Theodore F. Brown
Company D

Theodore Frelinghuysen Brown was born in Fayette County, Illinois on May 12, 1835. He married his New York-born wife Fannie in 1856 or 1857. Their first son Harry was born in Wisconsin in 1858. The 1860 census found the small Brown family living in Freeport in Stephenson County, Illinois. Theodore was listed as making his living as a merchant. A daughter Harriet was born in 1861. Brown signed up for military service on September 20, 1861. He was enrolled initially as a second lieutenant but was quickly promoted to first lieutenant.

In July, upon the resignation of Captain Ezra Brainard of Company D, Brown was promoted to the captaincy of Company D. He was officially mustered as captain on November 1, 1862, and held that position until he was discharged on May 15, 1865. In February, 1862, when the Fifty-First had barely reached "the field" at Cairo Brown and Henry Wescott, captain of Company A, returned to Chicago, with men detailed from the regiment, in charge of Confederate prisoners from Fort Donelson.

On March 14, 1862, Brig. Gen. Eleazar A Paine, who was then in command of the brigade of which the Fifty-First Illinois was a part, preferred charges against Brown, "In this that... he did... at a dwelling house in the town of New Madrid... feloniously steal and take away certain goods, to wit one colt, then and there, being the property of one Mrs. Craig." The stolen goods were worth five dollars. As of March 28, 2007, we are in the process of securing the court martial records to see what the verdict of the court was. The episode apparently did not damage Brown's credit with his regimental superiors, for, whenever there were recruiting details from the regiment back home to Illinois, Brown was part of them. In July 1862, after the Island No. 10 and Farmington/Siege of Corinth campaigns, when the regiment was still trying to recruit up to something like full strength, Brown was sent north to Chicago. During the regiment's reenlistment furlough in February and March, 1864, Brown—having been wounded in the head five months before—again had key recruiting duties and tended to the business of renting and paying for the rendezvous quarters for recruits in Chicago. When the regiment headed back to Tennessee, Brown stayed on to finish up the administration of the recruiting effort in Chicago and Springfield, and then hurried to rejoin the regiment.

Brown was wounded at Chickamauga on September 19 or 20, 1863. Lt. Col. Samuel Raymond's casualty report said Brown was wounded in the side and head. In a note of December 12, 1863, Brown himself wrote simply, "I was wounded in the head at the Battle of Chickamauga." He was moved away from the battlefield hospital quickly enough to escape capture by the Confederate cavalry that took the hospitals, many of the wounded of the Fifty-First, and numerous hospital attendants from the regiment captive on September 20. He went home on furlough for 30 days. On October 11, 1863, from Beloit, Wisconsin, Brown wrote to Adjutant Henry Hall's mother (Hall was seriously wounded at Chickamauga), "You do not know how often I have thought of Henry this week, for I have been so happy with my little ones & enjoying the rest peace and comforts of home." Between battles, between the campaigns of 1863 and 1864, Brown won this respite with his family, 700 miles away from Chickamauga. Upon returning to the regiment, Brown found that he was "not as strong" as he thought and thought he also had a "hemorrhage of the lungs"—a portent of future health issues. Assistant Medical Director Major Thurston sent Brown to the Officers' Hospital.

On June 27, 1864, in the charge at Kennesaw Mountain Brown was again wounded by a gunshot, this time to the left forearm. It took the wound forever to heal; Brown filed several requests for extension of leave (from Beloit, Wisconsin), due to slow healing of the wound. On November 11, 1864, almost five months after the wound, his physician certified, "He is suffering from gun shot wound of the left forearm, upper 3d, involving both bones and subsequent gangrene of the parts. Wound still open and discharging freely. He has had pyemia and his general health is still much impaired though improving since last extension was granted." He never returned to duty with the regiment.

On June 22, 1867, Brown received brevet promotions to Major, Lieutenant Colonel, Colonel, and Brigadier General for "gallant conduct at the battle of Kenesaw Mountain, Georgia, and for gallant and meritorious services during the war." We have yet to determine the nature of the "gallant conduct" at Kennesaw Mountain. Many, many soldiers received brevet promotions—indeed, it was once moved at a meeting of the Society of the Army of the Cumberland in Chicago that everyone stop using their brevet titles because no one knew any longer who anyone was. (We are engaged in a search to determine if there was a single particularly dramatic act of courage at Kennesaw that underpinned Brown's brevets or rather persistent courage during long and many months of steady service.)

Brown was mustered out of the service officially on June 7, 1865, for reasons of disability attendant upon his wounds and war ailments. He settled in Chicago. The 1870 census found him doing quite well as a hardware manufacturer. He and Fannie had four children. He was periodically plagued by respiratory difficulties for the rest of his life. In September 1875, Brown wrote to the Society of the Army of the Cumberland to explain his first absence from the Society's reunion that year. He wrote from the Rocky Mountains explaining that he had had to escape Chicago for a stay in Colorado, "My lungs have given out to such a degree a change in climate was absolute." By 1880, he was no longer just taking the cure in Colorado but had settled in Denver. His occupation was listed as "railroad agent" in the census records.

He spent his last years at 1801 Warren Avenue in Chicago, about twenty blocks due west of the downtown "Loop". He died, according to his death certificate, of "senile pneumonia"—his lungs again: "the lungs are attacked by a low, creeping, sneaking inflammation", according to a contemporary medical volume—on December 22, 1909 and was buried in Chicago's Graceland Cemetery, Section G, Lot 220.
