In what manner Alexander made his bridge over the Indus neither

Aristoboulos nor Ptolemy, the authorities whom I chiefly follow, have

given any account; nor can I decide for certain whether the passage was

bridged with boats, as was the Hellespont by Xerxes and as were the

Bosporos and the Istros by Darius,[91] or whether the bridge he made over

the river was one continuous piece of work. I incline, however, to think

that the bridge must have been made of boats,[92] for neither would the

depth of the river have admitted the construction of an ordinary kind of

bridge, nor could a work so vast and difficult have been executed in so

short a time. But if the passage was bridged with boats I cannot decide

whether the vessels being fastened together with cables and anchored in

a row sufficed to form a bridge as did those by which, as Herodotos the

Halikarnassian says, the Hellespont was joined, or whether the method was

that which is used by the Romans in bridging the Istros and the Keltic

Rhine,[93] and by which they bridged the Euphrates and the Tigris as

often as necessity required. Since, however, the Romans, as far as my

knowledge goes, have found that the bridging of rivers by boats is the

most expeditious method of crossing them, I think it worth a description

here. The vessels at a preconcerted signal are let go from their moorings

and rowed down stream not prow but stern foremost. The current of course

carries them downward, but a small pinnace furnished with oars holds

them back till they settle into their appointed place. Then baskets of

wicker work, pyramid-shaped and filled with rough stones, are lowered

into the river from the prow of each vessel to make it hold fast against

the force of the current. As soon as one of those vessels has been held

fast another is in the same way anchored with its prow against the stream

as far from the first as is commensurate with their bearing the strain

of what is put upon them. On both of them beams of wood are rapidly laid

lengthwise, and on these again planks are placed crosswise to bind them

together. In this manner the work proceeds through all the vessels which

are required for bridging the passage. At each end of the structure

firmly fixed railed gangways are thrown forward to the shore so that

horses and beasts of burden may with the greater safety enter upon it.

These gangways serve at the same time to bind the bridge to the shore. In

a short time the whole is completed amid great noise and bustle, though

discipline is by no means lost sight of as the work proceeds. In each

vessel the occasional exhortations of the overseers and their rebukes

of negligence neither prevent orders from being heard nor the work from

being quickly executed.

_Chapter VIII.—Alexander arrives at Taxila—Receives an embassy from

Abisares and advances to the Hydaspês_

This method has been practised by the Romans from of old, but how

Alexander bridged the river Indus I cannot say, for even those who served

in his army are silent on the matter. But the bridge was made, I should

think, as nearly as possible in the way described, or if it was otherwise

contrived let it be so.

When Alexander had crossed to the other side of the Indus he again

offered sacrifice according to his custom. Then marching away from

the Indus he arrived at Taxila,[94] a great and flourishing city, the

greatest indeed of all the cities which lay between the river Indus and

the Hydaspês. Taxilês, the governor of the city, and the Indians who

belonged to it received him in a friendly manner, and he therefore added

as much of the adjacent country to their territory as they requested.

While he was there Abisarês, the king of the Indians of the hill-country,

sent him an embassy which included his own brother and other grandees

of his court. Envoys came also from Doxarês, the chief of the province,

and those like the others brought presents. Here again in Taxila

Alexander offered his customary sacrifices and celebrated a gymnastic

and equestrian contest. Having appointed Philip, the son of Makhatas,

satrap of the Indians of that district, he left a garrison in Taxila and

those soldiers who were invalided, and then moved on towards the river

Hydaspês—for he had learned that Pôros with the whole of his army lay on

the other side of that river resolved either to prevent him from making

the passage or to attack him when crossing.[95] Upon learning this

Alexander sent back Koinos, the son of Polemokratês, to the river Indus

with orders to cut in pieces all the boats that had been constructed for

the passage of the Indus and to bring them to the river Hydaspês. In

accordance with these orders the smaller boats were cut each into two

sections and the thirty-oared galleys into three, and the sections were

then transported on waggons to the banks of the Hydaspês. There the boats

were reconstructed, and appeared as a flotilla upon that river. Alexander

then taking the forces which he had with him when he arrived at Taxila

and 5000 of the Indians commanded by Taxilês and the chiefs of that

country advanced towards the Hydaspês.[96]

