Torrie Forest was the location of a U.S. army chemical weapons store (no.25) located at Aberfoyle, near Callander in Scotland during WW 11
The official Operation Cleansweep Report shows that mustard gas (chemical generators) were disposed of by burning. There is barely any other information obtainable to show what went on here.
Today the forest is under the commercial management of the Forest Enterprise and it is popular with walkers, motor sports and mountain biking. However in the last number of years the forest has been heavily harvested and has deterred much of the public from visiting.
