I checked out Lurena Moses' narratives, and can flesh them out a little for you.

First, Mrs. Moses' first statement.
--She is incorrect that the first instance of the soldiers coming to her home to inquire if her husband was hiding happened during 1864, as subsequent events in her statement clearly identify this as 1863.
--Also, other clues she offers seem to identify those soldiers as member of the 25th Missouri Infantry Regiment, which was stationed in her area between March and June 1863.
--Regarding the soldier's statement that they had hung one woman already was probably bravado to get Mrs. Moses to be cooperative, but a number of the soldiers of the 25th acquired a bad reputation for atrocities while stationed in this area. However, hanging a woman was not recorded, and would have acquired enough notoriety to appear in the records--particularly in the newspapers of this region.
--Mrs. McCoy's "Colonel Hardy" was very probably Colonel Chester Harding, the commander of the 25th, and his headquarters was in St. Joseph at this time.
--Incidentally, she was arrested May 17 according to the newspaper article "A She Adder," in the St. Louis "Daily Missouri Republican," of May 22 1863. This is probably also the unflattering news article Mrs. McCoy referred to later in her story.
--Since her arrest took place before the Richfields fight of May 19, the details she presented she had to gather from others, but they had to be participants since those details are "spot on" accurate.
--I drew a blank on Major Bassetts, but he was not an officer of the 25th that I could tell. On Bassetts, I see that Union Major General Samuel R. Curtis, the commander of the Dept. of the Missouri, did write to a "I. M. Bassett, Esquire" at St. Joseph on March 1, 1863, so that must be the same man Mrs. McCoy referred to in her narrative. I simply don't know the man's position, title, or unit of assignment.
--I am unaware that Quantrill captured an officer of the provost marshal's office or that he exchanged such a person for Mrs. McCoy's 1863 release. I'm not saying that it didn't happen, but just that I am unaware of it.
--I also drew a blank about the Confederate "Captain Burkholder." There were several Confederate recruiting officers captured this spring in the Clay County area, but I didn't see that name. Here again, that doesn't mean it didn't happen, just that I don't have details of it.
--Going to the Rock House Prairie of Platte County would be a logical place to get on a passenger train, because the Hannibal and St. Joseph Railroad tracks were near there.
--Mrs. McCoy indicated that her subsequent arrest was on the order of Union Major General William S. Rosecrans, which fits the chronology she suggests, since "Old Rosy" took command of the Dept. of the Missouri on January 30, 1864, and she stated the Union authorities took her from Liberty, Clay County, on 15 February.
--I don't have anything on the banishment of the 13 families, but it should be in one of the St. Louis papers of that time. Both the "Daily Missouri Democrat" and the "Daily Missouri Republican" are available on microfilm.
--Mrs. McCoy's "General Clayton" is Union Brigadier General Powell Clayton originally from Pennsylvania but a leader of Kansas troops who was stationed in Arkansas about the time she indicated.
--I would guess that "Mrs. Hendrix of Jackson County" is Rebecca Hendricks, the wife of guerrilla James A. Hendricks, who served in Quantrill's band from the start of that bunch. The 1860 census tells me that these Hendricks lived in Pink Hill Township of Jackson County.
--Mrs. McCoy probably knew the two Confederate officers she named since they were both Clay County area men, Colonel Boaz Roberts and Colonel Gideon Thompson.

Mrs. McCoy's Second Narrative.
--Mrs. McCoy's "when the Federals began to force men into the Reserved Missouri Militia" is undoubtedly the infamous Dept. of the Missouri General Orders Number 19 of July 1862 which ordered the enrolling of all able-bodied Missouri men in the just-then-forming Enrolled Missouri Militia. This order caused literally thousands of previously neutral Missouri men to either enroll as ordered, leave the state, or join the Confederate regular or irregular service.
--Other evidence tends to verify Mrs. McCoy's statement that the Union troops in Missouri were reluctant in most cases to explore the thickets for hiding guerrillas.
--The Rebels crossing the Missouri River had to hide their skiffs since the Union authorities in MO ordered all boats of all sizes controlled partly to prevent southern troops using them to cross that river. It hadn't occurred to me that Rebels would sink a skiff to hide it, and I guess it wouldn't occur to most of the Yanks either.
--Yes, Quantrill during 1862 and 1863 did assist Rebel recruiters and recruits to infiltrate past Union troops in his area. During 1863 Quantrill sent men familiar with the country on the north bank of the Missouri River to render this assistance.
--Regarding charging Mrs. McCoy with copying the key in wax and thus helping someone to escape from jail, a lady did exactly that during 1863 in Boonville, Cooper County, down the river.
--Louis Vandiver was executed in summer of 1864, if I have the right man.
--Both Captains Joe Hart and Fernando Scott were killed during 1863 in action. Fernando Scott was informal commander of the Clay County guerrillas such as Frank James and others in Clay County and Scott brought those men south of the Missouri River to join Quantrill in spring 1863. I would imagine Moses McCoy was one of those, but I can't prove it.
--See my remark about the accuracy of Mrs. McCoy's details of the 19 May Richfields fight in the above section.
--"Fletcher Taylor" is Charles Fletcher "Fletch" Taylor who led his own guerrilla group in 1864 and survived the war to serve as a successful owner of lead mines and a legislator.
--The "no quarter" rule of guerrilla fighting was first an order to Union soldiers in Missouri during early 1862 and quickly reciprocated by southern guerrillas and in effect throughout the war until May 1865 when the Union military cast the rule aside and granted amnesty to the guerrillas who surrendered. I think about the opening scenes of "The Outlaw Josey Wales" as I write this. This "no quarter" order was not always obeyed on either side, thank goodness.

I have no remarks regarding Mrs. McCoy's 22 May 1864 statement made a few days after her 17 May arrest. It speaks eloquently for itself.

I hope this helps,
