The Tebaga Gap of southern Tunisia is a low mountain pass located in rough rocky broken country giving entry to the inhabitable and inhabited coastal plain to the north and east from much less hospitable desert dominated terrain in southern and south-western Tunisia.
The pass separates the Matmata hills to the east running roughly north to south from the Djebel Tebaga hills, another line of high ground to the west of the gap running east-west. The combined terrain of the region about the pass was of critical importance shaping the battlegrounds, strategy and tactics used thereabouts during several years of fighting in North Africa during World War II.
North and west of this region is the great salt lake known as the Chott el Djerid or Chotts. West of the Matmata Hills, the terrain is dry country, the Dahar, and then impassable sand of the Grand Erg Oriental. The Oasis town of Gabès lies on the coast where the coastal plain meets the route from the Tebaga Gap. North of Gabès, the road to Sfax, an ancient caravan route to Libya and points east—and that likely even in Egyptian times—passes between the sea and the Chotts and this was Montgomery's only route north, a way blocked by the Mareth Line. Much of the buildings in the region are subterranean because of the harsh desert temperature changes and lack of moisture.
