In accordance with the Continental Marine Act of 1775, the Congress decreed

[madshutterbug]

That two battalions of Marines be raised consisting of one Colonel, two lieutenant-colonels, two majors and other officers, as usual in other regiments; that they consist of an equal number of privates as with other battalions, that particular care be taken that no persons be appointed to offices, or enlisted into said battalions, but such as are good seamen, or so acquainted with maritime affairs as to be able to serve for and during the present war with Great Britain and the Colonies; unless dismissed by Congress; that they be distinguished by the names of the First and Second Battalions of Marines.

Semper Fi!
