Tiefenbrunner account of SIG

In January 1999, Maurice (Monju) Tiefenbrunner, a surviving member of SIG, recorded his life story in an unpublished autobiography booklet called "A Long Journey Home". On pages 37–41, he provides information on SIG unit formation and operations. A sample scan of the first pages is shown to the right.

After the SIG was disbanded, Tiefenbrunner was caught by the Italians, and sent to a POW camp in Italy. He was moved to a POW camp in Nazi German territory, where he met Vic Crockford. They were released in early 1945.
