- Native of County Cavan, Ireland, O'Rorke sacrificed himself and his men to save the Union right on Little Round Top.
Summoned to Little Round Top by Gouverneur K. Warren and seeing that the 4th and 5th Texas were breaking through the right flank of the 16th Michigan,
O'Rorke threw his men into the breech. O'Rorke was killed in one of the first volleys.
I'll stop by his grave today to pay my respects.
