JACKSON ENTRENCHES AT RODRIQUE'S OLD CANAL SITE. As mentioned, Jackson occupied the line of Rodrique's Canal, two miles above the British camp at Villere's, and five miles below the city. The space from the river here back to the swamp was but seventeen hundred yards, making it an admirable line for defense. Early on the twenty-fourth every available man was put to work throwing up a breastwork on the upper side of the canal, while pieces of artillery were planted at commanding points for immediate emergency. Negroes from the adjacent plantations were called in to expedite the work of building the entrenchment and suitable redoubts, as had been done at other works of fortification and defense. On the twenty-fifth, General Morgan was ordered to abandon the post at English Turn and to move his command of Louisiana militia to a position on the right bank of the river, at Flood's plantation, opposite Jackson's camp. THE SHIP CAROLINA BURNED WITH HOT SHOT--ARTILLERY DUEL ON THE TWENTY-EIGHTH. The enemy determined to destroy the ship Carolina, as she lay out in the river, from whose deadly broadsides by day and by night they had been so terribly harassed since the opening of the night battle of the twenty-third. Having brought up their artillery from their landing-place, they erected a battery commanding that part of the river, with a furnace for heating shot. On the twenty-seventh, they opened fire in range, and in fifteen minutes the schooner was set on fire by the red-hot missiles and burned to the water's edge. The fire of the battery was next directed against the Louisiana, a larger war-vessel, the preservation of which was of great importance. Lieutenant Thompson, in command, with the combined efforts of one hundred men of his crew, succeeded under fire of the battery in towing her beyond the range of the guns of the enemy.
