Colonel

Continental Army officer, aide-de-camp to Washington, son of Henry Laurens; 1754—82.
German colonel, mortally wounded during the Battle of Trenton; 1726—76.

In the fall of 1775 Congress chose brown as the original color for the national uniform. In October 1778, however, France sent uniforms with a predominance of blue coats (although there were also brown), and so on 2 October 1779 Congress switched to blue as the official color.
