When spring came, and the snow and ice were loosed, then Thorolf launched a large warship of his own, and he had it made ready, and equipped his house-carles, taking with him more than a hundred men; and a goodly company there were, and well weaponed. And when a fair wind blew, Thorolf steered southwards along the coast till he came to Byrda; then they held an outer course outside the islands, but at times through channels between hill-slopes. Thus they coasted on southwards, and had no tidings of men till they came eastwards to Vik. There they heard that king Harold was in Vik, meaning in the summer to go into Upland. The people of the country knew nothing of Thorolf's voyage. With a fair wind he held on south to Denmark, and thence into the Baltic, where he harried through that summer, but got no good booty. In the autumn he steered back from the east to Denmark, at the time when the fleet at Eyrar was breaking up. In the summer there had been, as was usual, many ships from Norway. Thorolf let all these vessels sail past, and did not show himself. One day at eventide he sailed into Mostrarsound , where in the haven was a large ship of burden that had come from Eyrar. The steersman was named Thorir Thruma; he was a steward of king Harold's, manager of his farm at Thruma, a large farm in which the king used to make a long stay when he was in Vik. Much provision was needed for this farm, and Thorir had gone to Eyrar for this, to buy a cargo, malt, wheat, and honey; and much wealth of the king's had he for that end. Thorolf made for this ship, and offered Thorir and his crew the choice to defend themselves, but, as they had no force to make defence against such numbers, they yielded. The ship with all its freight Thorolf took, but Thorir he put out on an island.

Then he sailed northwards along the coast with both the ships; but when they came to the mouth of the Elbe, they lay there and waited for night. And when it was dark, they rowed their long-ship up the river and stood in for the farm-buildings belonging to Hallvard and Sigtrygg. They came there before daybreak, and formed a ring of men round the place, then raised a war-whoop and wakened those within, who quickly leapt up to their weapons. Thorgeir at once fled from his bedchamber. Round the farmhouse were high wooden palings: at these Thorgeir leapt, grasping with his hand the stakes, and so swung himself out of the yard. Thorgils Yeller was standing near; he made a sweep with his sword at Thorgeir, and cut off his hand along with the fence-stake. Then Thorgeir escaped to the wood, but Thord, his brother, fell slain there, and more than twenty men. Thorolf's band plundered and burnt the house, then went back down the river to the sea.

With a fair wind they sailed north to Vik; there again they fell in with a large merchant-ship belonging to men of Vik, laden with malt and meal. For this ship they made; but those on board, deeming they had no means of defence, yielded, and were disarmed and put on shore, and Thorolf's men, taking the ship and its cargo, went on their way.

Thorolf had now three ships, with which he sailed westwards by Fold. Then they took the high road of the sea to Lidandisness, going with all despatch, but making raid and lifting cattle on ness and shore. Northwards from Lidandisness they held a course further out, but pillaged wherever they touched land. But when Thorolf came over against the Firths, then he turned his course inward, and went to see his father Kveldulf, and there they were made welcome. Thorolf told his father what had happened in his summer voyage; he stayed there but a short time, and Kveldulf and his son Grim accompanied him to the ship.

But before they parted Thorolf and his father talked together, and Kveldulf said: 'I was not far wrong, Thorolf, in telling thee, when thou wentest to join king Harold's guard, that neither thou nor we thy kindred would in the long run get good-fortune therefrom. Now thou hast taken up the very counsel against which I warned thee; thou matchest thy force against king Harold's. But though thou art well endowed with valour and all prowess, thou hast not luck enough for this, to play on even terms with the king - a thing wherein no one here in the land has succeeded, though others have had great power and large force of men. And my foreboding is that this is our last meeting: it were in the course of nature from our ages that thou shouldst overlive me, but I think it will be otherwise.'

After this Thorolf embarked and went his way. And no tidings are told of his voyage till he arrived home at Sandness, and caused to be conveyed to his farm all the booty he had taken, and had his ship set up upon land. There was now no lack of provision to keep his people through the winter. Thorolf stayed on at home with no fewer men than in the winter before.

Þá er vár kom ok snæ leysti ok ísa, þá lét Þórólfr fram setja langskip mikit, er hann átti, ok lét þat búa ok skipaði húskörlum sínum ok hafði með sér meir en hundrað manna. Var þat lið it fríðasta ok vápnat allvel.

En er byr gaf, helt Þórólfr skipinu suðr með landi, ok þegar er hann kom suðr um Byrðu, þá heldu þeir útleið fyrir útan eyjar allar, en stundum svá, at sjór var í miðjum hlíðum, létu svá ganga suðr fyrir landit, höfðu ekki tíðendi af mönnum, fyrr en þeir kómu austr í Vík. Þá spurðu þeir, at Haraldr konungr var í Víkinni ok hann ætlaði um sumarit at fara til Upplanda. Ekki vissu landsmenn til um ferð Þórólfs. Honum byrjaði vel, ok helt hann suðr til Danmerkr ok þaðan í Austrveg ok herjaði þar um sumarit ok varð ekki gott til fjár.

