Famous quotes containing the word blue:
“So here they are, the dog-faced soldiers, the regulars, the fifty-cents-a-day professionals riding the outposts of the nation, from Fort Reno to Fort Apache, from Sheridan to Stark. They were all the same. Men in dirty-shirt blue and only a cold page in the history books to mark their passing. But wherever they rode and whatever they fought for, that place became the United States.”
—Frank S. Nugent (1908–1965)
