What reading level is The Elevation of Sites for Seacoast Batteries book?
To quickly assess the difficulty of the text, read a short excerpt:
IV. To what extent will the field of fire of the battery be restricted by elevating its site ? These different elevations have reduced the angles of fall of arriving projectiles to 0, and have thus neutralized their searching power.
But what has been the effect upon the land guns, of thus elevating the battery site ?
These guns are mounted on carriages allowing the guns but 5 degrees depression ; hence they can not be used against vessels at ranges requiring them to be depressed more than 5 deg...rees.
A 10-inch rifle, firing over a crest 300 feet above the water, will have a dead zone whose radius is about 1, 000 yards; one firing over a crest whose elevation is 210 feet will have a dead zone of about 720 yards radius.
V. It has been shown that a gun mounted on either of three disappearing plans will not be directly hit when under direct fire of guns at ranges not exceeding 5, 000 yards; that the additional protection arising from the tabulated elevations of site is both unnecessary and slight for guns thus mounted, and is practically nothing for nondisappearing barbette guns ; and that moderate elevations of site result in dead zones, which should not be disregarded.
