Swiss Cheese is the youngest son of Mother Courage but rather stupid. He gets appointed as a Paymaster for the Finnish regiment and takes his job quite seriously. When he is getting ready to return the cash box to the commanding officer, he is captured by the enemy forces. Mother Courage tries to bargain by haggling over the prices for the release of Swiss Cheese but to no avail. This exposes the value of money over humanity by Mother. Ultimately Swiss Cheese is executed for his trouble.
