Capt. James Allen, of the U.S. army, arrived at Mount Pisgah and had an interview with Apostle Wilford Woodruff and Pres. Wm. Huntington and council. He was the bearer of a circular to the "Mormons," making a requisition on the camps of the Saints for four or five companies of men, to serve as volunteers in the war with Mexico. Capt. Allen was advised to visit the authorities of the Church at Council Bluffs.
