Early in the Valley Campaigns of 1864, including the losses at the Battle of Fisher's Hill and the Battle of Cedar Creek. Incapacitated by typhoid fever by the autumn of 1864, Imboden left the active cavalry service. Beginning on January 2, 1865, Imboden commanded Camp Millen, Georgia, then the prison camp at Aiken, South Carolina as well as other prison camps in Georgia, Alabama, and Mississippi throughout 1865 until the end of the war. He was paroled in Augusta, Georgia on May 3 of that year. Postbellum After the war, Imboden moved to Richmond, Virginia, where he resumed his work as a lawyer, serving first in Richmond and then in Abingdon, the county seat of Washington County. His brother George moved to West Virginia, where he invested in land and coal, becoming a prominent businessman and legislator. John Imboden also advocated development of Virginia's natural resources and transportation infrastructure. In 1872 he published The Coal and Iron Resources of Virginia: Their Extent, Commercial Value, and Early Development Considered. Around 1875, he moved to southwestern Virginia where he hoped to mine coal and iron ore deposits. He founded the town of Damascus, Virginia, which became a lumber center in the late 19th and early 20th century. John D. Imboden also participated in Confederate veterans activities and the Lost Cause movement. He published several articles and books about the Civil War, and also contributed to The War of the Rebellion: A Compilation of the Official Records of the Union and Confederate Armies (128 vols., 1880-1901). In 1876, he became a commissioner of the Centennial International Exposition in Philadelphia, Pennsylvania, and in 1893, he was a commissioner of the World's Columbian Exposition in Chicago. In the winter of 1879-1880, Imboden traveled to Pittsburgh, Pennsylvania, to meet with potential investors for coal operations in Wise County, Virginia. He persuaded the investors to begin operations with the region, leading to the chartering of the Tinsalia Coal Company, and later the Virginia Coal & Iron Company. Imboden then worked as a land agent for the company, securing property and mineral rights. One of the coal camps in Wise County, Imboden, is named after him.
