Jim,

According to Dyer's Compendium, Cos. "A," "D," "F" and "G" of the 32nd Iowa were detached from the Regiment and moved to Cape Girardeau, Mo., November 25-28, 1862. Those companies were attached to District of Southeast Missouri until July, 1863. There service is listed as "Garrison duty at Cape Girardeau, Mo., till March 14, 1863. Moved to Bloomfield March 14 and return to Cape Girardeau April 21. Action at Cape Girardeau April 28. Pursuit of Marmaduke to Castor April 28-May 5. At Cape Girardeau till July."

There is one paragraph in Scott's book that directly relates to an action near Cape Girardeau on April 24, 1863 (that's the date in Scott's book). I quote it here in it's entirety:
"The detachment of 32nd Iowa did good service. Some of them who had been on the advanced picket line fell back to a ravine between the contending forces, where, with no opportunity of firing a gun the shot and shell passed both ways over their heads. It can certainly be said of these that they were "under fire." The rebel gunners were quite careless, and some missiles fell among our boys, but none were struck. The body of the detachment held an important position that was not assailed, and happily no Iowa blood was shed in this affair."

This probably wasn't what you were hoping for, but that's what the book has. Scott wasn't there, and got his information from a Sergeant Boyd, who was with the detachment and kept a diary, which Scott frequently quotes from in his book, even for times when Boyd and Scott were involved in the same actions.

There is some more details about the detachment's involvement in that campaign, and if you'd like copies of the relevant pages, e-mail me direct with your mailing address and I'll put them in the mail to you. It's not a whole lot, but if you want it, it's not a problem.
