Due to the unhealthful condition of the place when the people first arrived at Commerce, many were taken sick with malaria fever, and were nigh unto death. Some of the refugees were sheltered only by tents and wagon covers, for there had been little time, and less means, by which houses, even of logs, could be built. On the morning of July 22, 1839, the Prophet arose from his own bed of sickness and being filled with the Spirit of the Lord, he went forth along the river bank healing all who were afflicted. Among the number were Henry G. Sherwood and Benjamin Brown, who appeared in a dying condition. He later crossed over the river to Montrose and healed Brigham Young and a number of other brethren of the twelve, and took them along with him to assist him in this ministry. What took place in Iowa is thus related by Elder Wilford Woodruff:
"After healing all the sick upon the bank of the river as far as the stone house, he called upon Elder Kimball and some others to accompany him across the river to visit the sick at Montrose. Many of the Saints were living at the old military barracks. Among the number were several of the twelve. On his arrival, the first house he visited was that occupied by Elder Brigham Young, the president of the quorum of the twelve, who lay sick. Joseph healed him, then he arose and accompanied the Prophet on his visit to others who were in the same condition. They visited Elder W. Woodruff, also Elders Orson Pratt and John Taylor, all of whom were living in Montrose. They also accompanied him. The next place they visited was the home of Elijah Fordham, who was supposed to be about breathing his last. When the company entered the room the Prophet of God walked up to the dying man, and took hold of his right hand and spoke to him; but Brother Fordham was unable to speak, his eyes were set in his head like glass, and he seemed entirely unconscious of all around him. Joseph held his hand and looked into his eyes in silence for a length of time. A change in the countenance of Brother Fordham was soon perceptible to all present. His sight returned, and upon Joseph asking him if he knew him, he, in a low whisper, answered, 'Yes.' Joseph asked him if he had faith to be healed. He answered, 'I fear it is too late; if you had come sooner I think I would have been healed.' The Prophet said, 'Do you believe in Jesus Christ?' He answered in a feeble voice, 'I do.' Joseph then stood erect, still holding his hand in silence several moments; then he spoke in a very loud voice, saying: 'Brother Fordham, I command you in the name of Jesus Christ to arise from this bed and be made whole.' His voice was like the voice of God, and not of man. It seemed as though the house shook to its very foundations. Brother Fordham arose from his bed and was immediately made whole. His feet were bound in poultices, which he kicked off, then putting on his clothes, he ate a bowl of bread and milk, and followed the Prophet into the street."
