The idea was to bake a load of biologically weaponised cattle cakes (cakes made from linseed and ram-packed full of anthrax instead of icing) and drop them over agricultural areas of Germany. Then, unsuspecting and innocent cows would rush towards the treats thinking they’re about to get a Linzertorte (they’re German, if they’re aware of the concept of cakes they aren’t thinking Eccles) and instead get a tasty mouthful of anthrax.
