ENSIGN, or _ensign-bearer_, is an officer who carries the colors being the lowest commissioned officer in a company of foot, subordinate to the captain and lieutenant. The word ensign is very ancient, being used both by the Greeks and Romans, and amongst both foot and horse. Ensigns belonging to the foot, were either the common ones of the whole legion, or the particular ones of the manipuli. The common ensign of the whole legion was an eagle of gold or silver, fixed on the top of a spear, holding a thunderbolt in his talons as ready to deliver it. That this was not peculiar to the Romans, is evident from the testimony of Xenophon, who informs us, that the royal ensign of Cyrus was a golden eagle spread over a shield, and fastened on a spear, and that the same was still used by the Persian kings. In the rustic age of Rome, the ensigns were nothing more than a wisp of hay carried on a pole, as the word _manipulus_ properly signifies. The ensign of the cavalry was a dragon; but there were some of cloth, somewhat like our colors, distended on a staff; on which the names of the emperors were generally depicted. The religious care the soldiers took of their ensigns, was extraordinary: they worshipped them, swore by them (as at present several European powers do) and incurred certain death if they lost them. The Turks and Tartars make use of horses tails for their ensigns, whose number distinguishes the rank of their commanders; for the Sultan has 7, and the Grand Vizier only 3, &c. ENTERPRIZE, in military history, an undertaking attended with some hazard and danger. ENTERPRISER, an officer who undertakes or engages in any important and hazardous design.
