It happened in the 1840s in Uruguay. The Uruguayan Navy was desperate. They were fending off the navy of an aggressive force from Argentina. They ran out of conventional ammunition and thought their cause was lost. Someone came up with a creative idea. They would use old cheese as ammunition. So they raided the kitchen and loaded their cannons with old, hard Edam cheese and used it as cannonballs. Incidentally, they won the battle.
Is it possible for us to take good things and turn them into weapons? Words can be used to edify or to destroy.
