The Italian conquest of British Somaliland (Italian language: conquista italiana della Somalia britannica ) was a military campaign in the Horn of Africa, which took place in August 1940 between forces of Italy and those of Great Britain and its Commonwealth. The expedition formed part of the East African Campaign.


When Italy declared war on 10 June 1940, the Italian troops were not prepared for a prolonged war in North Africa or East Africa. As a consequence, Italian dictator Benito Mussolini ordered only some limited aggressive actions to capture territory along the borders of Egypt, Kenya, and Sudan.

Later in June, Amedeo, Duke of Aosta—the Governor-General and Viceroy of Italian East Africa, convinced the Italian Supreme Command (Comando Supremo) to plan a campaign to conquer British Somaliland. Victor Emmanuel III—the King of Italy—and Mussolini agreed with the Duke of Aosta and by the beginning of August the campaign was ready to commence.

Order of battle

The Italian force attacking British Somaliland in August 1940 was commanded by Lieutenant General Guglielmo Nasi, General Officer Commanding Eastern Sector.[7] The force included twenty-three colonial battalions of regular native troops in five brigades, three Blackshirt battalions,[7] and three bands (bande) of dubats and other locally recruited irregulars.[8] The Italians also had armoured vehicles (a small number of both light and medium tanks), artillery, and, most important, superior air support. The Italians numbered about 24,000.

On Italy's declaration of war in June 1940, the British forces in Somaliland had been placed under the command of Lieutenant-Colonel Arthur Reginald Chater, the commander of the Somaliland Camel Corps.[9] At the start of August, the newly promoted Brigadier Chater[9] commanded a contingent of about 4,000 soldiers comprising the lightly armed Somaliland Camel Corps, the 2nd (Nyasaland) Battalion King's African Rifles (KAR), the 1st Battalion Northern Rhodesian Regiment (KAR), the 3/15th Punjab Regiment and 1st East African Light Battery (four 3.7 in (94 mm) howitzers). They were joined from Aden on 7 August by the 1/2nd Punjab Regiment and 8 August by 2nd Battalion Black Watch.[10][11][12] Chaters' force was not only critically short of artillery but it had no tanks or armoured cars nor did it have any anti-tank weapons to oppose the Italian medium and light tanks.

Initial offensive

In the early hours of 3 August 1940, the Italian Army crossed the border between Italian East Africa (called by the Italians Africa Orientale Italiana, AOI) and British Somaliland.[13]

Because of the rugged hills (rising to over 4,500 ft (1,400 m)) which run parallel to the coast some 50 mi (80 km) inland there were three approaches to Berbera, the capital of British Somaliland and the only port of consequence, which would support the passage of wheeled and tracked vehicles.[10] The most direct route with the widest pass was via Hargeisa.

As a consequence, the Italians advanced with three columns along these three routes. The western column advanced toward the small port of Zeila near the border with French Somaliland, the centre column toward Hargeisa and Adadlek and the eastern column toward Odweina and Burao.[14]

The Italian plan was for the western column to seal off French Somaliland[nb 5] and then send light forces eastwards. The central column would establish a base at Hargeisa and then carry the main weight of the attack through the Mirgo Pass towards Berbera. The eastern column would move to Odweina to cover the central column's flank and be prepared to link up with it if necessary.[7]

On 5 August, the port of Zeila was occupied by the Italian western column commanded by Lieutenant-General Bertoldi.[7] Any possibility of help from French Somaliland for the British was eliminated. As planned small forces then proceeded southeast along the coast and occupied the village of Bulhar.

The Italian central column—commanded by Lt-Gen Carlo De Simone—faced more difficulties because of the mountainous terrain through which it advanced. The column was held up at Hargeisa by the Camel Corps assisted by a company of the Northern Rhodesia Regiment, but De Simone brought up some light tanks, and by 5 August the opposing troops had fallen back. De Simone took two days to reorganise his supply position at Hargeisa and then resumed his advance through the Karrim Pass toward the Tug[nb 6] Argan, a dry sandy river bed, in the Assa Hills.[7]

The eastern column, under Brigadier General Bertello and comprising mainly irregular troops, reached Odweina on 6 August and then headed north west toward Adadle a village on the Tug Argan.[7]

Brig. Chater used his Camel Corps supplemented by small patrols of the Illalos (a small force of tribal levies normally employed on police duties)[10] to skirmish with and screen against the advancing Italians as the other British and Commonwealth forces pulled back towards Tug Argan.

