Coordinates: Halfaya Pass (Arabic: مَمَرّ حَلْفَيَا translit. Mamarr Ħalfayā, known colloquially as Hellfire Pass) is located in Egypt, near the border with Libya. A 600 feet (180 m) high escarpment extends south eastwards from the Egyptian-Libyan border at the coast at as-Salum (or Saloum, Solum, Sollum), with the scarp slope facing into Egypt. Halfaya Pass is about two miles 2 miles (3.2 km) inland from the Mediterranean and provides a natural route through.
The escarpment is known as Akabah el-Kebir عقبة الكبير (`aqabat al-kabīr) "great ascent". To El-Edrisi it was known as عقبة السلوم (`aqabat as-salūm) "graded ascent", whence the modern name of the gulf and the town of Salum.
World War II
In World War II, the engineered route up the escarpment had been destroyed and the pass had great strategic importance. The only ways westwards into Libya were to assault the pass or to out-flank it to the south.
After the defeat of the Italian 10th Army on 7 February 1941 during Operation Compass, the Italians were reinforced by German units (Afrika Korps under Erwin Rommel) and the British forces were forced out of Libya, leaving a besieged garrison at Tobruk. On 14 April 1941. Rommel's main force reached Sollum on the Egyptian border and occupied the Halfaya Pass. There were several allied attempts to recapture the Halfaya Pass and relieve Tobruk.
The first attempt, on 15 May, was Operation Brevity. Rommel counter-attacked; the British withdrew and by 27 May the Germans had recaptured Halfaya Pass, a passage of time in which Major Edward Thomas earned his Military Cross. Supply shortages obliged the Germans to curtail their advance, so they dug in and fortified their positions at Halfaya with 88 millimetre guns. This was the anchor for the Axis positions, which opposed the Allied forces during the next allied attack — Operation Battleaxe on 15 June. German armour was deployed to draw the British tanks (11th Hussars) onto the concealed 88mm guns and the first wave was cut down in a few minutes (11 out of 12 tanks were destroyed), earning the pass the nickname "Hellfire Pass". The allied commander, Major Miles, was last heard on the radio reporting, "They are tearing my tanks apart."
The third attempt, Operation Crusader opened on 18 November, with a direct attack on Halfaya Pass and an attempt to outflank Rommel to the south and relieve Tobruk. This was done on 29 November. Rommel, now under pressure, withdrew to El Agheila.
Halfaya Pass was the location of the accidental death of Major-General 'Jock' Campbell (VC), then commander of the British 7th Armoured Division. On 26 February 1942, a month after assuming command, his staff car skidded on a newly laid clay road surface, killing him outright.
