CHAPTER VI.

MILITARY ENGINES.

To attempt to represent the knights in their manor-houses and castles

would be to enter upon an essay on the domestic and military architecture

of the Middle Ages, which would be beyond the plan of these sketches of

the mediæval chivalry. The student may find information on the subject in

Mr. Parker's "Domestic Architecture," in Grose's "Military Antiquities,"

in Viollet le Duc's "Architecture du Moyen Age," and scattered over the

publications of the various antiquarian and architectural societies. We

must, however, say a few words as to the way in which the knight defended

his castle when attacked in it, and how he attacked his neighbour's castle

or his enemy's town, in private feud or public war.

It seems to be a common impression that the most formidable aspect of

mediæval war was a charge of knights with vizor down and lance in rest;

and that these gallant cavaliers only pranced their horses round and round

the outer margin of the moat of a mediæval castle, or if they did dismount

and try to take the fortress by assault, would rage in vain against its

thick walls and barred portcullis; as in the accompanying woodcut from a

MS. romance of the early part of the 14th century (Add. 10,292, f. v.,

date A.D. 1316), where the king on his curveting charger couches his lance

against the castle wall, and has only his shield to oppose to the great

stone which is about to be hurled down upon his head. The impression is,

no doubt, due to the fact that many people have read romances, ancient and

modern, which concern themselves with the personal adventures of their

heroes, but have not read mediæval history, which tells--even more than

enough--of battles and sieges. They have only had the knight put before

them--as in the early pages of these chapters--in the pomp and pageantry

of chivalry. They have not seen him as the captain and soldier, directing

and wielding the engines of war.

Suppose the king and his chivalry in the following woodcut to be only

summoning the castle; and suppose them, on receiving a refusal to

surrender, to resolve upon an assault. They retire a few hundred yards and

dismount, and put their horses under the care of a guard. Presently they

return supported by a strong body of archers, who ply the mail-clad

defenders with such a hail of arrows that they are driven to seek shelter

behind the battlements. Seizing that moment, a party of camp followers run

forward with a couple of planks, which they throw over the moat to make a

temporary bridge. They are across in an instant, and place scaling-ladders

against the walls. The knights, following close at their heels, mount

rapidly, each man carrying his shield over his head, so that the bare

ladder is converted into a covered stair, from whose shield-roof arrows

glint and stones roll off innocuous. It is easy to see that a body of the

enemy might thus, in a few minutes, effect a lodgment on the castle-wall,

and open a way for the whole party of assailants into the interior.

[Illustration: _Summoning the Castle._]

But the assailed may succeed in throwing down the ladders; or in beating

the enemy off them by hurling down great stones ready stored against such

an emergency, or heaving the coping-stones off the battlements; or they

may succeed in preventing the assailants from effecting a lodgment on the

wall by a hand to hand encounter; and thus the assault may be foiled and

beaten off. Still our mediæval captain has other resources; he will next

order up his "gyns," _i.e._ engines of war.

The name applies chiefly to machines constructed for the purpose of

hurling heavy missiles. The ancient nations of antiquity possessed such

machines, and the knowledge of them descended to mediæval times. There

seems, however, to be this great difference between the classical and the

mediæval engines, that the former were constructed on the principle of the

bow, the latter on the principle of the sling. The classical _ballista_

was, in fact, a huge cross-bow, made in a complicated way and worked by

machinery. The mediæval _trebuchet_ was a sling wielded by a gigantic arm

of wood. In mediæval Latin the ancient name of the ballista is sometimes

found, but in the mediæval pictures the principle of the engines

illustrated is always that which we have described. We meet also in

mediæval writings with the names of the _mangona_ and _mangonella_ and the

_catapult_, but they were either different names for the same engine, or

names for different species of the same genus. The woodcut here

introduced from the MS. Add. 10,294, f. 81 V., gives a representation of a

trebuchet. A still earlier representation--viz., of the thirteenth

century--of machines of the same kind is to be found in the Arabic MS.

quoted in a treatise, "Du feu Grégois," by MM. Favé and Reinaud, and leads

to the supposition that the sling principle in these machines may have

been introduced from the East. There are other representations of a little

later date than that in the text (viz., about A.D. 1330) in the Royal MS.

