This tale describes the 943 Rus expedition through the Caspian sea, for decades they had been raiding coastal Caspian cities by that point, however, no expedition was as noteworthy as this one, as the Rus sailed upstream the wide Kura river and laid waste the region, raiding land and towns, remaining in the major city of Barda for for 7 months, launching assaults from fortresses they captured on the way, until they were forced to leave.

Account of the exploits of the Rus and their issue
They are a mighty nation with vast frames and great courage.
They know not defeat, nor does any of them turn his back till he slay or be slain, it is the practice of the individual among them to carry his armor, while suspended upon his person an artisan outfit, axe, saw, hammer and the like.
He fights with spear and shield; he wears a sword and has hung upon him a lance and an instrument resembling a poniard.
They fight on foot, especially these invaders.
The Rus invade the Sallarids
When they reached the Kur they were met by Marzuban's officer who served as governor of Bardha'ah at the head of three hundred Dailemites and about the same number of Su'luks and Kurds.
He also summoned the whole people of the place to arms and was joined by some 5000 volunteers anxcious to fight these invaders.
They were however under a delusion, for not knowing the might of the Rus, whom they expected to behave like Greeks or Armenians.
When they met them in battle not more than an hour elapsed before the Rus made a fierce slaughter which routed the army of Bardha'ah; the volunteers and the rest of the troops turned their backs with the exception of the Dailemites, who stood their ground and were killed to a man, except such of them as were mounted.
The Rus then pursued the fugitives to the town, whence everyone, soldier or civilian, who had a mount to carry him, fled, leaving the town to be entered and siezed by the Rus.
Rus capture of the capital of Arran, Barda, and face off incoming Muslim armies along with the hostile local populace
I was informed by Abu'l Abbas Ibn Nudar and a number of careful enquirers how the Rus when they hurried into the town made a proclamation to the citizens;
There is no dispute between us on the matter of religion; we only desire the sovereignty; it is our duty to treat you well and yours to be loyal to us.
The armies however came against them from all sides, only to be routed again by the Rus, who made sorties.
When the Moslems charged the Rus, the people of Bardha'ah cried out Allah Akbar, and flung stones at the Rus.
The latter had charge the people of Bardha'ah to restrain themselves, and not interfere between them and the Sultan; but thought this advice was accepted by the respectable classes, the common people and the rabble would not restrain themselves, but gave vent to their feelings by attacking the Rus when the followers of the Sultan charged them.
Failed evacuation of civilians and subsequent sack of the city
After some time they issued a proclamation that none of the inhabitants were to remain in the city after three days from the day of the proclamation.
All who had mounts to carry them, their women and their children left the place.
These however, were the small minority; when the fourth day came, the majority were still there, so the Rus put them to the sword, slaughtering countless numbers.
After the massacre they bound over 10 000 men and lads with their women, their wives and their daughters; they proceeded to place the women and children in a fortress within the city called locally Shahristan, where they had taken up their quarters, lodged their troops and entrenched themselves.
They then gathered the men into the Public Mosque, set guards at the doors and bade the men ransom themselves.
Thus the Rus possessed themselves a vast amount of property. They retained for themselves the women and boys, on whom they gratified their lust, and whom they enslaved
News of Rus atrocities spread, Muslims gather a massive army for campaign against them, but they fail
When the terrible nature of the calamity was realized, and the Moslems in the different countries heard about it, they called for a general expedition.
Marzuban b. Mohammed mustered the troops and called for a general enlistment.
Volunteers joined him from all directions.
He marched at the head of 30 000 men, but in spite of the numbers that he had gathered, he was unable to make head against the Rus, or to produce any effect upon them.
Morning and evening he used to attack them, and regularly retired defeated.
The war continued to be waged in this style for many days, and the moslems were always vanquished.
Epidemic of dysentery spreads among the Rus because of excessive consumption of local fruits
It so happened that when the Rus had got into Bardha'ah, they indulged excessively in the fruit of which there are numerous sorts there. This produced an epidemic among them, as theirs is an exceedingly cold country, where no fruit tree grows, and the little fruit which they have is imported from distant regions.
When their numbers begand thereby to be reduced, Marzuban, seeking for a stratagem, bethought him of laying an ambush for them at night.
Marzuban attempts to conquer the Rus again
He therefore arranged with his army that they should make a hurried attack; when the Rus charged, he with his followers should let themselves be routed, thereby encouraging them to hope they would be able to annihilate the Moslem army; when the Rus got beyond the place where the ambush lay, Marzuban with his followers should return to the charge and shout to the ambush a cry on which they had agreed; when the Rus hadthus got between the two forces, the Moslem would have them in their power.
The morning after this scheme had been arranged, Marzuban with his followers advanced, and the Rus came out to meet them.
Their commander was mounted on an ass, and his followers came out and ranged themselves in order of battle.
Feint retreat does not go as planned, Rus retreat to city with casualties
The usual procedure occurred.
Marzuban with the Moslems took to flight and were pursued by the Rus till they had got beyond the place of the ambush. Only the Moslems continued to flee.
Marzuband afterwards narrated how, when he saw his followers act thus, and his earnest entreaties to them to renew the fight were unavailing, owning to the terror of the Rus which had seized their hearts, he recognized that if this went on, the Rus on their return would not fail to notice the ambush, which would in consequence be destroyed.
So he said, I turned round myself with my personal attendants, my brother, my staff and my retainers, having made up my mind to die a martyrs death.
Thereupon most of the Dailemites were shamed into doing the like; we charged, cried out to the ambush, which issued forth behind the Rus, fought them in brave style and killed 700 of them, including their commander.
The remainer made their way into the fortress and the town, where they had established their quarters and whither they had moved a quantity of food and stores, and where they housed their captives and their treasures.
...
(Marzupan continues his protracted campaign, but is then attacked by another Muslim ruler, the Hamdanid amir of Mosul, Nasir al-Daula, who launches a campaign of conquest, likely an act of opportunism because of the Rus invasion, which forces Marzupan to react and move westwards and successfully fend off the invasion)
...
The Rus grow weary and leave the land with their plunder
The followers of Marzuban continued to attack and besiege the Rus till the latter grew weary.
The epidemic became severe in addition.
When one of them died they buried with him his weapons, clothes and equipment, also his wife or some other of the womenfolk, and his slave, if he happened to be attached to it; this being their practice.
After their power had come to an end, the Moslems disturbed their graves and brought out a number of their swords, which are in great demand to this day for their sharpness and excellence.
When their numbers were reduced, they left by night the fortresses in which they had established their quarters, carrying on their backs all they could of their trasure, gems and fine raiment, and burning the rest.
They dragged with all women, boys and girls as they wanted, and made for the Kur, where the ships in which they had issued from their home were in readiness with their crews, and 300 Rus whom they had been supporting with portions of their booty.
They embarked and departed, and God saved the Moslems from them.
On the prowess of the Rus warriors
From persons who witnessed these Rus, I heard stories of wonder of their prowess and contempt of the Muslim forces gathereed against them. Thus there was a story current in the region which I heard from many persons, how five Rus were assembled in a garden in Bardha'ah, one of them beardless lad of fair appearence, the son of one of their chieftains, with some captive women.
When the Moslems learned of their presence, they surrounded the garden and a large number of Dailemite and others came together to fight these five Rus.
They tried hard to get a single prisoner out of the number but it was not possible, for none of them would capitulate, and they could not be killed before they had slain many times their number of the Moslems.
The beardless lad was the last survivor. When he percieved that he was going to be captured, he mounted a tree that was near him, and kept slashing away his vital parts with his sword till he fell dead.
The End
