Note 93 — VII THE INVESTMENT OF BOSTON

This system of night attack has been developed and tested by actual trial, and is such as is now laid down for battle practice in the tactics of most navies. “The ... squadron will enter ..., and will maneuver at range of about 9,000 yards from Fort ..., firing heavily, to induce the defense to expend as much ammunition as possible.”—Extract from actual orders in author’s possession, given to a squadron of battleships and cruisers for night attack. It will be noted that this distance is less than one-half the range of the 12-inch rifled mortars in a harbor defense battery.
