Catapults in Gorean battle

Catapults on city walls, often roped down to keep in place
If not roped down, the catapults can spin about or fling themselves off the wall
Easier to manage on softer surfaces where wheels can dig in
We could hear, too, from time to time, the sound of the kick and rattle, and vibration of cordage, of a catapult above us, on the walls. They are often roped down. Otherwise they can radically change their position, spinning half about, or even, literally, flinging themselves back off the walkway. They are easier to manage on softer surfaces, where the wheels can be dug in.

Catapults moved into place by tarn teams
On the tenth day of the siege small engines, such as covered catapults and ballistae, were flown across the ditches by tarn teams and soon were engaged in artillery duels with the engines mounted on the walls of Ar. Simultaneously, exposed chains of siege slaves began to move the stake lines forward. After some four days of bombardment, which probably had small effect, if any, the first assault was mounted.

Catapults mounted on wheeled platforms
Can fire over draft aninmals
Firing tubs of burning pitch and flaming naphtha
Firing siege javelins and giant boulders
He then utilized, for the first time in Gorean field warfare, first at Rovere, and later at Kargash, mobile siege equipment, catapults mounted on wheeled platforms, which could fire over the heads of the draft animals. From these engines, hitherto employed only in siege warfare, now became a startling and devastating new weapon, in effect, a field artillery, tubs of burning pitch and flaming naphtha, and siege javelins, and giant boulders, fell in shattering torrents upon the immobilized squares. The shield shed was broken. The missiles of archers rained upon the confused, hapless defenders. Even mobile siege towers, pushed from within by straining tharlarion, pressing their weight against prepared harnesses, trundled toward them, their bulwarks swarming with archers and javelin men. The squares were broken. Then again the ponderous, earthshaking, bellowing, grunting, trampling, tharlarion ground cavalry charged, this time breaking through the walls like dried straw, followed by waves of screaming, heavily armed spearmen. The ranks of the enemy then irremediably broke. The air howled with panic. Rout was upon them. Spears and shields were cast away that men might flee the more rapidly. There was little left to be done. It would be the cavalries which would attend to the fugitives.

“I fear for Ar’s Station,” said the porter.
“How is that?” I asked.
“I do not think she can long hold out,” he said. “The attackers are numerous.
The defenders are thinned. The walls are weakened. New breaches are made daily. In places they are being mined. Fires have occurred in the city, from saboteurs, from fire javelins, from flame baskets catapulted over the walls. There is starvation in the city. If the forces of Ar do not soon raise the siege, I think she must succumb.”

Great stones, some as much as a thousand pounds in weight are catapulted
I did not think the fellow with the rope really wanted to approach the far wall, the outside wall, or weather wall, too closely. From time to time we could hear, and sometimes feel, through the floor, the impact of the Cosian projectiles, the great stones, some of which would weigh a thousand pounds or more, flung by mighty catapults, some the size of houses. We could hear, too, as though far off, the rhythmical shock of the battering ram at the gate, where men toiled at the hundred ropes, beneath the long shedlike roof which protected them and the ram.

“The Cosians must not bring their catapults into action, at this range,” she said.
“Why not?” I asked.
“The people,” she said. “The crowding. It would be terrible.”
“I see,” I said.
“Surely they would not do so,” she said.
“I would conjecture that the engines will be in place by morning,” I said.
“But they will not use them!” she said.
“I would expect them to do so,” I said, “with stones, and oil, and javelins.”

Catapulting javelins, burning pitch, fiery rocks and crossbow quarrels
On the other hand, whereas the round ships do not carry rams and are much slower and less maneuverable than the long ships, they are not inconsequential in a naval battle, for their deck areas and deck castles can accommodate springals, small catapults, and chain-slings onagers, not to mention numerous bowmen, all of which can provide a most discouraging and vicious barrage, consisting normally of javelins, burning pitch, fiery rocks and crossbow quarrels. A war ship going into battle, incidentally, always takes its mast down and stores its sail below decks. The bulwarks and deck of the ship are often covered with wet hides.

