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. <br /> <br />Yes, monarch! though sweet are our home recollections, <br />Though sweet are the tears that from tenderness fall; <br />Though sweet are our friendships, our hopes, our affections, <br />Revenge on a tyrant is sweetest of all!<br /><br />Thomas Moore<br /><br />http://www.poemhunter.com/poem/avenging-and-bright/
