Avenging and bright fall the swift sword of Erin br On him who the brave sons of Usna betray'd! -- br For every fond eye he hath waken'd a tear in br A drop from his heart-wounds shall weep o'er her blade. br br By the red cloud that hung over Conor's dark dwelling, br When Ulad's three champions lay sleeping in gore -- br By the billows of war, which so often, high swelling,, br Have wafted these heroes to victory's shore -- br br We swear to avenge them! -- no joy shall be tasted, br The harp shall be silent, the maiden unwed, br Our halls shall be mute, and our fields shall lie wasted, br Till vengeance is wreak'd on the murderer's head.
