Operation Compass. It was the first major Allied offensive of the Western Desert Campaign during the Second World War. Launched by the British-led Western Desert Force against the numerically superior Italian Tenth Army in Egypt and Libya, the operation achieved a spectacular and unexpected success. The rapid advance resulted in the complete destruction of the Italian army in Cyrenaica and a deep thrust into Italian Libya.

Background

Following Italy's declaration of war on France and the United Kingdom in June 1940, the Italian Tenth Army, under Marshal Rodolfo Graziani, advanced from Italian Libya into Egypt in September. This cautious advance, known as the Italian invasion of Egypt, halted after about 60 miles at Sidi Barrani, where the Italians established a series of fortified camps. The British Middle East Command, led by General Archibald Wavell, maintained a defensive posture with the Western Desert Force under Lieutenant-General Richard O'Connor. With the Battle of Britain ongoing, Wavell saw an opportunity to strike a decisive blow against the overextended Italian positions to secure Egypt and the vital Suez Canal.

Planning and forces

The plan, conceived by Wavell and O'Connor, was a limited five-day raid to destroy the Italian camps around Sidi Barrani. The core of the assault force was the British 7th Armoured Division and the Indian 4th Infantry Division, later replaced by the Australian 6th Division. Commanded by Major-General Iven Giffard Mackay, the Australian division would play a crucial role. Opposing them was the dispersed Italian Tenth Army, commanded by General Italo Gariboldi, with its main combat formations including the Libyan Corps and the XXI Corps. Despite having significant numerical superiority in men, tanks, and artillery, the Italian forces were poorly deployed, with large gaps between their fortified positions.

Initial attacks and the capture of Sidi Barrani

Operation Compass began on the night of 8–9 December 1940. Under cover of a severe sandstorm, the Western Desert Force infiltrated the gap between the camps at Nibeiwa and Rabia. The Indian 4th Infantry Division, supported by Matilda tanks from the 7th Royal Tank Regiment, launched a surprise dawn assault on the fortified camp at Nibeiwa, overwhelming the Maletti Group. This success was swiftly followed by attacks on the camps at Tummar West and Tummar East. Within three days, the British forces had shattered the Italian defensive line, leading to the fall of Sidi Barrani itself on 10 December. The rapid collapse forced the remnants of the Italian Tenth Army into a full retreat back towards the Libyan border.

Pursuit and the Battle of Bardia

Exploiting the rout, O'Connor ordered an immediate pursuit with the British 7th Armoured Division. The Australian 6th Division was brought forward to assault the next major obstacle: the fortified port of Bardia, defended by General Annibale Bergonzoli's XXIII Corps. The Battle of Bardia commenced on 3 January 1941. Following a heavy bombardment, Australian infantry breached the perimeter, supported by British tanks and artillery. After three days of intense combat, the garrison surrendered on 5 January, yielding over 40,000 prisoners, hundreds of guns, and valuable supplies.

Fall of Tobruk and advance to El Agheila

The offensive continued relentlessly. The vital port of Tobruk was the next objective, defended by elements of the Italian Tenth Army's XXII Corps. The Australian 6th Division attacked on 21 January, and the Italian garrison capitulated within 24 hours, capturing 25,000 more troops. O'Connor then orchestrated a daring flanking maneuver across the desert via Mechili to cut off the Italian retreat at Beda Fomm. The decisive Battle of Beda Fomm on 5–7 February 1941 saw the remnants of the Italian Tenth Army trapped between the advancing Australian 6th Division and the blocking force of the British 7th Armoured Division. The destruction of the Italian force allowed the Allies to advance unopposed to El Agheila in central Libya by 9 February.

Aftermath and significance

Operation Compass was a stunning tactical and operational triumph. In just two months, a force of never more than two divisions destroyed ten Italian divisions, advanced over 500 miles, and captured over 130,000 prisoners. The victory secured Egypt and eastern Libya for the Allies and demonstrated the effectiveness of combined arms warfare and aggressive maneuver. However, its strategic impact was limited by the subsequent Balkans Campaign and the diversion of resources to Greece, which weakened the Allied position in North Africa. This vacuum facilitated the deployment of the German Afrika Korps under Erwin Rommel, setting the stage for the prolonged and bitter North African Campaign that would follow.
