This is certainly one of the better Stooges vehicles I've watched so far, arguably lifted by its Civil War setting: the boys are Union secret agents(!) sent on a mission behind enemy lines. While the level of invention isn't up to that seen in Buster Keaton's similar THE GENERAL (1927) and it would be unrealistic to expect it to be it's still a reasonably sustained comical piece.
The trio's typical slapfest routine is, together with the aid of impersonation and mimicry, utilized as a means of confusing the Confederates and retrieve the information they were assigned to procure (which is summarily destroyed by Curley when he rolls the paper used by Moe to write it all down to make a cigarette!). The ending sees The Stooges fired out of an enemy cannon and landing on the superior officers from their own lines!
