The Gun
sights and laying - gunnery


During the smooth-bore era virtually all fire was direct. On the very rare occasions indirect fire was attempted it invariably involved siege operations in which ample time was available. Until the introduction of the dial sight in the last decade of the 19th century, indirect fire was not practicable; it involved a time-consuming lining up of aiming posts, was possible only in easy rolling country, and was generally suited to howitzers only.
