The reason I ask is that we know the number and sizes of gun carriages ordered by Gen Lovell at NO for the River Defense Service. The southern (forts) squadron appears to have been issued the proper guns and carriages, but the northern squadron sent up an initial element of three boats and only two carried ordnance. Gen. Lovell reported that because he was being tapped for guns for CSN vessels at NO that he didn't have enough guns. He anticipated sending most of the N. squadron boats up with gun rings aft and that the local Army command (Memphis or Ft. Pillow) would have to come up with the rest. They did so and in at least two cases supplied "barbette" carriages with the guns. With the evacuation of Ft. Pillow four of the heavy guns from the water battery were seconded to the northern squadron, presumably with their carriages. A survivor from the Lovell later wrote that they struggled to get the heavy gun aboard as a bow chaser. There is reason to believe that none of the four were mounted on gun rings as Lovell's recoiled and went overboard the first time they fired it! The guns and carriages that Gen. Lovell retained were intended to be mounted on gun circles, so it appears likely that were mounted as chasers at NO. One other possibility is that they went to the Louisiana Provisional Navy gunboats as both had bow and stern chasers like two of the RDS boats (Resolute and Bragg).
