Defensive Works and Forces on the West Bank, Opposite Jackson's Camp.
General Morgan, commanding the Louisiana militia, was in position on Raquet's old canal site, next to the river. Major Latour, chief of the engineer corps, had been instructed by General Jackson, a week or two before the battle, to proceed across the river and to select on that side a suitable line for defensive works for General Morgan, in case the enemy should attempt a flanking movement on the right bank. Of this mission, Major Latour writes:
Agreeable to orders, I waited on General Morgan, and in the presence of Commodore Patterson communicated to him my orders, and told him I was at his disposal. The General seemed not to come to a conclusion, but inclined to make choice of Raquet's line. He then desired that I inspect the different situations myself, and make my report to him. My orders were to assist him, and my opinion was subordinate to his.
I chose for the intended line of defense an intermediate position, nearly at equal distances from Raquet's and Jourdan's canal, where the wood inclines to the river, leaving a space of only about nine hundred yards between the swampy wood and the river. Works occupying this space could not well be turned, without a siege and assault in heavy force by the enemy. I made a rough draft of the intended line, and immediately the overseer set his negroes to execute the work. Returning to the left bank, I made my report to the Commander-in-chief, who approved the disposition made. One thousand men could have guarded a breastwork line here, and half that number would have been sufficient had pieces of cannon been mounted in the intended outworks. That line, defended by the eight hundred troops and the artillery of General Morgan's command, on the 8th, could have defied three or four times the number of British who crossed over to the right bank that day. But these dispositions had been changed by General Morgan, and the negroes ordered to work on the Raquet line.
Major Latour had selected for General Jackson his line of defense on the left bank of the river, and had directed the construction of the breastwork and redoubts to the entire satisfaction of the General. He objected to the Raquet line favored by General Morgan, as wholly unsuited for defense. The space here from the river to the wood swamp was two thousand yards, or considerably over one mile, a much longer line than Jackson's on the other side. To be effective against an attacking force, the entrenchment and outworks must be extended to cover the entire space. It would require then more than double the number of troops and of pieces of artillery for defense than the situation selected by Latour.
In determining on this change of the line of defense, contrary to the judgment and warning of the chief of the engineer corps, General Morgan seems to have been influenced by one consideration paramount to all others. He was in daily council with Commodore Patterson, and was assured of the powerful aid of his battery on the right bank, which had done such execution in the ranks of the British across the river. Should the enemy attack General Morgan's position at Raquet's line, the Commodore could turn his twelve pieces of cannon in their embrasures, sweep the field, and drive back any reasonable force in range. With this support of his artillery, the few hundred militia of Morgan's command could more successfully repulse an attack at Raquet's line than at the line selected by Latour farther away. This change in the situation and plan of defense is characterized by Latour and other authorities as an unmilitary proceeding, as it abandoned the idea of a fortified line behind which a successful defense could have been made probable, if not certain, for an almost open field subject to the flanking movement of veteran troops against raw militia, with no auxiliary support except a park of artillery with guns turned another way, and of most doubtful use in case of need. General Morgan must not share alone the criticism which has been so freely made of his disposition of forces and changes of strategic plans which resulted in sensational disaster to his command. Commodore Patterson, experienced in military affairs as well as naval, advised with him, and must have approved. This change of line, made some days before the eighth, must have been known, and on the representations of Morgan and Patterson, approved by General Jackson. It is not conceivable that so important a change of plans would have been made by a subordinate officer, affecting seriously the safety of New Orleans, without the consent of the commander-in-chief. The latter seemed always to have held in very high personal esteem these two officers, and to have had confidence in their abilities as commanders.
As mentioned above, the dispositions made for a line of defense by Major Latour were changed by General Morgan, and the negroes set to work on Raquet's line. A breastwork fortification was thrown up by the seventh of January, extending but two hundred yards from the river bank out on the site of the old canal. From this terminus across the plantation land to the wooded swamp was an open plain, with scarce an obstruction to the deploy of troops or the sweep of artillery. The old canal had long been in disuse, and the ditch was filled nearly full with the washings and deposits of years. Behind this two hundred yards of entrenchment General Morgan massed all the Louisiana troops of his command and planted his artillery, three pieces in all. From the end of the breastwork on the right, one mile or eighteen hundred yards to the swamp, there were no defensive works from behind which to repulse the assault of an enemy, nor any means of resistance in sight to an attack, other than the guns in battery of Commodore Patterson, of more than doubtful use, and the yet very doubtful contingent of reinforcements sufficient from General Jackson's limited supply of men and arms.
On the seventh, the forces of Morgan's immediate command were the First Louisiana Militia on the left, next to the river; on the right of these, the Second Louisiana; and on the right of the latter, the drafted Louisiana militia, in all about five hundred men, who occupied the fortified line of two hundred yards. It was not until late this day that General Jackson seemed to fully awaken to the impending dangers of this formidable flanking movement across the river. He at once gave orders that five hundred of the unarmed Kentucky militia in camp should be marched up the river to New Orleans and receive certain arms in store there; then cross the river, and march down five miles on the west bank and reinforce General Morgan's command by, or before, daylight next morning. It was late afternoon when they started on this tramp of ten miles, through mud and mire ankle deep. Arriving at New Orleans, it was found that four hundred stand of arms which were expected to be obtained from the city armory had been loaned to General Adair, and sent to him at the Kentucky camp for other use. From other sources some miscellaneous old guns were obtained to equip less than two hundred of the detailed Kentuckians, who crossed the river, began their weary night march, and reported to General Morgan before daylight of the eighth, ready for duty, though they had not slept for twenty-four hours, nor eaten anything since noon of the previous day. Their arms, a mongrel lot, were many of them unfit for combat; old muskets and hunting-pieces, some without flints, and others too small-bored for the cartridges.
