Operation Tamarisk involved agents from the U.S., U.K., and France.
They got many evidences from garbage left behind by Soviet troops stationed in East Germany.
Discarded items included food scraps, letters, military documents, and even used toilet paper.
Intelligence agents found sensitive information scattered among trash heaps.
In some cases, agents retrieved items from hospital waste bins, where discarded limbs provided clues about the types of shrapnel and injuries Soviet soldiers suffered, particularly from their involvement in the war in Afghanistan.
In 1948, the U.S. pilot Gail Halvorsen dropped candy from his plane for children in Berlin during the Berlin Airlift, earning the nickname “The Candy Bomber”.
