The convention was represented, at Chatham, as being a meeting for the purpose of organizing a Masonic (colored) lodge; it met May 8th, at 10 o'clock A. M. Only Brown's party and thirty-four colored men were present. Richard Realf, in his testimony before the Mason Committee, said that Brown opened the convention with an explanation of the purposes for which it had been called. That he spoke of the manner in which he had qualified himself for leadership--by a tour of the European continent, inspecting all fortifications, especially all earthwork forts, that he could find, intending to apply such knowledge, with modifications and inventions of his own, to the warfare he now proposed to undertake. "He spoke of his studies of Roman warfare, and of Schamyal the Circassian chief, and of his knowledge of conditions in Hayti, and of Toussaint L'Ouverture." He said that he expected all the free negroes in the Northern States to flock to his standard, as well as the negroes of the Southern States. Mr. Realf further stated that "no salaries were to be paid to the officers" under this constitution. That it was "purely out of that which we supposed to be philanthropy--love for the slave."[296] After the address Brown produced a copy of the "Provisional Constitution." The articles were read and adopted unanimously. Each person present then signed the constitution, and swore allegiance to the Provisional Government.[297] The nature and purposes of Brown's invasion of Virginia, in October, 1859, are disclosed in the forty-eight articles contained in this remarkable historical document.[298] At a meeting held in the evening, John Brown was elected commander-in-chief and John H. Kagi. secretary of war. The balloting for offices was continued on Monday, May 10th, and Richard Realf was elected secretary of state, George B. Gill, secretary of the treasury, Owen Brown, treasurer, and Osborn P. Anderson and Alfred M. Ellsworth, colored, were elected members of Congress.
