Hi Everyone, There were two regiments of New York Volunteers who fought in the Mexican-American War of 1846-1848. Each regiment contained ten companies of men of varying sizes. Each regiment had roughly 800 - 1,000 men. ---------------------------------------------------- The First Regiment of New York Volunteers is the one best known to California researchers. It is sometimes referred to as "Stevenson's Volunteers" for Jonathan Stevenson, the Colonel who recruited the regiment in New York in 1846. The ten companies comprising the First Regiment were mustered out of the service of the United States as follows: By Lieut. Jas. A. HARDIE (Late Major of the Regiment), 3rd U.S. Artillery Company "C," Captain J.E. BRACKETT, at San Francisco, August 15th, 1848 Company "K," Captain K.H. DIMMICK, at San Francisco, August 15th, 1848 Company "H," Captain J.B. FRISBIE, at San Francisco, August 25th 1848 By Captain A.J. SMITH, 1st U.S. Dragoons Company "F," Captain F.J. LIPPITT, at Santa Barbara, Sept. 8th, 1848 Company "E," Captain Nelson TAYLOR, at Santa Barbara, Sept. 18th, 1848 Company "G," Captain M.R. STEVENSON, at Santa Barbara, Sept. 18th, 1848 Company "I," Captain W.E. SHANNON, at Santa Barbara, Sept. 25th, 1848 By Captain Henry S. BURTON (late Lieut. Col. of the Regiment), 3rd U.S. Artillery Company "A," Captain S.G. STEELE, at Monterey, Oct. 23rd, 1848 Company "B," Captain H.C. MATTSELL, at Monterey, Oct. 23rd, 1848 Company "D," Captain H.M. NAGLEE, at Monterey, Oct. 24th, 1848 The Field Officers of the First Regiment were mustered out of servicce by Captain H.S. BURTON, at Monterey, CA, Oct. 26th, 1848. The First Regiment saw action in Alta and Baja California. -------------------------------------------------------- The Second Regiment of New York Volunteers were under the command of Colonel Ward B. BURNET. This regiment of ten companies saw action on mainland Mexico. I haven't read very much about the battles on mainland Mexico, but it appears that the Second Regiment saw action on the Texas border and then progressed into New Mexico and northern Mexico. Judging by the injuries incurred by officers of the 2nd Regiment, they were an intrical part of the major battles in Mexico, alongside the regular U.S. Army. [For those whose ancestors were not a part of the First Regiment, it looks like they may have been members of the Second Regiment.] I will post the officers of the Second Regiment in a separate email. [FYI, I have no additional information about any of the soldiers other than what I will be posting.] Hope this helps, Anita C. Monterey County
