 the armament. 



Montg6ry's description, published in 1822, was 

 taken from his report to the Minister of Marine and 

 Colonies. It noted the battery was made oi two 

 hulls separated h\ a channel, or "race." l.V, feel 

 wide, running the full length of the vessel. The two 

 hulls were joined by a deck just above the waterline, 

 as well as by an upper deck, and also connected at 

 their keels In means of 12 oak beams each 1 foot 

 square. The vessel was 152 feet long, 57 feet beam, 

 and 20 feet deep. Sides were I feel 10 inches thick, 

 and the ends of the hull were rounded and alike. 

 There were two i udders at each end. one on each hull. 

 alongside the race. The eight paddle blades, each 

 II 1 feet by 3 feet, turned in either direction by 

 stopping the engine piston at hall-stroke and revers- 

 ing the flow of steam. Rigged with two lateen sails 



and two jibs, the ship sailed either end first. I he 

 engine of 120 hp was in one hull and two boilers 

 were in the other. Other sources, Marestier, and

 eter cylinder, 5-fool stroke, direct-connected to 



the paddle wheel, which was tinned at 18 ipm. I he 



boilers wen- 8 \ 22 feet with the fireboxes in inside

about hall the length of the boiler from the fire doors. 



I WO fire tubes, each about 3 feet in diameter, returned

 the lirebox was completely surrounded b\ water. 

 The boiler pressure oi about 6 psi w.is not maintained, 

 varying somewhat with eai h stroke ol the engine.

 cocks. I he -.I ha \ valve was controlled b) a counter- 

 balanced lever. A jet of salt water was injected into 

 the exhaust trunk to form a vacuum In condensation. 

 An aii pump transferred condensate and sea water 

 into a tank from which it passed overboard. < >nlv 



about a tenth ol this w.itei was returned to the boilers. 



Montger) stated also that only the lowei oi gun 

 deck was to be armed. No bulwarks were on the 

 spar deck, only iron stanchions to which wen fa 

 a breastwork oi we( cotton bales when the 

 Batterj was in action. 



The Battel v was designed to carr) 30 guns (32-pdr.), 

 with 3 nuns in each end and 12 on each side, but no 

 guns in the wake ol paddle wheel and machinery. 



Hatches to give air to the stokehold were located 

 amidships. The Batter) was to have been supple- 

 mented at the ends of each hull by a Columbiad 

 "submarine gun" I 100-pdr.), Fulton's invention, but 

 these wen- not fitted. Provision was to be made in 

 the fireboxes foi heating shot, and a force pump with a 

 i \ lindei 1 1 ini lies in diametei was employed to throw 

 a stream of cold water, about 60 80 gallons per 

 minute, foi a distance ol about two hundred feet. 

 This could be done onlv when the paddle wheel was 

 not in operation. 1 In- paddle wheel was housed.

 deck, over the race, was used in part for stati ro 



of which the bulkheads were permanent. ILini- 



mocks foi the < i mipli in iOO en were to be slung 



on the rest of the gun deck. The ship drew 111 feel 

 ■\ inches, with the port sills about .V. feet above the 

 loadline. Burning wood, the vessel could carry about 

 1 days' supplv ol fuel; burning coal, she carried 12 



davs' supply. 



\Ioiit'_iei v said that the vessel would be vulnerable 

 to bombshells and hot shot, and that furthermore she 

 could be boarded. The displacement of the ship, at 



service draft, was 1,450 tons. .1 figure Montuerv
