Few brigades of the Civil War can boast of a record as distinguished as that of New York's 69th, yet it has never fully received the attention warranted by its record of military excellence, distinctive reputation, and the unusual perspective its members brought to the Civil War. In fact, the 69th was engaged in nearly every major action of the eastern theater; its military reputation was well deserved and its combat casualties, which are some of the highest of the war, are testimony to the soldiers' collective bravery and patriotism.

In his post as war correspondent for the New York Herald, Capt. David Power Conygham was required to be an eyewitness to the many battles on which he reported - some of the experiences he would later describe when writing the history of the Irish Brigade. Conygham's account of the Irish Brigade is one of the best - filled with vivid accounts of battle, wit and humor, and an appendix of scrupulously gathered biographical data on the men who served the unit.