16 G. VI., which are engraved in Shaw's "Dresses and Decorations." We also

possess a contemporary description of the machine in the work of Gilles

Colonne (who died A.D. 1316), written for Philip the Fair of France.[379]

"Of _perriers_," he says, "there are four kinds, and in all these machines

there is a beam which is raised and lowered by means of a counterpoise, a

sling being attached to the end of the beam to discharge the stone.

Sometimes the counterpoise is not sufficient, and then they attach ropes

to it to move the beam." This appears to be the case in our illustration.

The rope seems to be passed through a ring in the platform of the engine,

so that the force applied to the rope acts to the greater advantage in aid

of the weight of the beam. "The counterpoise may either be fixed or

movable, or both at once. In the fixed counterpoise a box is fastened to

the end of the beam, and filled with stones or sand, or any heavy body."

One would not, perhaps, expect such a machine to possess any precision of

action, but according to our author the case was far otherwise. "These

machines," he continues, "anciently called _trabutium_, cast their

missiles with the utmost exactness, because the weight acts in a uniform

manner. Their aim is so sure, that one may, so to say, hit a needle. If

the gyn carries too far, it must be drawn back or loaded with a heavier

stone; if the contrary, then it must be advanced or a smaller stone

supplied; for without attention to the weight of the stone, one cannot

hope to reach the given mark." "Others of these machines have a movable

counterpoise attached to the beam, turning upon an axis. This variety the

Romans called _biffa_. The third kind, which is called _tripantum_, has

two weights, one fixed to the beam and the other movable round it. By this

means it throws with more exactness than the _biffa_, and to a greater

distance than the trebuchet. The fourth sort, in lieu of weights fixed to

the beam, has a number of ropes, and is discharged by means of men pulling

simultaneously at the cords. This last kind does not cast such large

stones as the others, but it has the advantage that it may be more rapidly

loaded and discharged than they. In using the perriers by night it is

necessary to attach a lighted body to the projectile. By this means one

may discover the force of the machine, and regulate the weight of the

stone accordingly."[380] This, then, is the engine which our captain,

repulsed in his attempt to take the place by a _coup de main_, has ordered

up, adjusting it, no doubt, like a good captain, with his own eye and

hand, until he has got it, "so to say, to hit a needle," on the weak

points of the place. It was usual in great sieges to have several of them,

so that a whole battery might be set to work to overmaster the defence.

[Illustration: _The Assault._]

We must bear in mind that similar engines were, it is probable, usually

mounted on the towers of the castle. We should judge from the roundness of

the stones which the defenders in both the preceding woodcuts are throwing

down by hand upon the enemy immediately beneath, that they are the stones

provided for the military engines. We find that, as in modern times cannon

is set to silence the cannon of the enemy, so that a battle becomes, for a

time at least, an artillery duel, so engine was set to silence engine. In

the account which Guillaume des Ormes gives of his defence of the French

town of Carcasonne in 1240 A.D., he says: "They set up a mangonel before

our barbican, when we lost no time in opposing to it from within an

excellent Turkish petrary, which played upon the mangonel and those about

it, so that when they essayed to cast upon us, and saw the beam of our

petrary in motion, they fled, utterly abandoning their mangonel."

There was also an engine called an _arbalast_, or _spurgardon_, or

_espringale_, which was a huge cross-bow mounted on wheels, so as to be

movable like a field-piece; it threw great pointed bolts with such force

as to pass successively through several men.

