Monaghan was born in Ireland in 1840 and immigrated to the United States when he was 10 years old, settling in Minersville, later becoming a mine laborer.
During the summer of 1861, at the age of 21, he enlisted in the military joining Company F, 48th Infantry Pennsylvania Volunteers in Pottsville, rising to the rank of sergeant.
During the Civil War, Monaghan would be wounded three times, at the Second Bull Run, the Wilderness, and at Petersburg.
On June 17th, the 48th would attack Confederate Lines surrounding Petersburg that would eventually lead to the surrender of retreating Confederate forces. For this, he was awarded the Medal of Honor on December 1st, 1964. Major General George Meade personally handed him the medal on December 16th.
After the war, Monaghan would return to Minersville and join the National Guard, ultimately rising to the rank of Lieutenant Colonel.
Following his discharge, Monaghan served as a school teacher and superintendent of Girardville Public Schools from 1873 to 1916. Patrick Monaghan died in 1917 at the age of 74. Monaghan was buried at St. Joseph's cemetery in Girardville.
