DEATH OF GEN. J. C. PINCKNEY, HIS CAREER AS A SOLDIER AND IN CITY PUBLIC LIFE. Gen. Joseph C. Pinckney, Commissioner of Emigration, died at his residence, No. 27 Stuyves- ant-street, yesterday afternoon at 3 o'clock. He has been troubled for some time with a torpid liver, which, with a complication of other disorders, prostrated him. He became insensible at midnight on Thursday, and did not again regain concious- ness. Gen. Pinckney was born in 1821, in the Elev enth Ward of this City. His father, Peter Pinckney, at one time was well-to-do, but he died poor, and Joseph was thrown on his own resources. In 1859 he seciured the position of clerk in the Finance De- partment, under Controller Robert T. Hawes, and he was soon promoted. He was prominent in the organization of the Bureau of Arrears, and became its chief manager. Before entering political life, however, Mr. Pinckney had become a member of the New-York State Militia. He began as a private in the Sixth Regiment, and had gradually risen to the rank of Colonel in the regiment. When the war broke out he promptly resigned his position in the Controller's office, and was one of the first to offer the services of himself and his regiment to Gov. Morgan for the defense of the Union. The Sixth was detailed to remain in Annapolis, Md., and Col. Pinckney was placed in command of the city, which was then an important base of supplies. At the end of the three months for which it had been called into service, the Sixth returned home, and Col. Pinckney recruited the Sixty-sixth New-York Volunteers, which was attached to the First Divi- sion of the Second Army Corps, and did good sercice in the Army of the Potomac, under Gens. McClellan and Pope. While in command of the Sixty-sixth at the battle of Gaine's Mill, Col. Pinck- ney had behaved so gallantly that he was compli- mented in general orders and made Brevet Brigadier-General. He resigned his commission in the Army in 1863, having become incapacitated for duty by sickness contracted in the service. He was subsequently appointed Quartermaster-Gen- eral, in charge of the depot at Buffalo, in this State, an office which he filled until the close of the war. After a two year's trip to Europe, made neces- sary by the state of his health, he returned home in 1867, and at once renewed the political life which he had resigned to engage in the war. He had been one of the organizers of the Republican Party in the Seventeenth Ward, and has been a leading member of the Fourteenth District Republican Association since its foundation. At one time he acted as President of the association, but of late years he has represented it as a delegate in the Republican Central Committee. In the latter body he has always been recognized as an important member, and for the past five years he has acted as Chairman of the Finance Committee. In 1878 Gen. Pinckney was made Clerk of the Board of Aldermen and served in that capacity for two years. in 1875 he was elected Alderman from the Sixth District, which had up to this time been overwhelmingly Democratic. He served as Alder- man at Large during 1877 and 1878, retiring from the board on Jan. 1, 1879. In 1878 he was elected Chairman of the Republican Central Committee to succeed the late Hon. Benjamin K. Phelps, and at the conclusion of his term he was succeeded by Gen. Chester A. Arthur. He was appointed Commis- sioner of Emigration by Gov. Cornell early last year and has served in that board ever since as Chairman of the Ward's Island Committee. Gen. Pinckney has been a delegate to every Re- publican State and County convention since the war. He was a member of the Chicago Convention which nominated President Lincoln, and an alter- nate to Gen. Arthur at the last national conven- tion. He was a member of the Grand Army of the Republic since its inception. For three years he was Commander of Cameron Post. No. 79. He was Chairman of the Memorial Committee of the or- ganization in 1875 and 1876, and had been a delegate to every national and State en- campment. He was a prominent Freemason, formerly Master of a lodge, and was one of the oldest members of the Morton Commandery, Knights Templar. He was also prominent in the Order of Odd-fellows and the Benevolent Order of Elks. He jeld at one time one of the highest offices in the latter society, and delivered an oration for it when the monument was raised by the order in 1879 in Evergreen Cemetery. Gen. Pinckney was a widower and leaves one son, about 19 years of age. At his home in Stuyvesant- street, he had collected a library peculiarly rich in everything related to New-York City politics. He became so ill as to be confined to his house about the latter part of December. During his ill- ness he was attended by Dr.Carnochan.
