The 30th New York Infantry Regiment, or officially "30th Regiment New York Volunteer Infantry," was an infantry regiment in the Union Army during the American Civil War from the state of New York. It was a part of the famed Eastern Iron Brigade in the Army of the Potomac.
The 30th New York was mustered into service on June 1, 1861, and mustered out of service on June 18, 1863, following expiration of its enlistment term. Col. Edward Frisby initially commanded the regiment, which was organized in Troy, New York. Originally enlisted soldiers for two-year enlistments and later received 3-year men, who were later folded into the 76th New York Infantry on May 24, 1863.
The regiment suffered 6 officers and 72 enlisted men who were killed in action or mortally wounded and 3 officers and 31 enlisted men who died of disease, for a total of 111 fatalities.[1]
At least two enlisted men kept diaries during the time they served with the 30th New York - John Gordon Morrison (Morrison was later awarded the Congressional Medal of Honor for his service in the River War) and James Reed. Both men were Irish-born residents of Lansingburgh, New York who joined the unit at the time of its creation. Their daily entries provide a great deal of information about ordinary soldiers' day-to-day experience of the first months of the war.
