Capt. Van Vliet wrote his report to Gen. Pleasanton of his mission to SLC. He relayed Mormon belief that the Army's purpose was to continue previous religious persecution and would resist to the death the Army's entrance into SLC. If the Army were too large to resist, the Mormons would burn everthing and flee to the mountains. He wrote of his kind and hospitable treatment and his regret that he could not dissuade the determination to resist the Army.
