Thanks for the informtion. Muriel H. Wright, long-time editor of the Chronicle of Oklahoma, had told me that the men died of cholera. I'm glad to have this clarification.
By the way, as an up-date on the Middle Boggy re-enactment: The board of the Oklahoma Historical Society voted last year to "standardize" the three re-enactments which the OHS sponsors (at least on a trial basis).
The three rotate between Cabin Creek (east of US 69 in Mayes County) , Honey Springs (at US 69 in McIntosh County) , and Middle Boggy (west of US 69 in Atoka County) .
The reenactments are the weekend containing the last Saturday of September, with a "school day" that Friday. (That's usually the last weekend of Sept., but might from time to time be Saturday, 9/30 - Sunday, 10/1.)
The primary reason for this schedule is to have the event during the school year so children can have a learning opportunity. A principal secondary reason is that 109 degrees on a Saturday in July is just not friendly to old people, young people, volunteers, or men in wool uniforms!!!
