Thomas Mogan Biography and Civil War Narrative

Thomas Mogan was born about 1837 in Ireland. He came to America in 1853 and enlisted in the 5th Minnesota Volunteer Infantry Regiment on January 7, 1862, at Stillwater, Washington County. On April 30, 1862, as the regiment was being organized, Mogan was made a Sergeant in the company. Company K and six other companies of the 5th Minnesota were sent south in early may and reported to General John Pope near Corinth, Mississippi, on May 24, where they were attached to the Second Brigade (Plummer/Loomis), Second Division (Stanley), Army of Mississippi (Pope). Just four days later they were engaged in the Battle of Farmington, a smaller engagement that was part of the larger Siege of Corinth (May 26-30). Later in that first year of service, the 5th Minnesota participated in the (Second) Battle of Corinth on October 3 and 4.

In March 1863, First Sergeant Patrick J. Brennan deserted the regiment at Memphis, Tennessee. It was most likely at this point that Thomas Mogan was promoted to First Sergeant. Soon after, the 5th Minnesota was attached to 2nd Brigade (Mower), 3rd Division (Tuttle), 15th Army Corps (Sherman), Army of the Tennessee (Grant). They participated in the Siege of Vicksburg from May 18 to July 4.

On February 29, 1864, 1st Sergeant Thomas Mogan re-enlisted in the 5th Minnesota with credit given to Stillwater, Washington County.  The 5th Minnesota participated in the Red River Campaign from March 10 to May 22. Veterans who had re-enlisted received a furlough from June 17 to August 17. On December 15 and 16 the Regiment participated in the Battle of Nashville, playing a key role in both days of fighting.

From March 7 to April 12, 1865, the Fifth Minnesota took part in the Campaign against Mobile, Alabama and its Defenses. While there, on March 31, 1865, 1st Sergeant Thomas Mogan was promoted to First Lieutenant, replacing Francis G. Brown who had been promoted to Regimental Quartermaster on March 18. Mogan was mustered out with the Regiment on September 6, 1865.

Returning to Minnesota after the war, appears as a resident of Stillwater Township, Washington County, in the 1890 Special Census for Veterans, and as a resident of Minneapolis, Hennepin County, in the 1895 and 1905 Minnesota Census records. The 1900 U.S. Census shows him living in the Minnesota Soldiers Home. He is also listed as a participant in the funeral of comrade James Mahoney on Thursday, November 29, 1888, in Stillwater.Thomas Mogan death announcement in the Princeton Union newspaper
