The Mareth Line was a system of fortifications built by France in southern Tunisia in the late 1930s. The line was intended to protect Tunisia against an Italian invasion from its colony in Libya. The line occupied a point where the routes into Tunisia from the south converged, leading toward Mareth, with the Mediterranean Sea to the east and mountains and a sand sea to the west.
The line ran along the north side of Wadi Zigzaou for about 50 km (31 mi) south-westwards from the Gulf of Gabès to Cheguimi and the Djebel (mountain) Matmata on the Dahar plateau between the Grand Erg Oriental (Great Eastern Sand Sea) and the Matmata hills. The Tebaga Gap, between the Mareth line and the Great Eastern Sand Sea, a potential route by which an invader could outflank the Mareth line, was not surveyed until 1938.
After the French
The Battle of Medenine (6 March 1943) against the Eighth Army was a costly failure. At the Battle of the Mareth Line (16–31 March 1943) the Eighth Army was contained within the Mareth Line defences. An outflanking move west and north of the Mareth Line was followed by Operation Supercharge II which broke through the Axis defences of the Tebaga Gap and led them to retreat from the Mareth Line to Wadi Akarit. The Mareth Line is derelict and is commemorated at the Mareth Museum.

Geography
Central Tunisia is dominated by the Atlas Mountains, while the northern and southern portions are largely flat. The primary feature in the south is the Matmata Hills, a range running north-south roughly parallel to the Mediterranean coast. West of the hills, the land is the inhospitable Jebel Dahar and the Dehar region of desert beyond to the west, making the region between the hills and the coast the only easily traversed approach to northern Tunisia.[4] A smaller line of hills runs east–west along the northern edge of the Matmata range, further complicating this approach. At the far northern end of the Matmata Hills is the Tebaga Gap. From the Mediterranean the coastal plain rises gently to the Matmata Hills. The plain consists of gravels and sands, with salt flats between the sandy areas, which turn into bogs after light rain becoming impassable to wheeled vehicles. There are numerous wadis from the hills to the sea, including the bigger Wadi Zeuss and Wadi Zigzaou. Inland, the sources of the wadis are steep and rocky, widening near the coast, the beds having streams or muddy bottoms, with firmer areas traversable by vehicles.[5]
Plans
In January 1934 planning began on the new fortifications; Infantry officers selected the sites for strongpoints to dominate the ground in front with overlapping fields of fire. In 1936, the French government provided funds for construction after Italy formed the Rome–Berlin Axis with Germany, creating a greater threat to French security in North Africa.[6][b] The casemates designed for the line had much less concrete than comparable examples in France and had no fossé (gap) rather a stable door, in case the lower part was blocked by débris. In September 1936, during a meeting with General Joseph Georges, it was agreed that the fortification of the Mareth Line, Bizerte, Medenine, Ben Gardane and Foum Tataouine (Tataouine) must be completed. Medenine, Ben Gardane to the west and Tataouine to the east, were south of the proposed line, Tataouine being the place where the routes to Mareth passed through the bottleneck between the Matmata Mountains and the sea.[6]
The line was divided into eastern and western sectors with a main line of resistance and a reserve line about 0.93 mi (1.5 km) back. A secteur défensif (SD) was to be built on the rocky Dahar Plateau, which later became part of an SD across the Matmata Hills to Kebili on the edge of the Chott el Djerid. The chott and Chott El Fedjaj drained across Tunisia into Wadi Akarit, across Tunisia but Wadi Akarit was only sketchily fortified, the French concentrating on the Mareth Line 31 mi (50 km) south, to cover Gabes.[6] The gap between the Mareth Line and the Great Eastern Sand Sea, a potential route by which an invader could outflank the Mareth line, was not given consideration until 1938. General Georges Catroux and Colonel Gautsch surveyed the area and in their assessment predicted that three divisions could advance from the Libyan border to Ksar (fortified village) el Hallouf and Bir (well) Soltane in six days and then advance into the gaps either side of Djebel Melab and those between Djebel Tebaga and the Matmata Hills. [7]
Mareth Line
The Mareth Line consisted of casemates surrounded by barbed wire and built for all-round defence in the main and reserve lines, the obstacles being doubled on the fronts and sides. The strongpoints in the main line included flanking machine-gun casemates and anti-tank gun positions; in the reserve line artillery emplacements provided covering fire in the gaps between the strongpoints in the main line. Some of the flanking casemates for machine-guns covering the gaps were connected by galleries; strongpoints on the plain and in hills had anti-tank positions. An anti-tank obstacle of vertical rails was built along the front of the line and the sides of Wadi Zigzaou were steepened. Eight artillery casemates, forty infantry casemates or blockhouses and fifteen command posts were built. The eastern sector had twelve strongpoints in the main line and eleven in the reserve line. The western sector had eleven strongpoints in the main line and seven in the reserve line.[6]
In the Matmata hills, Ksar el Hallouf covered an anti-tank ditch which continued the position beyond the main line which ended on the foothills. An infantry position was dug into the Matmata hills at Ksar-el-Hallouf and in the Dahar beyond, a strongpoint at Bir Soltane had two 75 mm turrets, removed from Char 2C tanks built in 1918. At Ben Gardane an advanced position was built consisting of a square redoubt inside an anti-tank ditch with casemates on the flanks and concrete infantry shelters. Small triangular strongpoints at the corners were surrounded by anti-tank rail obstacles that continued around the position. The Mareth line was equipped with obsolescent 75 mm and 47 mm naval guns for anti-tank defence and a few new 25 mm anti-tank guns and infantry small arms. The artillery casemates with 75 mm guns and most of the blockhouses and casemates had embrasures for automatic weapons. In 1938 work the Mareth line was so important that work on coast defences was stopped and in 1939 the line was occupied by colonial divisions and some locally raised units. After the outbreak of the war, a line of advanced positions (avant-postes) was built on high ground at Aram 6.2 mi (10 km) south of the main line.[6]

Notes
- ^ Two of the infantry divisions were transferred to France from 21 May 1940 and by 7 June the French force had been reduced to four infantry divisions, fortress troops and local cavalry.[3]
- ^ The cost of the Mareth Line and its forward defences was similar to that of Ouvrage Sainte-Agnès in the Alps.[6]
- ^ The Raggruppamento Sahariano consisted of two battalions of Infantry Regiment 350, three companies of the Novara Group, a Frontier Guard battalion, a battalion from the "Savona" Division, a machine-gun battalion, four Saharan companies and nine troops of artillery.[11]
