In projecting his campaign, Brown was a law unto himself, untrammelled by the accepted usages of war. The excess of his ardor and enthusiasm led him to believe that he could corrupt the rank and file of the army. In his philosophy, the daring, dangerous, adventurous men who largely composed the enlisted men of the army at that time, having no hope of promotion in the service, would become eager listeners to his proposal. Before them, he would throw open the storehouses of his prospective empire, that they might behold the volume of his treasures, and select that which they desired. His army was to be created; he had the men in view--the slaves whom he would set free--but not the officers to command them. If the enlisted men would desert from their service singly or _en masse_, and thus temporarily paralyze the United States forces, and join him, they could immediately become commissioned officers in his army and share with him the honors, the booty, and the beauty of the rich country he intended to ravage. By means of these "mighty and soul satisfying rewards" he hoped to "seduce the soldiery of the Union." The campaign of education was a stratagem.
It is not apparent that Forbes, at any time, showed a desire to quit Brown's service, or any disinclination to follow him westward. It is true that he was in arrears at one time with his literary work, but that was due to an incidental diversion of his activities in other directions--soliciting contributions and collecting money from various benevolent persons, including Mr. Greeley and Mr. Gerrit Smith. Forbes also had been making necessary arrangements for the comfort of his family--a wife and a daughter. The former being in Paris, and the latter in New York, he wisely decided, in view of the character of the pending military operations, to have the latter return to the care of her mother. Brown, who was paying the price, required results rather than explanations. It appears that Forbes had not prepared the "Manual" within the time in which he had led his impetuous chief to believe it would be forthcoming; and this had aroused an unwarranted suspicion in his mind that his subordinate was lagging. It is also true that Forbes had been indiscreet from a "military" point of view. He had talked, as one having authority, or knowingly, about the situation in Kansas, and had committed the very serious mistake of expressing a doubt that their services would be needed there before winter, which would have a tendency to discourage contributions to the "cause of freedom." In addition to all this, Brown became suspicious that the "Colonel" was ambitious, and aspired to supersede him in command; or, it may be that he became jealous because of his subordinate's brilliant accomplishments--his "military bearing" and qualifications. Mr. Sanborn confirmed Brown's distrust of him. He says that "Forbes was ambitious and apparently desirous of taking Brown's place in command." It may, however, be nearer the truth to assume that the depleted condition of the exchequer had much to do with Brown's "dissatisfaction" with Forbes.
