PPA go south
 

Yet again, my memory is poor: looking at the authors book, Popski took his own army - the PPA - via the Gilf mountains on the way to the Kufra Oasis. This was with a handful of jeeps and trucks, navigating new territory for all of them. In effect he used the Gilf as a landmark in finding his way to the Oasis.

The "Easonsmith" (of the LRDG) trip was an earlier trip of shorter distance which took a route that lay much further north but it was sufficient to penetrate the German lines in and around the Jebel Akhdar.

Richard's weblink is correct but it is summarising a few books, not just Peniakoffs. It is an interesting summary in itself.
