"Hard Tack, Come Again No More" is an American Civil War-era parody of the song "Hard Times, Come Again No More." First called "Hard Crackers, Come Again No More!", it is a sarcastic complaint about the quality of some of the provisions provided by military contractors.
From the Revolutionary War to the Spanish-American War, the United States army ration, as decreed by the Continental Congress, was the garrison ration which consisted of meat or salt fish, bread or hardtack, and vegetables.
