triumph for you and your men, and a great shame and dishonour to the enemy. An official surrender or defeat was recognised when the enemy captain surrendered his sword to either the attacking captain, or the attacking officer in command. Another way of surrendering was to ‘strike colours’. ‘Striking your colours’ was the action of lowering the naval flag of the country which your ship was a part of. Continuing to fight after the striking of colours was considered dishonourable, cowardly and above all…a serious crime.