_Chapter IX.—Alexander on reaching the Hydaspês finds Pôros prepared to

dispute its passage_

Alexander encamped on the banks of the river,[97] and Pôros was seen on

the opposite side, with all his army and his array of elephants around

him.[98] Against the place where he saw Alexander had encamped, he

remained himself to guard the passage, but he sent detachments of his

men, each commanded by a captain, to guard all parts of the river where

it could be easily forded, as he was resolved to prevent the Macedonians

from effecting a landing. When Alexander saw this, he thought it

expedient to move his army from place to place, so that Pôros might be at

a loss to discover his real intentions. For this purpose he divided his

army into many parts, and some of the troops he led himself in different

directions, sometimes to ravage the enemy’s country, and sometimes to

find out where he could most easily ford the river. He placed various

commanders at various times over different divisions of his army, and

despatched them also in different directions. At the same time he caused

provisions to be conveyed to the camp from all parts of the country on

this side of the river, to impress Pôros with the conviction that he

intended to remain where he was near the bank, till the waters of the

river subsided in winter, and afforded him a large choice of passages.

As the boats were constantly plying up and down the stream, and the

skins were being filled with hay, while all the bank was lined, here with

horse and there with foot, all this prevented Pôros from resting and

concentrating his preparations at any one point selected in preference

to any other as the best for defending the passage. At this time of the

year besides, all the Indian rivers were swollen and flowing with turbid

and rapid currents, for the sun is then wont to turn towards the summer

tropic.[99] At this season incessant rains deluge the soil of India, and

the snows of the Kaukasos then melting flood the numerous rivers to which

they give birth. In winter they again subside and become small and clear,

and in many places fordable, with the exception of the Indus and the

Ganges, and perhaps some one or two others. The Hydaspês at all events

does become fordable.

_Chapter X.—Alexander’s devices to deceive Pôros and steal the passage of

the river_

Alexander therefore publicly announced that he would remain where he was

throughout that season of the year if his passage was for the present

to be obstructed, but he continued as before waiting in ambush to see

whether he could anywhere rapidly steal a passage to the other side

without being observed. He clearly saw that it was impossible for him to

cross where Pôros himself had encamped near the bank of the Hydaspês, not

only because he had so many elephants, but also because his large army

arrayed for battle, and splendidly accoutred, was ready to attack his

troops the moment they landed. He foresaw besides that his horses would

refuse to mount the opposite bank, where the elephants would at once

encounter them, and by their very aspect and their roaring would terrify

them outright; nor did he think that even before they gained the shore

they would remain upon the inflated hides during the passage; but that on

seeing the elephants even at a distance off, they would become frantic

and leap into the water. He resolved therefore to steal the passage, and

to do this in the following way. Leading out by night the greater part

of his cavalry along the river bank in different directions, he ordered

them to set up a loud clamour, raise the war-shout,[100] and fill the

shores with every kind of noise, as if they were really preparing to

attempt the passage. Pôros marched meanwhile along the opposite bank, in

the direction of the noise, having his elephants with him, and Alexander

gradually accustomed him to lead out his men in this way in opposition.

When this had been done repeatedly, and the men did nothing more than

make a great noise and shout the war-cry, Pôros no longer made any

counter-movement when the cavalry issued out from the camp, but remained

within his own lines, his spies being, however, posted at numerous points

along the bank. When Alexander had thus quieted the suspicions of Pôros

about his nocturnal attempts, he devised the following stratagem.