If the engines of the besiegers were silenced, or failed to produce any

decisive impression on the place, the captain of the assailants might try

the effect of the ram. We seldom, indeed, hear of its use in the Middle

Ages, but one instance, at least, is recorded by Richard of Devizes, who

says that Richard I., at the siege of Messina, forced in the gates of the

city by the application of the battering-ram, and so won his way into the

place, and captured it. The walls of mediæval fortifications were so

immensely thick, that a ram would be little likely to break them. The

gates, too, of a castle or fortified gate-tower were very strong. If the

reader will look at the picture of a siege of a castle, given on page 373,

he will see a representation of a castle-gate, which will help him to

understand its defences. First he will see that the drawbridge is raised,

so that the assailant has to bridge the moat before he can bring his

battering-ram to bear. Suppose the yawning gulf bridged with planks or

filled in with fascines, and the ram brought into position, under fire

from the loops of the projecting towers of the gate as well as from the

neighbouring battlements, then the bridge itself forms an outer door which

must first be battered down. Behind it will be found the real outer-door,

made as strong as oak timber and iron bolts can make it. That down, there

is next the grated portcullis seen in two previous woodcuts, against which

the ram would rattle with a great clang of iron; but the grating, with its

wide spaces, and having plenty of "play" in its stone groove, would baffle

the blows by the absence of a solid resistance, and withstand them by the

tenacity of wrought-iron. Even if the bars were bent and torn till they

afforded a passage, the assailants would find themselves in the narrow

space within the gate-tower confronted by another door, and exposed to

missiles poured upon them from above. It is, perhaps, no wonder that we

hear little of the use of the ram in mediæval times; though it might be

useful occasionally to drive in some ill-defended postern.

The use of the regular mine for effecting a breach in the wall of a

fortified place was well known, and often brought to bear. The miners

began their work at some distance, and drove a shaft underground towards

the part of the fortifications which seemed most assailable; they

excavated beneath the foundations of the wall, supporting the substructure

with wooden props until they had finished their work. Then they set fire

to the props, and retired to see the unsupported weight of the wall

bringing it down in a heap of ruins. The operation of mining was usually

effected under the protection of a temporary pent-house, called a _cat_ or

_sow_. William of Malmesbury describes the machine as used in the siege of

Jerusalem, at the end of the eleventh century. "It is constructed," he

says, "of slight timbers, the roof covered with boards and wicker-work,

and the sides protected with undressed hides, to protect those who are

within, who proceed to undermine the foundations of the walls." Our next

woodcut gives a very clear illustration of one of these machines, which

has been moved on its wheels up to the outer wall of a castle, and beneath

its protection a party of men-at-arms are energetically plying their

miner's tools, to pick away the foundation, and so allow a portion of the

wall to settle down and leave an entrance. The methods in which this mode

of attack was met were various. We all remember the Border heroine, who,

when her castle was thus attacked, declared she would make the sow farrow,

viz., by casting down a huge fragment of stone upon it. That this was one

way of defence is shown in the woodcut, where one of the defenders, with

energetic action, is casting down a huge stone upon the sow. That the roof

was made strong enough to resist such a natural means of offence is shown

by the stones which are represented as lodged all along it. Another more

subtle counteraction, shown in the woodcut, was to pour boiling water or

boiling oil upon it, that it might fall through the interstices of the

roof, and make the interior untenable. No doubt means were taken to make

the roof liquid-tight, for the illustration represents another mode of

counteraction (of which we have met with no other suggestion), by driving

sharp-pointed piles into the roof, so as to make holes and cracks through

which the boiling liquid might find an entrance. If these means of

counteracting the work of the cat seemed likely to be unavailing, it still

remained to throw up an inner line of wall, which, when the breach was

made, should extend from one side to the other of the unbroken wall, and

so complete the circumvallation. This, we have evidence, was sometimes

done with timber and planks, and a sort of scaffolding was erected on the

inner side, which maintained the communication along the top of the walls,

and enabled the soldiers to man the top of this wooden wall and offer a

new resistance to the besiegers as they poured into the breach. The mine

was also, in ancient as in modern times, met by a counter-mine.

[Illustration: _The Cat._ (Royal, 16 G VI.)]

Another usual machine for facilitating the siege of fortified places was a

movable tower. Such an engine was commonly prepared beforehand, and taken

to pieces and transported with the army as a normal part of the

siege-train. When arrived at the scene of operations, it was put together

at a distance, and then pushed forward on wheels, until it confronted the

walls of the place against which it was to operate. It was intended to put

the besiegers on a level and equality with the besieged. From the roof the

assailants could command the battlements and the interior of the place,

and by their archers could annoy the defence. A movable part of the front

of the tower suddenly let fall upon the opposite battlements, at once

opened a door and formed a bridge, by which the besiegers could make a

rush upon the walls and effect a lodgment if successful, or retreat if

unsuccessful to their own party.

