There were two newspapers in Troy with which Rev. Henry Highland Garnet was involved, the Clarion and the National Watchman. There is not a lot known about either newspaper, not even the years in which they were in operation; different texts make different claims.The 1865 publication of A Memorial Discourse; by Henry Highland Garnet, Delivered in the Hall of the House of Representatives, Washington City, D.C. on Sabbath, February 12, 1865 stated of Garnet, "In 1839-40 he published, at Troy, a weekly paper characteristically named the "Clarion," throwing out in type the bugle notes wherewith he was wont by voice and mien to lead the people to battle against their surrounding, almost overwhelming, oppressions." The Afro-American Press and Its Editors (1893) by Irvine Garland Penn claimed that the National Watchman began in 1842 and that when it ceased to publish the Clarion began. Of the Clarion, Penn wrote "This paper, while not failing to treat the most momentous of questions—American Slavery—with weighty argument and skillful debate, was run, we are informed, mostly in the interest of the religious and moral improvement of his race, to whose wellfare [sic] he was wedded."Upon initial searches, the only mentions of the National Watchman in other newspapers seem to be from 1847. Thus it would appear that the Clarion was the first of the two, not the other way around as is often claimed. It must have run from April 1843 (if not earlier) to at least October 1843.While the newspaper was not published in Lansingburgh, it almost certainly would have been of some interest there for any number of reasons, including the existence of an African Methodist Episcopal Zion Church in the Village of Lansingburgh at the time.

[Henry Highland Garnet] did find time to work on a newspaper he called the Clarion, a sporadically published journal that replaced the Troy Herald of Freedom. The paper was the total expression of Garnet's views: the language, the style and the rhetoric were all his. In the October 19, 1843 issue of the Clarion, he wrote how the nation must be delivered from the hands of "blood-sucking slaveholders," who apply their "suction to the pockets of every free laborer." Although the Clarion was short-lived and was not a high quality newspaper, Gerrit Smith, who helped support it, welcomed the Clarion as an "important new voice."Pasternak, Martin B., "Rise now and fly to arms: the life of Henry Highland Garnet."

[Citing "Troy Clarion, October 19, 1843; Gerrit Smith to Henry Highland Garnet, April 4, 1843, Gerrit Smith Papers, New York Public Library." The reference to "the Troy Herald of Freedom" might mean the Clarion did follow another newspaper, just not the National Watchman, or it might be an error. There was a Herald of Freedom published in Concord, New Hampshire 1835-1846.]After reading the first number of the Clarion, Gerrit Smith, the abolitionist, wrote to Garnet: “I welcome the appearance of this new and free spirited paper. . . . So long as the free colored people of this country continue to run after and hang upon our great men in Church and State, they will be degraded."MacMaster, Richard.

Things look well in the Empire State. [...]Rev. C. T. Torrey, of the Albany Patriot, is laboring with tongue and pen in the cause. He says, in regard to the Franckean Synod:—"On Saturday last, we had the pleasure of addressing this efficient body, at their annual meeting at West Sand Lake, in regard to the duties and responsibilities of Christian ministers and churches to the slaves of our land. A large audience listened with gratifying attention." The President, Rev. P. Wieting, said, in reply to a question, that the churches connected with this body would not receive members from, or dismiss them to, slaveholding churches."Good Anti-Slavery resolutions were passed by the Synod, as the result of Mr. Torrey's address. Mr. T. thus speaks of a new paper issued by our colored friends of Troy:—"'THE UNITED STATES CLARION,' is the title of a temporary publication, issued at Troy, New York, by a committee of our colored friends, appointed at a meeting in New York,to call a National Convention at Buffalo. The convention will meet on the 3d Tuesday in August. The names of the committee guaranteee an effective movement. They are, Henry H. Garnet, Chairman; C. B. Ray, T. S. Wright, Thomas Paul, J. H. Townsend, William Rich, J. F. Murray, A. G. Beman, J. C. Morel, William P. Johnson, J. W. Duffie, Abraham D. Shadd, James E. Crawford, Committee.The friends in Albany, Troy, Schenectady, and other places, are moving in the matter with great spirit."Emancipator and Republican [Boston, MA]. June 22, 1843: 30. [Holdings of the Albany Patriot are scarce. Due apparently to the oldest surviving issues in archives in New York dating from 1844, the New York State Newspaper Project did not even record the newspaper as having existed in 1843. http://www.nysl.nysed.gov/nysnp/all/401.htm ]
UNITED STATES CLARION.
The above is the title of a new paper, to be published semi-monthly, at Troy, N. Y., the first number of which has been handed us by a friend.The following paragraph bears the impress of that noble specimen of humanity, HENRY H. GARNET. After quoting from a New Orleans paper, an article on the subject of TEXAS, abolition, &c., the editor says:"Our fervent and constant prayer to Almighty God is, that the sword may never depart from that guilty land, nor commotion cease, until the spirit of liberty shall govern the people of Texas. They are alarmed at the stately steppings of British freeeom [sic]; and well may they be. We do hope that such a mass of political and moral putrefaction as Texas is, may never be stuck upon the Union. We are bad enough now, and we are certain if that "valley of rascals" is united to us, we shall go with Ephraim, and Ichabod be written upon the face of our affairs. Texas cannot prosper. They buy up crippled and worn-out slaves at half-price, and work them to death. Inglorious wretches! Let the earthquake shake them."Emancipator and Republican [Boston, MA]. June 29, 1843: 34.
