OBITUARY. GEN. THOMAS C. DEVIN. Gen. Thomas C. Devin, Colonel command- ing the Third Regiment of Cavalry, died at his resi- dence, No. 219 East Forty-ninth-street yester- day morning. His death was due to a compli- cation of disorders caused by exposure and im- proper food during a long period of hard service in Arizona Territory, while holding the rank of Lieu- tenant-Colonel of the Eighth Cavalry. About eight months ago he was promoted to the command of the Third Regiment, and was granted five months leave of absence. He left this City to return to his post at Fort Laramie on Nov. 28 last, and on Feb. 21 he was compelled to ask a "sick leave of absence." After returning home, he was confined to his bed and never recov- ered. Gen. Devin was born in this City on Dec. 10 1822, and received his education in the public schools. He learned the painter's trade, and followed that avocation until the breaking out of the re- bellion in 1861. He had always had an admi- ration for a soldier's life, and held a commission as Lieutenant-Colonel of the First Cavalry, National Guard of this State, at that time. He went to the field at the head of a detachment of 800 men. On June 26, 1862, his regiment joined the Army of the Potomac, and performed picket duty along the Rappahannock and in the Shenandoah Valley for several months. In the Fall of 1862, when the cavalry corps was formed, Gen. Devin was placed in command of the Second Brigade, First Division. Shortly after the battle of Cedar Creek, in the Au- tumn of 1864, he was promoted to Brigadier-General. In the Spring of 1865 he was placed in command of the First Division, and at the Battle of Five Forks his division was foremost. His cavalry dismounted, charged upon the enemy, and captured their guns. For this brave service Gen. Sheridan presented a handsome silk flag to the division, upon which were arranged representations of five forks, with five prongs each, in the form of a star. During the war Gen. Devin participated in 72 battles. Soon after the close of the war, Gen. Devin, Gen. Merrit, and Gen. Custer were commissioned Lieutenant-Colonels in the regular Army, and the former was assigned to duty with the Eigth Cavalry, which was then stationed in Arizona Territory. Although there was considerable jealousy engendered in some quarters immediately after the war through the acts of the Government in promoting volunteer officers to the regular service, no such feeling was ever manifested toward Gen. Devin from the fact that it was gener- ally conceded that he had nobly earned his promo- tion. He leaves a wife and one child--a daughter. His funeral will take place to-morrow at St. Francis Xavier's Church, West Sixteenth-street, at 10 A.M. The military order, Loyal Legion of the United States, of which he was a mem- ber, will attend the funeral in a body. At a meeting of this organization at Delmonico's on Wednesday night, a committee of three, comprising Col. H.M. Porter, Commander Ransom and Chap- lain Ferris, was appointed to visit Gen. Devin, yes- terday, but it was not expected that his death was so near at hand. Chaplain Ferris called in the morn- ing just before the death of his old comrade. The other members of the committee visited the residence of the deceased officer last evening.
