Your Palmyra Spectator article published Fri., Sept. 16, 1864, one week after the St. Louis and St. Jo press reports, which pinpoint the date as "on Wednesday." The Palmyra Spectator's reference of the occurrence was "Wednesday last."

The post-war accounts of the fight at Widow Turner's were all over the place, with Babe Hampton, a half-century after the fact, putting it early September. But those were all post-war recollective stabs in the dark, datewise. The contemporaneous Federal reports filed immediately after the fight are quite specific. It took place Sept. 23, 1864.

So, as Tom Todd, George Todd, and Caleb Perkins were ambushing the 3rd MSM wagon train at Goslin's Lane, the 9th MSM Cavalry was attacking Capt. Bissett and his squad at the Widow Turner's. Both fights occurred the afternoon of Sept. 23. A few hours later the disparate Confederate guerrilla bands, the Todds, Perkins, Thrailkill, et al came together 3/4 mile west of Cherry Grove School. That's also the Widow Turners farm. Early the next morning Bill Anderson arrives and finds out what happened to his close friend Bissett, at the site of his death, just a half day or so after the fact. The scalped body was probably laying right there in front of Bill Anderson, enhancing the effect and nature of Bissett's death resulting in Anderson's literal emotional breakdown, and precipitating the disastrous knee-jerk revenge attack on the 9th MSM Cavalry's base six miles away just mere hours after that.