Battle of Tug Argan

By 10 August, De Simone had closed up on the British positions behind the Tug Argan and made his preparations to attack.

On 7–8 August, the British and Commonwealth forces in British Somaliland had received reinforcements with the arrival of the 1/2nd Punjab Regiment and the 2nd battalion Black Watch.[10][12] General Archibald Wavell—Commander-in-Chief Middle East Command in Cairo—had also ordered a further battalion of infantry and more artillery to Berbera but these reinforcements did not arrive in time.[16] He also considered it appropriate to appoint a major-general to command this expanding force and on 11 August, a new commander—Major-General Reade Godwin-Austen—reached Berbera.[16]

The defensive positions of the British army were centered around six hills overlooking the only road toward Berbera. On 11 August, one of De Simone's brigades attacked the hill defended by a company of the 3rd Battalion 15th Punjab Regiment and captured it,[17] taking heavy casualties. The British launched two unsuccessful counterattacks but fought off Italian attacks on two other hills. The next day, all the British positions were attacked. By evening, Mill Hill had been taken from the Northern Rhodesian Regiment after severe fighting. More critically, two of the scarce East African Light Battery howitzers were lost and Italian forces had established themselves in the Assa Hills, dominating the southern side of the gap through which the road to Berbera ran.[17]

On 13–14 August, no further positions were taken despite heavy fighting but the Italians continued to improve their position through infiltration. By 14 August, the defenders' situation started to look critical: the Italians were almost in a position to cut the road and thus the defenders' only line of supply and retreat. On 14 August, Godwin-Austen informed Middle East Command of the situation concluding that further resistance at Tug Argan would be futile and likely to result in the loss of the whole force. He believed that a withdrawal would result in 70% of the force being saved.[17] On 15 August, he received orders to withdraw his forces from British Somaliland.[18]

Late on 15 August, the Italians took Observation Hill and after dark the defenders of Tug Argan commenced their withdrawal. The Black Watch together with two companies of the 2nd KAR and elements of 1/2nd Punjab Regiment formed a rearguard position at Barkasan on the Berbera road some 10 mi (16 km) behind the Tug Argan position.[18]

British evacuation from Berbera

While the British made their retreat to Berbera, the Royal Navy had constructed an all-tide jetty and had commenced evacuating civilian and administrative officials. On 16 August, the British started to embark troops onto the waiting ships.[19]

On 17 August, an Italian column was reported at Bulhar, some 40 mi (64 km) west of Berbera. The light cruiser HMS Ceres—patrolling off the coast—engaged the column and halted it.[20] De Simone's forces advancing from Tug Argan were very cautious and did not attack the Barkasan rearguard until late morning on 17 August[20] when they were held by determined resistance including a fierce bayonet charge by the Black Watch.[8] After dark, the rearguard was withdrawn to Berbera. The entire British and Commonwealth contingent withdrew to Berbera with minimal losses and loading of the ships was completed in the early hours of 18 August, although HMAS Hobart—with the force headquarters aboard—remained at Berbera to collect stragglers and continue the destruction of vehicles, fuel and stores until the morning of 19 August[20] before sailing for Aden.[18] Three Australians from HMAS Hobart missing feared dead were to become the first Australian WW2 POWs.[citation needed] In total, 7,000 people, including civilians, were evacuated.[21] The local Somalis of the Somaliland Camel Corps had been given the choice of evacuation or disbandment and the large majority chose to remain and were allowed to retain their arms.[20]

The British defenders had little interference in this operation. It is possible that this was because on 15 August, the Duke of Aosta had ordered Gen. Nasi to allow the British to evacuate without too much fighting. He did this in the hope of a possible future peace agreement, that was being promoted through the Vatican mediation, between Italy and Great Britain.[22]

On 19 August, the Italians took control of Berbera and then moved down the coast to complete their conquest of British Somaliland. The British colony was annexed by Mussolini to the "Italian Empire" as a part of Italian East Africa.[23]


According to Italian historians,[24] during the campaign to conquer British Somaliland the casualties were 250 for the British army and 205 for the Italian. However, according to the British official History of the Second World War total British casualties were 260 and Italian losses were estimated at 2,052[25]

Unofficially, De Simone estimated that nearly one thousand irregular Somalis fighting against the Italian invasion were casualties during the campaign. These armed men operated as local "Bande", with only minimal control from British officers (like Brigadier Chater).[6] Lieutenant-General Luigi Frusci—commander of the Italian East Africa Northern Sector—also referred to these thousand casualties in his writings, and believed that the Somalis fighting as "armed Bands" on the Italian side suffered two thousand casualties (the most popular local tribal chief - named Afchar - greeted the Italians after the conquest of Zeila and offered his men against the British[nb 7]).

