Battle of Mareth Line

The Battle of the Mareth Line or the Battle of Mareth was an attack in the Second World War by the British Eighth Army in Tunisia, against the Mareth Line held by the Italo–German 1st Army. It was the first big operation by the Eighth Army since the Second Battle of El Alamein 4+1⁄2 months earlier. On 19 March 1943, Operation Pugilist, the first British attack, established a bridgehead but a break-out attempt was defeated by Axis counter-attacks. Pugilist established an alternative route of attack and Operation Supercharge II, an outflanking manoeuvre via the Tebaga Gap was planned. Montgomery reinforced the flanking attack, which from 26 to 31 March, forced the 1st Army to retreat to Wadi Akarit, another 40 mi (64 km) back in Tunisia.
