You are correct - examples cited from the O.R. concerned requisitions by the Confederate military upon the State of Louisiana. Please note that all requisitions were made by chain of command and directed to the Governor of Louisiana. It was his responsibility to call individual units into service by means of state militia chain of command. Confederate commanders did not make requisitions directly upon militia officers.

The Mayor of New Orleans had no involvement in militia activities or organization. The only state civil official who carried any authority under the law was the Governor as commander-in-chief.

We really must understand the difference between a qualified organization under the law and a call upon a qualified organization. See Section 29 of the law concerning the governor's ability to call an organization into service. Any militia command called for a period longer than twelve hours had to be provided with proper quarters or tents and provisions. Normal militia duties - drill and reviews -- could be completed in far less time. As the law states, under a call for service the governor designated a rendezvous for the command being called and had state quartermasters and commissaries deliver supplies and provisions to that point.

Section 30 concerns the 90-day limit of service. Contrast that with militia organizations, which had no term limits. An exception is made for emergencies requiring six months, but I don't know of a case in which actually happened. Even militia units such as the Crescent Regiment and the Orleans Guard Battalion that fought with Johnston's army at Shiloh disbanded when their ninety-day term ended.

Sections 32 and 33 concern normally expected militia duties and exemptions available to the militia while going to assembly and returning home. The Federal census was frequently taken within local militia beat lines. Since each militia company was based on a limited area, any resident could walk or ride to drill and return home in far less than twelve hours. Section 31 allows a local militia officer to call his command out during an emergency. These would be understood as cases in which civil law enforcement officers were not equal to the task of maintaining law and order in a militia beat.

Here's the law again --

Pam, since you understand the distinction between qualification to serve and an actual call to serve, maybe you can do a better job of explaining why the two are different. You've already mentioned that pay is one distinction. That's also true of militia called into service: they got paid for leaving home. What are some others?
