Hard Tack

a large, hard biscuit or cracker, made for the use of soldiers on the march, It takes 14 of them to make a pound. About 20 of these crackers are served to each man every day. When the soldiers were about to be shipped from Tampa to Cuba, during the war with Spain (1898), two factories in Atlanta furnished the government in two days with 80,000 pounds or 1,120,000 of hard tack.
