The 111th New York Infantry Regiment was organized at Auburn, New York, to answer the call by Abraham Lincoln for 300,000 more troops to fight in the American Civil War. Over the next three years, this regiment lost the fifth greatest number of men among all New York regiments.
Jesse Segoine was authorized on July 18, 1862, to begin recruiting a regiment of men within the Cayuga and Wayne Counties, New York. As Segoine was able to raise the men, he received a commission of Colonel and commander of this, the 111th New York Infantry Regiment. The regiment was raised in almost a month's time, and mustered into service in Auburn, New York, on August 20, 1862.

Over the 111th Regiment's time in service, total enrollment was 1,780 soldiers. Ten officers and 210 men were killed and mortally wounded in battle. The total of 220 men who were killed and died of wounds is only exceeded by four other New York regiments — the 69th, 40th, 48th and 121st. In the entire Union Army, that number is only exceeded by 24 other regiments. Disease and other causes took another 2 officers and 177 enlisted men. This raises the total sacrificed to reunite this nation to 404. It should be noted that 2 officers and 74 men died while in the confinment of Confederate prisons.
