assailant

But he though blind of sight, / Despis'd, and thought extinguish'd quite, / With inward eyes illuminated, / His fiery virtue roused / From under ashes into sudden flame, / And as an evening dragon came, / Assailant on the perched roosts / And nests in order ranged / Of tame villatic fowl, but as an eagle / His cloudless thunder bolted on their heads.
