Not a cavalry book per se, this book by John P. Langellier is an ambitious, and partially failed, attempt to catalog and describe the U.S. Army uniforms between 1848 and 1873.
The book has a very large content, as would be expected from a tome attempting to describe this particular period. It features numerous photographs, many of items that an average student would probably never see. In this sense, the book can be a valuable asset. It also contains appendices containing uniform regulations for this period, including some interesting plates. A reader who wanted to investigate any particular uniform item would likely find it somewhere in the book.
The problem, however, comes in that the book is poorly organized and the content does not flow well. In this manner, it is confusing. A careful reader would be able to go back and forth and determine the issuance history of any one item, but it is a chore. It is almost as if the book was halted before editing had really began.
A minor caveat, the Chinese printer failed to get the dates in the title correct, and it purports, on the dust jacket, to cover the period from 1848 to 1973, an impossably large period of time. Unfortunately the book has showed up in at least one catalog with this incorrect title.
