ADMIRAL also denotes the commander in chief of a single fleet or squadron; or, in general, any flag-officer whatever. In the British navy, besides the admiral who commands in chief, there are the vice-admiral, who commands the second squadron; and the rear-admiral, who commands the third. The admiral carries his flag at the main-top-mast-head; the vice-admiral at the fore-top-mast-head; and the rear-admiral at the mizen-top-mast-head. See FLAG.