Such a tower was constructed by Richard I. in Cyprus, as part of his

preparation for his Crusade. An illustration of a tower thus opposed to a

castle--not a very good illustration--is to be found in the Royal MS., 16

G. VI., at folio 278 v. Another, a great square tower, just level with the

opposing battlements, with a kind of sloping roof to ward off missiles, is

shown in the MS. _Chroniques d'Angleterres_ (Royal 16, E. IV.), which was

illuminated for Edward IV. Again, at f. 201 of the same MS., is another

representation of wooden towers opposed to a city.

If the besieged could form a probable conjecture as to the point of the

walls towards which the movable tower, whose threatening height they saw

gradually growing at a bow-shot from their walls, would be ultimately

directed, they sometimes sent out under cover of night and dug pitfalls,

into which, as its huge bulk was rolled creaking forward, its fore wheels

might suddenly sink, and so the machine fall forward, and remain fixed and

useless. As it approached, they also tried to set it on fire by missiles

tipped with combustibles. If it fairly attained its position, they

assailed every loop and crevice in it with arrows and crossbow bolts, and

planted a strong body of men-at-arms on the walls opposite to it, and in

the neighbouring towers, to repel the "boarders" in personal combat. A

bold and enterprising captain did not always wait for the approach of

these engines of assault, but would counter-work them as he best could

from the shelter of his walls. He would sometimes lower the drawbridge,

and make a sudden sally upon the unfinished tower or the advancing sow,

beat off the handful of men who were engaged about it, pile up the

fragments and chips lying about, pour a few pots of oil or tar over the

mass, and set fire to it, and return in triumph to watch from his

battlements how his fiery ally would, in half an hour, destroy his enemy's

work of half a month. In the early fourteenth century MS. Add. 10,294, at

fol. 740, we have a small picture of a fight before a castle or town, in

which we see a column of men-at-arms crossing the drawbridge on such an

expedition. And again, in the plates in which Hans Burgmaier immortalised

the events of the reign of the Emperor Maximilian, a very artistic

representation of a body of men-at-arms, with their long lances, crowding

through the picturesque gate and over the drawbridge, brings such an

incident vividly before us.

The besiegers on their part did not neglect to avail themselves of such

shelter as they could find or make from the shot and from the sallies of

the enemy, so as to equalise as much as practicable the conditions of the

contest. The archers of the castle found shelter behind the merlons of the

battlements, and had the windows from which they shot screened by movable

shutters; as may be seen in the next woodcut of the assault on a castle.

It would have put the archers of the assailants at a great disadvantage if

they had had to stand out in the open space, exposed defenceless to the

aim of the foe; all neighbouring trees which could give shelter were, of

course, cut down, in order to reduce them to this defenceless condition,

and works were erected so as to command every possible coigne of vantage

which the nooks and angles of the walls might have afforded. But the

archers of the besiegers sought to put themselves on more equal terms with

their opponents by using the _pavis_ or _mantelet_. The pavis was a tall

shield, curved so as partly to envelop the person of the bearer, broad at

the top and tapering to the feet. We sometimes see cross-bowmen carrying

it slung at their backs (as in Harl. 4,379, and Julius E. IV., f. 219,

engraved on p. 294), so that after discharging a shot they could turn

round and be sheltered by the great shield while they wound up their

instrument for another shot. Sometimes this shield seems to have been

simply three planks of wood nailed together, which stood upright on the

ground, and protected the soldier effectively on three sides. There are

illustrations of it in the MS. Royal 20 C vii. (temp. Rich. II.), at f.

19, f. 24 v., and f. 29 v., and in the MS. Harl. 4,382, f. 133 v. and f.