The Somali irregulars fighting against the British were the descendants of the Dervish fighters of Mohammed Abdullah Hassan (called Sayyid Mohammed Hassan by Somalis and the "Mad Mullah" by the British), a prominent Somali rebel against the British colonial occupation of Somaliland in the 19th century. Indeed, at the beginning of 1920, the British struck the Dervish settlements with a well-coordinated land, sea and air attack and gave them a decisive defeat. The forts of Sayyid Mohammed were damaged and his army suffered great losses. They hastily fled to Ogaden. Here, he tried to rebuild his army and create a coalition of Ogadeen clans which would make him a power in Somaliland once again. Sayyid died in 1921, however, and the British maintained the Somaliland albeit with frequent local rebellions. On the other side, there were many irregulars (Ethiopians and Somalis) fighting a guerrilla war in Ogaden (and even in deserted eastern Somaliland) against the Italians after their conquest of Ethiopia in 1936.[citation needed]


The port of Berbera was used by the Italian submarines of the Red Sea Flotilla as a small base in the last months of 1940.[citation needed]

The British Prime Minister—Winston Churchill—criticised Gen. Wavell concerning the loss of British Somaliland. It was Wavell's Middle East Command which was responsible for the loss of the colony. Because of the low casualty rate, Churchill fretted that the colony had been abandoned without enough of a fight and proposed a court of enquiry. In response to this criticism, Wavell claimed that Somaliland was a textbook withdrawal in the face of superior numbers. He pointed out to Churchill that "A bloody butcher’s bill is not the sign of a good tactician." According to Churchill's staff, Wavell's retort moved Churchill to greater fury than they had ever seen before and probably marked the start of the decline of Wavell's position with Churchill that led to his dismissal.[26][27]

British Somaliland remained part of Italian East Africa for a matter of months. On 16 March 1941, the British executed Operation Appearance which was staged from Aden; two battalions from the Indian Army and one Somali commando detachment were landed on both sides of Berbera.[28] The two Sikh battalions (which had been part of the defending force evacuated in August 1940), made the first successful Allied landing on an enemy-held beach during World War II. Shortly afterwards the British and Indians re-captured the whole of British Somaliland from its Italian occupiers.[27]

One important consequence was written on Time magazine: "The Britons' greatest loss was in prestige, especially among Arabs."[29]


The conquest of the British Somaliland was the only campaign victory Italy achieved — without the support of German troops — during World War II against the Allies.

The campaign in Somaliland was like all the others of the Axis: it initially started with a victory, then after a period of time (like the campaigns in the Balkans, in the Philippines or in Russia), finished with a complete defeat. But in the specific case of the Italian conquest of British Somaliland, the defeat (that happened in spring 1941) was followed by nearly two years of Italian guerrilla warfare.[30]

Other observations are:[citation needed]

  • The invasion of British Somaliland showed that Italian forces could co-ordinate columns separated by many miles of desert.
  • British forces showed good discipline in the retreat and were able to salvage most of their forces.
  • The invasion of British Somaliland was the first campaign the Italians won in World War II.
  • British Somaliland was the first British colony to fall to enemy forces in World War II.
  • After the first months of the war were over, Mussolini boasted that Italy had conquered a territory (made of British Somaliland, the Sudan area around the border outposts of Karora, Gallabat, Kurmak and Kassala, and the area in Kenya around Moyale and Buna) the size of England in the Horn of Africa.
  • The campaign of British Somaliland in August 1940 was the only one in which the British army could not get strong support from the Royal Air Force, showing the importance of the air forces in the Allies' victories.[30]

According to Wavell the total casualties of the British forces (including Indian and African troops) of 258 amounted to "...little more than five per cent of the force."[1] This implies a total force of about 5,000. Molinari's book estimates the British forces at 11,000[2] but it can normally be assumed that Italian sources are more accurate for Italian forces and British sources for British forces.
  2. According to Wavell almost half the casualties were from the Northern Rhodesia Regiment and he believed that the great majority of the missing had been killed.[1] It subsequently transpired that most of the missing had been taken prisoner.[3]
