Jayne and Steve,
I have been following your progress discovering about the Warder's Church fight of 10 July 1864 in this forum, and assumed you were doing well with your hunt. However, your recent questions moved me to give you references for some detailed versions of this fight to assist your quest.
All versions of such skirmishes contain errors based on viewpoint of the writer, personal knowledge or lack of same by the recorder, incorrect information passed along to the writer, time of the writing after the event, among other reasons. Therefore, I find it useful to read several versions of the same event in the hope that at least a concensus of the various accounts may reveal some of the truth and some of the fiction. The ideal solution would be to find versions from both sides, but that is rare in Missouri guerrilla warfare. I have varied success with this method, and it has given me a skeptical attitude and a knowledge that everybody has some of the truth, and everybody has some of the not-so-true. I suppose the trick is to find enough versions to give you perspective, and enough experience to be able to discern what's what from what's not.
Well, enough of that. Here are several versions that you may find about this fight:

--"Official Records," series 1, vol. 41, part 1, pp. 65-67 (This Yankee version is about the most detailed of all of them, but you decide for yourself.);

--"Bushwhackers Killed in Church," (I think this is the correct headline.) "Lexington Weekly Union," 14 July 1864, (This appears to be the first press release of this fight. Sometimes the closest and first printed is the most accurate, but not always. Notice the word "Union" in the name of the paper, and is that a clue as to the editorial attitude of the Lex. paper, or is that just window-dressing to keep Union troops from raiding the paper's office some night? It's really hard to tell.)

--"Bushwhackers Killed in Church," newspaper on microfilm of "Kansas City Daily Journal of Commerce," 20 July 1864, taken from the Lexington newspaper article of 14 July. Was it copied word for word, or was some added or some parts dropped?);

--"Bushwhackers Killed," "Missouri Statesman," Columbia, Boone County, 12 August, probably taken from one or both of the above newspaper accounts (I can promise you that this paper has a definite Union bias, since the editor was a Union colonel. The question is: can his newspaper print the truth and in enough detail to assist you? Sometimes a later version of a story has a broader and more complete view. Did the Columbia paper have that this time?)

--E. J. Melton, "History of Cooper County, Missouri," Columbia, MO: E. W. Stephens Publ. Co., 1937, p.95 (There were several Cooper County histories dating from the 1880s all the way to this latter-day one. This is the only one that covers the Warder Church fight in detail or even mentions it. You have to wonder why, since Cooper County was about two counties removed from this skirmish. The 1860 Census shows a J. Wilhite lived in west-central Cooper County, but a Jefferson Wilhite also lived near Lone Jack in Jackson County. Perhaps they were related. Incidentally, there were a number of Wilhites on both sides of the Missouri River who were active in the Confederate army, some of them were also bushwhackers, and several of them were guerrilla leaders, too. The 1937 Cooper County history writer was actually writing to extol the virtues of the great judge of the Federal Court of the Western Missouri District, as appointed by President Grover Cleveland, who was John F. Phillips, formerly commander of the 7th Cavalry Missouri State Militia. Now, what unit were those Yanks from that fought at Warder's Church? Do you see the connection? Personally, I don't, but we can see that Mr. Melton's book certainly thought a lot of the 7th Cav MSM commander. But why print this in a Cooper County history? Perhaps the Jeff or Jefferson Wilhite that died 10 July at Warder's Church WAS the one from Cooper County, and the author wanted to make a statement, but I have my doubts. Perhaps we will never know, but it does give us a detailed story of the fight, although we are warned this version will not be kindly inclined to the guerrilla side of the story.)

--Joanne Chiles Eakin and Donald R. Hale, "Branded As Rebels," publ. Independence, MO: by Wee Print, 1993, p. 467 (If you know anything about Joanne Eakin and Donald Hale, you know they have worked hard for years to give voice to the guerrilla side of the war in Missouri, and the title of this book should also be a clue to that.
Incidentally, Eakin and Hale on page 467 tell us that Jeff or Jefferson Wilhite is bured in "Tom Harper" or "Hopper Cemetery" in section one, township 49, range 23, which location you probably already know. They also say that "Albert (or Alvis) Estes" is buried there with Wilhite, and that four other guerrillas were killed there that day, although they don't name them, nor state where those four are buried. It is possible that these guerrillas' kinfolk gathered their remains and took them someplace else for burial, perhaps in a family plot? If you also look at the entry for Green B. Austin on pages 11-12 and for John Prock on page 359 in this same book you will see that both men were also on the guerrilla side of the Warder Church Fight, and that Eakin and Hale reveal that both Prock and Austin not only survived this fight, but lived on into the postwar period, and both died in the 20th century.

There are other versions of this fight in other sources, but these I listed above are pretty good.
I hope this helps.
