John W.F. Clawgis was the Union surgeon in charge after the battle. He did not stay with the wounded on the field and instead went back to Lexington when the Union soldiers retreated. Shortly after he was accused of leaving the wounded Union soldiers on the battlefield on August 16, 1862. He was relieved of his duties as assistant surgeon on September 27, 1862 but due to a lack of qualified surgeons, was reinstated less than a month later. While we have not been able to find all of the pieces pertaining to this, below is what we were able to find and gives a brief outline of what transpired.
You can find his complete service records here.

Sir
Yours of the 19th inst is at hand with which I cheerfully comply. My reasons for leaving the wounded of 6th Regt as well as those of other Regts after the battle of Lone Jack were many, but principally the following.
After having applied to the QM for transportation for the wounded it being evident that for the time we should have to give up the battle ground, and our troops then being formed in column for retiring I saw that , owing to the large amount of wounded, to care for all of them at that place and under the circumstances, in anything like a humane manner would be utterly impossible, therefore I conversed with Maj Foster who had been in command but had fallen badley wounded, also with Capt B [Brawner] Co A 7th Reg Mo Vol who was then in command, as to what was best to do, I then called Doct Cundiff of Lieut Col Nugents Bat, counselled with him, he informed me that he was acquainted with the people & most of the Physicians in that vicinity. I therefore made arrangements with him to stay & take care of the wounded left behind by sending out & calling in all of the help that he could obtain for this relief; whilst I would accompany all who could be provided with transportation (45 in no.) to Lexington and make arrangements for returning immediately with hospl stores & transportation for the remainder which I did & that successfully.
Before leaving, however, I turned over all of my medicines most of my instruments and part of my hospt stores to Doct Cundiff (he having none) for the benefit of those left behind. In all that took place concerning this, I strove to do my duty as an officer and a Patriot, and if I have failed it is from no lack of intention to do right. What I have stated I can substantiate. If there is any further explanation desired please let me give it in person. Hoping that the above will be satisfactory, I remain your Obt Servt