Um haustit helt hann austan til Danmerkr í þann tíma, er leystist Eyrarfloti. Þar hafði verit um sumarit, sem vant var, fjölði skipa af Nóregi. Þórólfr lét þat lið sigla allt fyrir ok gerði ekki vart við sik.

Hann sigldi einn dag at kveldi til Mostrarsunds. Þar var fyrir í höfninni knörr einn mikill, kominn af Eyri. Þórir þruma hét maðr sá, er stýrði. Hann var ármaðr Haralds konungs. Hann réð fyrir búi hans í Þrumu. Þat var mikit bú. Sat konungr þar löngum, þá er hann var í Víkinni. Þurfti þar stór föng til bús þess. Hafði Þórir farit fyrir þá sök til Eyrar at kaupa þar þunga, malt ok hveiti ok hunang, ok varit þar til fé miklu, er konungr átti. Þeir lögðu at knerrinum ok buðu þeim Þóri kost á at verjast, en fyrir því at þeir Þórir höfðu engan liðskost til varnar móti fjölmenni því, er Þórólfr hafði, gáfust þeir upp. Tók Þórólfr skip þat með öllum farmi, en setti Þóri upp í eyna. Helt Þórólfr þá skipum þeim báðum norðr með landi.

En er hann kom fyrir Elfina, þá lágu þeir þar ok biðu nætr. En er myrkt var, reru þeir langskipinu upp í ána ok lögðu til bæjar þess, er þeir áttu, Hallvarðr ok Sigtryggr. Koma þeir þar fyrir dag ok slógu manngarð, æpðu síðan heróp, ok vöknuðu þeir við þat, er inni váru, ok hljópu þegar upp til vápna sinna. Flýði Þorgeirr þegar út ór svefnskemmunni. Skíðgarðr hár var um bæinn. Þorgeirr hljóp at skíðgarðinum ok greip hendinni upp á garðstaurinn ok kastaði sér út um garðinn. Þar var nær staddr Þorgils gjallandi. Hann sveiflaði til sverðinu eftir Þorgeiri, ok kom á höndina ok tók af við garðstaurinn. Hljóp Þorgeirr síðan til skógar, en Þórðr, bróðir hans, var þar felldr ok meir en tuttugu menn. Síðan ræntu þeir þar fé öllu ok brenndu bæinn, fóru síðan út eftir ánni til hafs.

Þeim byrjaði vel ok sigldu norðr í Víkina. Þá hittu þeir enn fyrir sér kaupskip mikit, er áttu Víkverjar, hlaðit af malti ok mjölvi. Þeir Þórólfr lögðu at skipi því. En þeir, er fyrir váru, þóttust engi föng hafa til varnar ok gáfust upp. Gengu þeir á land upp slyppir, en þeir Þórólfr tóku skipit með farmi ok fóru leiðar sinnar. Hafði Þórólfr þá þrjú skip, er hann sigldi austan um Foldina, sigldu þá þjóðleið til Líðandisness, fóru þá sem skyndiligast, en námu nesnám, þar sem þeir kómu við, ok hjuggu strandhögg. En er þeir sigldu norðr frá Líðandisnesi, fóru þeir meir útleið, en þar, sem þeir kómu við land, þá ræntu þeir.

En er Þórólfr kom norðr fyrir Fjörðu, þá sneri hann inn af leið ok fór á fund Kveld-Úlfs, föður síns, ok fengu þar góðar viðtökur. Sagði Þórólfr föður sínum, hvat til tíðenda hafði orðit í förum hans um sumarit. Þórólfr dvalðist þar litla hríð, ok leiddi Kveld-Úlfr ok þeir feðgar hann til skips.

En áðr þeir skilðust, töluðust þeir við, sagði Kveld-Úlfr: "Eigi hefir því fjarri farit, Þórólfr, sem ek sagða þér, þá er þú fórt til hirðar Haralds konungs, at þér myndi svá út ganga, at hvárki þér né oss, frændum þínum, myndi hamingja at verða. Hefir þú nú þat ráð upp tekit, er ek varaða þik mest við, er þú etr kappi við Harald konung. En þótt þú sér vel búinn at hreysti ok allri atgervi, þá hefir þú ekki til þess gæfu at halda til jafns við Harald konung, er engum hefir öðrum enzt hér í landi, þótt áðr hafi haft ríki mikit ok fjölmenni. Er þat mitt hugboð, at sjá verði fundr okkarr inn síðasti, ok væri þat at sköpuðu fyrir aldrs sakar, at þú lifðir lengr okkar, en annan veg, ætla ek, at verði."

Síðan steig Þórólfr á skip sitt ok helt á brott leið sína. Er þá ekki sagt frá ferð hans, at til tíðenda yrði, áðr hann kom á Sandnes heim ok lét flytja til bæjar herfang þat allt, er hann hafði heim haft, en setja upp skip sitt, skorti þá eigi föng at fæða lið sitt um vetrinn. Sat Þórólfr heima jafnan ok hafði fjölmenni eigi minna en ina fyrri vetr.