Two catapults on this tarn ship
Tarn ships are painted in a variety of colors; the Dorna, of course, was green.
Besides her stem and stern castles the Dorna carried two movable turrets amidships, each about twenty feet high. She also carried, on leather-cushioned, swivel mounts, two light catapults, two chain-sling onagers, and eight springals.
Raiders

Men keep up a heavy fire with catapults
Meanwhile, of course, the numerous bowmen, and the men at the springals, catapults and onagers would be keeping up a heavy fire, the more devastating, the closer the distance. It was my hope that my round ships, with their large, free crews, and their artillery, and their boarding potentialities, might be a match for even heavy-class tarn ships.
Raiders

Fire missile launched from catapult sets a ship aflame
I saw a fin, long and white, suddenly cut the water. A ship passed near us, but it was one which flew the flag of Port Kar, a light galley. It did not pause for us. I saw a trail of smoke looping through the sky as a fire missile was launched from a ship’s catapult. Far to our left we saw a galley aflame. It was one of Cos.

Catapulting canisters of flaming pitch
Outside and above decks we could hear shouting, and the sound of sprung ropes, as the canisters of flaming pitch were lofted from the deck catapults.

Clay globes filled with flaming oil catapulted
I felt distinctly uneasy that the masts could not be lowered. How vulnerable seemed the ship, the masts high, with their sloping yards and billowing canvas. There was a light catapult forward, but it had not yet been erected. If Ulafi had torch arrows they were not in evidence. Too, the fire pans had not been kindled for dipping the arrows, nor had a fire been kindled beneath the oil kettle, for filling the clay globes with flaming oil, to be cast in looping trajectories from the catapult forward. If onagri or springals lay unassembled in the hold they were not yet being brought to the deck.
Explorers

A clay globe, shattering, of burning pitch struck across our deck. Another fell hissing into the water off our starboard side. Our own catapults returned fire, with pitch and stones. We extinguished the fire with sand.

A heavy stone from a catapult struck through a deck
I heard water rushing into the other vessel, a rapid, heavy sound. She was stove in. A heavy stone, from some catapult, struck down through the deck near me, fired doubtless from some other galley. A javelin, tarred and flaming, snapped from some springal, thudded into the stem castle.

Catapult on large rotating mount
Ropes are four inches in diameter
The catapult on the enemy's stern castle had broken loose from its large, rotating mount. Its ropage hung down, dangling in the wind. The strands seemed narrow, from the distance from which I viewed them. The largest, however, would be some four inches in diameter. I saw a man leap from the stern castle into the water.

Catapulting stones from the ships
"Catapults!" called Callimachus.
Two stones looped into the air and then, gracefully, began their descent toward one of the pirate ships.
Huge spumes of water rose into the air as the great rocks plunged into the Vosk
Guardsman

We sped down the deck. The ship shuddered as the great catapult loosed a stone which shattered into the rowing frame on the port side of the Tina.
Guardsman

A mighty rock, then, suddenly, not more than ten feet from my bench, plummeted through our deck, splintering the wood upward, exploding it upward, in a shower of sharpened fragments. We had not even seen from whence the stone came. A looping bowl of flaming pitch traced its trajectory off our starboard bow and fell into the water.
"Stroke!" called the oar master.
We began to nose our way among flaming and shattered ships.
Our benches vibrated as our own major catapult hurled a stone skyward.
Guardsman

Catapulting smoke bombs as signals
A smoke bomb, trailing smoke, was lofted upward from a catapult on one of the lead ships. It arched gracefully upward and then fell into the marshes lining the channel.
"Return the signal," said Callimachus.
In moments an answering smoke bomb, from a catapult on the walls, describing its graceful parabola, ascended and then seemed to pause, and then looped downward, to splash into the marshes.
Guardsman

"Fire bombs!" called Callimachus. "Signal our fellows in the marshes! Let the attack flags be raised!" There was a cheer upon the walls. Men rose up on the walls, lighting fuses of oil-soaked rags, thrust into oil-filled, clay vessels; a smoke bomb, trailing red smoke, was lofted from a wall catapult high over the marshes. Red attack flags, torn by the wind, snapped on their lines. Vessels of clay, spreading broad sheets of flaming oil, shattered on the decks of the vessels in the yard. Soldiers of Ar's Station, emerging from the marshes on the left and right, screaming, hurled, too, such flaming missiles against the ships in the channel

Ropes for catapults made from womens hair
This was, of course, a genuine possibility, particularly in this area at this time. women’s hair, long and silky, plaited into heavy ropes, is ideal for the cording of catapults. It is far superior, for example, to vegetable fibers. It is also superior, in length and texture, to the hair of sleen and kaiila.
Renegades

There, to one side, on a rack, long and lovely, hung pelts of female hair. Such, as I have mentioned, particularly in time of siege, though there is always a market for it on Gor, is highly prized for the making of catapult ropes.
