Nú skilst Hersteinn frá liðinu með þrem tigum manna þangað sem hann sagði hinn síðasta náttstað verið hafa Þorvalds Oddssonar,
Now Hersteinn parts from the band with thirty men (lit: three tens of people) to-that-place which he said had been the last (ie most recent) night-quarters of Þorvaldr Oddr‘s-son,

því að hann var þá farinn af vist sinni.
because he was (had) then gone from his abode.

Nú er ókyrrt í héraðinu og mikil umræða og samandráttur liðs af hvorratveggja hendi.

Það varð til tíðinda að Hænsna-Þórir hvarf brott úr héraðinu við tólfta mann
That came for as tidings that Hænsa-Þórir disappeared (hverfa brott, Z3) out of the-district with the twelfth man (person) (ie with eleven others)

þegar hann spurði hverjir í málið voru komnir og fréttist alls eigi til hans.

Oddur safnar nú liði um dalina, Reykjardal hvorntveggja og Skorradal,
Oddr assembled now a band throughout the-dales (plural), each of the two Reykjadalrs (Dales of Steam) and Skorradalr,

og um allar sveitir fyrir sunnan Hvítá og þó hafði hann mart úr öðrum sveitum.

Arngrímr goði (priest-chieftain) assembled men (people) throughout Þveráhlíð (Side-River-Slope) and Norðurádalr (North-River-Dale) from some parts.

Þorkell ‘Rag’ assembled men (people) lower-down throughout Mýrar (Swamps) and Stafholtstunga (Staff-Wood-Tongue) and some of (the) Norðurdalr-folk he has with him

because Helgi his brother lived in Hvammr and he has him with him.

Nú safnar Þórður gellir liði vestan og hefir eigi mart lið. Hittast nú þessir allir er í voru málinu og hafa alls tvö hundruð manna,
Now Þórðr gelli ‘Roarer’ assembles a band from-(the)-west and has not many troops. Now all these who were in the-case meet-each-other and (they) have two hundred (of) men (people) in all.,

ríða nú ofan fyrir utan Norðurá og yfir á að Eyjavaði fyrir ofan Stafholt og ætla yfir Hvítá þar sem heitir Þrælastraumur.

Þá sjá þeir mannaferð mikla fyrir sunnan ána. Er þar Tungu-Oddur og nær fjögur hundruð manna.

Hittast nú við ána og hlaupa þeir Oddur af baki og verja vaðið en þeim Þórði gengur ógreitt framreiðin og vildu gjarna komast á þingið.
(They) meet-each-other by the-river and they, Oddr (and co) leap now off (horse)-back and defend the-ford but the-riding-on goes unexpeditiously (úgreiðr) for them, Þorðr (and co) and (they) would-want eagerly to make-their-way to the-assembly.

Slær nú í bardaga og verða þegar áverkar. Féllu fjórir menn af Þórði.
(It) came now to a battle (slá í e-t, Z7) and bodily-injury occurs at-once. Four men (persons) fell by means of Þórðr (or from among Þorðr’s troops? Not sure).
