Ireland produced more American Civil War Generals than any other foreign country. In all 18 Irishmen acted as serving generals during the war; 12 Federal and 6 Confederate.They range from the Confederacy’s Patrick Cleburne, the highest ranking Irishman on either side, who advocated arming the slaves in return for their freedom, to the Union’s James Shields, who almost fought a duel with Abraham Lincoln before the war and took on Stonewall Jackson in the Shenandoah Valley.  This page presents a very brief synopsis of these men’s Civil War activities.