_Chapter XI.—Arrangements made by Alexander for crossing the Hydaspês

unobserved_

There was a bluff ascending from the bank of the Hydaspês at a point

where the river made a remarkable bend, and this was densely covered

with all sorts of trees. Over against it lay an island in the river

overspread with jungle, an untrodden and solitary place. Perceiving that

this island directly faced the bluff, and that both places were wooded

and adapted to screen his attempt to cross the river, he decided to take

his army over this way. Now the bluff and the island were 150 stadia

distant from the great camp.[101] But along the whole of the bank he

had posted running sentries[102] at a proper distance for keeping each

other in sight, and readily transmitting along the line any orders that

might be received from any quarter. In every direction, moreover, shouts

were raised by night, and fires were burnt for many nights together. But

when he had made up his mind to attempt the passage, the preparations

for crossing were made in the camp without any concealment. In the camp

Krateros had been left with his own division of the cavalry, and the

Arakhosian and Parapamisadan horsemen, together with the brigades of

the Macedonian phalanx commanded by Alketas and Polysperchon and the

contingent of 5000 men under the chiefs of the hither Indians. He had

ordered Krateros not to attempt to cross the river before Pôros moved off

against them, or before learning that he was flying from the field, and

that they were victorious. “If, however,” said he, “Pôros with one part

of his army advances against me while he leaves the other part and his

elephants in his camp, then please to remain where you are; but if Pôros

takes all his elephants with him, and a portion of the rest of his army

is left behind in the camp, then do you cross the river with all possible

speed; for,” added he, “it is the elephants only which make it impossible

for the horses to land on the other bank. The rest of the army can cross

over without difficulty.”

_Chapter XII.—Alexander crosses the Hydaspês_

Such were the instructions given to Krateros; but half-way between the

island and the main camp in which he had been left, there were posted

Meleager, Attalos and Gorgias, with the mercenary cavalry and infantry,

who had received orders to cross to the other side in detachments, into

which their ranks were to be separated as soon as they saw the Indians

fairly engaged in battle. He then selected to be taken under his own

command the corps of body-guards called Companions, the regiments of

cavalry under Hêphaistiôn, Perdikkas and Dêmêtrios, also the Baktrian,

Sogdian, and Skythian cavalry, and the Daan horse-archers, and from the

phalanx of infantry the hypaspists, the brigade of Kleitos and Koinos,

and the archers and the Agrianians, and with these troops he marched with

secrecy, keeping at a considerable distance from the bank that he might

not be seen to be moving towards the island and the bluff, from which he

intended to cross over to the other side. There in the night the skins,

which had long before been provided for the purpose, were stuffed with

hay, and securely stitched up. During the night a violent storm of rain

came on, whereby his preparations and the attempt at crossing were not

betrayed to the enemy by the rattle of arms and the shouting of orders,

since the thunder and rain drowned all other sounds. Most of the boats

which he had ordered to be cut into sections had been conveyed to this

place, and when secretly pieced together again were hidden away in the

woods along with the thirty-oared galleys. Towards daybreak the wind had

died down and the rain ceased. The rest of the army then crossed over

in the direction of the island, the cavalry mounted on the skin pontoon

rafts, and as many of the foot-soldiers as the boats could hold embarked

in them. They so proceeded, that they were not seen by the sentries

posted by Pôros till they had passed beyond the island, and were not far

from the bank.

_Chapter XIII.—Incidents of the passage of the river_

Alexander himself embarked on a thirty-oared galley, and went over

accompanied by Ptolemy, Perdikkas, and Lysimachos, his body-guards, and

by Seleukos, one of the companions, who was afterwards king, and by

one half of the hypaspists, the other half being on board of the other

galleys of like size. As soon as the soldiers had passed beyond the

island, they steered for the bank, being now full in view of the enemy,

whose sentinels on seeing their approach galloped off at the utmost speed

of each man’s horse to carry the tidings to Pôros. Meanwhile Alexander

was himself the first to disembark, and taking the horsemen who had been

conveyed over in his own and the other thirty-oared galleys, he at once

formed them into line as they kept landing, for the cavalry had orders

to be the first to disembark. At the head of these duly marshalled he

moved forward. Owing, however, to his ignorance of the locality he had

unawares landed not on the mainland, but upon an island, the great size

of which prevented it all the more from being recognised as an island.

