On July 2nd 1863, minutes before the Irish Brigade would charge the Wheatfield at Gettysburg, Father William Corby gave absolution to the men. Corby would later become President of Notre Dame University and the following quote from Col. St. Clair Mulholland comes from their web page on Corby:
Colonel St. Clair Mulholland was attached with the Irish Brigade and later gave this account of Corby’s famous absolution [Originally published in the Philadelphia Times, reprinted in Scholastic, April 3, 1880, pages 470-471]:
There is yet a few minutes to spare before starting, and the time is occupied in one of the most impressive religious ceremonies I have ever witnessed. The Irish Brigade, which had been commanded formerly by General Thomas Francis Meagher, and whose green flag had been unfurled in every battle in which the Army of the Potomac had been engaged from the first Bull Run to Appomattox, was now commanded by Colonel Patrick Kelly, of the Eighty-eighth New York, and formed a part of this division. The brigade stood in columns of regiments closed in mass. As the large majority of its members were Catholics, the Chaplain of the brigade Rev. William Corby, CSC, proposed to give a general absolution to all the men before going into the fight. While this is customary in the armies of Catholic countries of Europe, it was perhaps the first time it was ever witnessed on this continent… Father Corby stood upon a large rock in front of the brigade, addressing the men; he explained what he was about to do, saying that each one would receive the benefit of the absolution by making a sincere Act of Contrition, and firmly resolving to embrace the first opportunity of confessing his sins, urging them to do their duty well, and reminding them of the high and sacred nature of their trust as soldiers and the noble object for which they fought. The brigade was standing at “Order arms,” and as he closed his address, every man fell on his knees, with head bowed down. Then, stretching his right hand towards the brigade, Father Corby pronounced the words of absolution. The scene was more than impressive, it was awe-inspiring. Near by, stood General Hancock, surrounded by a brilliant throng of officers, who had gathered to witness this very unusual occurrence and while there was profound silence in the ranks of the Second Corps, yet over to the left, out by the peach orchard and Little Round Top, where Weed, and Vincent, and Haslett were dying, the roar of the battle rose and swelled and reechoed through the woods. The act seemed to be in harmony with all the surroundings. I do not think there was a man in the brigade who did not offer up a heartfelt prayer. For some it was their last; they knelt there in their grave-clothes — in less than half an hour many of them were numbered with the dead of July 2.
