Note 96 — VII THE INVESTMENT OF BOSTON
Reading edition
Usually the firing zones are: first, 6,000 yards to the extreme range of biggest guns; second or intermediate, 3,000 yards to 6,000 yards; third (mine field zone), 3,000 yards. The order of fire is worked out absolutely for every condition that is possible. The movements of attacking ships, and their combinations, although very numerous, can be predicated with some accuracy beforehand.
