The correspondence of Jackson and Adair throws light upon the subject of this controversy, and reveals to us some of the causes of the errors and contentions of this affair. We have mentioned that Adair, in his eagerness to arm as many as possible of the Kentucky militia and place them in line for the main battle of the eighth, went into the city and plead with the Committee of Safety to loan him four hundred stand of arms, held in the city armory for the protection of New Orleans, for a few days. This urgent request was granted, and the arms privately moved out, hauled to the camp of the Kentuckians, and delivered there about nightfall of the seventh. Four hundred more of the Kentuckians were thus armed and moved up to the rear of the breastwork, ready for the battle next morning. Adair believed that he was acting in the line of his duty, and that Jackson would approve of his device for arming more of his idle men in camp. Busy as he was that day in New Orleans, and in equipping and marshaling the men of his command for battle, he was not made aware of the urgent need of reinforcements on the opposite bank of the river, nor did he know of the purpose of the commander-in-chief to arm these from the city armory. While Adair's device very much strengthened Jackson's line on the left bank, it unfortunately defeated Jackson's plan of sending four hundred more men to reinforce General Morgan on the right bank, and may in this way have largely contributed to the latter's defeat. When Jackson, late on the seventh, ordered a detail of five hundred of the Kentucky militia to be marched at once to New Orleans, there to be armed, to cross the river and report by daylight to General Morgan, he expected to use the arms from the city armory. There was no other supply.