It was separated from the mainland by a branch of the river in which the

water was shallow; but the violent storm of rain which had lasted the

most of the night had so swollen the stream that the horsemen could not

find the ford, and he feared that the latter part of the passage would

be as laborious as the first. When at last the ford was found he led

his men through it with difficulty; for the water where deepest reached

higher than the breasts of the foot soldiers, and as for the horses their

heads only were above the river. When he had crossed this piece of water

also, he selected the mounted corps of body-guards, and the best men from

the other squadrons of cavalry, and brought them from column into line

upon the right wing.[103] Then in front of all the cavalry he posted the

horse archers, and next in line to the cavalry and in front of all the

infantry the royal hypaspists commanded by Seleukos. Next to these again

he placed the royal foot guards, and then the other hypaspists, each in

what happened to be the order of his precedence for the time being. At

each extremity of the phalanx were posted the archers and the Agrianians

and the javelin men.

_Chapter XIV.—Skirmish with the son of Pôros at the landing-place_

Alexander having made these dispositions, ordered the infantry, which

numbered nearly 6000 men, to follow him at the ordinary marching pace and

in regular order, for when he saw that he was superior in cavalry, he

took with himself only the horsemen, about 5000 in number, and led them

forward at a rapid pace. Taurôn, the captain of the archers, he ordered

to hasten forward with his men to give support to the cavalry. He had

come to the conclusion that if Pôros engaged him with all his troops he

would either, without difficulty, overpower him by charging with his

cavalry, or would remain on the defensive till the infantry came up

during the action, or that if the Indians, terrified by the marvellous

audacity of his passage of the river, should take to flight, he would be

able to pursue them closely, and the slaughter being thus all the greater

there would not be left much more work for him to do.

Aristoboulos says that the son of Pôros arrived with about 60 chariots

before Alexander made the final passage from the large island, and that

he could have hindered Alexander from landing (for he made the passage

with difficulty even when no one opposed him), if the Indians had but

leaped down from their chariots and fallen upon those who first stepped

on shore. The prince, however, passed by with his chariots, and allowed

Alexander to accomplish the passage in complete safety. Against these

Indians Alexander, he says, despatched his horse archers, who easily

put them to a rout which was by no means bloodless. Other writers say

that while the troops were landing an encounter took place between the

Indians who had come with the son of Pôros and Alexander at the head

of his cavalry, and that as the son of Pôros had come with a superior

force Alexander himself was wounded by the Indian prince, and that his

favourite horse Boukephalas was killed, having been wounded, like his

master, by the son of Pôros. But Ptolemy, the son of Lagos, with whom I

agree, gives a different account, for he states, like the others, that

Pôros sent off his son, but not in command of merely 60 chariots; and

indeed it is not at all likely that Pôros, on learning from the scouts

that either Alexander himself, or, at all events, a part of his army,

had made the passage of the Hydaspês, would have sent his own son with

no more than 60 chariots, which, considered as a reconnoitring party,

would have been too numerous, and not rapid in retreat, but considered as

meant to repel such of the enemy as had not yet crossed the river, and

to attack those who had already landed, an altogether inadequate force.

He says that the son of Pôros arrived at the head of 2000 men and 120

chariots, and that Alexander had made even the final passage from the

island before the prince appeared upon the scene.

