uW Translation Notes:

Note 1 topic: writing-pronouns

וַ⁠יִּפְנ֞וּ וַ⁠יָּנֻ֤סוּ & וַ⁠יְעֹֽלְלֻ֨⁠הוּ֙

and,turned and,fled & and,cut_down,them

The first they refers to the remaining Benjaminite soldiers, while the second they refers to the Israelite soldiers. It may be helpful to clarify this for your readers. Alternate translation: [And the remaining Benjaminite soldiers turned and fled ... And the Israelite soldiers gleaned]

Note 2 topic: figures-of-speech / metaphor

וַ⁠יְעֹֽלְלֻ֨⁠הוּ֙ בַּֽ⁠מְסִלּ֔וֹת חֲמֵ֥שֶׁת אֲלָפִ֖ים אִ֑ישׁ

and,cut_down,them in/on/at/with,highways five thousand (a)_man

The author is speaking as if these men were leftover crops that the Israelite soldiers gleaned. Your language may have a comparable expression that you can use in your translation. You could also use plain language. Alternate translation: [And they picked off another 5,000 men along the pathways] or [And they killed another 5,000 men along the pathways as they were trying to flee]

Note 3 topic: writing-pronouns

וַ⁠יַּדְבִּ֤יקוּ אַחֲרָי⁠ו֙ עַד־גִּדְעֹ֔ם וַ⁠יַּכּ֥וּ מִמֶּ֖⁠נּוּ אַלְפַּ֥יִם אִֽישׁ

and,pursued after,them until Gidˊom and,struck_down from=him/it thousand (a)_man

The pronoun they refers in both instances to the Israelite soldiers, and the pronoun him refers in both instances to the remaining Benjaminite soldiers. It may be helpful to clarify this for your readers. Alternate translation: [And the Israelite soldiers pursued closely after the remaining Benjaminites unto Gidom, and the Israelites killed 2,000 more of the Benjaminites]
