12 workmen of the line, and 8 of the artillery, are generally allotted to each gun.
If to the above proportion of materials, &c. for a battery of two guns, there be added for each additional gun, 30 fascines of 9 feet, and 10 of 18 feet, with 12 workmen, the quantity may easily be found for a battery of any number of pieces.
The workmen are generally thus disposed; one half the men of the line in the ditch at 3 feet asunder, who throw the earth upon the berm; one fourth upon the berm at 6 feet asunder, to throw the earth upon the epaulment, and the other quarter on the epaulment, to level the earth, and beat it down. The artillery men carry on the fascine work, and level the interior for the platforms. This number of workmen may complete a battery in 36 hours, allowing 216 cubic feet tn be dug and thrown up, by each man in the ditch in 24 hours.
Tools for the Construction of a Battery.
Intrenching—1½ times the number of workmen required; half to be pick axes, and half shovels or spades, according to the soil.
Mallets—3 per gun.
Earth Rammers—3 per gun.
Crosscut Saws—1 to every two guns.
Handbills or Hatchets—2 per gun.
This estimate of tools and workmen, does not include what may be required for making up the fascines, or preparing the other materials, but supposes them ready prepared. For these articles, see the words [Fascine], [Gabion], [Platform], &c. and for the construction of field magazines for batteries, see the word [Magazine].