_Chapter XV.—The arrangements made by Pôros for the conflict_

Ptolemy states further that Alexander at first despatched against the

prince the horse archers, and led the cavalry himself, under the belief

that Pôros was advancing against him with the whole of his army, and

that this was a body of advanced cavalry thrown forward by Pôros. But

when he discovered what the real strength of the Indians was he then

briskly charged them with what cavalry he had with him. When they noticed

that Alexander himself and his body of cavalry did not charge them in

an extended line, but by squadrons, their ranks gave way, and 400 of

their horsemen fell, and among them the son of Pôros. Their chariots,

moreover, were captured, horses and all, for they proved heavy in the

retreat and useless in the action itself, by having stuck fast in the

clay. When the horsemen who had escaped from this rout reported one after

another to Pôros that Alexander himself had crossed the river with the

strongest division of his army, and that his son had been slain in the

fight, he was still at a loss what to determine, for the division which

had been left with Krateros in the great camp right opposite to his own

position appeared to be undertaking the passage, but he at last decided

to march with all his forces against Alexander and fight it out with

the strongest division of the Macedonians led by the king in person. He

nevertheless left there in his camp a few of the elephants and a small

force to deter the cavalry under the command of Krateros from landing. He

then took all his cavalry, 4000 strong, all his chariots, 300 in number,

200 of his elephants, and 30,000 efficient infantry, and marched against

Alexander. When he found a place where he saw there was no clay, but

that the ground from its sandy nature was all flat and firm, and suited

for the movements of cavalry whether charging or falling back, he then

drew up his army in order of battle,[104] posting his elephants in the

front line at intervals of at least 100 feet, so as to have his elephants

ranged in front before the whole body of his infantry, and so to spread

terror at all points among Alexander’s cavalry. He took it for certain

besides that none of the enemy would have the audacity to push in at

the intervals between the elephants—not the cavalry, since their horses

would be terrified by these animals, and much less the infantry, since

they would be checked in front by his heavy-armed foot soldiers falling

upon them, and trampled down when the elephants wheeled round upon them.

Behind these he drew up his infantry, which did not close up in one line

with the elephants, but formed a second line in their rear, so that the

regiments were only partly pushed forward into the intervals. He had also

troops of infantry posted on the wings beyond the elephants, and on both

sides of the infantry the cavalry had been drawn up, and in front of it

the chariots.

_Chapter XVI.—The plan of attack adopted by Alexander_

In this manner had Pôros arranged his troops. As soon as Alexander

perceived that the Indians had been drawn up in battle order he made his

cavalry halt, that he might get in hand each regiment of the infantry

as it came up; and even when the phalanx by a rapid march had effected

a junction with the cavalry he still did not at once marshal its ranks

and lead it into action, and thus expose the men, while tired and out

of breath, to the barbarians, who were quite fresh, but he gave them

time, while he rode round their ranks, to rest until they could recover

themselves. When he had observed how the Indians were arranged he

made up his mind not to advance against the centre, in front of which

the elephants had been posted, while the intervals between them had

been filled with compact masses of infantry, for he feared lest Pôros

should reap the advantage which he had calculated on deriving from that

arrangement. But as he was superior in cavalry he took the greater part

of that force, and marched along towards the left wing of the enemy to

make his attack in this quarter.[105] Koinos he sent at the head of his

own regiment of horse and that of Dêmêtrios to the right, and ordered

him, when the barbarians on seeing what a dense mass of cavalry was

opposed to them, should be riding along to encounter it, to hang close

upon their rear.[106] The command of the phalanx of infantry he committed

to Seleukos, Antigenês, and Taurôn, who received orders not to take part

in the action till they saw that the phalanx of infantry and the cavalry

of the enemy were thrown into disorder by the cavalry under his own

command.

When the Indians were now within reach of his missiles he despatched

against their left wing the horse archers, who were 1000 strong, to throw

the enemy in that part of the field into confusion with storms of arrows

and charges of their horses. He marched rapidly forward himself with the

companion cavalry against the left wing of the barbarians, making haste

to attack their cavalry in a state of disorder while they were still in

column, and before they could deploy into line.
