The following quotes are taken from Series I, Volume VI of the Official Records.

The call to which Dupiere responded was the last of several issued by General Lovell.

page 561, sworn testimony of Major General Lovell:

In February I was ordered by the War Department to send 5,000 men also to Columbus, which took away all my available force in New Orleans, leaving me without a single armed regiment of Confederate troops in the city. Every vessel of war ready for service in the river was also ordered up to the same point, and the department left without ships or men, except the garrisons of the works on the exterior line. On February 25 I made requisitions on the governor of Louisiana for 10,000 militia for the defense of the city, but the adjutant-general of the State reported that, in November, 1861, he had only about 6,000 armed militia available, and that since that time 3,000 of the best armed of these troops had been sent to reinforce the army in Tennessee upon the requisition of General Beauregard. This gave me for the defense of New Orleans less than 3,000 militia, of which 1,200 had muskets, and the remainder very indifferent shot-guns. These troops were commanded by their own State officers, and a part of them, when ordered to the support of Fort Jackson, mutinied and refused to go, and had to be forced on board the transports by other regiments. I reported to the War Department the manner in which my district had been stripped of men, guns, and ships, and objected thereto.

HEADQUARTERS DEPARTMENT No. 1, New Orleans, La., February 25, 1862.
His Excellency Gov. THOMAS O. MOORE:

SIR: I have the honor to make requisition upon you for volunteers and militia to the number of 10,000 men, to be placed in camp and held ready for defense at short notice.

Very respectfully, your obedient servant,
M. LOVELL Major-General, Cornmanding.

page 564, sworn testimony of Major General Lovell:

I issued no ammunition to the militia at the camp near the interior line because they were utterly useless against ships; no land attack was anticipated, and, above all, they had, in some regiments, manifested such an insubordinate disposition, that I felt unwilling to put ammunition in their hands. I had, however, 600,000 rounds of shot-gun cartridges made up for their use, and put in the arsenal ready for use when the proper time should arrive.

page 568, sworn testimony of S L James, volunteer aide to General Lovell:

During that evening General Lovell, to gratify the people, ordered me to call for 1,000 men to man these boats for a band-to-hand fight with the enemy’s vessels, although General Lovell said it was impracticable. The citizens promised to have the men ready the next morning at 9 o’clock. I was authorized to take the boats that were left and make such arrangements as I thought necessary to carry out the plan. I published this order (with an appeal of my own to the people) in all the city papers. In the mean while I sent down cotton bales to protect the boats, and molasses barrels to put in their hulls to keep them afloat in the event they were penetrated by shot. I called upon General Lewis and other militia officers to assist me in carrying out this scheme which they failed to do, and I only received in response to the call 140 men, without arms, under Captain Dupiere. Hearing that the enemy’s vessels were at Camp Chalmette, about 5 miles below the city, I sent an officer to the landing, who ascertained that the citizens had burned a number of the boats and the owners of the others had gone off with them. I then ordered these 140 men to proceed to the Jackson Railroad depot to go to Camp Moore, and I then went to Camp Moore.

Your post references a requisition made made by the Confederate government. At different times President Davis called upon state governors to furnish troops in certain numbers. In strict business terms a purchase transaction is implied, but not always. This is one of several letters Secretary of War Benjamin addressed to each governor for a requisition of troops. From the Official Records, Series IV, Vol I, pages 902-903:

CONFEDERATE STATES OF AMERICA, WAR DEPARTMENT, Richmond, Va., February 2, 1862.
JOHN GILL SHORTER, Governor of Alabama, Montgomery, Ala.:

SIR: In compliance with the recent act of Congress, entitled "An act to authorize the President to call upon the several States for troops to serve for three years or during the war," I am instructed by the President to call upon the Governors of the several States to fill up the quota of troops enlisted for the war to an amount equal to 6 per cent of the total white population. According to this basis the number of troops still required from the State of Alabama would be 15,351; but the State has furnished, in addition to the troops for the war, 9,970 men for twelve months, and it is deemed safe to rely upon the re-enlistment of half that number under the act of Congress providing bounty and furlough for re-enlisted men. I have, therefore, the honor to request Your Excellency to furnish from the State of Alabama twelve regiments of troops for the war, being the number that will be required, as nearly as can now be estimated, to supply the quota of your State. These troops will be mustered into service at convenient camps of instruction, which you are respectfully requested to select, and will there be clothed, supplied, and armed at the expense of the Confederate States. Each soldier will receive a bounty of $50 when the regiment or company is mustered into service, and will be allowed transportation from his home to the place of rendezvous. It is earnestly desired that the troops now called for be ready to take the field by March 15 at furthest. If subsequent experience shall show that the number of twelve-months volunteers who re-enlist varies materially from the estimate above made, this requisition will be modified accordingly.

I am, very respectfully, your obedient servant,
J. P. BENJAMIN, Secretary of War

The requisition made to Governor Moore of Louisiana was for 5-1/2 regiments, 9,734 troops required, 10,634 12-months men to be furnished in addition to those for the war.

Series IV contains numerous references to 'requisition' in reference to troops, arms, equipment, supplies and funds.

'Levy' is another term often seen in references to a call of troops.

page 595, sworn testimony of Maj W H Deveraux. Note that some of these volunteers have no arms.

Question. What was the number and composition of the troops in the city at the time of the evacuation and how were they armed?
Answer. There were two brigades of State troops, under Generals Tracy and Buisson, in New Orleans at the time of its evacuation. These numbered in all, perhaps, 8,000 men; were new levies, chiefly composed of the men of the families resident in and about the city. They were indifferently armed, shot-guns being I believe the prevailing weapon. Two-thirds of them belonged to the French class of the population. Included in the above estimate was a battalion of some 400 men, Orleans Guards, which was well armed and equipped. There were, besides, the Confederate Regiment State Troops, about 700 strong, well armed and equipped, and the Pinckney Battalion (now Eighth Louisiana Battalion), heavy artillery, 500 unarmed men, newly enlisted, occupying the works on the river above and below the city; also the Thomas Battalion Confederate Troops, numbering about 350 men, also unarmed.
