Clever Use of Events
Sefton Delmer wanted the printed leaflets and stickers to back up his radio shows. The printed leaflets or stickers would have some news or rumours that were the same or similar to what was being broadcast on the relevant show at the time. Printed material was distributed by air drops, carried by plane and dropped wrapped around special bombs giving a crinkled effect. British agents and resistance movements in Germany and other occupied European countries also helped distribute the leaflets, at great cost to their own personal safety. If they had been caught they would have been shot.
A famous German pilot, who had been awarded the highest German military medal, the Iron Cross, was on his way to Berlin to attend the funeral of another great fighter pilot. On the way his plane crashed. About the same time Britain captured another Luftwaffe (German air force) Officer and questioned him about the pilot who had crashed.

It was discovered that he was a a Roman Catholic. This news reached Sefton Delmer who at the time was saying in his radio shows that Hitler and his Generals were anti religion. In the radio show 'Der Chef' made up the story that the plane flown by the Catholic German had been shot down by Himmler’s troops (one of Hitler's generals). This was followed up with leaflets dropped near to German aircraft bases.
The Iron Cross
The leaflets were cleverly produced on what looked like ordinary German Luftwaffe forms. The contents was supposedly written by the crashed pilot before he died, talking about his faith in the Catholic church. The leaflet was copied and soon spread a long way across Germany. The German authorities did not realise it came from Britain, they thought it had been produced by an anti-nazi German pilot.

The contents of the leaflet caused a lot of resentment amongst the Roman Catholic Germans, and was even read out in the pulpit by several Catholic priests. To add to the story Delmer even invented a sister for the crashed pilot who was a nun. It was broadcast that the convent where the nun lived had been commandeered by Hitler's soldiers, not true of course.

The Germans were so convinced of this whole story that they interrogated the crashed pilots mother, who claimed the letter was a forgery. Needless to say this piece of propaganda was considered to be a success.
