Okay, it seems things were going along fine until I came to the part that you said "To repeat, the Conscript law "killed" existing organizations; not the ability of the state to form militia on another basis of enrollment". All existing militia organizations were not "killed" at that time. On that vein, I will include examples of existing militia still in use after the dates you specify.

NATCHITOCHES [LA] UNION, June 12, 1862, p. 1, c. 2

Parish of Lafayette, May 30th 1862.

Dear Friend Dupleix,

At your request, herewith I send you some details about our last troubles here.

You are already aware of the great revolt we had here, so it is needless for me to repeat it again. Suffice it to say that we were for a while in great trouble, and I may say, in great danger. The militia of Vermillion refused to go to war and were prepared to attack the village and kill us all, if possible. Luckily, the revolt was stopped before it got too late, and we are now almost quiet. Every now and then, we have rumors of Yankees coming in our neighborhood, but they never venture this far. Yesterday, they took prisoner, three splendid looking yankee officers, and this morning, they passed through Vermilionville on their way to Opelousas Jail. I went to see them, of course, as did every body else, and found them to be fine looking men, dressed in their uniform, with more gold lace about them than was necessary. They looked not like prisoners, for they were gay and smiling. It was the Capt. of a St. Martinville Company, named Fuller, who took them prisoners. It seems that Gen. Butler had taken possession of our Rail Road which runs from New Orleans to Berwick's Bay, and they were in a habit of putting officers on it, so as to see that every thing went right. Well, yesterday Capt. Fuller stopped the cars, took the Yankees, destroyed all the bridges, and run back with the cars. It was quite an undertaking, and I know, will get us in considerable trouble, for Gen. Butler will not remain inactive, and see his officers in jail. But let him come, we are prepared to receive him. We have now sent out about eight hundred men, they are encamped near New Iberia, and we are expecting to day a Regiment from Texas. Nearly every day there are companies passing from different Parishes around. I think shortly, we will be amply protected. The good Citizens, here, are determined to die, rather [than] to give up.

If something new, I will let you know it.

My 2nd Source is from the "South's Defender" blog run by my friend, Mike Jones. It contained this example on militia that was not completely disbanded past the date you mention.

"Upon the invasion of Louisiana and the fall of New Orleans, the Invincibles were disbanded and told to report to Camp Moore in Tangipahoa, about 80 miles to the north. Apparently the company did not remain intact, as some of the men were assigned to or joined other units such as Miles Louisiana Legion, the 27th and 28th Louisiana Infantry regiments, and the 8th Louisiana Infantry. However others appeared to have returned home, or at least no further records of their military service have been found.

Captain Johnson remained in command of the Calcasieu Militia and when a northern revolutionary gunboat raided his hometown of Lake Charles in October, 1862, he again mustered the remaining militiamen to fight the raiders. However when the militia was about to fire on the ship the northerners had stolen, they discovered the raiders had taken 10 hostages from the town and tied them up around the helmsman, thus using them as human shields. Johnson's men held their fire in spite of being fired upon the the raiders' boat howitzer. The raiders completed their rampage of theft and terror and went back out to the Gulf of Mexico."

Let us also not forget the Terrebonne Militia Regiment that was activated in June, 1862 as an existing militia unit to assist in the repulsing of the Yankees at Georgia Plantation near Labadieville on October 27, 1862.

I also found this interesting.

In General Order No. 6, from the Headquarters of the Bureau of Conscription, for the Department Trans-Mississippi issued at Shreveport, LA on August 4, 1863, Section 1 says, "An Act to repeal certain clauses of an act entitled an act to exempt certain Persons from Military Service, etc., approved 11th October, 1862. Part 4 of Section 1 states, "In addition to the State officers exempted by the act of October 11, 1862, there shall be also exempted State officers whom the Governor of any state ay claim to have exempted for the due administration of the government and laws thereof, but this exemption shall not continue in any State after the adjurnment of the next regular session of its legislature, unless such legislature shall, by law, exempt them from military duty in the provisional army of the Confederate States."

I interpret that to mean that if the state had a law keeping its militia that the Confederates could not mess with them as they were "exempted for the due administration of the government" which would include the Adjutant General's office. This last statement of mine is further evidenced by the wording in General Order No. 57 issued from the Headquarters of the Trans-Mississippi in Shreveport on July 23, 1864, Part II, which directs, "Assessors and Collectors of Confederate taxes, Officers of the Confederate Treasury, and employees of the Nitre and Mining Bureau, and the Adjutant General's Department will not be interfered with..."

As to the "small units" you refer to that I mentioned from Art's book, if you look closely, they were formed by mounting militia infantry units already in State service.
