J.T. Edson was one of my favorite authors for obvious reasons. I have about 20 of his books including his now rare book titled "The Ladies of J.T. Edson" which features quite a few women fights. One of my favorities was "Bunduki". Unlike the Westerns that Edson was known for, "Bunduki" has a "Tarzan" Jungle theme and featured several good female fights. The book was actually authorized by the son of Edgar Rice Burroughs. The lead character is Bunduki, Tarzan's adopted son and the female lead is "Dawn", an adoptive cousine. The book was published in 1975 and was Book 1 of a 5 book series.The 2nd book was "Bunduki and Dawn" (Jan 1976) and the 3rd book was "Sacrifice for thte Quagga God" (Oct 1976). After the third book was published, the Burroughs Estate withdrew their authorization to use the Tarzan name; so, the 4th book - "Fearless Master of the Junge" (Jun 1980) and the 5th book - "Amazons of Zillikian" do not mention the family connection to Tarzan and Jane. This series is almost impossible to find although you may find them in England. I purchased my copy of Bunduki on a trip to England. I do not know if there are any fighting women in the other 4 books of the series but I would say there is a high probability that there is.
For what it is worth, I believe that "Quiet Town" has the best fight of the Western series.
I believe that JT Edson is still alive; at least, he was about two years ago.
