As medical officer he was present at the battle of Pittsburg Landing, Tennessee; siege of Corinth, Mississippi; battle of Perryville, Kentucky, and of Murfreesboro, Tennessee, at which battle he rode in person with that regiment in its now historic charge.  While on the battlefield, during the engagement, and in search of a wounded officer, he captured a Confederate soldier, disarmed him and made him a prisoner of war. During the first half of 1863 he was in a charge of the Fourth regiment, United States cavalry, at Snow Hill, Tennessee, in a charge of that regiment at Franklin, Tennessee.  During August and several subsequent months he was on duty at the United States general hospital at Chester, Pennsylvania.

During the summer and autumn of that year he was in charge of a small-pox hospital; and also a post hospital at Columbia, Tennessee. At the advance of the Confederate General Hood, upon Nashville, when it seemed impossible to prevent the sick and wounded, in the field hospital at Columbia, Tennessee from falling into the hands of the enemy, he was detailed to remain "in charge" of the sick and wounded; and, but for the fact that they were subsequently removed under cover of the night, he, with them, would have been made a prisoner of war. He was present at the battle of Nashville. He was on duty at the Cavalry Corps hospital, at Gallatin, Tennessee, during the greater part of January and February, 1865. During the spring and the greater part of the summer of that year he was "surgeon in charge" of Hospital No. 16 at Nashville, which had a capacity of four or five hundred beds, and a staff of five or six medical officers. After the close of the war, when the general hospitals were closed, he was ordered to sell, at auction, the unserviceable property of Hospitals No. 8. and No. 16, and of one or two others, and the sum of several thousand dollars, realized there from, reverted to the treasury of the United States. During the greater part of the summer and autumn of 1865 he was in charge of Post Hospital at Clarksville, Tennessee. On the 3rd of November, 1865, he was mustered out of the service with the brevet rank of captain of volunteers, but he was assigned to duty as acting assistant surgeon, United States army, at the headquarters of Major-General George H.Thomas at Nashville, and at once made post surgeon, or "physician in attendance upon the officers and their families." From 1866 to 1892 Dr. Comfort was with detachments of the army stationed at various forts on the frontier,having visited nearly every territory in the west, traveled over the plains with the soldiers in pursuit of hostile Indians, in his capacity of assistant surgeon of the army, and as such rendered much service.  There is scarcely a fort from the Dakotas to the Indian Territory and Arizona where he has not been stationed, and scarcely a trail over the vast territory of the far west that he has not followed.
