We've already seen that is (masculine) has an accusative iom. Likewise, the masculine plural ies has an accusative iens, jens. "To go" is gwah, gwa:, which conjugates like poh or stah. "Soldier" is soldat, sol'dat. Translate now : "They used to go with the soldiers", knowing that all those soldiers are male, and without the personal pronoun before the main verb.
