Henry G. Boyle: Converted by Jedediah M. Grant's Preaching in Virginia, Then Served in the Mormon Battalion (1843–1847)

Henry Green Boyle (1824–1902) was born in Bluestone, Tazewell County, Virginia. In 1843, at the age of nineteen, he heard Apostle Jedediah M. Grant preaching the restored gospel in Virginia and was baptized. His family did not understand the decision, and Boyle later recalled the personal cost of leaving behind parents and everything familiar to follow the Saints.

His conversion led to a series of extraordinary callings. He served a mission in Virginia almost immediately after baptism, then moved to Nauvoo, Illinois in 1845. When the U.S. Army called for Mormon volunteers in the summer of 1846, Boyle enlisted in the Mormon Battalion — the only LDS military unit in American history. He marched roughly 2,000 miles from Iowa to San Diego, California, through desert, mountain, and wilderness, as part of the epochal march commanded by Lt. Col. Philip St. George Cooke.

After being mustered out, Boyle re-enlisted in Los Angeles, then in the spring of 1848 helped lead a group that blazed the Mormon Road — the first wagon route from Los Angeles to Salt Lake City — opening a crucial corridor for westward settlement.

Boyle's subsequent life was one of continuous faithful service: missionary work in California (1853–1857), during which he baptized future Church Presiding Bishop William B. Preston; a mission to Virginia and North Carolina (1867–1869); and finally, appointment as the first president of the new Southern States Mission (1876–1878) — a mission field to the very people and culture from which he had come.

For Latter-day Saints, Boyle's story illustrates how one moment of spiritual conversion, sparked by the preaching of the gospel, ripples outward across a lifetime of service and sacrifice. His record is one of the clearest examples of conversion as the foundational miracle of the Restoration.
