It ought to be said here in justification of the course of the people of Nauvoo, that very good evidence existed to the effect that the whole difficulty connected with the arrest of Joseph at Dixon on the old Missouri charges of "treason, arson," etc, etc., was a political scheme planned with a view of securing the Mormon vote for the Whig party. The _Illinois State Register_ in July published the following on the subject of the arrest of the Prophet at Dixon, to justify the charge it made that the whole affair was but a Whig plot to secure the Mormon vote: The public is already aware that a demand was lately made upon the governor of this State for the arrest of Joseph Smith, and that a writ was accordingly issued against him. We propose now to state some of the facts, furnishing strong grounds of suspicion that the demand which was made on the governor here was a manoeuvre of the Whig party. 1st. A letter was shown to a gentleman of this city, by the agent of Missouri, from the notorious John C. Bennett to a gentleman in one of the western counties of that State, urging the importance of getting up an indictment immediately against Smith, for the five or six years old treason of which he was accused several years ago. 2nd. This charge had been made once before, and afterwards abandoned by Missouri. It is the same charge on which Smith was carried before Judge Douglass and discharged two years ago. After that decision, the indictment against Smith was dismissed, and the charge wholly abandoned. 3rd. But in the letter alluded to, Bennett says to his Missouri agent, Go to the judge, and never leave him until he appoints a special term of court; never suffer the court to adjourn until an indictment is found against Smith for treason. When an indictment shall have been found, get a copy and go immediately to the governor, and never leave him until you get a demand on the governor of Illinois for Smith's arrest; and then dispatch some active and vigilant person to Illinois for a warrant and let him never leave the governor until he gets it; and then never let him come back to Missouri without Smith. 4th. A special term of the circuit court of Daviess County, Missouri, was accordingly called on the 5th day of June last. An indictment was found against Smith for treason five years old. A demand was made and a writ issued, as anticipated, by the 17th of the same month.
