That feelings kindred to those excited among the Covenanters were aroused among the colonists, is shown by the mottoes on "the Union flag with a red field," already spoken of as displayed on a liberty-pole in New York city in 1775. Those mottoes were, "No Popery," and "George Rex and the liberties of America." It was probably in reference to his being commander of the armies of the colonies, united in a solemn league and covenant in defence of civil and religious liberty, that General Washington adopted as his badge a light blue riband, which had already been identified with a similar league and covenant in Scotland. At a later day, on the adoption of an Union flag as the flag of the United Colonies, the color of the field of the union (derived, as was the blue border of the red flag of the Covenanters, from the banner of Scotland) being blue, this color became identified with that which gave nationality to the colonies, viz., their union, and on this account was adopted as the ground of the national uniform, and as the color for the chief or union, both in the arms of the United States and in their flag. That the prevailing colors of the uniforms of the army at that time corresponded to the colors of the flag, is a well-known fact. Thus the facings of the blue coats were red, the color of the plumes white, tipped with red, &c. The buff and blue, commonly regarded as the continental uniform, was that of the general officers, and not of the body of the troops. In the navy, the same was the case. The prevailing colors of the uniform of the officers of the navy were blue and red; those of the uniform of the marine officers, green and white: the colors of the flag of the United States, and of the flag of the floating batteries, before given, viz., white, with a green tree in the middle, &c. &c. That such considerations operate in the selection of colors for uniforms, is proved by the fact that the uniform of the United States corps of cadets, a corps instituted and kept up with a view to foster and preserve military knowledge in our country, instead of being of the national color, blue, is gray trimmed with black. This color for the uniform of that corps was chosen in 1815, out of compliment to the services of the brigade commanded by General Scott at Chippewa, &c., in the war of 1812-14. The embargo and the war having cut off the supply of blue cloths, the commissary-general of purchases was forced temporarily to supply that brigade with a substitute of gray, trimmed with black. As this, then, was the origin of the color of the uniform of the corps of cadets, may we not conclude that, for the reasons assigned, blue was adopted as our national color, out of compliment to the Union, with which, as we have shown, it was intimately connected. Having given the preceding account of our National Flag, we now add the names of those connected with its different phases. 1st. General Washington.
