Author John P. Cullop (below) asserts that while “Irish immigration increased substantially in 1863 and 1864” and it is difficult to ascertain how many served in the American military, historian Frank L. Owsley estimates “that Ireland, England and Germany contributed over 300,000 men to Union forces . . . [and] there is no doubt that the North relied heavily on immigrant soldiers.” As early as August 1862, Secretary of State William Seward was advised to send all Federal consuls in Europe full particulars about bounties paid to volunteers. Lincoln’s army was bolstered by an estimated 150,000 Irish men, of whom over 35,000 paid lost their lives. At Fredericksburg’s Marye’s Heights in December 1862, over 41% of northern casualties were Irishmen.
An Unequal Duel
“Federal interest in the procurement of recruits from Europe was manifest early in the war. In May 1861, Henry S. Sanford, American minister to Belgium, suggested to secretary of State Seward that as the Lincoln administration apparently intended to rely primarily on volunteers for the army, it was not too early to look abroad for recruits. He reminded the Secretary that the British had received excellent service from the German Legion of Ten Thousand during the Crimean War.
On August 8, 1862, Seward sent all American embassies and consulates in Europe Circular No. 19, which was essentially an invitation to the poor people of Europe to emigrate to the US, emphasizing opportunities for wartime employment but carefully avoiding mention of possible military service. However, mercenary soldiers were uppermost in Seward’s mind, for on September 19, 1862, he wrote American consul general at Paris, John Bigelow that “to some extent this civil war must be a trial between the two parties to exhaust each other. The immigration of a large mass from Europe would of itself decide it.” Many years after the war Bigelow noted that Seward’s circular threw light “upon the mysterious repletion of our army during the four years of war, while it was notoriously being depleted by firearms, disease and desertion.”
Large numbers of Irishmen applied directly to American consuls for enlistment, but were uniformly refused as enlistment had to occur in the United States after emigration. While it was an easy matter to entice Irishmen to the US, it was equally easy to enlist them on arrival. Simply informing the penniless immigrant of the large bounties was often sufficient. Even more attractive were the larger sums offered by speculators who secured substitutes for northerners who wished to avoid Lincoln’s draft.
By April 1864, British Foreign Minister Earl Russell charged that there was strong circumstantial evidence of a well-organized Union military recruiting program in Ireland. This led to a closer scrutiny of Union activity in Ireland but did little to stem the flow of Irish emigrants in 1864.”
