As someone who enjoys learning about regiments, it should not come as a surprise that one of my favorite books is William F. Fox’s Regimental Losses In The American Civil War, 1861-1865 (1898). Yes, it is old-fashioned and the writing can be overwrought, but there is much of interest between its covers. The heart of the book consists of mini-histories of what Fox deemed “Three Hundred Fighting Regiments” in the Union army. As he explained at the beginning of the section, “It is not claimed that these are the Three Hundred Fighting Regiments of the Army; but, that they are three hundred regiments which evidently did considerable fighting. There were, undoubtedly, others which did equally good, or, perhaps, better fighting, and their gallant services will be fully recognized by the writers who are conversant with their history. But, for lack of other information, this chapter deals only with those which sustained the heaviest losses in battle” (p. 122).
Recently, I perused the section describing Fox’s Three Hundred Fighting Regiments to determine which ones served at some point in the trans-Mississippi. A total of twenty-three of the three hundred Union regiments or 7.6% of the total saw duty in the trans-Mississippi. This posting marks the start of a new series briefly highlighting the activities of Twenty-three Fighting Regiments of the trans-Mississippi.
