Edward Everett Hale - The Man Without a Country (1863)
2 Sourced Quotes
No matter what happens to you, no matter who flatters you or who abuses you, never look at another flag, never let a night pass but you pray God to bless that flag. Remember, boy, that behind all these men you have to do with, behind officers, and government, and people even, there is the Country Herself, your Country, and that you belong to Her as you belong to your own mother. Stand by Her, boy, as you would stand by your mother, if those devils there had got hold of her today.
Edward Everett Hale
