It probably has never occurred to you that sausages and Zeppelins are linked together. Actually, cow intestines were used in the production of German Zeppelins and the intestines of 250,000 animals were required for just one airship of this type.
During the World War I the Germans used Zeppelins to bomb England, so a large number of airships had to be manufactured and lots of caw intestines were needed. The guts were used to make special bags to hold the hydrogen in each Zeppelin.
The great demand for intestines called for strict and severe measures. Thus, eating sausages during the war was made illegal. The popular wurst was banned in Germany as well as in the occupied territories in Poland, Austria and France. All butchers were required to provide the intestines from the animals they killed and the government enforced strict and systematic control to make sure no sausages were made and eaten.
