Operation Compass

Operation Compass was the first major World War II Allied military operation in the Western Desert Campaign. It resulted in British Commonwealth forces pushing across a great stretch of Libya and capturing over 100,000 Italian and Libyan soldiers with very few casualties of their own.

Prelude

After the Italian declaration of war on France and the United Kingdom on 10 June 1940, the Italian forces in Libya and the Commonwealth forces in Egypt began a series of cross-border raids. Among the more notable achievements of these raids were the capture of Fort Capuzzo by the British Army's 11th Hussars on 17 June. One early British raid on 12 June resulted in 63 Italians being taken prisoner. Benito Mussolini urged the Libyan Governor-General Marshal Italo Balbo to launch a large scale offensive against the British in Egypt. Mussolini's immediate aim was to capture the Suez Canal, ultimately wanting to link up his forces in Libya with those in Italian East Africa

Initially the British Middle East Command under General Archibald Wavell only had 30,000 troops stationed in Egypt to defend against the 150,000 Italian troops stationed in Libya. Airplanes available to both sides in the desert tended to be older biplanes. The Italians had Fiat CR.32s and Fiat CR.42s while the British had Gloster Gladiators. The British also several warships to bombard Tobruk and Bardia.

Graziani expressed doubts about the capabilities of his larger but largely un-mechanized force to defeat the British, who, though smaller in numbers, were largely mechanized. Graziani's one mobile group was the partially motorized and lightly armored "Maletti Group". This group was commanded by General Pietro Maletti. But even this group was short on transport vehicles. Maletti Group's tanks were mostly machine gun-armed Fiat L3s tankettes. His heaviest tank type was the Fiat M11/39. This tank featured a relatively weak hull-mounted 37 mm tank gun, and their numbers were small. In comparison, the British were able to field some faster Cruiser tanks (A9s, A10s, and A13s) which were more than match to the M11/39s. The British also had a limited number of heavy Matilda Infantry tanks that, while slow, were strongly armored and well armed. The armor of the Matilda tanks could not be pierced by any of the available Italian tank guns or anti-tank guns available at that time though Italian anti-aircraft guns could be used against them in the same manner as the German 88 mm.

The Italian invasion of Egypt

Even so, Graziani followed Mussolini's orders and the Tenth Army attacked on 13 September 1940. The Italian troops advanced over the Libyan/Egyptian border into Egypt. In addition to several infantry divisions and the Maletti Group, the seven attacking divisions included most of the available Libyan units. The Savari formed part of the Regio Corpo Truppe Coloniali della Libia (Royal Corps of Libyan Colonial Troops), which included desert and camel troops, infantry battalions, artillery and irregular cavalry ("Spahis").

After recapturing Fort Capuzzo, progress was slow. The Italians advanced approximately 95 kilometers in three days. The advance stopped at the town of Sidi Barrani on September 16. The Italians then dug in, fortified their positions, and awaited reinforcements and supplies.

According to Virginio Gayda, Italian newspaper editor and mouthpiece for Mussolini's fascist regime: "Nothing can save Britain now."

However, the British Navy had transferred assets, including the aircraft carrier HMS Illustrious to the Mediterranean, making provisioning of North Africa problematic for the Italians.

British response

Following the Italian advance, Wavell ordered the commander British Troops Egypt, Lieutenant-General Sir Henry Maitland Wilson to plan a limited operation to push the Italians back. Operation Compass was originally planned as a five day raid but was extended after its initial success. On December 8 1940 the Western Desert Force under the command of Major-General Richard O'Connor and comprising British 7th Armoured Division and Indian 4th Infantry Division reinforced by British 16th Infantry Brigade attacked. O'Connor's forces were able to get to the rear of the Italian positions via a gap in the defenses south of Sidi Barrani. A key role in the planning of the operation (and discovery of the gap) is often credited to Brigadier Eric Dorman-Smith.

As a counter-espionage measure, many of the troops involved in Operation Compass were not informed that the operation was not an exercise until they were very nearly engaged in combat. The attack was supported by 25 Pounder artillery, Blenheim bombers, and Matilda Mk.II tanks.

The opening stage of Operation Compass was known by the Italians as the "Battle of the Marmarica". The British knew it as the "Battle of the Camps". The "Battle of the Marmarica" name was derived from the name of the coastal plain where the battle was fought. The "Battle of the Camps" name was derived from the individual Italian camps set up in a defensive line outside of Sidi Barrani.

The Italian defenses were better suited to a colonial war. Within five hours of the onset of combat, the Italian positions were over run, General Pietro Maletti was dead, and about 4,000 Italian and Libyan soldiers were dead or captured. Over the next few days the British 4th and 7th Armoured Brigades encountered significant resistance and found it extremely difficult to advance. Due praise went to Italian anti-tank and artillery gunners who managed to destroy eighteen British tanks but eventually, 237 artillery pieces, 73 light and medium tanks, and about 38,300 Italian and Libyan soldiers would be destroyed or captured. The Rajputana Rifles had lost 41 officers and 394 men killed and wounded in the attacks and dozens of British tanks had been destroyed or disabled. The British and Indian forces having licked their wounds then moved quickly west along the Via della Vittoria, through Halfaya Pass, and again captured Fort Capuzzo in Libya.

O'Connor wanted to continue attacking. He wanted to get at least as far as Benghazi. However, on December 11 General Wavell had ordered the Indian 4th Infantry Division to take part in an offensive against Italian forces in Italian East Africa. O'Connor would state, "[This] came as a complete and very unpleasant surprise . . . It put 'paid' to the question of immediate exploitation . . . ". The Australian 6th Division replaced the Indian troops from December 14. The Australians had barely finished training, were missing their armoured regiment, and as yet had only one artillery regiment equipped with the new 25 pounder field guns.

US War Correspodent Edward Kennedy reported that the 4th Blackshirt Division fought well in defence of the Maktila positions:

"With the dawn the British column, made entirely of English and Scottish regiments—started for Sidi Barrani with tanks leading the way ... Two-thirds of a mile south of the town they came under the fire of Italians entrenched on a ridge ... After seven hours of hard fighting, in which the British said the Blackshirts fought well and inflicted considerable casualties, the British drove them back and took the ridge at 2 pm."
