As early as the 2d of March Porter assembled at the mouth of the Red River a great fleet of nineteen ironclads, including fifteen of the heavier class and four of the lighter. The fleet carried 162 guns, of which 62 were of the higher calibres, from 80-pounder rifles up to 11-inch Dahlgrens, and the combined weight of projectiles was but little less than five tons.
The plan was to bore out a cast iron gun and then to insert a wrought iron rifled barrel consisting of two tubes of coiled iron one inside the other. By the firing of a proof charge the wrought iron barrel was tightened inside the cast iron casing. By this means we obtained a converted gun at one-third of the cost of a new gun, and saved L140 on a 64-pounder and L210 on an 80-pounder.
