I own it, it is THE premier work on the subject. It goes into detail about the early war for the Regulars and what ultimately lead tho their near extinction. It has a LOT of detail you will see no where else. As an example the 2nd MN was Brigaded w/ them for a time and the detail of why & how the animosity between the Regulars & Volunteers came about was quite enlightening. Most telling was the Regulars irritation & the different length of enlistments, enlistment bonuses & discipline.
