That's a tough one. Herron definitely sent some or all of the captured telegrams to St. Louis along with the captured Confederate flag from the Crawford County courthouse in Van Buren. He was a Curtis protege and did everything he could to show his appreciation to "Uncle Sam."

I assume the telegrams reached Curtis because thereafter he occasionally made cryptic comments such as (I am roughly paraphrasing here) "we know just how serious the logistical situation is in Arkansas." What physically happened to the telegrams after they arrived in St. Louis I don't know. I didn't find them when I plowed through Curtis' headquarters papers in the National Archives years ago, but those papers are so voluminous I barely made a dent. The U.S. Army generated a truly impressive pile of paperwork, even in the trans-Mississippi.

The Confederates made multiple copies of all their military correspondence so the captured telegrams almost certainly are in the Alexander Papers. The problem, of course, is that we have no way of knowing which ones they are.