154 v. The mantelet was a shield still more ample, and capable of being

fixed upright by a prop, so that it formed a kind of little movable fort

which the bowman, or man-at-arms, could carry out and plant before the

walls, and thence discharge his missiles, or pursue any other operation,

in comparative safety from the smaller artillery of the enemy. The most

interesting example which we have met of the employment of the pavis and

mantelet, is in a picture in the Harl. MS. 4,425, at f. 133. The woodcut

on the previous page represents only a portion of the picture, the whole

of which is well worth study. The reader will see at once that we have

here the work of a draughtsman of far superior skill to that of the

limners of the rude illuminations which we have previously given. The

background really gives us some adequate idea of the appearance of an

Edwardian castle with its barbican and drawbridge, its great tower with

the heads of the defenders just peeping over the battlements. We must call

attention to the right-hand figure in the foreground, who is clad in a

_pourpoint_, one of the quilted armours which we have formerly described,

because it is the best illustration of this species of armour we have met

with. But the special point for which we give the woodcut here, is to

illustrate the use of the mantelet. It will be seen--though somewhat

imperfectly, from the fragment of the engraving introduced--that these

defences have been brought up to the front of the attacking party in such

numbers as to form an almost continuous wall, behind which the men-at-arms

are sheltered; on the right are great fixed mantelets, with a hole in the

middle of each, through which the muzzle of a gun is thrust; while the

cannoniers work their guns as behind the walls of a fort.

[Illustration: _Use of the Pavis, etc._]

[Illustration: _Cannon and Mortar._]

Similar movable defences, variously constructed, continued to be used down

to a very late period. For example, in some large plans of the array of

the army of Henry VIII., preserved in the British Museum (Cottonian MS.,

Augustus III., f. 1 v.), the cannon are flanked by huge mantelets of

timber, which protect the cannoniers. In the one engraved between pp. 454

and 455, we see a representation of the commencement of the battle,

showing some of the mantelets overthrown by the assault of soldiers armed

with poleaxes. In modern warfare the sharpshooter runs out into the open,

carrying a sand-bag by way of pavis, behind which he lies and picks off

the enemy, and the artillery throw up a little breastwork, or mantelet, of

sand-bags.

Sometimes the besieging army protected itself by works of a still more

permanent kind. It threw up embankments with a pallisade at top, or

sometimes constructed a breastwork, or erected a fort, of timber. For

example, in the Royal MS. 14 E. IV., at f. 14, we have a picture of an

assault upon a fortified place, in which the besiegers have strengthened

their position by a timber breastwork. It is engraved at p. 443; the whole

picture is well worth study. Again, in the Cottonian MS., Augustus V., at

folio 266, is a camp with a wooden fence round it.

An army in the field often protected its position in a similar way. So far

back as the eleventh century the historians tell us that William the

Conqueror brought over a timber fort with him to aid his operations. The

plan of surrounding the camp with the waggons and baggage of the army is

perhaps one of the most primitive devices of warfare, and we find it used

down to the end of the period which is under our consideration. In the MS.

already mentioned, Augustus III., on the reverse of folio 4, is a picture

of an army of the time of Henry VIII. encamped by a river, and enclosed on

the open sides by the baggage, and by flat-bottomed boats on their

carriages, which we suppose have been provided for the passage of the

stream.

The siege of Bedford Castle, as described by Roger Wendover, in the year

1224, gives a good historical instance of the employment of these various

modes of attacking a stronghold at that period. The castle was being held

against the king, who invested it in person. Two towers of wood were

raised against the walls, and filled with archers; seven mangonels cast

ponderous stones from morning to night; sappers approached the walls under

the cover of the cat. First the barbican, then the outer bailey was taken.

A breach in the second wall soon after gave the besiegers admission to the

inner bailey. The donjon still held out, and the royalists proceeded to

approach it by means of their sappers. A sufficient portion of the

foundations having been removed, the stancheons were set on fire, one of

the angles sank deep into the ground, and a wide rent laid open the

interior of the keep. The garrison now planted the royal standard on the

walls, and sent the women to implore mercy. But a severe example was made

of the defenders, in order to strike terror among the disaffected in other

parts of the realm.[381]

[Illustration: _Cannon._]

Among the occasional warlike contrivances, stinkpots were employed to

repel the enemy, and the Greek fire was also occasionally used. A

representation of the use of stinkpots, and also of the mode of using the

Greek fire, may be seen in the Royal MS. 18 E. V., at f. 207 (date 1473

A.D.).

Those more terrible engines of war which ultimately revolutionised the

whole art of warfare, which made the knight's armour useless, and the

trebuchet and arbalest the huge toys of an unscientific age, were already

introduced; though they were yet themselves so immature, that for a time

military men disputed whether the old long bow or the new fire-arm was the

better weapon, and the trebuchet still held its place beside the cannon.

In the old illuminations we find mediæval armour and fire-arms together in

incongruous conjunction. The subject of the use of gunpowder is one of so

much interest, that it deserves to be treated in a separate chapter.
