Halberd

This is an element from a ceremonial staff weapon that
was used to indicate rank or to escort important people.
The halberd originated as a staff weapon of the foot
soldier, combining the advantages of the spear and the
axe. By the early 17th century, halberds were carried by
sergeants as a sign of rank and to signal commands to
their companies. The 1612 martial laws for the Jamestown
colony required the sergeants to carry halberds for
garrison duty but to abandon them in favor of firearms in
the field.
Halberdiers were employed at Jamestown in 1610 as
special guards to Governor De La Warre, who embraced the
pomp and ceremony of this office in his efforts to
rediscipline and revitalize the flagging colony. The iron
halberd head in this image was found in the ca. 1610
fill of Structure 165's cellar and may be one of the
weapons of De La Warre's halberdiers.
